122 ANNALS OF THÈ ROYAL BOTANIC GARDEN, CALCUTTA. ^ K. debilis, 
leaflets are 15-22 cm. long, and 4-5'5 cm. wide; the upper ones are somewhat 
smaller, 10-15 em. long and 3-45 cm. broad; the ansae. are 6-10 mm. long, 
rusty-furfuraceous, somewhat flattened, callose in their axillas.  Spadix unknown. 
Hasrrar.—Dutch Borneo. First collected by Teysmann (No. 16714 in Buitenzorg 
Herbarium), who gives the native name “ Djelundengan." Found again recently 
by Heyne at Bandjermasin (No. 24 bis in Buitenzorg Herbarium) and at Pon- 
tianak (No. 2544 in Buitenzorg Herbarium). 
OssERVATIONS.—[t is a slender palm, somewhat resembling K. rigida, from 
which it is easily distinguishable by the short ocreae, perishable in their upper 
part, but not forming a fibrous net; by its short leaves having very short petioles. 
and only 6 leaflets in all; by the leaflets being rather distinctly 3-costulate, and 
having the sides in the cuneate lower part slightly curved | in converging towards 
the base, and not, as usual, quite straight ; they are also, more distinctly than in 
other species, dotted below. 
Probably the specimens of K. rigida mentioned by Blume (Le), as collected 
by Korthals in Borneo belong to K. paucijuga. 
Puare 75.—Korthalsia paucijuga Becc. The terminal part of a plant. From

Description.—Very slender. Sheathed stem 5-10 mm. in diameter, the caneg 
with a dull (non-vitreous) surface. Leaf-sheaths elongate, fugaciously and partially 
rusty-furfuraceous, usually sparingly, yet at times rather thickly, armed with very 
short tuberculiform spines or quite smooth, coriaceous, but of a flabby structure 
along the ventral or outer aspect, especially ‘in their upper part where usually 
disintegrated into a fibrous net. Ocreae 3-8 cm. long on the whole, more or less 
armed with short ascendant prickles, or otherwise smooth, closely sheathing, but 
having a short permanent coriaceous base, and thinly membranous and more 
or less disintegrated into a fibrous, finally deciduous net in the remainder.  Znmterme. 
diate leaves 30-35 cm. long in the pinniferous part, ending in a cirrus about as 
jong, very slender, and very minutely clawed. Petiole short, 2-3 cm. long 
or longer in leaves of young plants, flattish or slightly concave above, 
rounded below. Rhachis armed with scattered, small claws. Leaflets 4-5 on each 
side of the rhachis, alternate, papyraceous. whitish beneath, especially when young, 
15-18 cm. long, 4-6 cm. broad, cuneate-rhomboidal, ^or triangular above the 
middle or in their upper third part, and gradually cuneate below; their upper
