credited the species to Luzon on the basis of Cuming 513 from Laguna 

 Province. Blume's original description, however, as well as Planchon's 

 later one, is incomplete and unsatisfactory. The specimens cited above 

 appear to fall under Cayratia geniculata as keyed out by Gagnepain, and 

 are apparently close to the form designated by Blume as the variety 

 mollis. 



Doctor Gagnepain credits to the Philippines the closely allied Cayratia 

 mollissima Gagnep. (Cissus mollissima Planch.), the references being to 

 specimens collected by Baume, near Manila, and by Perrottet, from Zam- 

 boanga, Mindanao. I have seen no Philippine material that I consider 

 referable to this species, and I suspect that flowering specimens of the 

 form I have referred to Columella geniculata may match the Philippine 

 material referred by Gagnepain to Cayratia mollissima. The latter species 

 is distinguished by its large fruits and large seeds, and I have no Phil- 

 ippine material that agrees with the species, as described, in these 

 characters. In fruit and seed characters the material cited above agrees 

 with Columella geniculata, not with Cayratia mollissima Gagnep. 



Var. SARCOCARPA var. nov. 



A species diff ert subtus foliis ad costa ramulis petiolisque parce 

 ciliatis haud molliter pubescentibus, foliolis lateralibus basi 

 rotundatis vel obtusis vix cordatis vel subcordatis nervis reticu- 

 lisque prominentibus.

This form may ultimately prove to be worthy of specific rank, but as 

 there is some doubt in my mind as to the correctness of my present inter- 

 pretation of Columella geniculata, I have considered it expedient to indicate 

 the present form merely as a variety. In aspect, pubescence, the much 

 more prominent veins and reticulations, and somewhat in the shape of its 

 leaflets it is decidedly different from the form I have referred to Columella 

 geniculata, although in floral characters it closely approaches that species. 

 The fruits when fresh are soft, fleshy, somewhat watery, pink, globose, 

 and about 1.5 cm in diameter, shrinking much in drying. It occurs in 

 thickets and in forests along streams at low altitudes.
