Thomsoni : on a former occasion I had selected this plant as the 
type of a new genus, Baterium^, which now, therefore, merges 
into Hcematocarpus. Another specimen in the same herbarium, 
without flowers, from the neighbouring district of Sikhim, may be 
considered the counterpart of the ^ flowering specimen which 
I have referred to the typical species : it quite agrees with the $ 
plant in the size, texture, and venation of the leaves, only that they 
are a trifle broader and rounder at base. In all these specimens 
the leaves are oblong, acuminated, somewhat thick and coriaceous, 
very glabrous, subpolished above, glaucous beneath, with two 
principal simple nerves springing from the base, running parallel 
with the margin, and then arching with other, short, lateral nerves 
that rise from the midrib beyond its middle. In both species the 
^ inflorescence has from two to four panicles fasciculated in the 
axils, each on a slender rachis longer than the leaves, with short 
alternate branches, each bearing two small pedicellated flowers : 
these have twelve sepals in imbricated ternate series, gradually 
smaller outwards, membranaceous, glabrous, with ciliated mar- 
gins, and marked with coloured spots ; the six petals are half 
the length of the larger sepals, oblong, somewhat dark and 
fleshy, with two small, erect, auricular scales fixed upon their 
claw; the six stamens are opposite to them, the filament being 
short, flat, thin, widening at the apex suddenly into a larger, 
orbicular, membranaceous connective, which is galeately concave, 
with two much smaller anther-lobes widely separated, subdiva- 
ricated, and partly imbedded in its lateral margins, each open- 
ing introrsely by an obliquely longitudinal fissure ; these stamens 
are in two series, connivent, and somewhat imbricated; in- the 
centre, upon a short raised receptacle, are three abortive, small, 
subulate ovaries. The ? flower is not yet known. 
1 have adopted for the generic name that originally given to 
the typical plant, substituting for it, specifically, another to 
commemorate the name of its discoverer. The red colour of the 
fleshy sarcocarp of the fruit suggested the name Hamatocarpus.
