GRAMINEAE 
ANDROPOGON Linnaeus 
ANDROPOGON CHINENSE (Nees) comb. nov. 
Homoeatherum chinense Nees in Hook. & Arn. Bot. Beechy’s Voy. 
(1841) 239; Steud. Syn. (1854) 412. 
Andropogon apricus Trin. var chinensis Hack, in DC. Monog. Phan. 
6 (1889) 457. 
Loh Fau Mountain (Lofaushan), Merrill 10306, on open grassy slopes, 
altitude about 600 meters. 
The type of Homoeatherum chinense Nees was from Macao or its im- 
mediate vicinity, and the specimen cited above agrees closely with the 
description as repeated by Steudel. Hooker f.‘ considered that Homoea- 
therum chinense Nees, which Hackel included under Andropogon apricus, 
was the same as Andropogon fastigiatus Sw., in which disposition of it he 
was followed by Rendle, who, however, states that he had seen no specimen 
of the Chinese form. On account of its paired spikes I do not see how it 
can possibly be placed with Swartz’s species, the only one in the subgenus 
Diectomis; and again, on account of prominently bisetose first glume of the 
sessile spikelet, I do not see how it can be placed under Andropogon apricus 
Trin., although I consider it to belong in the subgenus Arthrolepis. The 
pedicelled spikelets in our material are much smaller than in American 
specimens of Andropogon fastigiatus Sw. and differ from those of Swartz’s 
species in many details.
