Ligusticum is a highly specialized genus in the tribe Ammineae Koch of the
subfamily Apioideae. It is transitional between the tribe Ammineae Koch and the tribe
Peucedaneae DC., and shows a very close affinity to the genus Selinum.
In the present paper, the taxonomic history is reviewed; the external morphology, pollen
morphology and geographic distribution are analysed, and its evolutionary tendencies are
discussed. In addition, a key to the 34 species is provided, and economic uses reported in the
literature are summarized.
Ligusticum consists of over 60 species widely distributed in Eurasia and North America;
the genus is typically temperate. There are two principal distribution centers, one in the
Himalayas, including the Hengduan Mountains of western China, and the other in North
America. Thirty-four species occur in China, most of which are distributed in the alpine belt
of south-western China, with only a few species occurring in northern China. They usually
grow in alpine thicket meadows or in alpine meadows. Among them are 28 species endemic
to China, 4 of which are described as new in the present paper, i. e. L.yuayuanense,
L.litanense, L.filifolium, and L.yunnanense. L.elatum (Edgew.) C. B. Clarke, a species of
India, Afghanistan, and Pakistan, and L. thomsonii C.B.Clarke var. evolutior C. B. Clarke,
of India, Pakistan and Kashmir, are reported from China for the first time.
Some species are important in traditional Chinese medicine, for example, L. sinense
Oliv., L. sinense Oliv. cv. Chuanxiong, L. sinense Oliv. cv. Fuxiong, L. delavayi Franch.,
L. jeholense (Nakai et Kitagawa) Nakai et Kitagawa, L. tachiroei (Franch. et Sav.) Hiroe
et Constance, etc.
The genus Tilingia was established by Regel in 1858, based on Tilingia ajanensis. The
chief characters of the genus are distinct calyx teeth and carpels bearing a solitary vitta in
each furrow. However, these characters do not differentiate Tilingia from Ligusticum, so
that Tilingia was transferred to Ligusticum by Kozo-Poljansky in 1916. Tilingia tachiroei
(Franch. et Sav.) Kitagawa was transferred to Ligusticum by Hiroe et Constance in
1958. Shan et Sheh in “F1. Reip. Pop. Sin.” Tom. 55 supported the treatment by
Kozo-Poljansky and Hiroe and Constance
The genus Ligusticopsis was separated from Ligusticum by Leute in 1969, based on
the prominent calyx teeth of the former. Ligusticopsis included 14 species, all confined
to China. But this genus has not been accepted by any other botanists since its establishment.
The subdivision of Ligusticum in this paper is based mainly on the characters of
involucel bracteoles and mericarps, combined with the shape and aperture types of pollen
grains. The genus is divided into the following two sections.
Sect.1 Ligusticum, Bracteoles linear or lanceolate, entire; mericarps slightly
lateral-compressed to slightly dorsal-compressed; vittae solitary to numerous in each
furrow; leaf-segments ovate, lanceolate, or linear; pollen grains mainly rhomboidal or
ellipsoidal; apertures gonitreme.
Sect. 2 Pinnatibracteola Pu. Bracteoles 1-3-pinnatisect or 2-3-lobed at apex;
mericarps dorsal-compressed; vittae usually numerous in each furrow; leaf-segments
usually linear, rarely ovate or lanceolate; pollen grains rectangular,
elongate-rhomboidal, or equatorially constricted; apertures mainly peritreme, rarely gonitreme or intermediate. 相似文献

In order to clarify the interspecific relationships of a lineage in Pleurospermum, P. hookeri C. B. Clarke, P. yunnanense Franch., and P. giraldii Diels, and to understand intraspecific divergence of P. hookeri, a phylogeographic study was carried out based on 198 individuals from 24 populations. Three chloroplast DNA regions, ndhF-rpl32, trnL-trnF, and trnQ-rps16, were sequenced in the present study. The genetic relationship between P. hookeri and P. giraldii is not as close as previously assumed. Pleurospermum hookeri and P. giraldii may originate from an unknown ancestor located in the Qinling region. Pleurospermum yunnanensewas found to be the closest relative of P. hookeri in all the species included in the phylogenetic analysis. The two haplotypes identified from P. yunnanense are shared with P. hookeri, which is potentially a result of both incomplete linkage sorting and introgression. Three large divergences within P. hookeri were identified, located at the northeastern edge, southeastern edge, and platform of the Qinghai–Tibet Plateau (QTP), respectively. Long-term history can explain the deep intraspecific divergence of P. hookeri. The uplift of the QTP played a key role in that divergence, and then were the climatic changes in the Quaternary. In addition, we found one refugium at the northeastern edge of the QTP, one at the southeastern edge, and at least one in the Hengduan Mountains region on the platform of the QTP. 相似文献

Shih Ghu 《植物分类学报:英文版》1988,26(6):418-428
Having mixed extremely various patterns of achenes for a long time in
the genus Lactuca L., especially showed in the classification of it on the mainland of Asia,
Lactuca L., the primary unnatural genus, becomes more nuclear in its limit. The present
paper makes a revision to attempt providing a clear cline between Lactuca L. and its relative
genera.
