D. crinitus] BECOARI. THE SPECIES OF DAEMONOROPS. 173 
about the middle, thence tapering towards the base and gradually acuminate to 
a subulate and bristly tip; they are obsoletely 3-costulate and bristly-spinulous on 
the mid-costa underneath, otherwise glabrous on both surfaces; transverse veinlets 
short, not very crowded, rather sharp on both surfaces; margins very minutely, 
appressedly, and rather remotely spinulous; the largest leaflets (those a little above 
the base) are 25-27 cm.; long and 15-20 mm. broad, the others gradually become 
shorter, but not or only slightiy narrower. Male spadiz..,...Female spadix slender and 
cylindraceous before flowering; the outer spathe crinite or with its upper part clothed 
with black, shiny, long, criniform bristles. Fruiting spadiz about 50 cm. long, 
nodding, slender, narrowly panicled; its peduncular part siender, strongly flattened, 
5-7 cm. long, its edges not very acute and slightly prickly only towards the upper 
end; all the axial parts of the spadix covered with a dark, rust y-brown, farfuraceous 
indumentum ; the lowest internode slightly clavate, very slightly flattened, 4 cm. long, 
4 mm. thick; the other internodes more or less angular, and more slender; partial 
inflorescences 5-6, the lower 9-10 cm. long and with 4-5  bifarious spikelets on 
each side ; upper inflorescences somewhat smaller; secondary and tertiary spathes 
very shortly annular-amplectent, very slightly produced on one side into & triangular, 
acute point; the lower spikelets of each inflorescence the largest, 3-4 em. long, 
with two series of slightly unilateral flowers of 2-7 flowers each; the other spikelets 
somewhat smaller; the axes of the spikelets angular, und sinuous ; spathels very 
shortly annular-amplectent, produced at one side into a short broad, acute, triangular 
point; involucrophorum very shortly pedicelliform, 1 mm. long, comparatively thick, 
angular, truncate, and very slightly produced at one side into a short triangular 
point ; the involucre protrudes very slightly beyond the involucrophorum and has 
a very narrow, annular explanate limb, around the larger flat orbicular end; areola 
of the neuter flower small, slightly concave or niche-like, the scar non-swollen. 
Flowers and fruit unknown. |

HanrrAr.— Blume writes that the type specimens of D. crinitus were collected 
by Korthals in S. Borneo on the River Dusson. The plants cultivated at Buitenzorg, 
under the name of D. manicatus, are from seed collected at Palembang in Sumatra. 
From this same locality, specimens exactly identical with Blume's typical D, criniius, 
were forwarded to Prof. Martelli in 1906 by Resident J. A. van Rijk van Alkemade. 
It is therefore quite certain that the native country of D. criniius is Sumatra. 
OBSERVATIONS.—I have seen one of Blume’s authentic specimens, of D, erinitus 
which exactly corresponds to its plate in the ‘‘Rumphia.” I have however described 
. the specimens from the plants cultivated at Buitenzorg under the name Calamus 
manicatus T. and B., Palembang, 5983 “Rotang latjap," which also exactly agree with 
Blume’s type of D. crinitus. 
The Buitenzorg specimens have very young spadices, and the outer spathes in 
their upper part densely crinite, whereas the plate in Kumphia represents this, 
part as smooth; but as Blume says that the spiculae are deciduous, it is possible 
that the spathes may appear glabrous when old, and bristly in youth. 
Miquel had already reduced C. manicatus Teijsm et Binn, to D. crinitus (De Palmis 
p. 22) and I verified the correctness of this identification by inspection of the 
authentic specimens of both in the Herbaria of Leyden and Utrecht,
