in the form of its six petals, and in having only three stamens, 
whose filaments are united into a central column, leaving the 
anthers almost sessile on its furcated summit* ; the two cells of 
each anther are laterally imbedded in the nearly obsolete points 
of the filaments, the intermediate connective being very shortly 
and obtusely excurrent beyond their apex ; and they burst by a 
longitudinal suture corresponding with a narrow semiseptum, 
which renders them 2-loceilate. We may perceive in the above 
peculiar characters some analogy towards Parabcena and Syrrho- 
nema, from which genera it diSers in many respects. 
I have here described two species, one of which Dr. Eichler 
has made a third species of his genus Sychnosepalum •, but I 
have shown, under my description of the latter genus, how much 
dissimilarity exists between them : it differs in its habit, its sub- 
peltate leaves, its inflorescence and the structure of its flowers. 
The Somphoxylon of the same botanist is at variance with De- 
tandra only in its more expanded panicle, minute flowers, and 
the smaller number of its sepals (frequently an inconstant 
character) ; it agrees in the number, shape, and relative size of 
the petals, and exactly in its three monadelphous stamens. 
The species of Detandra have somewhat oval, subpeltate, 
coriaceous, 5-nerved leaves, which are glabrous and polished 
above, pale and tomentose beneath, on rather slender petioles : 
the inflorescence is a panicle shorter than the petiole, with short 
alternate branches, each bearing one to three alternate pedi- 
cellated flowers ; the flower has fifteen to eighteen closely 
imbricated sepals becoming gradually smaller externally (the 
upper moiety of the six interior and larger ones expanding 
horizontally, as in Chondrodendron) , six petals in two series, 
which are oblong or lanceolate, unguiculated at the base, and 
entire or denticulated on the margin ; the stamens are already 
described. 
Detandra, nob. — Flores dioici. Masc. Sepala 14-17, in or- 
dine ternario ad torum subcylindricum imbricatim disposita,
