ARACEAE 91 
reduction of Rhaphidophora huegeliana Schott. However, Rha- 
phidophora huegeliana is a distinct species=Epipremnopsis 
huegelianum Engl.; does not occur in the vicinity of Manila; 
and is a species to which Blanco’s description does not apply. 
Rhaphidophora merrillii Engl. is fairly common in the vicinity 
of Manila; is widely distributed in the Philippines at low alti- 
tudes; agrees with Blanco’s description and the indicated time as 
to flowering; and is very generally known to the Tagalog as 
tibdtib, one of the names cited by Blanco. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
January, 1915, there known as tibdtib (Merrill: Species Blan- 
' coanae No. 715). 
AMORPHOPHALLUS Blume 
Arum decurrens Blanco FI. Filip. (1837) 656 (sp. nov.) ; ed. 2 (1845) 457; 
ed. 3, 3 (1879) 62=AMORPHOPHALLUS CAMPANULATUS (Roxb.) 
Blume. 
Arum decurrens Blanco is the whole basis of Amorphophallus 
decurrens Kunth, which Engler, Pflanzenreich 48 (1911) 108, 
has admitted as a doubtful species. It is identical with A. cam- 
panulatus Blume. The species is widely distributed in the set- 
tled areas of the Philippines at low and medium altitudes, 
growing in thickets, in waste places, along roadsides, etc., but 
never in the virgin forests. The spathes and spadices are 
enormously variable in size, depending largely on the size of 
the corm, and shrink much in drying. 
Illustrative specimen from Pantay, Rizal Province, Luzon, 
June (flowers), September (leaves), 1915, there known as 
pongdpong (Merrill: Species Blancoanae No. 1044).

Calla maxima was reduced by Naves to Alocasia indica 
(Roxb.) Schott, but seems rather to be referable to A. macror- 
rhiza. It is common and widely distributed in the Philippines 
and exceedingly variable in size; when young acaulescent or 
nearly so, later with a trunk up to 4m in height. Calla badian 
Blanco is included in the second and third editions of the Flora 
de Filipinas, without specific name, casually mentioned under 
Caladium esculentum; i. e., Colocasia esculenta Schott. F.-Villar 
reduced it to Alocasia indica Schott var. variegata Engl., while
