VITACEAE 

 CISSUS Linnaeus 



CISSUS ASSAM ICA (Laws.) Craib in Kew Bull. (1911) 30; Gagnep. Not. 

 Syst. 1 (1911) 353. 

 Vitis assamica Laws, in Hook. f. Fl. Brit. Ind. 1 (1875) 648. 



Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10682, 

 Levine lJt65, 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 & Am. 

 and has perhaps been included by these authors under Lamarck's species; 

 it is, however, abundantly distinct from Cissus repens Lam. 



COLUMELLA Loureiro 



COLUMELLA TEN U I FOLIA (Heyne) Merr. in Philip. Journ. Sci. 11 

 (1916) Bot. 134. 

 Cissiis tenuifolia Heyne in Wall. Cat. (1831) no. 6022; Planch, in DC.

 Cayratia tenuifolia Gagnep. in Not. Syst. 1 (1911) 348. 

 Macao, Gallery 93! Kwangtung Province, Levine 1000, originally identi- 

 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. Fl. 2 (1830) 122, are synonyms of Partlienocissus 

 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. Fl. 

 Cochinch. (1790) 272; Loureiro's name, however, is a synonym of Clausena. 

 However, as Parthenocissu^ Planch, is the retained name adopted by the
