arranged on the primary branches, 5-merous, yellow. Calyx 
shallow, about 1.3 mm in diameter, 0.5 mm high, obscurely 
denticulate. Petals 5, free, narrowly oblong, about 3 mm long, 
1 mm wide, glabrous. Stamens alternating with the petals ; 
filaments 1 mm long ; anthers ovoid, as long as the filaments. 
Rudimentary ovary oblong-ovoid, hirsute, 0.7 mm long. 
Leyte, Buenavista, near Jaro, C. A. Wenzel 987, July 16, 1914, in forests, 
altitude about 500 meters. 
The first representative of the genus to be found in the Philippines and 
allied to Sarcostigma wallichii Baill., differing, however, in many characters, 
the leaves entirely glabrous not pubescent beneath, petioles much longer, 
and nerves fewer; the male inflorescence is entirely different, consisting 
of lax panicles up to 40 cm in length, not of simple spikes. 
BEGONIACEAE 
BEGONIA Linnaeus 
BEGONIA WEN2ELII nom. nov. 
Begonia leytensis Merr. in Philip. Journ. Sci. 9 (1914) Bot. 379, non 
Elm. 
Begonia leytensis Elm. is a synonym of Begonia quercifolia A. DC. [see 
Merrill in Philip. Journ. Sci. 7 (1911) Bot. 311], and the previous use of 
this name was inadvertently overlooked by me when characterizing B. 
leytensis Merr. I accordingly propose the above new name for the form 
described by me as Begonia leytensis.
