VITACEAE 
CISSUS Linnaeus 
CISSUS ASSAM ICA (Laws.) Craib in Rew Bull. (1911) 30; Gagnep. Not. 
Syst. 1 (1911) 353. 
Vitis assamica Laws, in Hook. f. FI. Brit. Ind. 1 (1875) 648. 
Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10682, 
Levine 14-65, August 17, 1917, in thickets, damp ravines, altitude about 900 
meters. 
This species extends from India (Assam and Sikkim) to Siam, but has 
not previously been reported from China. It is very similar to Cissus 
adnata Roxb., but is easily distinguished, among other characters, by its 
more or less appressed hairs being attached by the middle, not by the base. 
The Chinese specimens cited above have distinctly pubescent inflorescences, 
but the leaves are practically glabrous, except for a few scattered hairs 
on the lower surface; the disk and ovary are entirely glabrous. By the 
key given by Dunn & Tutcher this falls under Vitis repens Wight & Arm 
and has perhaps been included by these authors under Lamarck’s species; 
it is, however, abundantly distinct from Cissus repens Lam.

fied by me as Columella japonica. Formosa, Arisan, Faurie 512, June, 1914. 
This has been included in Cissus japonica Willd., but is certainly specific- 
ally distinct. India to southern China and the Philippines.

Japan to Indo-China; the Philippine specimen referred by Gagnepain to 
this species I consider to represent Columella corniculata (Benth.) Merr. 
PARTHENOCISSUS Planchon 
It has been conclusively shown that Psedera Neck. Elem. 1 (1790) 158, 
and Quinaria Rafin. Medic. FI. 2 (1830) 122, are synonyms of Partheno cissus 
Planch, in DC. Monog. Phan. 5 (1889) 447, and that following strictly the 
rules of priority Psedera Neck, is the oldest generic name for this group. 
Quinaria of Rafinesque is preoccupied by the different Quinaria Lour. FI. 
Cochinch. (1790) 272; Loureiro ’s name, however, is a synonym of Clausena. 
However, as Parthenocissus Planch, is the retained name adopted by the
