Baia.] cvi. GESNERACE/E. (C. B. Clarke.) 365 



The generic name was by Commerson spelt originally Beaua in ms., and aftor- 

 wards simplified to Bea, also in ms. It was first published in Lamk. Diet. (1783) i. 401, 

 and spelt Bcea ; afterwards iu Juss. Gen. (1789) 121 as Ba^a. Bgea was adopted by 

 Brown, DC., and by Bentham in Gen. Plant., but Boea has priority of publication. 



1. B. prolixa, Clarke-, stem short, leaves lanceolate or ovate-lanceo- 

 late coriaceous tomeutose beneath, peduncle very long, cymes many-fld.,

 rhomboid at the base, minutely crenulate, arachnoid above ; nerves beneath obscured 

 bytomentum; petiole 1 in. Peduncle 9 in., rusty-tomentose ; cyme 2 in. diain., 

 about 50-fld., with deciduous tomentum; pedicels \ in., puberulous. Sepals }., in.,

 MOULMEIN ; Parish. DISTBIB. Cochin China. 



Stem 1-5 in. ; upwards cinnamoueous-tomentose. Leaves crowded, 6 by 2 in., 

 subobtuse, base unequally rhomboid, deciduously floccose above, ultimately nearly 

 glabrous beneath except on the much-elevated nerves ; petiole g 1 in. Peduncles 

 several, 4-7 in., floccose-tomeutose ; cyme 2-3 in. diam., up to 50-fld., tomentose. 

 Sepals T ' 2 in., sublinear. Corolla i in., puberulous without. Ooary densely covered 

 with sessile glands ; style glabrous. Capsule glandular-puberulous. In the Khasian 

 plant the nerves of the leaves beneath are thick, tomentose ; in the Burmese plant 

 they .are beneath slenderer, pubescent ; and the branches of the cyme are slenderer.

 elliptic acuminate crenate-serrate sparsely pilose on both surfaces, base 

 attenuate, cymes contracted many-fld., capsule in. Boea n. 3, Herb. Ind.
