weak, more or less decumbent below, showing a tendency to branch at 
the nodes. The panicles are lax, with widely spreading branches. The 
spikelets are about 8 mm long, and fall very easily; while the very slender, 
stiff, straight awns attain a length of 7 cm. No awned rice was observed 
in, cultivation in the vicinity of Canton, but long-awned varieties are in 
common cultivation in northern Luzon. It might be mentioned in passing 
that no wild form of Oryza sativa Linn. has ever been found in the Philip- 
pings, although at least two distinct indigenous species occur in the Archi- 
pelago. The discovery of this wild form of the rice plant in southern China 
confirms de Candolle’s opinion that rice is a native plant in China. This 
form has undoubtedly yielded, by selection and improvement, the various 
forms of rice now so extensively cultivated in southern China, the selection 
and improvement following the lines of strictly erect habit, unbranched 
culms, elimination of the awns, and persistence of the spikelets at maturity.

Osbeck observed this species in the neighborhood of Canton and at 
Whampoa, so that the specimen cited above is practically a topotype. It 
agrees entirely with the very brief description and is the only species of 
Clematis observed by me in my exploration of the country about Canton. 
Unfortunately, the specimen presents no flowers so that I cannot be sure as 
to which of the species enumerated by Dunn and Tutcher from Kwantung it 
pertains, although I suspect it to be Clematis benthamiana Hemsl. In my
