VoL 3 CONVULVULACEAE 357 



Stephanotis mucronata (Blanco) Merr. Sp. Blancoanae (1918) 316. 

 Apocynum mucronatum Blanco Fl. Filip. (1837) 825, ed. 2 (1845) 143, 

 ■ ed. 3, 1 (1877) 259. 



Stephanotis chinensis Champ, ex Benth. in Hook. Journ. Bot. Kew 

 Miscel. 5 (1853) 53. 

 Blanco's description was based on specimens grown from Chinese seeds; 

 the species apparently no longer occurs in the Philippines, cultivated or 

 otherwise. 



Vincetoxicum sp.; Ceron Cat. PL Herb. Manila (1912) 117; Usteri Beitr. 

 Ken. Philip. Veg. (1905) 121. 



Ceron's record is based on Vidal 3281, 3311, 3303, from Luzon; I suspect 

 that the generic identification is wrong. 



Cylixylon heterophyllum Llanos Frag. PL Filip. (1851) 59; F.-Vill. 

 & Naves in Blanco FL Filip. ed. 3, 4 1 (1880) 42; Merr. Sp. Blan- 

 coanae (1918) 320. 

 I have been unable definitely to place this genus and species as described 

 by Llanos from his very imperfect description; the type is not extant. It 

 can scarcely be Gymnanthera pedunculated (Miq.) F.-Vill. where F.-Villar 

 placed it.
