6 mm latis, oblongo--ellipticis, obtusis et brevissime apiculatis, 
margine scariosis; acheniis anguste oblongo-obovoideis, teretibus, 
ossels, 5 mm. longis, acutis vel brevissime apiculatis. 
Caudex short, stout, about 1.5 em. in diameter. Leaves numer- 
ous, pale-grayish when dry, not very rigid, 1-nerved, about 85 cm. 
long, 2.5 to 3 cm. wide, slightly narrowed below, the basal part 
about 2 cm. wide, gradually narrowed upward to the long and 
slenderly caudate-acuminate apex, the margins and the midrib on 
the lower surface in the upper part serrulate. Scapes few, lateral, 
from the caudex below the leaves, up to 9 cm. long, 1.5 mm. in 
diameter, terete, the lower two to three cm. supphed with numerous 
mmbricate bracts, the bracts ovate to oblong-ovate, 1 to 1.5 cm. long. 
Inflorescences consisting of a single, solitary, spike-like head or 
sometimes of three separate, fascicled, similar heads, both types 
occuring on the same pilant, the indhiv idual heads terete, about 3 
em. long, 8 mm. in diameter, composed of numerous imbricate 
bracts, the bracts oblong-elliptic about 13 mm. long, 6 mm. wide, 
obtuse and very shortly apiculate, their margins scarious. Achenes 
bony, narrowly oblong-cbovoid, terete, erayish, about 5 mm. long, 
2 mm. in diameter, slightly narrowed below, the apex acute or very 
slightly apiculate. 
British North Borneo, Sandakan, Ramos 1854, December, 1920. 
In damp forests along small streams at low altitudes. This species 
is remarkable in the inflorescences. When the scape bears a single 
head, the head very strongly resembles that of Mapania humilis 
F.- Vill., but the same plant other scapes occur which bear three 
fasciculately arranged spikes at their apices. In leaf characters, 
however, the species is remote from VM. humilis. It is probably 
most closely allied to Mapania longa C. B. Clarke, but has much 
shorter scapes and broader leaves.
