Abstract:

Our observations on characters of leaf epidermis, lemma, palea etc. in the genera

Acroceras Stapf (many species), Neohusnotia tonkinensis (Balansa) A. Camus (the type of

Neohusnotia), Setiacis diffusa (Chia) S. L. Chen & Y. X. Jin (the type of Setiacis), Lasiacis

divaricata (L.) Hitchc. (the type of Lasiacis^[4]) and Psilochloa pilgerana (Schweick.) Launert

(the type of Psilochloa^[4]) in Subtribe Paspalinae^[1] Keng& Keng f. show that Setiacis diffusa

differs from the others by several characters, which merits establishing a new genus—Setiacis

S. L. Chen & Y. X. Jin in this subtribe^[1]. The Latin description of the new genus is given

in this paper.

Key words: Acroceras, Neohusnotia, Setiacis, Lasiacis, Psilochloa
