K. echinometra. KORTHALSIA. 115 
Description.—Slender. Sheathed stem 15-20 mm. in diameter. Leaf-sheaths 
armed with shcrt conical prickles. Ocreae inflate, elongate-elliptical or cymbiform, 
bluntish or apiculate, 7 to 10 em. long, 15-25 mm. broad, rigid-papyraceous, , 
cinnamon-brown and polished inside, armed with short scattered semi-conical 
horizontal prickles. Leaves of young plants non-cirriferous, ending in a flabellate 
bilobed leaflet, and having the side-leaflets .obsoletely or very briefly ansate ; the 
leaves of adult plants are cirriferousr have the petiole flattened-biconvex, 20 or 
more em. long, rather obtuse, usually smooth on the edges, armed beneath, along 
the centre, with a few solitary claws; rhachis in its intermediate portion armed 
almost regularly with ternate claws. Leaflets few, 4-5 on each side of the 
rhachis. alternate or subopposite, distinctly ansate, narrowly rhomboidal-cuneate, 
broadest above their middle, 15-20 cm. long, 4-5 em. broad. rather acutely 
praemorse-dentate in their upper margins, and produced at the apex into an 
acuminate point, green above, mealy-white beneath, and having 7 primary costae.

HanirrAT.—Mindanao ; District of Zamboanga (Herb. For. Bur. Manila No. 4816 ; 
Hutchinson, July, 1906). Nat. name “ Tanguguid” ; Agusan River, Butuan subprov. 
(Merrill No. 7313, Oct. 1910). Basilan Island (Hutchinson, No. 6106, Aug. 1906). 
OsservatIOns.—This is to all appearances the representative form in the 
Philippines of K. scaphigera, from which it differs in the much more elongate 
ant-harbouring ocreas, and in the leaves having the leaflets conspicuously mealy- 
white underneath. The ocreae in the Herbarium specimens show clear evidence 
of their having been inhabited by ants, for as in K. scaphtgera, they have a 
round hole or gate in their upper parts, and several narrow fissures at several 
points, probably for the admission of air into the lodging. 
PLate 67.—Korthalsia scaphigeroides Becc.—One non-cirriferous leaf, and 
another cirriferous from ‘the upper part of the plant. From Merrill's No. 7313 in

Derscription.—High scandent and rather slender. Sheathed stem 12—20 mm. in 
diameter ; the naked canes have a dull surface. Leaves elongate, those of the 
upper part of full grown plants about 1 m. long in the pinniferous part, and 
terminated by a clawed cirrus about as long or longer.  Leaf-sheaths short, more or 
less partially covered with a tobacco coloured scurf, almost entirely enwrapped by 
their ocreae, and in their short upper free part more or less spinous. Qereae. 
conspicuously inflate-cymbiform or elliptical, more or less elongate, at times ovoid,
