This paper deals with the taxonomy and geographic distribution of the genus Chrysosplenium L. in China.
Based on the characters and evolution of the seed, capsule, disk, ovary and leaf, the
species of this genus can be grouped into 2 subgenera, 5 sections and 16 series. There
are 2 subgenera, 5 sections and 11 series in China. They are as follows:
I. Subgen. Gamosplenium Maxim. emend. J. T. Pan
Leaves alternate.
Lectotype: Chrysosplenium carnosum Hook. f. et Thoms.
1. Sect. Alternifolia Franch. emend. J. T. Pan
Seeds smooth and glabrous.
Type: Chrysosplenium alternifolium L.
(1) Ser. Nudicaulia Maxim. emend. J. T. Pan
Disk obscure or absent; ovary nearly half-inferior, sometimes mostly inferior; capsule generally subtruncate and emarginate at top and bilobed with equal and horizontally divaricate or suberect lobes; seeds smooth and glabrous.
Type: Chrysosplenium nudicaule Maxim.
(2) Ser. Alternifolia Maxim. emend. J. T. Pan
Disk 8-lobed; ovary nearly half-inferior; capsule generally subtruncate and emarginate at top, and bilobed with equal and horizontally divaricate lobes; seeds smooth
and glabrous.
Type: Chrysosplenium alternifolia L.
2. Sect. Nephrophylloides Turcz.
Seeds minutely papillose or pilose.
Type: Chrysosplenium sedakowii Turcz.
(1) Ser. Macrophylla Franch. emend. J. T. Pan
Disk obscure or absent; ovary nearly half-inferior; capsule nearly truncate and emarginate at top, and bilobed with equal lobes; seeds minutely papillose.
Type: Chrysosplenium macrophyllum Oliv.
(2) Ser. Ovalifolia Maxim. emend. J. T. Pan
Disk generally 8-, rarely 4-, lobed, papillae absent around disk; ovary mostly inferior; capsule subtruncate and emarginate at top; seeds minutely papillose or pilose.
Type: Chrysosplenium ovalifolium M. Bieb. ex Bunge
(3) Ser. Lanuginosa Hara, emend. J. T. Pan
Papillae numerous, brown around reduced disk; ovary mostly inferior; capsule nearly truncate and emarginate at top; seeds minutely papillose.
Type: Chrysosplenium lanuginosum Hook. f. et Thoms.
II. Subgen. Chrysosplenium
Leaves opposite.
Type: Chrysosplenium oppositifolium L.
1. Sect. Trichosperma J. T. Pan, sect. nov.
Capsule not truncate at top, and bilobed with subequal, suberect or divergent lobes.
Type: Chrysosplenium trichospermum Edgew. ex Hook. f. et Thoms.
This section is divided into 4 series in the world, with only 1 in China.
(1) Ser. Nepalensia Maxim. emend. J. T. Pan
Disk obscure or absent; ovary generally mostly inferior; cassule not truncate at
top, and bilobed with subequal and suberect or divergent lobes; seeds smooth and glabrous.
Type: Chrysosplenium nepalense D. Don
2. Sect. Grayana J. T. Pan, sect. nov.
Capsule bilobed with distinctly unequal and ascending lobes.
Type: Chrysosplenium grayanum Maxim.
This section consists of 4 series in the world, with 3 series in China.
(1) Ser. Sinica Maxim. emend. J. T. Pan
Disk obscure or absent; ovary nearly half-superior; capsule bilobed with distinctly
unequal and ascending lobes; seeds minutely papillose.
Type: Chrysosplenium sinicum Maxim.
(2) Ser. Esulcata Franch. emend. J. T. Pan
Disk (4)-8-lobed; ovary generally half-inferior; capsule bilobed with unequal and
ascending lobes; seeds minutely papillose or pilose.
Lectotype: Chrysosplenium dubium J. Gayex DC.
(3) Ser. pilosa maxim. emend. J. T. Pan
Disk obscure or absent; ovary nearly half-inferior; capsule bilobed with distinctly
unequal and ascending lobes; seeds distinctly longitudinally ll-18-costate and minutely papillose or tuberculate on the ridge.
Type: Chrysosplenium pilosum Maxim.
3. Sect. Chrysosplenium
Capsule nearly truncate and emarginate at top, and bilobed with equal and horizontally divaricate lobes.
Type: Chrysosplenium oppositifolium L.
(1) Ser. Romosa J. T. Pan, ser. nov.
