Loh Fau Mountain (Lofaushan), Merrill 10191, on open grassy slopes, 
altitude about 500 meters. 
The oldest valid specific name for this species is here adopted. Rendle* 
enumerates this form from China as Andropogon hirtifiorus Kunth, follow- 
ing Hooker f.’ in this identification. Hooker f. states that Dr. Stapf had 
identified the Indian form with the American and African ones. In any 
case Rottboellia sanguinea Retz. is the earliest name for the species. 
DIGITARIA Heister 
DIGITARIA VIOLASCENS Link Hort. Berol. 1 (1827) 229. 
Honam Island, near Canton, Merrill 10089, on open sterile hillsides at 
low altitudes. 
In this identification I follow Hackel, as the Chinese specimens conform 
in all particulars with Philippine material so named by him. It has per- 
haps been included in Chinese lists under Digitaria longiflora Pers.

Loh Fau Mountain (Lofaushan), Merril 10270, along the margins of a 
small pool in open grass lands near the summit, altitude about 1,250 meters. 
India to tropical Africa, Malaya, and tropical Australia; not credited 
to China by Rendle in Forbes and Hemsley’s Enumeration of Chinese 
plants. 
PANICUM PALUDOSUM Roxb. FI. Ind. 1 (1820) 310. 
Honam Island, near Canton, Merrill 99U8, about water holes in muddy 
places at about sea level. 
This species has not hitherto been reported from China. Roxburgh’s 
species has been confused by many authors with Panicum proliferum Lam., 
an American species, which Hitchcock has shown to be identical with the 
older Panicum miliare Lam. It is possible that Panicum paludosum Roxb. 
may prove to be identical with the American Panicum dichotomiflorum 
Michx. 
PANICUM AURITUM Presl Rel. Haenk. 1 (1830) 305. 
Honam Island, near Canton, Merrill 98i5, about water holes, at about 
sea level. 
India to Malaya and Lie Philippines, not previously reported from China.
