crimson ; calyx 3-4 mm. long, campanulate, strongly many-nerved, 
the teeth short, triangular-ovate; corolla infundibular, more than 
twice the length of the calyx, strongly about 25-nerved, the teeth 
2 mm. long, ovate, obtuse; stamens many times the length of the 
corolla; fruit not seen

In some respects this appears more like a Pithecolobium, but 
its venation marks it a Calliandra, in the section Macrophyllae.

Var. (?) ANGUSTIFOLIUM var. nov. 
The leaflets are 1.5 cm. long by about 3 mm. broad at the 
clasping cordate inequilateral base, which is conspicuously yellow- 
tufted, the margin is ciliate, the lower surface pale and very prom- 
inently reticulate, the rhachis hirsute. It appears to me to be a 
distinct species, but flowers are lacking. 
Vic. Guanai, 1892 (1606).

A large tree, the foliage softly pubescent A^ the upper 
leaf-surfaces; branchlets unarmed, stoutish, angular, flexuous, the 
internodes short amd unequal; stipules not a ae rent ; petioles

the internodes of the rhachis, stout, angled; pinnae about 6 pairs, 
ves ips d opposite, their petioles swollen at the base, the Jowest 
e uppermost 4 -jugate; glands 1 mm. below the insertion of 
ik leaflets, conspicuous, oe a to brown; leaflets regu- 
larly enlarging upward, 2.5—5 cm. long, 1.5-4 cm. broad, on peti-

subrotund at base and apex, shortly and bluntly cuspidate, entire, 
slightly revolute, coriaceous, dark-green and glabrous above, pale
