coriaceous, not very densely armed with thinly and narrowly laminar, short or 1-2 cm.
long, scattered, usually deSoxed spines, which are not distinctly callous at their base ;
the second spathe also more or less covered with appressed spines; the others unarmed;
partial inflorescences 6-7 cm. long with 8-10 spikelets in all; the largest of these, thé
lower ones, 3-4 cm. long, with 4-6 flowers on each side and with the spaces between
two flowers acutely angular and 2-1 mm. long; spathels bracteiform, amplectent,
extended at one side into a broadly triangular, acute limb, which is slightly ¡shorter
than the involncrophorum; the latter very short (1-2 mm. long), distinctly callous at its
axilla, obconical and expanded at its apex into a obliquely or asymmetrically
cymbiform limb which is produced externally into a triangular acute point;
involucre elactly oupnlar, truncate, entire ; areola of the neuter flower very distinct'
and tumescent on its upper margin. FimaU J h m to be described exactly in thé
same words as those of C. tingtttUfoUm. Smier fimcrs slender, obsoletely S-gonons,
5 mm. long, narrowing towards a rather acute apex ; the corolla about twice'
or somewhat less, as long as the calyx. Fruiiing psi-ianih explanate. Fruit spadix
15-20 cm. long, dense, broadly ovate-thyrsoid. Fruit globose, very shortly and
suddenly cocically beaked, 14-16 mm. in diameter; scales in 15 longitudinal series, very
superflcially channelled along the centre, shining, yellowish or reddish-brown, usually
with a whitish scariose erosely-toothed margin and a darker intramarginal line, the
tip slightly prolonged and obtuse, marked with a very dark spot ; sometimes ébove
the dark spot of the lip may be found a white area, while the dark-coloured part
extends at the rides along the margins. Seed broader than high, somewhat flattened
12 mm. long, 11 mm. high, 9 mm. thick. '
HAEITAT.—Somatra, in the province of Palembang at Muara dua and at Batu rajah,
and also in the Island of Bangka {Teijsmann). Malayan name " Rotau Glietta "
in Baugka " Rotang Kikier," and " R. Bongkus " in Sumatra (Teijsmann). '
OBseKTATioNS,—Of Teijsmann's type specimen I have seen some loose fruits
bearing the No. 358i of the Herb. Bogor. in the Calcutta and Utrecht Herbaria.
I have also received from Dr. Treub some good specimens from plants cultivated
at Buitenzorg, undoubtedly belonging to this species. One, labelled " Calamus
sp. Sumatra, R. Geta" has a small male sjmdix 13 cm. long, including the beak, which
is about as long as the body ; the spiklets and the male flowers are exactly like those
of D. angustifolius ; but the second spathe bears a few spines on the two superficial
carinoe ; the armature of the outer one does not differ from that described for the
female spadix.
Another cultivated specimen is labelled " Oalamas sp. Bangka. R. Geta " and
bears mature fruits. The fruit scales are very variable in the same spadix fis to the
colour of their margins and tips. The mature fruit apparently does not as in D,
melanoBhaetes easily detach itself from the involucre bringing with it the fruiting perianth,
80 that the latter remains attached to the involucre while the fruit falls without it.

D. triehrous is extremely like D. angustifolius of the Malayan Peninsula, and
perhaps may be considered as a representative form in Sumatra and Bangka. It
differs, however, from D. angustifolius in the second spathe being more covered with
spmes; and in the more globular seed. The fruit of D. angustifoUm is perhaps
also more conacallybeaked than that of D. triehrous, and the petiole and rachis
in this seem less prickly than in the other.
