‘164 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. . (D. Calapparias 
10-15 em. long, erect, appressed to the main: axis, with 4-5 pinnately set, gradually 
diminishing spikelets on each side ; secondary spathes very short, annular, prolonged 
at one side into a scale-like, triungular, acuminate point; spikelets rigid, rather 
thick, with their axes acutely trigonous and when bearing fruit diverging at an 
angle of 45° and with a distinct axillary callus ; the lower spikelets of each 
inflorescence 5-7 cm. long, with 2 series of 7-8 slightly assurgent flowers; the 
upper spikelets somewhat shorter, flowers fewer; involucrophorum thick, 3-4 mm. long, 
angular, obconic; involucre appearing like a short prolongation of the. involucrophorum 
and terminating in a discoid flat surface; areola of the neuter flower niche-like, 
rather deep, flower scar horizontal and not swollen. Fruiting perianth very shortly 
pedicelliform. Fruit comparatively very large, spherical, very shortly and broadly 
conical-beaked or mammillate, 22-24 mm. in diameter (when perfectly mature); scales 
arranged in 18 longitudinal series, very narrowly and sharply grooved along the 
centre, of .a uniform light straw-colour, convex, shining, with a very narrow, 
slightly discoloured, erosely-toothed margin; tips not produced, obtuse. Seed 
somewhat irregularly globular, 16 mm. in diam. slightly ventricose on the raphal 
side, very minutely tubercled and pitted, strongly ruminate with very narrow and 
numerous channels; the chalaza punctiform, superficial, inconspicuous.

OpseRvaTIoNs.—Related to D. ochrolepis, but distinguishable by its very narrowly 
ensiform leaflets and larger fruit, The fruit of D. Clemensianus is about the size 
of that of D. Calapparius and is one of the largest in the genus, 
PLATE '67.—Daemonorops Clemensianus Bece.—Intermediate portion of a leaf (upper 
surface); lower and intermediate portion of a spadix with mature fruits; upper portion 
of a leaf-sheath with the base of a petiole and an entire male spadix in flower; one 
seed entire and another longitudinally cut through the embryo. From Clemens’s
