Vernacular name " Gallak Bet" iu Chittagong; " G a r r a " and " Cheka Bet" in
Jalpaiguri; " Dudliia Bet " at Kursong, according to Hurkill.
OBSIIEVATIONS.—Tlua, like all the other species of the group, is somewhat
variablo. It is rather closely related to D. Maniiy D. Selanochaetes und other allied
species, but is distinguishable chiefly by the fruit which is conspicuously marked with
18 narrow and doep longitudinal furrows; by the spadicos whicli before flowering are
narrowly fusiform-elongate with the outer spathe armed witli acicular spiculae and
the beak smooth; it is disiiuguishcd also by the inner spatlies being without spines
and slightly concave or almost flat. It varies a good deal in the degree of
spinescence of the outer spathe. In the specimens from Sylhet, collected by Hooker f.
and Thomson, tbo spines of the outer spathe are almost always solitary, less laminar
and narrower than in the specimens coming from Assam ami the Khasia Hills.
Tlie fmit described by Griffith and figured in PI. CLXXXVI, A, f. I l l of the
"Palms of British I n d i a " as that of 0. Jankinsianus, is doubtless that of G. Flagellim.
Cahmws nidaniijlorus GrifE. is certainly identical with Daemonorops Jcnkinsiamis. I have
seen portions of Griffith's type specimen of it in the Herbaria of Kew and Calcutta.
In a male spudis of Gri.fith's specimen of D. Jeiikinsiamcs in tiie Calcutta
Herbarium, I have observed at the apex of the spikelets, charged with normal male
flowers 1—2 flowers with a well developed ovary and therefore apparently hermnphrodite.
PLATE 1.—Daemonorops Jenkinsianus Mari. Spadix with perfectly mature fruits,
female spadix in flower with the spathes U siiti; an intermediate portiou of a leaf;
portion of a leaf-sheath with the base of the petiole. From a plant cultivated at
Buitenzorg and introduced from Sikkim (Herb. Beccari).

DESCEIPTION,—Apparently of middling size. Laaf-shealhs armed with rather long
laminar, blackish, v i r y subulate, unequal, 8'o cm. long or less, scattered or subseriat
spines Leaves (apparently those of the lower part of the plant and not cirriferous)
with numerous, equidistant, elongate-ensiform leaflets, which are green on both
surfaces and have on the upper surface the mid-costa bristly-spinulous near the
apex, and one slender nerve on each side of it, furnislied with long spadiceous
bristles; margins closely ciliate, spinulous. Male spadix with a very short prickly
pedicellar part; outer spathe fusiform or elongate-cymbiform, narrowing gradually from
a little above the middle to the beak, the whole 45 cm. long in one specimen,
armed rather densely up to the base of the beak with usually scattered spines,
which all point upwards, are erecto-patent, rather dark, thinly laminar, subulate^
and rather short, usually only 10-15 mm, long; the second spathe is entirely
covered like the first with a thin dark scurf and has a few slender spiculao along
the not very prominent carinae. Male flozoers small, 4—5 mm. long at most
Female spadiz glabrous in every part, erect, rigid, sulisessile, forming, when in
fruit, a dense thy rsoid-o void panicle, 20-35 cm. long, with the basal
internodes of the main axis short and thick (2—4 cni. in length, 8—12 mm.
thick) tumescent or swollen at the joints; primary branches 12-15 cm. long;
lower spikelets of each branch (the largest) 6-8 cm. long with a rigid zig-zag

sinuous axis, and with 6-8 distichously aiTanged flowers on each side; the
internodes or spaces .between two flowers 3-6 mm. long, cylindraceous or obsoletely
angular ; spathels with a .«hort annular membranous limb prolonged at one side
into a triangular point; involucrophorum pedicelliform, in the lower part of tbo spikelet
up to 4-5 mm. in length, in the remainder shorter, always longer than its spathels,
slightly obconical and gradually expanded into an oblique and at one side acute
bracteiform limb, rather distinctly callous in its axilla ; involucre shailowly but
almost regularly cupulnr, entire, truncate ; areola of the neuter flower distinct
bordered above with a conspicuous swollen semicircular ridge. Female flowers
oblong, 6 mm. in length; the calyx cyathiform-truncate, then split into three
parts, strongly veined externally; the corolla twice as long as the calvx. Fruiting
perianth almost entirely explanate, but the calyx has a very short base.
Fruit globose, 17 mm. in diameter, very suddenly and distinctly beaked ;
scales in 20-23 longitudinal series, not very deeply channelled along the centre,
pale brown with a faint darker intra-marginal line and a scarious, very finely
erosoly toothed margin. Seed globular, 11 mm. in diameter (not quite mature).
HABITAT.—Burma. Fruiting specimens at Zadi in Tenasseriin and at Thaungyan
{DurUll in Herbarium of the Reporter on Economic Products to the Government
of India). Vern. name at Zacii " Thwon Kyeen," at Thaungyan " Kyein
P h a n " . I consider as conspecific a male spadix also sent to me by Mr. I. H. Burkill
with the No. 29378 from Tavoy, South Tenasserim. The same number however is
appended to specimens of a Pleciocomiopgis.
OBSI£RVATIONS.—I have seen of this only very fragmentary specimens. It diSers
from the typical D. Jenkinsianus in that the male spadix with the outer spathe is
more deeply cymbiform, is armed with spines narrowly but distinctly laminar (not
bristle-like); in the scales heii!g in 2 0 - 2 3 series (not in 18); in the internodes of
the fruit-spadix being swollen at their base, and in the areola of the neuter flower
being more distinctly bordered by a swollen ring. It must bo compared also with
Z>. Manii. To this species ai-e perhaps to be referred some fragmentary
collected by Heifer in the Mergui Province (Herb. Kow.).
