74 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. scutellaris. 
Herbarium, but most certainly the type specimen of C. giganteus, reproduced in my 
plate 197, is an entirely different plant from any of the forms of C. ornatus. 
C. giganteus approehes C. Manan, and perhaps corresponds to the plant described 
by Ridley (l. c.) under this name. 
CALAMUS ORNATUS Bi. var, cELEBICUS Becc. n, var. 
Description.—It differs from the other varieties by. the fruit being more elongate, 
with quite black scales, but especially in the seed, which is oblong, truncate and 
emarginate at the base, strongly flattened with a very uneven surface; is boldly 
tubercled and pitted, but without crests or ribs; it is 16-18 mm. long, 10-11 mm. 
broad and 7 mm. thick. ‘he fruit without the perianth measures 3 cm. in length, 
and is }6-18 mim. broad. 
Hasitat.—Celebes: in the Province of Minahassa (Menado), Koorders No. 184048 
near Paku ure, and Nos. 183908, 183948, 184028, 184088, in Buitenzorg Herbarium.

OssERvATIONS.— Ridley writes: ‘‘A plant in the Botanic Garden was unisexual, 
the spikes containing male and female flowers in the pairs.” But certainly C. Scipionum 
is a dioecious plant, as I have seen specimens of it with male flowers only (Plate 155); 
apparently however the female plant has the neuter flowers more conspicuous and more 
developed than usual, and perhaps may also have fertile stamens. 
In the Buitenzorg Herbarium there is a portion of a specimen collected by 
Korthals in Borneo and labelled in the hand-writing of Blume '* Daemonorops fissus Bl.” 
This specimen, consisting of a portion of a leaf, is undoubtedly referable to €. Seipio»um,

DrscRrPTION.— Apparently a rather robust plant. Stem . . . Leaves i 
Female spadiz rather large and robust, and, as far as can be judged from the frag- 
ments, dense, twice branched and non-cirriferous; partial inflorescences 20-30 cm, 
long (or at times more?), with few (3-4) rather approxmate, short (10 cms 
long more or less) rather stout branches; primary spathes . . ; secondary spathes 
very briefly tubular in their basal part, slashed longitudinally into several Stripes, 
brown, exsuccous, membranous, quite unarmed, glabrescent, finely striate, about as 
long as their respective branches, which are inserted about half way up their length ; 
the axis of the partial inflorescences is thickish, has short internodes, is obsoletely 
‘angular or subterete and is quite smooth; the branches are short, arched, have only 
4-6 irregularly spreading, brachiate, rather approximate spikelets; the axis of the
