16 INTRODUCTION.
D. Eunstlerii) flounsh on Mount Ophir and on the Gunong Tambang Batak, between
500 to 1,500 metres above the sea.
I t aeoms that those species which show a predilection for high mountains have
a tendency to shorten their stems and to lose their seandent character.
Generic diferenaes between
DAEMONOROPS.
Zef?/-sAfiii/iS—Never flagelliferous.
Oeicfi—Always very short; only in D. uninm it
is prolonged into two long appendages.
Z?ayes~The upper always more or less cirriferous.
Always narrow and aoiiminate j never
rhomboidal nor premorse.
After flowering open, short oymbiform
or flat, decidiiouB ; never armed with olawa.
Spadices—Form a panicle, mostly a very short one
no thorns on the axial parts,
and Calamus.
whole groups, in others
CALAMUS.
Flagelliferous or not.
Oo-en—Ofteu greatly developed, at other times
short.
Z«i7i-««—Cirriferous in
not.
Xen/eis—Variable.
S^jniAw—Always tubidar and tight-Eheathing; at
least in their lower portions almost always
more or less armed with claws.
iS^odiciS—For the most part greatly elongated and
flagelliferous; or if panioled, set with olawa on
the axial parts.
Spike lets— almost always have perfeotly bifari-
0U8 flowers, and infundibular spathels.
Spikelets—P have almost always infundibular
spathels.
Tnvolucrophorum—Is either infandibular or oupular.
SpikeUh^S very rarely comb-like, most
flowers imperfectly bifarious, with soale-like or
bracteiform, not tubular spathels.
Spxkekfs—S have almost always very short annular
spathels. (In D. longUpathus and D.
ruptitis these are infundibular).
J?ii)o/«cj-c>pAorMM—pedicelliform truncate, and almost
without a limb ; bears the involucre at its
extremity.
Jfowpo/wcr«—Usually tmnoate, more rarely oupular.
Ylowers—'^'i'ùi. truncate or ± superficially B-dentate
calyx ; corolla about t-wics as long as calyx.
Seed—Always ruminate, has the foveola ot the
chalaza indistinct, pit-like, or reduced to a narrow
fissure, very rarely taking the shape of a oanal
nenetrating within the seed.
Embryo—Always basal.
Imolwn —Oupular.
J'^oiisrs—i>with deeply tri-lobed or 3-partite calyx;
corolla about the same length as calyx.
Seed—Mostly witti the albumen homogeneous or
with intrusions of tlie superficial integument; the
foveola of the ohalaza very distinct and deep-
In relatively few species the seed is more or less
deeply ruminate. *
Most often basal, but sometimes lateral.
D. longispaihus and D. ruptilû are, perhaps, the species whioh approach nearest to Calamu».
