134 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA, (C. longispathus. 
very minutely spinulous; the intermediate leaflets are 25-30 em. long, 3-455 cm. 
broad; those near the base are usually narrower but not shorter, those of the 
upper end somewhat smaller. Other parts unknown. 
Hasrrat.—N, W. Dutch Borneo in the Residency of Sambas at Sungei Sibow 
(Haller No. 1194); at Amai Ambit ‚Hallier No. 3310); and at Liang-gagan (Hallier 
No. 2614). All numbers in the Buitenzorg Herbarium. 
OBsERVATIONS.—Very closely related to the Sumatran €. Ulur, from which it 
differs in its smaller size, in its leaf-sheaths being less spinous, but especially in 
its distinetiy pluricostulate leaflets. Of C. pseudo-Ulur I have seen only sterile 
specimens, and those of C. Ulur in flower examined by me are very incomplete; 
a rigorous comparison of the two is therefore impossible. 
SurPL. Prare 77.—Calamus pseudo-Ulur Bece. Two portions of sheathed stem 
(observe a little below their mouths the rudiment of a flagellum or of a mm 
upper and intermediate parts of a leaf. (From Hallier’s No. 2614 in Buitenzorg 
Herbarium.)

DzscRiPTIoN.— Apparently of moderate size. Leaf.sheaíhs . . . Leaves rather 
large and elongate, subcirriferous, the rachis being furnished at its summit with a few 
distant, diminutive leaflets; petiole rather robust, 12 mm, broad, with the upper 
surface almost flat and dull, and the lower convex, polished and armed at the 
sides with rather robust solitary claws; the margins sharp and armed with very 
small, horizontal spines; the first portion of the rachis is grooved at the sides 
from the insertion of the lowest leaflet, and is almost rectangular in transverse 
section: on the lower surface it bears strong solitary claws at the sides but none 
on the central line: towards the end it is bifaced, with an acute smooth salient 
angle above, and is irregularly armed with robust, solitary or more or less 
approximate claws beneath. The /eaffeós, in the small portions of a leaf seen by 
me, are very inequidistant and remote, ensiform, gradually narrowing to an acute 
base, and from the middle upwards gradually acuminate towards the upper 
end, but more suddenly when nearing the extreme apex: they are papyra- 
ceous, rather rigid, almost glossy above, dull and slightly paler beneath, 
distinctly and rather sharply 3-costulate, and are also more or less distinctly 
and irregularly striate, especially on the lower surface, by several secondary nerves ; 
all nerves are smooth on both surfaces; transverse  veinlets very numerous, 
continuous and sharp on both surfaces; the margins are rather conspicuously 
thickened and minutely and remotely  spinulous, the  spinules becoming more 
approximate and longer at the sides of the apex; the largest leaflets seen by me 
(those a little above the base) are 55 cm, long and 25 mm. broad; those near 
the upper end are much shorter and slightly narrower; the uppermost are quite 
rudimentary. Male spadiz . . . Female spadiz is elongate and stiff, about 9 m. 
long in one specimen, ends in a slender, unarmed, rather short caudiculum, has a 
plano-convex, very acutely two-edged, 12 mm. broad, peduncular part, which 
gradually passes into the lowest spathe; this spathe is very long (45 cm.), rigid,