On my opinion, only plants, represented by Lactuca sativa L., which have ovoid capitulum during its fruiting, numerous (7-25), yellow ligular florets and longitudinal 1-10 ribs
or striae on each side of achenes, acute into filiform beak at its apex, should be defined as
Lactuca L.
In view of the present concept of Lactuca L., another group of plants, embodied by
Lactuca indica L., having its broadening, thin winged-margin of, 1-3 striae on each side of
achenes, black, dorsi-ventral compressed, acute into thick and short beak at its apex, evidently, should not be placed into Lactuca L., but be regarded as genus, i.e. Pterocypsela Shih,
gen. nov. Pterocypsela Shih distributes in Eastern and southern Asia, where Lactuca L. does
not occur. In China there is all of species, seven species, of Pterocypsela Shih. They are P.
raddeana (Maxim.) Shih, P. indica (L.) Shih, P. elata (Hemsl.) Shih P. lacciniata (Houtt.)
Shih, P. triangulata (Maxim.) Shih, P. sonchus (Lévl.) Shih and P. formosana (Maxim.)
Shih, But in Mediterranean regions and Middle and Western Asia mainly distributes Lactu ca L., in which there are only seven species from western China, Xijiang autonomic district.
They are L. dolichophylla Kitam., L. sativa L., L. altaica Fisch. et Mey., L. serriola Torner,
L. dissecta Don, L. auriculata DC. and L. undulata Ledb.
With the combination of violet-purple ligular florets non-ovoid capitulum during its
fruiting, a little thick achenes, acuminate into longer. or short beak at its apex and 4-6 ribs
on each side of it, Mulgedium tataricum (L.) DC. is evidently different from Lactuca sativa L.
with combination of ovoid capitulum during its fruiting, yellow ligular florets and compres sed achenes, acute into filiform beak at its apex. There seems to be no point in refusing Mu lgedium Cass. as a genus. Strictly speak, Mulgedium Cass. seems to be reminiscent of Para prenanthes Chang (see bellow) without beak at the apex of its achenes. In Hengduan moun tains and mountain range of Himalayas M. tataricum (L.) DC. discoveries its relative par tners. They are M. bracteatum (Mook. f. ex. C. B. Clarke) Shih, M. lessertianum (Wall. ex
C. B. Clarke) DC., M. monocephalum (Chang) Shih, M. umbrosum (Dunn) Shih, M. meridionale Shih and M. polypodifolium (Franch.) Shih.
Having broadering and thickening margin and 4-7 striae on each side of achenes, grey,
dorsi-ventral compressed, truncate and beakless at its apex, Lactuca sibirica (L.) Benth. ex
Maxim. (Sonchus sibiricus L.) is not only different from Lactuca sativa L. with the combination of yellow ligular florets and filiform beak at apex of its achenes, but also from the
genus Mulgedium Cass. with beak at apex of its achenes. Therefore, Lagedium Sojak, established by J. Sojak (1961), should be restored. It should be point out that Lagedium Sojak is monotypic genus excluding Mulgedium tataricum (L.) DC. with beak at the apex of its achenes, non-marginated. Lagedium Sojak widely distributes in temperate and frigid zone ofvnorthern hemisphere. In our country, Lagedium sibiricum (L.) Sojak, sole species of the genus, restricts its northeast region.
