666 Lxvi. BEGONUCE^. (0. B. Clarke.) ^Begonia. 



Vab. 3. malabarica; leaves glabrous, capsules large slightly subqnadral rather 

 than elliptic. — ^As to Sheede Hart. Mai. ix. t. 86 referred here, it may be the present 

 plant as it is difficult to guess what other species Bheede could have got in Malabar : 

 though it differs not merely in the points mentioned by Alph. DC. ; but in the male 

 flowers with two sepals and two petals.

B. TEiroiFOLiA, Drt/and, in Trans. Linn. Soc. i. 162, from Pulo Pontangh, is not 

 a Fulo Hnang plant as A. DC. suspects from the similarity of the names (see Frodr.
