fructiferous raceme is 1-1^ inch long, the slender pedicels 
1^ line long, the drupe 4 lines in diameter; the seed is cyclico- 
hippocrepiform and exalbuminous, the cotyledons being large 
and fleshy, with a very small superior radicle.

I have not seen this plant, which seems specifically distinct 
from the preceding species, differing in its leaves being more oval, 
very much smaller in size, and with comparatively longer pe- 
tioles. From the description above quoted, the leaves are oval 
and acuminate, 1 inch long, upon a petiole of equal length. 
The axillary racemes are 2 inches or more long, somewhat like 
that of the preceding species ; but the pedicels are so close as to 
appear sometimes fasciculated. 
46. Pleogyne. 
This genus was proposed by me in 1851 (Ann. Nat. Hist. ser. 2. 
vii. 43) for an Australian plant of Cunningham’s collection. With 
a habit resembling that of a Pachygone, it has oblong, coriaceous 
leaves with about five pairs of alternate nerves, which are 
arcuately connected together, with prominent reticulations ; they 
have very short petioles : it has a fructiferous axillary raceme, 
less than half the length of the leaf. In the only specimen I 
have seen, the floral envelopes had fallen away ; but Cunningham 
has noted upon it that the flower consists of three sepals, six 
stamens, and six ovaries : the ovaries which I have seen are 
seated in a single series upon a raised hairy receptacle; they 
are gibbously oval, very pilose, terminated by as many curving, 
somewhat erect, subulate styles, all connivent in the centre. 
The drupes are very small, pubescent, gibbously oval, subfleshy; 
each has a somewhat coriaceous putamen, with a small, internal, 
rounded condyle, and contains an exalbuminous seed, with large, 
fleshy, lunately curved, accumbent cotyledons, and a small su- 
perior radicle inclining towards the remnant of the style, w'hich 
is not far from the point of attachment of the fruit : this stnic- 
ture is quite that of Pachygone.