Paraprenanthes Chang, the new genus, established by Ch. Ch. Chang (1950) based on Lactuca sororia Miq. and Lactuca yunnanensis Franch. seems to be a distinct genus. This genus is characterized by 4-6 ribs on each side of achenes, black, fusiform, a little thick and
beakless at its apex. Besides above-mentioned two species, assigned by Chang, in forest of tropic and subtropic zones on the mainland of Asia there are many species with same structure
in achenes like L. sororia Miq. and L. yunnanensis Franch. The genus Paraprenanthes Chang
seems to be reminiscants of Mulgedium Cass. and Lagedium Sojak, but differs from the former
in its beakless achenes, from the later in its non-marginated achenes and 4-6 ribs on each
side of it. In our country, there are all species of the genus known in the tropic and subtropic zones on the mainland of Asia. They are P. sororia (Miq.) Shih, P. yunnanensis (Franch.) Shih, P. longiloba Ling et Shih, sp. nov., P. heptontha Shih et D. J. Liou, sp. nov., P.
prenanthoides (Hemsl.) Shih, P. pilipes (Migo) Shih, P. thirionii (Lévl.) Shih, P. sylvicola

The geographical distribution of Liliaceae (s. str. ) is analysed on the basis of the
floristic regions proposed by Takhtajan. Some conclusions may be proposed as follows: 1.Liliaceae (s. str. ) consists of nine genera and about 513 species, distributed primarily in the north temperate zone. Statistics shows clearly that the Irano-Turanian Region is most abundant in number of species, The Eastern Asian Region with total nine genera of the family is the diversity centre of Liliaceae (s. str. ). 2. The distribution patterns of the genera may be divided into: 1 ) North temperate distribution pattern: Lloydia, Erythronium, Fritillaria and Lilium; 2) Old world temperate distribution pattern: Gagea and Tulipa; 3) West Asia to Himalayas and Southwest China distribution pattern: Notholirion; 4) East Asia distribution pattern: Cardiocrinum and Nomocharis. 3. The Sino-Himalayas is one of the key regions in
studying the evolution of Liliaceae (s. str. ) All nine genera occur in the Eastern Asian Region with most species distributed in Southwest and Northwest China. Chorologically, five genera (Fritillaria, Lilium, Cardiocrinum, Nomocharis and Notholirion) of the Lilieae are overlapped each other in the Sino-Himalayas, showing its diversity centre in this region. The Lilieae is a main stock in the Liliaceae (s. str. ), The genus Nomocharis in this tribe may have been newly differentiated from Lilium in the course of the uplift of Qinghai-Xizang Plateau, a view also supported by Xie Xiao-yang et al.. The place of its origin was considered to be in the southern part of the Hengduan Mountains. 4. The distributions of some species in Liliaceae (s. str. ) seem to be significant for dividing some floristic regions: 1 )
Some species of Fritillaria (F. unibracteata Hsiao et K. C. Hsia, F. przewalski Maxim. ex Batal. , F. crassicaulis S. C. Chen, F. cirrhosa D. Don. , F. delavayi Franch. , F. dajinensis S. C. Chen, F. davidii Franch. , F. sinica S. C. Chen and F. sichuanica S. C.Chen) are only distributed in Sino-Himalayan forest subkingdom, while others (F. taiparensis P. Y. Li, F. yuzhongensis S. C. Chen, F. monantha Migo, F. anhuiensis S. C. Chen et S. F. Yin, F. thunbergii Miq. , F. maximowizii Freyn and F. ussuriensis Maxim. ) are restricted to Sino-Japan forest subkingdom. They show a clearly demarcation line between the two subkingdoms, which is identical with what proposed by Wu Cheng-yih. 2) The Eastern Asian Region can be divided into two subkingdoms on the basis of the distribution pattern of the genus Cardiocrinum; C. giganteum (Wall.) Makino and C. gigateum var. yunnanense Leichtlin ex Elwes are restricted to Sino-Himalayan forest subkingdom. C. cathayanum (Wilson) Stearn and C. cordatum (Thunb.) Makino are only found in Sino-Japan forest subkingdom. 3) The distributions of Gagea pauciflora Turcz. , G. triflora(Ledeb.) Roem. et Schult. G. hiensis Pasch, Lloydia tibetica Baker ex Oliver, L. oxycarpa Franch. and L. flavonutans Hara are indicative of a demarcation line between Irano-Turanica Region and Eastern Asian Region. 5. The genus Notholirion occurs in the Eastern Asian Region and Irano-Turanian Region, showing the relationships between the two regions and also between the Chinese flora and Ancient Mediterraneam flora. 相似文献

百合科(狭义)植物的分布区对中国植物区系研究的意义 总被引:27,自引:1,他引:27
本文对百合科(狭义)各属的地理分布作了分析,该科植物集中分布于泛北极域,属于北温带的科。该科所有的9个属,只在东亚区全部有分布,而且该区具有百合科(狭义)植物各系统演化阶段的类群,因此,东亚区是该科的多样化中心。其中百合族所包括的5个属(贝母属、百合属、大百合属、豹子花属和假百合属)集中分布于中国西南至喜马拉雅地区,其分布区均在中国-喜马拉雅地区重叠,表明中国-喜马拉雅地区是百合族的多样化中心。百合族是百合科(狭义)的核心部分。因而认为中国-喜马拉雅地区是研究百合科(狭义)植物演化的关键地区之一。从种类的统计分析表明,伊朗-土兰区分布的种类最多,说明伊朗-土兰区是该科的多度中心.文中还从一些属(贝母属、大百合属、顶冰花属和洼瓣花属)内种的分布,提出可作为划分某些植物区的依据。而且,还从假百合属的分布,阐明中国植物区系与古地中海植物区系的亲缘。 相似文献

Ling Lai-Kuan 《植物分类学报:英文版》1966,11(3):263-342
The genus Eurya was established by Thunberg in 1783 on a Japanese species E.
