국표에 없다.

Barleria prionitis is a shrub in the family Acanthaceae, native to Island and Mainland Southeast Asia, China, the Indian Subcontinent, the Arabian Peninsula and northeastern Africa. It is widely spread as an ornamental and weed, occurring in naturalised populations around the world. It used not only as an ornamental but also as a hedge and extensively as a component of folk medicines. As a weed it is regarded as problematic in many areas.

Description

A much-branched shrub up to 1.8m tall, the lower leaf axils have spines 1–2 cm in length, one of the specific features of this Barleria. The stem and branches are terete, smooth, lenticellate and glabrous. The leaves are elliptic to ovate (4-10.5 × 1.8-5.5 cm) with both surfaces pubescent when young but becoming glabrescent soon. The large golden-yellow flowers are clustered in the axils of the upper leaves and/or on bracts. Apically spinose calyx lobes and a yellowish to orange corolla are used to distinguish this species from other Barleria. In Zhōngguó/China, flowers appear October to December, while fruiting occurs from December to February, while in Pakistan there is all year flowering. The Australian flowering and fruiting times are trimodal, from March to June, August to October and December.

The subspecies pubiflora (see Taxonomy, below) is separated from the nominate subspecies by having longer anthers (5mm or more) and corolla (4.5–7 cm) and larger leaves (up to 17 x 5.5 cm).
