This variety I have not seen. In the form of its leaves it seems 
to approach more to D. elliptica ; but the presence or absence of 
the basal glands on the upper surface of the leaves will deter- 
mine to which species it belongs. The shortness of its racemes, 
which are only half an inch in length, and its being only two- 
or three-flowered, if a constant character, would suggest the 
possibility of its being accompanied by other marked specific 
ditferences.

A tree about 15 feet high, with a habit quite as subscandent 
as the preceding species, and with its branchlets half-twining, 
half-pendulous : its leaves are from 2 to 3 inches long, 12 or 
14 lines broad, upon a petiole 3 lines in length; they are hardly 
distinguishable in form and appearance from the former, and in 
both species they assume a reddish hue in drying ; below they 
are of a pale green, with a reddish midrib and prominent ana- 
stomosing nervures. In this species more particularly, small 
round glands with an umbilicated centre are often, but not con- 
stantly, found immersed in the forked points of the nervures on 
the under side only of the leaf, and are never seen upon the 
upper surface as indicated in the preceding species. In both 
species the stipules are seen on each side of the insertion of the 
articulated petiole, linear, acute, erect, and half a line long, each 
springing out of a gland similar to those seen on the under 
side of the leaf. The racemes, which grow out of the extremi- 
ties of the younger branchlets, are generally about 1^ inch long, 
with about eight to ten flow'ers placed alternately ; the pedicel 
of each flower is a line in length, and proceeds from a prominent 
nodule formed of three confluent glands, which bear as many 
deciduous bracts, similar to those which support the stipules. 
The sepals are 4 lines long, 1 line broad, and retrorsely pubes- 
cent on both sides. The corolla is of a yellowish white (not
