 petioles about 3 cm long. Tendrils leaf-opposed, entire, up to 

 20 cm long. Cymes axillary and terminal, lax, up to 10 cm long, 

 peduncled. Flowers 4-merous, greenish-white, 4 mm long, the

I originally wrote the description of this species in 1904, but later 

 considered it to be the same as Cissus rostrata Korth., and so recorded it. 1 

 After an examination of the material in the Kew Herbarium, I came to the 

 conclusion that Cissus rostrata Korth., was a different species, as yet not 

 found in the Philippines, from which Cissus oblongifolia differs in its 

 broader leaves which are not rostrate-acuminate at the apex. The present 

 species is manifestly allied to Cissus re-pens Lam., but is distinguished by 

 its quite differently shaped leaves and much larger flowers.

A species found in the drier parts of the Archipelago, with the appear- 

 ance of having been introduced. It is well characterized by its stout, 

 green, very fleshy, 4-angled stems, which shrink much in drying.

This species is based on Neriam Pulli Rheede Hort. Malabar. 7: t. 48, 

 for Lamarck in his original description cites no specimen, giving only the 

 reference to Rheede cited above and a reference to Ray's Historia Plan- 

 tarum. Rheede's figure is an excellent one, but represents a plant with
