POTHOS CELATOCAULis N. E. Br. in Gard. Chron. 13 (1880) 200; Engl, 

 in Bot. Jahrb. 25 (1898) 5, Pflanzenreich 3,7 (1908) 44. 

 This was described from Bornean material, and Engler, 1. c, referred 

 to it Warburg 14603, from Davao, Mindanao. Later, Pflanzenreich 21 

 (1905) 44, Engler admits the species as one of doubtful status from Borneo 

 only. It is probably a Rhaphidophora, R. celatocaulis v. A. v. R. in Bull.

POTHOS SCANDENS Linn. Engl. Pflanzenreich 21 (1905) 26, quoad Philip.;

177. 

 Vidal 1990 is referred here by Engler, who gives the range of the spe- 

 cies as from India to Indo-China, Java, Sumatra, and Borneo. I suspect 

 the Philippine specimen to be referable to P. hermaphroditus Merr. in 

 which species the relative length and width of the petiole and lamina are 

 exceedingly variable.
