pectinate spikelets (like those of some Panica) ; and the female spadix very different
from the male one and -with long spikelets, and specially by the flat bony seed.

CALAMUS PASPALANTHUS v a r . PENISSULARIS Beco.
Baemonorops ? intumescens Becc. in Roc. Bot. Surv. Ind. ii, 222.
DESCKIPTION.—Sheathed stem 2 cm. in diam. Zeaf-sheaths armed at the mouth with
long spreading spines. Ocrea raarcescent. Leaves with the petiole armed near the
base with long straight honzontal 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 oc 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 spadix 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.
HABITAT.—The Malayan Peninsula : at Goping, Kiinstler No. 577 in Herb. Cale.
Batu Pahut, Patani, in the State of Johore, Ridley No. 11209 in Herb. Berol.
OBSERVATIONS.—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 correspor iding 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 Borneau specimen but
bears fully developed flowers, and to this cause no doubt must be attributed the
difierent form of these in the two spadices. I do not know if this same cause may
be sufficient to account for the difierent 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 Reo. Bot. Surv. Ind. (1. c.) I have published under the name of Daemonorops
intumescens, probably belongs to C. 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 bo a species distinct from
the Bornean C. paspalanthus, the name of C. intumescens would be an appropriate one
for it.

The specimens which I now consider as the young stage or as a form of C
paspalanthus and which received the name of D. intumescens were gathered by Father
Scortechini in the State of Pcrak. I have seen two other specimens very similar
to these, sent from Johore to the Berlin Herbaiinm by H. N. Ridley. Scortechini'a
specimens have a sheathed stem 10-13 mm. in diain. ; the leaf-sheaths are very
conspicuously pufied up or inflated-tumescent at the base of the petiole, are almost
black, opaque, very finely scahridnlons (when dry), sparsely armed with scattered
1 - 2 cm. long spines; the ocrea is speedily marcescent and vanishing, not fibrous;
the leaves with the petiole are armed at the margins near the base with horizontal
rather close very slender spines; the leaflets are exactly as in the type but smaller,
15-16 cm. loDg, 8-9 mm. broad.
