thus recurved upon itself when the anther comes into the 
erect position. The two species are nearly related, being 
principally distinguished by the number of the stamina, 
which are only four in the latter. 
1l. MELasTOMA FALLAX. WJ, 
M. tetrandra, paniculis terminalibus, foliis ovatis quinquenerviis 
subtus tomentosis, antheris erectis infra medium affixis. 
. Native of Sumatra. 
A shrub with long rather compressed tomentose branches. 
- Leaves opposite, petiolate, ovate, cordate at the base, acu- 
minate, four or five inches long, entire, five-nerved, smooth 
above, tomentose and ferruginous beneath.  Petioles about 
half an inch inlength. Panicles terminal, erect, many-flow- 
ered; divisions opposite. Bracts small, acute, at the base 
of the flowers, opposite. Calyx adnate to the ovary, four- 
sided, contracted at the mouth; limb spreading, almost 
entire, four-cornered. Corolla white, four-petalled ; petals 
subrotund, inserted on the calyx. Stamina four, filaments 
erect, expanded into a membrane at the summit, which is 
adnate to the anther from near their middle to their base: 
anthers thick, corrugated, nearly straight, without appen- 
dices at the base, beaked, opening by a pore at top, at- 
tached by their anterior faces to the filaments a little below 
the middle. Before flowering the anthers are doubled down- 
wards upon the filaments, so as to have the appearance of 
being pendulous; by the extrication of their beaks, how- 
ever, the upper part of the filament is reflexed, and the 
point of insertion, which before expansion was posterior, 
becomes anterior. Ovary adnate to the calyx without con- 
necting septa or cells, the beaks of the anthers not reaching
