each side, and ends in a slender taillike unarmed appendage. Secondary  spathes 
ubular, closely sheathing, slightly enlarged above where more or less minutely 
tubercled-aculeolate. The compound spikelets are spreading and inserted at the 
mouths of their respective spathes, the lower ones, largest, are 10-11 em. long and 
carry 9-10 simple spikelets on each side; the upper compound spikelets are shorter 
and have fewer simple spikelets. Tertiary spathes infundibuliform, smooth 
and glabrous at the mouth and produced at one side into a short triangular point. 
The spikelets spring erect from the mouths of their respective spathes, ure short 
(10-12 mm. long), flattened, and have 8-10 very approximate flowers on each side; 
spathels ^ concave,  bracteiform, ^ strongly striately veined and with a short 
triangular point which subtends its respective flower. Involucre shallowly cupular, 
lunately excavate on the axial side, Male flowers ovoid when very young; the 
calyx strongly striately veined.

OssERvATIONS.--ÍIn the Herbarium at Buitenzorg are preserved some sterile 
specimens of a Calamus, collected by  Korthals iu Sumatra and labelled by Blume 
himself C. ciliaris, which way be considered as really belonging to this species, 
whereas others, also from Sumatra, (but the precise locality not given,) apparently 
belong to a variety of it, oc to a very nearly allied species.

OssERvATIONS.—Ridley acknowledges in the Malayan Peninsula a C. ciliaris Bl, 
as different from C. ezilis Griff, this last he says growing only on Mount Ophir. 
He holds that the specimens from Perak collected by Scortechini and King’s 
collector, which were referred to C. ewilis Griff. by Sir J. Hooker and myself in the 
“Flora Indica” belong to C. ciliuris Bl. I have however carefully examined 
Griffith’s type specimens of C. ezilis, and have been unable to discover any appre- 
eiable specific differences between them and the other specimens collected subsequently 
by different collectors in Perak and Johore. In any case if it were proved that 
the plant from Mount Ophir is specificaily distinct from that of the other mentioned 
localities (a thing which I believe hardly possible) in no way could the latter be 
referred to C0. ciliaris Bl, as is evident on comparing my plate 129 of C. ciliaris 
from Java with plate 130 of C. exilis from Perak. 
I have seen the type specimens of C. Curtisii from Kwala Lumpur No. 2392 
with male flowers, and one from Semangko and from Bukit Kutu No. 7883, kindly 
forwarded to me by Ridley himself, and after a very careful examination I have 
been unable to discover any specific character by which OC. Curtisit could be main- 
tained as distinct from the typical C. exilis.
