Boa.] CVI. GESNERACEX. (C. D. Clarke.) 365 
The generic name was by Commerson spelt originally Beaua in ms., and after- 
wards simplified to Bea, also in ms. It was first published in Lamk. Dict. (1783) i. 401, 
and spelt Baa ; afterwards in Juss. Gen. (1789) 121 as Baa. Bea was adopted by 
Brown, DC., and by Bentham in Gen. Plant., but Boa has priority of publication.

late coriaceous tomentose beneath, peduncle very long, cymes many-fid., 
capsule 4 in. 
Prev ; at Thoungyun, Kurz. 
Stem 23 in., closely tomentose. Leaves opposite, crowded, 4 by 2-11 in., acute, 
rhomboid at the base, minutely crenulate, arachnoid above ; nerves beneath obscured 
by tomentum; petiole lin. Peduncle 9 in., rusty-tomentose; cyme 24 in. diam., 
about 50-fld., with deciduous tomentum; pedicels } in., puberulous. Sepals y, in., 
linear, nearly glabrous. Corolla not seen. Capsule glabrous. 
2. B. multiflora, Br. in Benn. Pi. Jav. Rar. 120; stem short, leaves 
narrowly elliptic regularly crenate mature glabrate above villous or lanate 
on the reticulated nerves beneath, cymes many-fld., capsule 4 in. A. DC.

Stem 1-5 in.; upwards cinnamoneous-tomentose. Leaves crowded, 6 by 2j in., 
subobtuse, base unequally rhomboid, deciduously floccose above, ultimately nearly 
glabrous beneath except on the much-elevated nerves; petiole 4-1 in. Peduncles 
several, 4—7 in., floccose-tomentose ; cyme 2-3 in. diam., up to 50-fld., tomentose. 
Sepals 7, in., sublinear. Corolla } in., puberulous without. Ovary 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.

diam., green, viscidly hairy. Sepals 45 in., narrowly oblong, viscidly hairy. Corolla 
iin. glabrous. Ovary glistening with yellow glands; style glabrous upwards. 
Capsule glandular-viscous, closely reflexed in young fruit. — Excessively variable in
