B. bombycma, Bl, (Ennm. PI. Jav. 97) is possibly identical with this; it has 

 been reduced here by De Candolle and part of it is no doubt so reducible. Under 

 B. homhycina however have been distributed specimens of an allied species with 

 larger flowers in short spreading cymes. Which of the two plants Blume intended 

 as his B. homhycina, it is impossible from his short description and in the absence of 

 authentic specimens to determine. 



3. Begonia isopteroidea, King n. sp. Caulescent, 3 feet high, 

 glabrous. Zfert?;e5 thin, very obliquely ovate-lanceolate acuminate; the 

 base acute on one side of the petiole but with a broad round auricle 

 on the other, the edges remotely lobulate-dentate ; lower surface with 

 very minute white scales ; main-nerves 7, radiating from the base, 

 rather prominent beneath; length 3*5 to 45 in.; breadth 1*2 to J '5 in. ; 

 petioles unequal, 2 to 3-5 in long. Stipules broadly lanceolate, acute, '5 

 to '75 in. long. Peduncles slender, axillary, about an inch long and 

 bearing about two flowers on long slender pedicels and one sub-sessile. 

 Flowers pink, large. Males; sepals 2, rotund-oblong, blunt, '75 in. 

 long ; petals 2 similar but only '5 in. long ; stamens inserted on an 

 elongate anthophore, the anthers quadrate, 2-groved, truncate, only 

 about half as long as the slender filaments. Females nearly as large as 

 the males; style short, thick, divided into 3 slender, bifid spiral spread- 

 ing branches. Gapsnles about '75 in. in length and breadth, 3-celled, 

 its wings narrow oblong, thin, membranous, the posterior narrower than 

 the lateral. 



Perak; on Gunong Brumban, elevation 5,000 feet; Wray 1548. 



A species in leaves capsules and habit resembling B. isoptera, but with much 

 larger flowers. 



4. Begonia sinuata. Wall. Cat. 3G80. Shortly caulescent (from 

 25 to 12 inches high) the rootstock tuberous. Leaves either broadly
