Intermediate HyalolaenaStatus: VU. Endemic. One of three species growing in Kyrgyzstan.
Description. Perennial monocarpic plant. Roots are weakly thickened, cord-like, branching. The stem is solitary, repeatedly branching. Basal leaves are lanceolate in shape, 4-6 cm long, with lanceolate, sharp terminal lobes; middle stem leaves have narrower and longer terminal lobes; upper leaves are in the form of lanceolate sharp sheaths. Umbels are 6-11 ray with a wrapper of 5-8 lanceolate, short-hairy leaves with white margins; umbellules are 11-18 flowered with a wrapper of 7-10 leaves. Petals are white. Fruits are dark brown, oval or oval-elongated.

Orthoboylu HyalolaenaIntermediate Hyalolaena
Hyalolaena intermedia M. Pimenov et KljuykovStatus: VU. It is a rare species endemic to Kyrgyzstan, one of three congeners distributed in the Republic. This perennial monocarpous plant is gypsophilous and populates limestone denudations in the Chatkal and Fergana Mountain Ranges and in the valleys of the Naryn and Bekechal Rivers, in small separated groups. Period of flowering: May - June, fruiting in June - July. Propagation is presumably generative (by seeds) only. The number is insignificant, limiting factors are not revealed, and data on cultivation are absent. Several populations are protected by common routine in the Bash-Aral Nature Reserve. The arrangement of habitat conservation for other populations is recommended to conserve the species.
