K. horrida]. KORTHALSIA. 117 
In a specimen from a plant cultivated in the Botanic Garden of Buitenzorg, 
under the name of Daemonorops ochreatus Teysm. the ocreae are very large, ovate, 
much inflated (4 cm. wide) and powerfully armed, but this specimen apparently 
was detached from the uppermost part of the stem, immediately below the 
terminal inflorescence, where, as in other spines, the ocreae are larger and 
broader than elsewhere. There is scarcely any doubt as to the identity of K. 
angustifolia B. gracilis Miq. with K. Echinometra; it was described from sterile 
specimens collected by De Vriese in Palembang (Sumatra), vernacular name “ Baku." 
PLATE 68.—Korthalsia Echinometra  Becc.—Intermediate portion of a plant 
showing two ocreae and a detached portion of the leaf belonging to it; from P. 
D. No. 1935.  Leaf-sheath and its ocrea and leaf from Scortechini’s No. 458b 
.in Herb. Beec. A separate ocrea, larger than usual, from a plant cultivated at 
Buitenzorg under the name of Daemonorops ochreatus. 
PLate 69.—Korthalsia Echinometra Bece.—Leaf and branch of the spadix with 
fruits not quite mature. From Hewitt's specimens in the Herbarium at Kew.

Description.—Rather slender. Sheathed stem 2 cm. in diameter. Leaves 
rather large ; one—apparently from a nearly fully grown but not yet fertile plant— 
is non-cirriferous, and 1°80 m. long. Leaf-sheaths, in their upper uncovered part 
and immediately below the insertion of the petiole, fugaciously and partially rusty 
furfuraceous and armed with straight, rigid, horizontal, 5-8 mm. long spines; 
on the sides the spines are flattened and ascendant; on the ventral side the 
leaf-sheaths are disintegrated into a fibrous net, but otherwise completely enveloped 
by their respective ocreae. Ocreae considerably inflated, 15 cm. long, 3 cm, 
broad, of a thin or papery-membranous texture, cymbiform or elongate—elliptical, 
armed all round with scattered, very slender and very sharp, elastic, laminar, - 
blackish spines, up to 12 cm. long, resting on a broad base, and spreading in 
every direction. Petiole thickish, slightly flattened, in one specimen 60 cm. long, 
8-9 mm. thick, armed all round with short, straight prickles; rhachis trigonous, 
slightly clawed below; the cirrus reduced to a very slender filament. Leaflets 
very numerous, 32 in all in one specimen, subopposite or alternate, elongate- 
lanceolate or lanceolate-ensiform, very gradually long-acuminate, rigid-papyraceous, 
very conspicuously  discolourous, being deep green above and white beneath, 
plicately 4-5-nerved; the main nerves spinulous on the upper surface; the lower 
margin of the apical part also spinulous; transverse veinlets very sharp on the 
upper surface; the medial and largest leaflets about 50 cm. long, 3-5 cm. broad; 
the upper ones gradually smaller and considerably shorter. The spadiz unknown. 
Hasirat.—Borneo. Known only from a specimen collected by me in June 1866 
on Mt. Mattang in Sarawak (P. B. No. 1918). Native name “ Rotang Sabakan.” 
Osservarions.—This also is known only from sterile specimens, but possibly 
represents only a young stage of K. Echinometra ; as the only leaf preserved belongs 
apparently to a not full grown plant. The ocreae are very much like those of 
K. Echinometra but of a thinner texture and the leaves have larger and more 
acuminate leaflets, with the main nerves abundantly spinulous on their upper
