D, acamptostachys | BECCARI. THE SPECIES OF DAEMONOROPS. 209 
spredding, or slightly recurved, peeping out between the segments. Neuter flowers 
very similar in size and shape to the males. Fruiting perianth entirely explanate. 
Fruit rather small, ovoid-elliptical, rounded at both ends, distinctly beaked, 15-16 mm. 
long, 12 mm. broad; scales in 15 longitudinal series, glossy, strongly convex, deeply 
grooved along the centre, of a uniform cinnamon-brown colour and with a very 
narrow, scarious finely erosely-toothed edge. Seed ovoid, rounded at both ends, 
sinuously grooved on the surface; chalazal fovea indistinct; albumen ruminate; 
embryo basal. 
The different parts of the spadices, the spathels, involucra and flowers are of 
a uniform reddish cinnamon-brown colour. 
Hasirat.—Borneo: in Sarawak at Sibo near the sea-shore, not far from the 
mouth of the homonymous river (Beccari P. B. No. 2193), and in similar situations 
at the mouth of the Bintulu (Beccari P. B. No. 3697). Low has appended the 
vernacular name of ‘ Rotang bibuloh” to a specimen of this plant preserved in the 
Kew Herbarium and certainly collected in Borneo, but the exact locality is not 
stated. From British North Borneo a fruiting specimen has been sent to Kew by 
Governor Creagh. It is cultivated in the Botanical Garden at Buitenzorg, forwarded 
by Oxley, 
OxsERvaTions.—D. Jlongispathus in many respects approaches the species of 
Calamus of the ©. platyspathus group, especially as regards the structure of the 
primary spathes; its male and female spikelets are also exactly similar to those of a 
Calamus, as they have well conformed infundibular spathes, and approximate flatly- 
bifarious flowers. The structure of the female flowers, however, is that of a ty pical 
Daemonorops, and its relations to other species of this genus are not doubtful, It is 
a very variable plant in regard to the dimensions of the spadices. I have derived 
the description of the male plant from specimens cultivated at Buitenzorg. D. 
longispathus is somewhat related to D. longipes, and even more to D. rupiilis, though 
perfectly distinct from these as from any other species known at present.

83. DAEMONOROPS ACAMPTOSTACHYS Becc. sp. n. 
Descriprion—Stem . . €. cest i . . Leaves apparently 
large; in the small portion seen by me the rachis is bifaced, and has an acute 
smooth salient angle on the upper surface; it is armed beneath at intervals 
of 5-6 cm. with digitate (3-5-nate) confluent, straight, light-coloured, rather 
slender, 5-8 mm. long, deflexed spines and also with a few, very small,
