摘 要 ：Section Fibrillosa Ching contains about 25 species which is mainly distribu-ted in the Himalayan regions. Some species are doubtless splited up after the upheaval of the Himalayas，they are the endemic species to the Himalayan regions and the taxonomical characteristics between them are very close to each other, so it brings about difficultes to the classification of the section.
