Abstract:

Kengyilia Yen et J L Yang is a recently established genus in trib. Tritieeae of

Poaceae. In this paper, this genus is taxonomically revised, and a new taxonomic system is

presented. The new system includes 3 sections, 26 species and 6 varieties, of which 3 sec-

tions and 1 species are described as new, 7 taxa are treated respectively in the ways of new

status or combination and reduction. Three new sections, sect. Kengyilia, sect. Ste-

nachyra L. B. Cai and sect. Hyalolepis (Nevski) L. B. Cai, are differentiated by the

length and width of spike, the growing position of spikelet, the relative length of glume, the

colour of anther and so on. The sect. Kengyilia contains 9 species, distributed in northwest-

ern China, extending westward to Kazakhstan, Kirghizia, Tadzhikistan, Afghanistan and I-

ran; the sect. Stenachyra L. B. Cai comprises 10 species and 3 verieties, distributed in

western China, mainly in the Qinghai-Xizang Plateau; and the sect. Hyalolepis (Nevski)

L. B. Cai consists of about 7 species and 3 varieties, distributed in western China, extending

westward to Kirghizia and Tadzhikistan. Twenty-six species of Kengyilia are recognized on

the basis of the same criterion of specific concept, and the other taxa below the rank of

species are also checked in terms of their external morphology. As a result, Kengyilia pen~

dula L. B. Cai is reported as a new species; K. hirsuta var. obviaristata L. B. Cai is

raised to a species; K. melanthera (Keng) J. L. Yang, Yen et Baum is reduced to a vari-

ety under K. thoroldiana (Oliver) J. L. Yang, Yen et Baum; Roegneria hirsuta var. leio-

phylla Keng et S. L. Chen is reduced as a synonym of K. hirsuta var. hirsuta; Agropy-

ron thoroldianum var. lasciusculum Melderis is reduced to K. grandiglumis (Keng et S.

L. Chen) J. L. Yang, Yen et Baum; Roegneria rigidula var. intermedia Keng et S. L.

Chen to K. rigidula (Keng et S. L. Chen) J. L. Yang, Yen et Baum; R. hirsuta var.

variabilis Keng et S. L. Chen and R. rnelanthera var. tahopaica Keng et S. L. Chen to

K. hirsuta (Keng et S. L. Chen)J. L. Yang, Yen et Baum. In addition, new records on

the geographical distributions of some taxa are also reported in this paper.
