菊科一新属,管花蒲公英属和菊科舌状花亚科的补充记载 总被引:4,自引:1,他引:4
基于菊科原萍公英属管花萍公英(Taraxacum siphonathum S.D.Sun Xuc-jum Gc,Jirshncr ct Stipanck)头状花序含两性狭窄管状花的特点,与原萍公英属有较大的判别,因而将其分出,另立一新属,管花蒲公英属(Neo-Taraxacum Y.R.Ling et S.D.sun),含管花蒲公英[NeoTaraxacum siphonathum(S.D.Sun,Xue-jun Ge,Jirshner et Stipanek)Y.R.Ling et S.D.Sun]一种。另外对菊科原舌状花亚科(Subfam.Liguliflorae)作补充订正,即除大部分属种的头状花序含两性舌状花外,补充个别属的头状花序含两性狭窄管状花。 相似文献

DRANSFIELD, J. & MOGEA, J. P., 1984. The flowering behaviour of Arenga (Palmae: Caryotoideae). The palm genus Armga , with 21 species, displays remarkable variation in flowering behaviour, involving both pleonanthy and hapaxanthy with basipetal production of inflorescences; inflorescences may be bisexual or unisexual, solitary or multiple. The ecological significance of the variation remains obscure and it is still not possible to indicate whether or not Arenga is primitively hapaxanthic. 相似文献

Comparative floral structure and systematics in the Asian palm genus Rhapis (Arecaceae,Coryphoideae)
A comparative study of the floral structure in the species of the genus Rhapis (Arecaceae, Coryphoideae, Rhapidinae) is presented. Flowers are mainly unisexual, with three sepals, three petals, 6 stamens or staminodes and three carpels or carpellodes. Some evidences of basal congenital and apical postgenital fusion of the carpels, first time reported in the genus, were observed in the gynoecium. Ovules are basally attached and crassinucellate; they appear to be slightly anatropous. The morphology of the filaments suggests a division of the species into two groups: Rhapis excelsa and R. subtilis exhibit thick and keeled filaments, whereas R. gracilis, R. humilis, R. laosensis, R. micrantha and R. multifida have slender, non-keeled filaments. Relationships of Rhapis with the rest of the genera of Rhapidinae are inferred on the light of floral structure. 相似文献

The family Heteroderidae, its two subfamilies Heteroderinae and Meloidogyninae and the nominal genera of Heteroderinae (Heterodera Schmidt, 1871; Meloidodera Chitwood, Hannon &Esser, 1956; and Cryphodera Colbran, 1966) are rediagnosed. Meloidoderita Pogosyan, 1966 is considered a genus inquirenda. Two new genera from southern California are described in the subfamily Heteroderinae. A key to the genera, illustrations and a phylogeny of the Heteroderinae are proposed. 相似文献

通过调查,对Livistona chinensis的后选模式、L.fengkaiensis和L.jenkinsiana的主模式、L.saribus的等新模式、L.speciosa的等模式与《Flora of China》中的上述种类作比较,证实《Flora of China》中的L.jenkinsiana是L.speciosa Kurz,后者被中国分类学文献(如《海南植物志》、《中国植物志》、《福建植物志》、《云南植物志》)误定为L.saribus。L.speciosa的果倒卵形、椭圆形或卵形,而L.jenkinsiana的果肾形或近球形。源于《中国植物志》的L.saribus并非原产于中国。在中国,L.speciosa原产于云南、广东、海南和福建,L.chinensis原产于广东和台湾,而L.jenkinsiana和L.saribus仅被引种至中国的植物园。 相似文献

Phenology, inflorescence behavior, and pollination of 10 sympatric taxa ofBactris were studied in a lowland Amazon forest. Taxa flowered over an eight month period during the rainy season and early dry season,
but individual taxa flowered for one to a few months. Related taxa had mostly non-overlapping flowering periods. Inflorescence
behavior was similar for all taxa, with nocturnal pistillate anthesis and temperature elevation, followed 24 hours later by
rapid, nocturnal staminate anthesis. Pollinators of all taxa were small weevilsPhyllotrox (Curculionidae) and nitidulidsColopterus (Nitidulidae), although various other insect visitors were recorded. Large numbers ofPhyllotrox were recorded on inflorescences, but weevil sex ratios were highly skewed. 相似文献

The inflorescence in all species of Salacca is enclosed in a chamber within the leaf base and is exserted through a slit on the abaxial surface of the leaf base. The inflorescence bud is interpreted ds an axillary meristem that becomes radially displaced by adaxial growth of the leaf primordium. A fine channel is produced from the leaf axil to the base of the inflorescence and persists at maturity. The channel and the bud chamber enlarge as the leaf elongates. They are lined by an epidermal layer. There is no cellular breakdown until the collapse and tearing of tissues of the leaf during inflorescence enlargement late in ontogeny. The vegetative bud is positioned about 1300 from the axil of its subtending leaf and lies directly below the abaxial inflorescence slit of the leaf above. Vegetative bud development was not observed, hut there is a suggestion of relatively late initiation. The separation of. Eleiodoxa from Salacca is supported by differences in the development of inflorescence and vegetative buds. 相似文献
