摘要

Aeschynanthus maoi 是产自印度阿鲁纳恰尔邦下迪邦山谷的一种 Gesneriaceae 新种，本报告对其进行了描述并绘制了插图。wardii 和 A. bracteatus 相似，但与前者的区别在于苞片小（3-5 毫米长），萼裂片狭卵形或三角形，花序 1-8 朵花，退化雄蕊陀螺状。它与后者的不同之处在于早落的绿色苞片、短花序梗（0.2-0.8 厘米长）以及狭卵形或三角形的绿色萼裂片。本文提供了新物种的详细描述、彩色照片以及与类似物种的比较。根据世界自然保护联盟（IUCN）红色名录的类别和标准，对该新物种的灭绝风险进行了评估，并将其暂定为极危物种（CR）。

Aeschynanthus maoi, a new species of Gesneriaceae from Arunachal Pradesh, India

Aeschynanthus maoi, a new species of Gesneriaceae from Lower Dibang Valley of Arunachal Pradesh, India, is described and illustrated. It is morphologically similar to A. wardii and A. bracteatus, but differs from the former by its small (3–5 mm long) boat-like bracts, narrowly ovate or triangular calyx lobes, 1–8 flowered inflorescences, and turbinate staminodes. It differs from the latter by caducous green bracts, short peduncles (0.2–0.8 cm long), and narrowly ovate or triangular green calyx lobes. A detailed description of the new species with color photographs and a comparison to similar species are provided. The new species is evaluated for risk of extinction and provisionally assessed as Critically Endangered (CR) according to IUCN Red List Categories and Criteria.

期刊介绍： Since 1931, Brittonia, assuming the broadest possible definition of the field of systematic botany, has been an important outlet for the publication of original research articles on anatomy, botanical history, chemotaxonomy, morphology, paleobotany, phylogenetic systematics, taxonomy, and phytogeography. Each issue contains articles by the staff of The New York Botanical Garden and outside contributors, book reviews, and announcements.
