it is called by the natives “Rotang Saga Boeh” and a portion of a leaf and some 
detached fruits collected in the State of Johore by Mr. Pears, who assigns to it the 
name of ‘ Rotang Segar” (Ridley No. 10716 in Herb. Kew) A portion of a 
fruit-spadix without leaves, apparently not differing from the above, is also preserved 
in the Caleutta Herb, with the label * Ridley No. 11382: Batu Pahat, State of 
Johore: Rotang Segar.” Henrici gives the Bornean names of ''Ujanjang" and 
* Rotang Latong," adding that its canes are much valued by the Malays. 
OBSERVATIONS.—I have seen of this a portion of a leaf from the authentic 
specimen described by Blume, which has afforded me the means of recognising beyond 
a doubt this species in some large sterile but otherwise complete specimens, obtained 
from plants cultivated in the Buitenzorg Gardens and kindly forwarded to me by 
Dr. M. Treub. Scortechini’s specimen is also sterile, but agrees pretty well with the 
type specimen of Blume. The sheathed stem of this is however more slender (10-12 
mm. in diam.) than in the cultivated specimens of which I have made use for the 
description above and the leaf-sheaths are armed with longer spines. Scortechini in a 
note added to his specimen says that the internodes are 25-30 cm. long and the 
leaflets silvery-pale beneath. C. cesius is well characterised by its underneath 
glaucous, remotely geminate, not numerous oblanceolate 5-costulate leaflets. 
It is certainly a near ally of C. simplex in which, however, the leaflets are 
not mealy-glaucous beneath. _ 
The very “incomplete specimen from the State of Johore preserved at Kew 
(Ridley No. 10716 with the native name of Rotang Segar) is identical with that of 
Scortechini No. 454 and it is accompanied with some almost mature detached fruits, 
. These are ellipsoid-ovoid, very suddenly narrowed into a rather long and not very 
thick beak, 18 mm. long including the beak and the fruiting pedicelliform perianth, 
19 mm. broad; scales in 18 longitudinal series, polished yellowish-straw-coloured, 
convex, very narrowly and deeply channelled along the middle with a small 
triangular acute point aud an almost concolorous erosely toothed margin; seed ovoid, 
rounded to both ends, 10-11 mm. long, 8 mm. broad, minutely pitted on the 
surface, the chalazal fovea, round, small, not very distinct; albumen not very 
deeply ruminate; embryo lateral near the base. 
Ridley’s No. 11382 of the Calcutta Herb. consists only of a partial inflorescence 
55 em. long with 6 spikelets on each side; in this specimen the secondary spathes 
are tubular, very slightly enlarged in their upper part, closely sheathing, unarmed, 
truncate and entire at the mouth, very shortly apiculate at one side. The spikelets 
are vermicular, rigid, inserted outside the mouth of their respective spathes with a 
rather distinct axillary callus, the lower ones 10-12 em. long, with 10-12 flowers 
on each side, the upper ones shorter; the spathels are infundibuliform, truncate and 
entire, extended on the outer side into a very short and broad triangular point, the 
involucrophorum is exert from its own spathel and laterally attached to the base of 
the one above, very shortly cupular, bidentate on the side next to the axis, the 
involucre very shallowly cupular, very slightly exceeding the involucrophorum. The 
fruit is as described above.
