flower very depressed, linear. Female flowers disposed in two collateral series (not 
flatly  bifarious) and pointing upwards, ovate, 3 mm, long; the calyx coarsely 
striately veined, flat at the base with a short tube, teeth very broadly triangular, 
acute; the corolla one-third longer than the calyx, divided into 3 ovate, apiculate 
segments; filaments of the stamens united at the base into a ring which is crowned 
by 6 triangular subulate teeth. Neuter (or fertile and male ?) flowers 3—-3:5 mm. long, 
ovate-lanceolate; the calyx deeply divided into 3 concave broad lobes; the corolla 
twice as long ss the calyx, narrow and tubular at the base, divided into 3 ob- 
long segments; the stamens with sagittate, acute, apparently well-formed and fertile 
anthers. Fruiting perianth shortly pedicelliform. Fruit (when not quite ripe) globular, 
10 mm. in diam., topped by a short stout beak; scales in 18 series, yellowish, 
subshining, broader than long, with a very obtuse or round point and a reddish- 
brown, more or less distinct marginal line, the margins erosely toothed. Seed 
pisiform, irregularly globose; albumen equable ; embryo basal,

OssERVATIONS.— A small bushy not scandent species, very distinct by its short 
leaves with 5-6 fascicles of segments of the shape and size of certain willow 
leaves or of those of the olive tree, with the mid-costa furnished above with a 
few, relatively long, strong and black spines. It is also very unusual for. the 
female flowers to be accompanied by a well-developed and apparently fertile male 
flower. 
This seems a non-cirriferous species, derived from the cirriferous ones of group 
XV; it is therefore artificially placed in group V.

Drscriptiox.—Differs from the type only in the leaflets being almost without spines 
on the mid-costa and with the margins quite smooth or very remotely spinulous.

Descriptioy,—Slender, not very high scandent. Sheathed stem 6-10 mm. in 
diam. Leaf-sheaths faintly gibbous above, wholly unarmed or very scantily armed 
with horizontal or slightly deflexed pale straight 8-10 mm, long spines, which 
leave a deep impression on the sheath. Ocrea 5-6 mm. long, exsuccous, smooth, 
truncate and glabrous at the mouth. Leaf-sheath flagella filiform, slender, rather
