Abstract

In this study the revised distribution records of 25 species of Astragalus L. in India has been provided along with correct nomenclature and taxonomic notes. In addition, the relationship, conservation status and Cibachrome photographs of the type materials for some species have also been included wherever found necessary. Based on field and herbarium studies nine species (I. E. A. alitschuri B. Fedtsch, A. charguschanus Freyn, A. contortuplicatus L., A. flemingii Ali, A. iodotropis Boiss. & Hohen, A. pyrrhotrichus Boiss., A. subumbellatus Klotz., A. stocksii Bunge, A. zacharensis Bunge) have been excluded, as they do not occur in the present political boundaries of India of 1971. Those species have also been discussed here which have been recently transferred from Astragalus to some other genera like Ophiocarpus (Bunge) Ikonn., Podolotus Benth. And Podlechiella Maassoumi & Kaz. Osaloo. The present investigation also reveals that about 12 species are not represented in Indian herbaria, while they have been recorded from India based on very old collections housed at different foreign herbaria. A new combination Caragana aegacanthoides (Parker) Chaudhary & Srivastava has been proposed based on Astragalus aegacanthoides Parker.

中文摘要

本研究提供25 種印度產紫雲英屬植物的正確地理分布、正確的學名與分類的觀察紀錄。此外也包括一些模式植物的關係、保育狀況和照片。根據田野與標本館的研究顯示，以下九種植物自從1971 年都沒有出現在印度的領土內，所以被排除 (I.e. A. alitschuri B. Fedtsch, A. charguschanus Freyn, A. contortuplicatus L., A. flemingii Ali, A. iodotropis Boiss. & Hohen, A. pyrrhotrichus Boiss., A. subumbellatus Klotz., A. stocksii Bunge, A. zacharensis Bunge)。一些植物雖然最近從紫雲英屬被轉移到其他屬中 (Ophiocarpus、Podolotus、Podlechiella) 也被納入討論。本研究也顯示，約有12 種被收藏在不同的國外標本館，然而在印度的標本館卻沒有被紀錄到。依據Astragalus aegacanthoides Parker 提出一個新組合 Caragana aegacanthoides (Parker) Chaudhary & Srivastava。
