above, more or less distinctly pedicellate, callous at the axilla next to the axis, 
with a shallowly concave limb; involucre larger and exceeding the involucrophorum, 
shallowly cupular or almost flat with a large central scar and an irregularly circular 
limb; areola of the neuter flower very depressed, linear, with a punctiform scar 
in the centre. Female flowers small, about 3 mm. long. Fruiting perianth distinctly 
pedicelliform; the calyx flat at the base, the tube cylindraceous, the teeth not 
distinctly veined, broadly triangular, acute; segments of the corolla slightly longer 
than the lobes of the calyx and narrower than these. Fruit globose, topped by a 
very small conic acute beak, 8-10 mm. in diam.; scales in 21-23 series, faintly 
and narrowly channelled along the middle, subshining, light-yellowish with a reddish- 
brown rather acute tip; margins indistinctly erosely toothed. Seed irregularly globose, 
6 mm, in diam., coarsely tubercled and grooved or broadly pitted on the back, with 
a round and deep chalazal fovea in the centre of the raphal side; albumen subhomo- 
geneous, some of the pits sometimes penetrating into its mass; embryo basal. 
Hasrrar.— Hong-Kong : where it was discovered in fruit in March 1875 by 
Dr. G. Dods in the valley of Wongneichung, Hance No. 18979 in St. Petersb. 
Herb.; it was found again in that Island also in fruit by C. Ford in 1882 (Herb. 
Kew); in Hainan, Henry No. 8213 in Herb. Berol. (male specimen). 
OnsERVATIONS.—AÀ species very distinct by the conspicuously fascicled arrange- 
ment of its few oblong-lanceolate leaflets; its small dimensions; the small round 
fruit with pedicelliform perianth, propped up by a subpedieelliform involucrophorum. - 
I have described the male spadix from Henry’s specimen, which seems to me 
to agree perfectly with Hance’s and Ford’s typical fruiting specimens.

Description.—Suberect with an elongate stem or subscandent (?), rather large and 
robust. Sheathed stem 3-5 cm. in diam.; naked canes 2-25 cm. in diam. with 
relatively short internodes (about 15 em, long).  Leaf-sheaths thickly coriaceous or 
almost woody, cylindraceous, rather short, gibbous above, obliquely truncate and 
naked at the mouth, entirely covered, chiefly in their upper part, with small very 
short and broad-based spines, which are very approximate, solitary or subseriately 
confluent and are often reduced to small pungent tubercles or sometimes have a more
