Lens montbretii has a diploid chromosome number of In – 12 whereas the remainder of the genus has 2n= 14. In addition there are marked karyotype differences. These, combined with morphological characteristics which distinguish it from other species of Lens , are considered to be an adequate basis for the returning of the taxon to the genus Vicia as V. montbretii Fisch. & Mey. 相似文献

AbstractChains of 3–4-celled gemmae have been observed on the protonema of Trematodon brevicalyx, both in nature as well as in cultures. They are produced in abundance and may help in its survival, propagation and wide dispersal. 相似文献

AbstractThe marked differences between Plagiochila spinulosa (Dicks.) Dum. and P. killarniensis Pears. pointed out by Paton (1977) are confirmed and added to by further ones. As a result the two species are placed in different sections Spinulosae and Zonatae, respectively. For each of the two species the full synonymy including new synonyms and new lectotypifications and a comprehensive list of studied specimens and a distribution map are presented. In appendix, P. porelloides (Torrey ex Nees) Lindenb. is recorded from Madeira, a species new to Macaronesia. 相似文献

AbstractThe results of a comparative study of Pohlia muyldermansii from Continental Europe and the British Isles are presented. Two varieties are recognized, var. muyldermansii from Belgium and the Netherlands and var. pseudomuyldermansii var. nov. from Great Britain, Ireland, Austria and Switzerland. P. camptotrachela is reported from Belgium and differences between this species and P. muyldermansii discussed. 相似文献

The first phytochemical investigation on the aerial parts of Fumana procumbens (Dunal) Gren. & Godr. led to the isolation and identification of six compounds, including two biflavonoids, i.e. dihydrodaphnodorin B (1) and daphnodorin B (2); three flavonoids, i.e. quercitrin (3), myricitrin (4), and quercetin (5); and a flavan derivative, i.e. epigallocatechin (6). The structures of the compounds were elucidated by extensive 1D- and 2D-NMR spectroscopic analysis in combination with MS experiments. This is the first report on the isolation of biflavonoids from the genus Fumana and from the family Cistaceae. 相似文献

Two rare and ill-known subtidal species of stalked, net-forming green algae, Struvea gardineri A.Gepp & E.Gepp and Phyllodictyon orientale (A.Gepp & E.Gepp) Kraft & M.J.Wynne, are re-described on the basis of the examination of type material and recent collections from the Maldives, Seychelles, and Socotra Island in the tropical Indian Ocean. The taxonomic position of both species is re-appraised on the basis of morphological data (cell division, branching pattern, tenacular cells, crystalline cell inclusions, cell shape, and cell dimensions) and molecular phylogenetic evidence (partial large subunit nuclear ribosomal DNA sequences). On the basis of the occurrence of segregative cell division in young plants of S. gardineri , this species is returned to its original genus, Struvea . Cell division in P. orientale takes place exclusively by centripetal wall ingrowths, confirming its placement in the genus Phyllodictyon as currently defined. However, morphological observations and molecular phylogenetic studies indicate that the delineation of genera on the basis of modes of cell division is problematic, and that the genera Struvea and Phyllodictyon , as presently conceived, almost certainly do not represent natural groups. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 153 , 115–132. 相似文献
