998 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. paspalanthus. 
pectinate spikelets (like those of some Panica); and the female spadix very different 
from the male one and with long spikelets, and speciully by the flat bony seed. 
PLATE 112.—Calamus paspalanthus Becc. Portion of the upper part of an adult 
female plant with base of leaves and of a spadix; summit and basal portion of a 
leaf; female fruit-spadix; two detached seeds, one from the dorsal and the other from 
the ventral side.—From P. B. No. 1922. 
CALAMUS PASPALANTHUS var. PENINSULARIS Becc. 
Duemonorops? intumescens Bece. in Rec. Bot, Surv. Ind. ii, 222, 
DescripTion.—Sheathed stem 2 cm. in diam. Leaf-sheaths armed at the mouth with 
long spreading spines. Ocrea marcescent. Leaves with the petiole armed near the 
base with long straight horizontal spines; leaflets up to 40 cm. long and 13-14 mm, 
broad, Male spadix with large and diffuse partial inflorescences; spikelets spreading, 
15-20 mm. long, with 10-15 perfectly bifarious flowers on each side; spathels not 
or indistinctly striately veined. Male flowers about 2 mm. long, shining; the calyx 
broadly cylindraceous, obsoletely or coarsely veined, its teeth very superficial, acute ; 
the corolla twice as long as the calyx. Female spadiz with spikelets up to 18 cm. 
long and with 25 flowers on each side; spathels irregularly armed with very small 
claws. Fruit (not seen perfectly ripe) apparently as in the type.

OssERVATIONS.— The No. 577 of the Calcutta Herbarium consists of a male 
spadix and of a leaf with the upper part of the sheath, but this is too small a 
portion for a comparison with the corresponding part of the Bornean specimens ; 
the spines at the mouth of the sheaths are long and irregularly spreading ; the ocrea 
is destroyed. The male spadix is exactly like that of the Bornean specimen but 
bears fully developed flowers, and to this cause no doubt must be attributed the 
different form of these in the two spadices. I do not know if this same cause may 
be sufficient to account for the different aspect in the surface of the spathels and 
of the involucres, for, as I have already pointed out, in the Bornean specimen 
these organs are boldly striately veined, whilst they are almost smooth in that 
from Goping.  Ridley's No. 11209 has a female spadix with almost mature fruits 
‘which do not seem to me to differ in any way from the Bornean ones, but 
the spikelets are much longer and ( very curiously) have prickly spathels. The 
leaflets in both specimens are somewhat larger than in the P. B. specimen. | 
After a careful study I have come to the conclusion that the Palm which in 
the Rec, Bot. Surv. Ind. (l. c.) I have published under the name of Daemonorops 
intumescens, probably belongs to €. paspalanthus in a not yet fertile condition, or 
perhaps in a depauperate form. Should this be true and should the Malayan plant 
after the inspection of more complete materials prove to be a species distinct from 
the Bornean C. paspalanthus, the name of C. intumescens would be an appropriate one
