and not callous at their inBcrtiou. Male spadiz 1-1 "Sin. long, with 3-4 partial
inflorescences, each of which bears 8-10 spikelets. Female spadix esceedingly slender,
filiform, the one seen about 60 cm. long with only one partial inflorescence,
which boars 2-3 spikelets 15 mm. long, otherwise agreeing in the minute
characters of the flowers and their involucres with those of the typical form,
peduncular portioii of the spadix sheathed by three spathes. Fruiting perianth
almost entirely explanate under the fruit. Fruit ovoid-ellipsoid, more elongate aud
more conspicuously beaked than in the type, 1 cm. long without the 3 mm. long
beak, and 7 mm. in diam.; scales in 15 series, almost flat or slightly concave,
narrowly channelled along the middle, the margins pale, the tip marked
by a transverse dark line. Seed more elongate than in the type, its facets
slightly concave.
HABITAT. The Malayan Peninsula, on the summit of Gunong Tambang
Batak {ScortecMni No. 648 Malay name ' Rotang Pseh or Seh.'
OBSEEVATIONS.—This seems to be the alpine form of C. javemis (form
feninsularie), corresponding to the variety exilis of the Javan form. It differs from
the type in the exceedingly slender stem; in the spines of the leaf-sheaths having
a tendency to change into claws; in the small number and narrowness of the
leaflets; and in the long-beaked elongate fruit.

a leaf and an entire male spadix, from Scortecliini's No, 236 in Herb. Becc.;
another portion of the plant with a fruiting apadir from Scortecbini's No. 648
in Herb. Beccari.
CALAMUS JAVENSIS var. SUBL4EVIS Becc.
DESCBIPTION.—/SAeaiAfiti stem 7-8 mm. in diam. Leaf-sheaths green, almost
polished, distinctly striate longitudinally, smooth or with very few short straight
spines. Leaves 45-80 cm. long with a petiole sometimes very long (as much as 30
cm.); leaflets inequidistant, 4-6 on each side. Ocrea elongate, smooth, finally brittle
and deciduous.
HABITAT.—Borneo; at Kutcing on Mt. Mattang {Beccari P. E. No. 1694).
OBSEKVATION8.—The very scantily armed or almost smooth leaf-sheaths distinguish
this variety from ieirastichus. I have two leaves of it, the one with the petiole
5 cm. long, the other more than 30 cm., probably because the latter leaf belongs
to a young shoot.

DESCRiPaioN.—¿.'¿em more robust than in the type. Leaf-sheaths rather densely
covered with straight, homontal, 5-6 mm. long spines. Leaves with relatively
numerous leaflets (one leaf 55 cm. long had 10 leaflets on each side, and the two

of the terminal pair highly connate) almost equidistant, lanceolate, the basal pair
inserted very near the mouth of the sheath, and defleied. Male spadix with many
partial inflorescences ; spikelets more numerous aud nearly twice as long as in VAR,
peninsularis, very slender, sometimes branched in the lower portion and with very
many flowers. Male flowers 3 mm. long; secondary spathes now and then spinuloua.
Iemale spadix not seen.
„
HABITAT.—The Malayan Peninsula: on the summit of Gunong Tambang Batak
in the district of Perak {Scortichini No. 651").—To this variety probably belong
some incomplete specimens gathered by Sir G. King's collector between 700 and
1,000 m. at Larut, also in the district of Perak (Herb. Cale. No. 6313).
OBSERVATIONS.—Distinct from tho Javaii plant as well from the VAE. peninsuhris
(normal form) by its more robust habit and its numerous subequidistant leaflets.
The No. 6312 in the Calcutta Herbarium is more robust than Scortecbini's.
specimens and has malo spikelets more robust but not so long; the malo flowers are
also 4 mm. long, and the leaflets, at least in the portions of leaves I have seen,, do
not look exactly equidistant, though always more numerous than in the normal
Javan form; the largest leaflets are 23 cm. long and 3 cm. broad or a little more.
I n Scortecbini's specimens they vary from 15-17 cm. in length and are not more
than 3 cm. broad.

CALAMUS JAVENSIS var. INTERUEDIU8 Becc. in Hook. f. Fl. Brit. Ind. vi, 443
and in Rec. Bot. Surv. Ind. ii, 201.
DESCEIPTION.—¿'/¿EAI/IERF stem 5—7 mm. in diam. Leaf-sheaths armed with many
small, short, straight spines. Leaves 40-50 cm. long with a petiole 2-5 em. long
and with 6-7 leaflets on each side, alternate or subopposite, not quite equidistant,
lanceolate or oblanccolate, the mesial ones 15-17 cm. long aud 2 cm. broad; the
two of the terminal pair connate up to above the middle; the basal pair slightly
smaller than the others, 2-5 cm. remote from the mouth of the leaf-sheath, not
distinctly callous at their insertion on the rachis and not deflexed.
HABITAT.—The Malayan Peniiisula, iu the district of Perak {ScortecMni No. 236).
OBSERVATIONS.—More slender than VAK. polyphyllus and with fewer leaflets; the
stem is slightly larger than in VAR. tenuissimus and the leaves have more numerous
leaflets.