Disk distinctly 8-lobed, papillae sparse, brown around disk; ovary mostly inferior; capsule nearly truncate and emarginate at top, and bilobed with equal and horizontally
divaricate lobes; seeds smooth and glabrous.
Type: Chrysosplenium ramosum Maxim.
This series is monospecific one, also occurring in China, namely C. ramosum Maxim.
(2) Ser. Delavayi Hara
Disk distinctly 8-lobed, Papillae sparse, brown around the disk; ovary mostly inferior; capsule nearly truncate and emarginate at top, and bilobed with equal and horizontally divaricate lobes; seeds distinctly longitudinally 10-16-costate and transversely striate on the ridge.
Type: Chrysosplenium delavayi Franch.
This series can be considered as the most advanced one in the Chrysaspleninm L.
So far, the Chrysosplenium L. comprises 64 species in the world, among which 1 species is found in North Africa, 2 in South America, 4 in Europe, 5 in North America, 56
in Asia, of which 3 occur in Sikkim, 5 Bhutan, 5 Mongolia, 6 north Burma, 6 Korea, 7
north India, 8 Nepal, 12 Japan, 17 U.S.S.R. (of which 3 also in Europe), 34 China (including 22 endemic species and 3 new species).
In China, Fujian and Guangdong Provinces and Zhuang Autonomous Region of Guangxi each has only 1 species, Taiwan, Zhejiang, Shanxi and Hebei Provinces and Uygur Autonomous Region of Xinjiang each has 2, Anhui, Jiangxi and Hunan Provinces
each has 3, Qinghai Province 4, Heilongjiang, Liaoning and Guizhou Provinces each has
5, Jilin and Hubei Provinces each has 6, Gausu Province 8, Shaanxi Province and Xizang (Tibet) Autonomous Region each has 10, Yunnan Province has 11, Sichuan Province has 14.
Thus the distribution centre of this genus should be in the north temperate zone
of Asia, and the region covering Shaanxi Gansu, Sichuan, Yunnan and Xizang may be
regarded as an important part of this centre.
The 7 species of Ser. Nudicaula Maxim. emend. J. T. Pan can be considered as the
most primitive ones in this genus. They are mostly distributed in Shaanxi (Qin Ling),
south Gansu, southeast Qinghai, southwest Sichuan and nothwest Yunnan of China. This
region may be considered as the centre of the origin (or at least differentiation) of this
genus.
The new species and the new varieties described in this paper are as follows: C. hydrocotylifolium Levl. et Vant. var. emeiense J. T. Pan, C. taibaishanense J. T. Pan, C.
lixianense Jien ex J. T. Pan, C. qinlingense Jien ex J. T. Pan. 相似文献

本文报告了盘花垂头菊Cremanthodium discoideum Maxim.上的一锈菌新种——垂头菊柄锈菌Puccinia cremanthodii J.Y.Zhuang et S.X.Wei。模式标本采自青海省,保藏在中国科学院微生物研究所真菌标本室。本种主要特征是:冬孢子椭圆形或近倒卵形,两端圆,中部略缢缩,32—48×19—32μm,孢壁肉桂褐色至粟褐色,2—3.5μm厚,连同孔帽约5μm厚,有不规则的网状皱纹,柄达100μm长,易破碎。垂头菊属植物上未曾记载过有锈菌,本种为首次报道。垂头菊属是喜马拉雅和青藏高原的特有属,分布高海拔地带,推测此菌可能为青藏高原所特有。 相似文献

Singchia Z. J. Liu & L. J. Chen, a new orchid genus, is established based on the new species S. malipoensis Z. J. Liu & L. J. Chen found in southeast Yunnan, China. The new genus is related to Pteroceras, from which it differs by having a lip with its basal margins immovably adnate to the lower part of the pendent column foot, a thin-walled spur, and very unequally and deeply split pollinia, each with a distinct caudicle. In addition to a discussion on Ascocentrum pusillum, a species of questionable placement, another new genus, namely Gunnaria S. C. Chen ex Z. J. Liu & L. J. Chen, is set up and a new combination, namely G. pusilla (Aver.) Z. J. Liu & L. J. Chen, is made. The new genus Gunnaria differs from its allyAscocentrum by having a cross-shaped pollinarium, sulcate or split pollinia, each with a distinct caudicle attached to a common linear stipe much longer than either pollinia or viscidium, and strongly incurved side lobes of the lip. 相似文献
