RUMPHIUS'S HERBARIUM AMBOINENSE 



represent Cissus trilobata Lam., which is a true Cissus and is 

 known only from India. Miquel, Fl. Ind. Bat. 1 2 (1859) 602, 

 placed it under Cissus cinerea Lam., which is apparently merely 

 a pubescent form of Columella trifolia (Linn.) Merr., and 

 in Ann. Mus. Bot. Lugd.-Bat. 1 (1863) 81 placed it, with 

 doubt, under Vitis geniculata (Blume) Miq. = Columella genicu- 

 lata Merr., a species that it certainly does not represent. The 

 form described by Rumphius as Folium causonis II rubrum is 

 apparently merely a color variant of Columella trifolia (Linn.) 

 Merr., although Hasskarl, Neue Schlussel (1866) 145, thought 

 that it might be Vitis geniculata Miq. 



Columella Lour., Fl. Cochinch. (1790) 85, has been accepted 

 by me as the proper generic name for this group, although the 

 recognition of it invalidates Columellia Ruiz & Pavon (1794) 

 of the Columelliaceae. I am of the opinion that Gagnepain * 

 was justified in segregating from Cissus as a distinct genus, 

 those forms placed by Planchon in the subgenus Cayratia, dif- 

 fering from him only in the selection of the generic name. 



TETRASTIGMA Planchon

Folium causonis ill litoreum Rumph. Herb. Amb. 5: 450. 



No Tetrastigma occurs in our Amboina collections, yet from 

 the description given by Rumphius, I have little doubt that 

 the form described as Folium causonis III litoreum is referable 

 to this genus. Hasskarl, Neue Schlussel (1866) 145, thought 

 that it might be referable to Vitis geniculata Miq. var. grosse- 

 serrata Miq.

Burman f., Fl. Ind. (1768) 78, erroneously placed this under 

 Aralia chinensis Linn. Willdenow, Sp. PI. 1 2 (1797) 1177, re- 

 ferred it to Leea sambucina Willd., in which he was followed by 

 numerous authors, Persoon, Roxburgh, Roemer and Schultes, Don, 

 Dietrich, and others. Miquel, Ann. Mus. Bot. Lugd. Bat. 1 

 (1863) 98, reduced it to Leea aequata Linn., which is certainly 

 the correct disposition of Frutex aquosus femina Rumph. The 

 figure is poor, and from it alone it would be difficult to determine
