organs ( secondary. spathes, spathels and involueres ) indistinet, being small, bracteiform 
and hidden amongst the very crowded and closely packed fruits.. Flowers sessile, 
apparently in glomerules of three of which the central one female and fertile and 
the side ones male (or neuter?). Fruiting perianth 4 mm. long, not pedicelliform, 
broadly obconic; the calyx thinly coriaceous, split down almost to the base ( sometimes 
irregularly ) into 3 ovate, acute lobes; the corolla one-third longer than the calyx, its 
segments ovate-lanceolate, not very acute; staminal urceolum as long as the calyx 
almost truncate and crowned by 6 short dentiform filaments. Fruit small, 1 cm. long 
( immature), very closely packed round the axis and apparently disposed according 
to 6 slightly spiral ` series, obovate-turbinate, narrowed towards the summit into 
a comparatively stout conic beak; scales in 18 series, convex, not channelled 
along the middle, chestnut-brown, shining, their margins ciliate or minutely fimbriate, 
tip round. Seed ( immature) pisiform ; albumen equable.

OBSERVATIONS.—À very remarkable palm, apparently the type of a new Genus, 
for which I propose the name of Zalaccella. It has many of the characters of a 
Zalacca, but is distinct; by its leaves indistinguishable from those of a Calamus and 
with non-sigmoid leaflets and by the elongate spadix with tubular closely sheathing 
spathes and cylindraceous superposed inflorescences, where the flowers are so closely 
packed together that without an accurate examination on appropriate specimens it is 
difficult to recognize the relative position of the flowers and of their appendicular 
organs. From Calamus it differs also in the non-tubular secondary spathes and. in 
the flowers arranged in 6 series on a cylindricous axis and not disposed in separate 
spikelets, and perhaps also by the 3-nate flowers of which only that of the centre 
fertile, ^I have seen of this palm only portion of the leaves and two partial 
inflorescences, apparently belonging to the same spadix, with not quite mature fruit.

OsservaTions.—It seems to me very probable that C. amarus Lour., from Cochin- 
China, is identical with C. tenuis Roxb. (See observations under that species.)