japonica. Several decades later, many authors had made more or less intensive study on
this genus. But in the earlier period, the different autherities had no clear conception of
the genus. Thus Szyszylowicz (1893), Engler (1897) and Melchior (1925) entertained
a much broader conception of this genus, including Freziera and Cleyera, both of which
are now considered as distinct genera. A. Gray (1855), Vesque (1895), Urban (1896),
and Kobuski (1935-37), however, concentrated their study only on the now accepted
genus Eurya. Recently, a more detailed study of Chinese Eurya was made by Chang
Hung-da (Acta Phytotax. Sin. 3 (1954) 1-59). But all of these authors did not subdivide this genus into more than subgenera except Vesque, who used the number of
stamens and the septation of the anther cells to further subdivide this genus into 4 sections.
In the present treatment, we base on the following characteristics to make subdivisions: the number of stamens, the septation of the anther cells, the hairness of the ovary,
the length of the style, the shape and texture of the sepals, and the shape and hairness
of the young branchlets. We assume that the morphology of the flowers has the following
evolutionary tendencies: stamens from large (28) to small (5) numbers; anther cells from
septate to nonseptate; ovary from being hairy to glabrous, styles from 5-4 free to 3 and
more or less connate, from 2-6 mm to 0.5-1 mm long, and ovules from many (60)
to few (2-4) in each cell.
The genus Eurya has now about 140 species, being divided into 2 subgenera: Subg.
Ternstroemiopsis Urban, with 2 species endemic in Sandwich Islands and Subg. Eurya with
138 species, in Asiatic tropic and subtropic regions and southwestern Pacific Islands.
According to the characteristics mentioned above, we divide the second subgenus into 2
sections and 8 series, as follows:
(I) Sect. Meristotheca Vesque (II) Sect. Eurya
Ser. Ciliatae Hu et L. K. Ling Ser. Longistylae Hu et L. K. Ling
Ser. Trichocarpae Hu et L. K. Ling Ser. Rigidisepalae Hu et L. K. Ling
Ser. Tetragonocladae Hu et L. K. Ling Ser. Nitidae Hu et L. K. Ling
Ser. Muricatae Hu et L. K. Ling Ser. Brevistylae Hu et L. K. Ling
In China, the subgenus Eurya distributes east from Taiwan, west to the western part
of Szechuan and Yunnan, and south from Hainan, north to the southern slope of Tsin-ling
Range. The region north from southern part of Nan-ling Range, southwest to southeast
Yunnan, south to northern part of the Peoples Republic of Vietnam, seems to be the centre
of both maximum variety and frequency of this subgenus, for the number of species and
the representatives of more primitive taxa in this region are much richer than in any
other regions of the world. From this centre going northeast to Japan and Korea, west
to eastern part of India, south to Java and Sumatra, north to the southern slope of Tsinling Range, the number of species and types gradually decreases, and especially the primitive series and species rapidly disappear. In addition, many species are also found in the
Island of Irian, which we incline to consider as another young centre of development for
this subgenus. Furthermore, according to the distribution of quite a large number of the
species in China, we can recognize several boundary lines which are in agreement with the
limits of the floristic and geobotanic provinces of China.
In this article we have enumerated 80 species, and 11 varieties of the genus Eurya
of China, among which are published for the first time 11 new species and 1 new variety,
one species, E. persicaefolia Gagnepain, is first recorded from China, a number of specific
names have been restored and a number reduced to synonyms. They are as follows:
