The vexillary petal, innermost in the bud, is the smallest and 
the most modified. set at a somewhat higher level than the

filaments which arch over the pistil posteriorly, forming a canopy. 
he second pair of stamens, proceeding backwards, are barren, 
but their empty anthers are larger and longer than those of the other 
infertile ones. The filaments are short and cylindrical. The third 
pair have filaments broadened out into a lanceolate lamina. They 
are tipped by triangular barren anthers, as finials. The last pair

ception of the anterior stamen all the filaments carry a brush of 
purple hairs at their bases and confined to the inner face, so 
forming an almost continuous fringe around the edge of the 
the middle line, is the posterior stamen, capped by a triangular 
barren anther. Its filament is sharply bent below, the curve 
following that of the vexillary petal. The anterior stamen, carrying 
a deltoidal barren anther, has a broad, spathulate filament. It is 
shut out from the cup of the receptacle by the gyneceum, and 
carries no brush. 
The receptacular cup is well defined. Its walls are dry, 
smooth, and glistening. A cushion-like prominence occupies part 
f the floor. This cushion leans towards the pistil, a feature 
which is accentuated in the long-styled forms, where it is pro- 
longed into a tongue which abuts against the ovarian-stalk. Petals 
and stamens spring from the edge of the cup, where, upon falling, 
they leave well-defined scars. The stalk of the ovary springs from 
the anterior wall. 
Note——The pollen-grains are mixed up with so much food- 
material that they alone may well constitute sufficient attraction to 
insects. It is, however, noteworthy that upon cutting into the
