€. Zollingerii.) BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 389 
em, long with 15-20 distichous flowers on each side; spathels very short and 
closely packed, broadly infundibuliform, truncate, extended at one side into 2 very 
short point, the margin entire, ciliately furfuraceous when young; involucrophorum 
unilaterally subinfundibuliform, narrowed to the base and therefore distinctly 
pedicellate, not exceeding its own spathel and attached to its bottom, sharply and 
acutely two-keeled on the side next to the axis; involucre cupular, rather deep, 
truncate, deeply excavate and 2-toothed on the side of the neuter flower, of which 
the areola is rather deep, lunate but often somewhat vertically evolute and sharply 
ordered, Female flowers conical-ovoid, 4 mm. long; the calyx with 3 short small 
triangular acute teeth; the corolla pergamentaceous, barely longer than the calyx, 
divided down to about midway into 3 lanceolate acute lobes; stamens forming with 
the united bases of the filaments an urceolate cup as high as the 2 of the corolla 
and crowned with 6 short triangular acute teeth; anthers short, very broadly sagittate, 
with acute tip and auricles; ovary turbinate, surmounted by a trigonous columnar 
style of about the same length; the stigmas elongate, acute, recurved, projecting from 
the connivent perianth. Neuter flowers long, permanent, smaller and thinner than the 
female ones. Fruiting perianth explanate, and subtended by the  sub.pedicelliform 
involucrophorum. wit (immature) small, globose, 6 mm. in diam. and 9 mm. long, 
including the brown acute apical mucro (this 1:5 mm. long); scales in 18 longitudinal 
series, shining, pale-yellow, superficially channelled along the middle with a very 
narrow brown intramarginal line, the margin scarious and minutely erose, the point 
dark-coloured, short heiry-fimbriate when seen under a lens. 
Hasitat.—Celebes: in the littoral jungle at Boni, collected by Zollinger in 
November 1847 (Zoll. No. 3493) in Herb. Boiss. and Herb. Bruxelles, From North 
Celebes I have seen a specimen in Herb. Berlin collected by Warburg at Bojong 
in the province of Minahassa. 
OssERvATIONS.— A note of Zollinger appended to the distributed specimens declares 
this to be a very large and scandent species about 20 m. high. A fine specimen 
from a plant said to be from Menado in North Celebes, cultivated in the Botanical 
Garden at Buitenzorg, No. 3920, and forwarded to me by Dr. Treub, proves the 
huge dimensions of this species. I have no doubt that this specimen belongs to the 
same species as Zollinger's No. 3439, but probably the cultivated plant has acquired 
larger. dimensions than the wild ones. On the Buitenzorg specimens I have based 
the description of the vegetative organs; the male spadix has been described from 
Zollinger’s No. 3433 preserved in Martius Herbarium at Bruxelles, and the female one 
from another specimen, also of Zollinger, with the same number and apparently of 
the same gathering in Boissier’s Herbarium. I have added some general characters 
from Ahe spadix of the above-mentioned cultivated plant. 
I have received from the Leyden Herbarium a portion of a fruiting spadix with 
perfectly ripe fruit, which portion was intermingled with specimens of C, Burckianus 
and had the label **Rotang Mapait, Celebes. De Vriese.” This specimen in fruit, 
I have little or no doubt, belongs to C. Zoellingerii with which it agrees perfectly in 
the shape and size of the pedunculate spikelets, as well as in the spathes, spathels, 
involucres and fruiting perianth. The fruit (which indeed is very similar to that 
of C. Burckianus) is globose, 1 cm. in diam.; shortly and very abruptly mucronate;
