142 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. K. hallieriana. 
axillary callus, obtusely toothed leaflets, sad thickish rusty-furfuraceous wrinkled 
anse. 
Ridley writes of K. Wallichiefolia that, although a common plant in Singapore, 
he never succeeded in finding flowering specimens. Probably this Rattan is much 
sought after by the natives, and is gathered before the plant has attained its complete 
development. 
OssERYVATIONS.—It is one of the largest, but a very imperfectly known species, 
very similar to K. laciniosa, but as noted by Griffith, distinguishable by the obtuse- 
ness of the teeth of the leaflets, and I may add, by the thick callus and trans- 
verse rima occurring in the axilla of the petioles, and by the thickish rimulose 
anse of the leaflets, which in the living plant apparently must be somewhat fleshy 
and subterete and not strongly flattened as those of K. laciniosa. 
The same peculiarities differentiate K. Wallichiafolia, from R. Teysmannii and — 
K. feror. 
According to the description and plate given by Griffith, X. Wallichicefolta 
differs from K. laciniosa and K. Teysmannii also in the spikes having the spathels 
produced beyond the wool of the flower-bracteoles, instead of being almost entirely 
hidden by the tomentum. Griffith gives for his Calamosagus Wallichicfolius, the 
_ Malay name of “ Retang Simote” (Sumut or the “the Rotang of the Ants." (This 
name, however. is strictly speaking given to the Korthalsias which harbour ants in 
their inflated ocree ; but possibly ants are clients of this Palm also, on account 
of the. calluses ARA in the axillas of the petioles, and apparently also of the 
anse which probably ai the function of extra-floral nectaries. 
PLATE CIE Ae Wallichisefolia Wendl.—Intermediate ^ portion of the 
sheathed, stem and base of a leaf (note the callosity at its axila); upper portion 
of a leaf from an adult plant. From Ridley's specimen No. 10407 in Herb.

21. KoRrtHALsIA HALLIERIANA Bece. n. sp. 
DescrIPrION.—Skeathed stem 14—16 mm. in diameter, with long internodes. Lug: 
sheaths not gibbous above, gradually passing into the petiole, almost smooth, present- 
ing only a few short spines along two lines on the ventral face. Ocree short, 
truncate, perishable, closely sheathing, unarmed. Leaves rather large; petiole 
25—28 em. long, 6 mm. broad, and having a conspicuous axillary callus, flat above, 
convex and armed with a few solitary scattered claws beneath; the pinniferous 
part, 60 cm. long, bearing 5—6 leaflets on each, side of the rhachis; the rhachis 
is angular, rusty furfuraceous, irregularly armed beneath with. solitary or ternate 
claws, the cirrus rather robust. The leaflets are all opposite, or nearly so (in 3 
leaves), rigid-papyraceous. concolorous, or withoui any special indumentum on the 
lower surface, rhomboidal, cuneate in their lower half, and having the upper margin 
obtusely* undulately-toothed, and suddenly terminated by an acuminate tip, have 
7—9 radiating main nerves, and the transverse veinlets slender, and rather approxi- 
mate; the lowest leaflets are the largest, 13—20 cm. long and 9—13 cm. wide;
