166 DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 
longi. Flos masculus: Sepala alba, rotunda, vix 2 lin. dimetientia. Petala nulla; 
filamenta basi connata brevissima; anthere obovato-cuneate, obtuss, vix 3 lin. 
longe. Capsula (ex icone) obovato-oblonga, ultra-pollicaris, trialata, alis equalibus, 
2 lin. longis. 
Near the Dahombang River, alt. 3000 feet (Haviland, 1308). 
Very like Begonia lepida, Blume, in general habit, but easily distinguished by the 
profuse inflorescence and the small apetal flowers. The latter character brings it to the 
section Petermannia, which is separable only artificially from $ Bracteibegonia. 
BEGONIA BORNEENSIS, A.DC., Prodr. xv. part i. 320 ($ Petermannia). 
At 6000 feet (Haviland, 1189). : 
Distribution: Borneo. 
There is no description of the male flowers in De Candolle's * Prodromus.' "Therefore 
I give it here :— 
Inflorescentia inascula terminalis, interdum ex folii summi axillà altera addita, panicu- 
lata, ramulis gracilibus, longe racemosis, ad 14 poll. longis, bracteatis; bracteze 
oblongz, caducze, 13 lin. longe vel minores, membranacex. Sepala alba, ovata vel 
oblonga, 14 lin. longa. Petala nulla. Antherze in toro elongato subsessiles, obovate, 
3 lin. longe. 
The female inflorescence is axillary, from the axil of the uppermost leaf. It is reduced 
to a short peduncle with two pedicels about 9 lin. long. In its place there is in one of 
the Kinabalu specimens a male inflorescence. The capsules of the type are a little 
longer and their pedicels shorter, but the difference does not seem to me sufficient to 
make the Kinabalu plant a variety.
