44 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [D. Jenkinsianus, 
Vernacular name “Gallak Bet” in Chittagong; “ Garra”: and ''Cheka Bet” in 
Jalpaiguri; “Dudhia Bet” at Kursong, according to Burkill. 
OnssnvATIONs.— This, like all the other species of the group, is somewhat 
variable. It is rather closely related to D. Mani D. Xelanochaetes and other allied 
species, but is distinguishable chiefly by the fruit which is conspicuously marked with 
18 narrow and deep longitudinal furrows; by the spadices which before flowering are 
narrowly fusiform-elongate with the outer spathe armed with acicular spiculae and 
the beak smooth; it is distinguished also by the inner spathes 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, the spines of the outer spathe are almost always solitary, less laminar 
and narrower than in the specimens coming from Assam and the Khasia Hills. 
| The fruit described by Griffith and figured in Pl. CLXXXVI, A, f. III of the 
“Palms of British India” as that of C. Jenkinsianus, is doubtless that of C. Flagellum. 
Calamus nutantiflorus Griff, is certainly identical with Daemonorops Jenkinsianus, I have 
seen portions of Griffith’s type specimen of it in the Herbaria of Kew and Calcutta, 
In a male spadix of Grifith's specimen of D, Jenkinsianus in the 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 hermaphrodite. 
Piate 1.—Daemonorops Jenkinsianus Mart, Spadix with perfectly mature fruits. 
female spadix in flower with the spathes ča situ; an intermediate portion of a leaf ; 
portion of a leaf-sheath with the base of the petiole. From a plant cultivated dt 
Buitenzorg and introduced from Sikkim (Herb. Beccari). 
DAEMONOROPS JENKINSIANGS Mart.? var. TENASSERIMICUS Bece. 
Description.—Apparently of middling size.  Leaf-sheaths armed with rather long 
laminar, blackish, very subalate, unequal, 2:5 em. 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,. furnished with long spadiceous 
bristles; margins closely ciliate, spinulous. Male spadiz 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 em. 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 aude 
covered like the first with a thin dark scurf and has a few slender spiculae along 
the not very prominent carinae. Male flowers small 4-5 mm. long at most 
-Female spadiz glabrous in every part, erect, rigid, subsessile, forming, when in 
fruit, a dense  thyrsoid-ovoid panicle, 20-35 cm, long, with the basal 
internodes of the main axis short and thick (2-4 cm. in length, 8-12 mm. 
thick) tumescent or swollen at the joints; primary branches 12-15 em, long; 
lower spikelets of each branch (the largest) 6-8 cm. long with a rigid boas
