the three filaments are completely united into a central terete 
column, terminated by three fleshy connectives, slightly divari- 
cating, upon each side of which the anther-cells are deeply im- 
bedded, leaving the margins of the connectives excurrent ; the 
anther-cells are globose, bursting 2-valvately by a longitudinal 
furrow along the edge of a semiseptum, which makes each bi- 
locellate : this monadelphous column is as long as the unre- 
flected portion of the sepals, the apices of which are rotately 
expanded, as in Chondrudendron.

This species, though different, is very analogous in all respects 
to that last described. Its branchlets are slender, with axils 
■|-2 inches apart ; the leaves are 2-2| inches long, lj-l§ inch 
broad, on a petiole ly-lj inch long, inserted 1^-2 lines within 
the rounded basal margin. The (^panicle is racemiform, spring- 
ing from a gemmiform tuft in the axils of the upper and younger 
leaves, is | inch long, the rachis being bare below its middle 
and furnished above with six or seven very short branchlets, 
each with one to three pedicellated flowers ^ line in diameter 
in bud; the sepals, fifteen in number, resemble those of the 
preceding species; the petals are more lanceolate, with a spathu- 
late claw ; the union of the three filaments into a central column 
does not quite reach the summit, but leaves a short terminal
