Аннотация. Вид Ainsliaea fulvipes Jeffrey et W.W. Sm. (Asteraceae), ранее считавшийся эндемиком Китая, здесь впервые приводится из Земитанга, штат Аруначал-Прадеш (Индия). Подробные описания, а также фотографии местообитаний представлены для облегчения идентификации.
Introduction
The genus Ainsliaea DC. comprises ca. 53 taxa, and its native range is Afghanistan to Temp. E. Asia and W. and Central Malesia (POWO, 2022). All the
taxa of the Ainsliaea are characterized by perennial herb; leaves rosulate, usually arranged at the middle of the stem; capitula few-flowered, arranged in spikes or panicles; flowers slightly zygomorphic; corolla deeply 5-lobed with unilateral lobes (Freire, 2007).

The genus Ainsliaea is allied to Macroclinidium Maxim., Myripnois Bunge, and Pertya Sch. Bip., but it can be easily distinguished by the presence of plumose pappus instead of scabrid pappus, which are found in the latter three genera (Freire, 2007). In India, five species viz. A. angustifolia Hook. f. et Thomson ex C. B. Clarke, A. aptera DC., A. apteroides (C. C. Chang) Y. C. Tseng, A. latifolia (D. Don) Sch. Bip., and A. spicata Vaniot are known to occur in the Himalayan region (Hooker, 1981; Rao, 1995; Freire, 2007; BSI, 2022).
During a botanical exploration tour to Zemithang, Tawang district of Arunachal Pradesh, an interesting plant was collected from sub-alpine forest floor near a small water reservoir. After consultation of authentic literature (Freire, 2002, 2007; Gao et al., 2011), critical examination of live specimens and herbarium specimens housed at CAL, ARUN, ASSAM and images from herbaria such as K and S, it was identified as Ainsliaea fulvipes Jeffrey et W. W. Sm., hitherto not reported from India (Rao, 1995; Chowdhery et al., 1996; BSI, 2022).
The species Ainsliaea fulvipes is considered to be endemic to the China (POWO, 2022), which is allied to A. angustata C. C. Chang. Both the species
have basal rosettes leaves with long densely strigose petiole. However, A. fulvipes can be easily segregated by its oblong to elliptic leaf blades with obtuse to rounded apex, pilose phyllaries and rounded anther appendages, whereas A. angustata is characterized by linear to elliptic lamina with acute apex, glabrous phyllaries and acuminate anther appendages (Freire, 2007). The present collections from Arunachal Pradesh confirm its extended distribution in India. The species is enumerated here with a detailed description, field photographs, and image of the voucher herbarium specimen. A key based on the diagnostic characters of all the Indian species are also given here for easy understanding.
Material and methods
The photographs of habit were taken using Nikon-Coolpix B700 digital camera. The dissected floral parts were examined under Olympus stereozoom microscope SZ-61. The herbarium was prepared as per the standard method and the voucher specimen was deposited at Botanical Survey of India, Central National Herbarium, Howrah.
