of the sheathed stem; lower and intermediate portion of a leaf. From Hallier’s 
type specimen in Herb. Bogor. 
50. DAEMONOROPS MICROSTACHYS Becc, 
This species, which was known only through very incomplete specimens 
collected by Lobb near Bruni, has been found again by H. Hallier in Dutch N.-W. 
Borneo at Sungei Sambas, in the homonymous Residency (No. 1086 in Herb, Hort. 
Bot. Bog.) The specimens fiom this locality appear to have the same characteristics 
as those from W. Borneo, and seem to exclude the hypothesis that D. microstachys 
represents a case of nanism of D. Aystrix. These specimens reveal a small, very 
slender, erect plant. The sheathed stem is 15-18 cn. in diam., the naked canes 
8 mm. thick; the leaf-sbeaths are split open a long way down on the ventral 
side, and are armed, more or less distinctly, with obliquely-seriate, rather large, 
laminar spines, and smaller series of minute spiculae. eaves never cirriferous in the 
specimens seen by me', about 80 cm. long; petiole subterete, armed with scattered, 
robust, 2-4 em. long, straight spines; leaflets numerous, equidistant, linear-lanceolate ; 
the largest 20-22 cm. long, 11-12 mm, broad, bristly on 3 nerves on the upper 
surface, but only on the mid-costa on the lower. Spadices axillary, very slender, about 
15 cm. long on the whole; the panicle very small, short, and with very few 
branchelets, borne on a slender flattened spinulous pedicellar part; the outermost 
spathe is spathulate, coriaceous, bidentate at the apex, about 5 em. long, spinous on 
a dorsal central carina; the lowest internode of the flowering panicle is distinctly 
clavate; the partial inflorescences are very small, and have a very few, very short, 
few-flowered spikelets. Fruit globular, 9 mm. in diam., terminating in a very short 
broadly-conical, acute beak; scales almost polished, of a cinnamon-brown colour, 
with a narrow light-coloured marginal line, neatly and narrowly grooved along the 
centre; the margins very minutely erose-ciliate. Seed globular,

portion of a sheathed stem with an entire leaf and one spadix in situ, with 
immature fruits; spadix with mature fruits. From  Halliers No, 1086 in Herb,

51, DArMONOROPS HYSTRIX VAR. EXULANS Becc. n. var. 
DescripTion.—Slender (seandent?). Sheathed stem 1-1'5 cm. in diameter. Leaf-sheaths 
striate longitudinally, armed on the body with scattered, narrowly-laminar, 1-2 cm. 
long spines, and more or less furnished on the ventral side of their upper part, 
along the centre, with rigid, horizontal, blackish, needle-like spiculae, 1-1:5 cm. 
long, which become slightly broader and are, at most, 3-4 cm. long on the 
margins of the mouths of the leaf-sheaths, where they are ascendent or spreading, 
and never attain the extraordinary size observed in the forma typica, or in its 
variety or. In other respects, the var. ezulans of D. Hysírir does not differ 
from its var. minor except in its still smaller dimensions. The leaves are from
