Flora of the Malayan Peninstda. 585 



The chief peculiarity of this species is in its pollen-masses being elongate and 

 having very small caudicles, and being therefore quite different from those of any other 

 species we have examined. The Perak specimens have no flowers, and can therefore 

 only be referred here tentatively, but we believe them to be correctly identified.

 rooting on the trunks and branches of trees and often pendent from 

 them ; stems glabrous or slightly pubescent, terete, lower ones as thick 

 as a goosequill. Leaves fleshy, coriaceous when dry, changing into 

 pitchers ; orbiculate or ovate-orbiculate, obtuse or mucronate some- 

 times acuminate at apex, rounded at base, slightly peltate ; both sur- 

 faces glabrous ; margins recurved ; -75 to 1 in. in diam. ; nerves faintly 

 visible beneath ; midrib slender ; main nerves about 3 to 4 pairs, the lowest 

 pair from the base and making an intramarginal nerve which the others 

 join; petiole stout, flat, '15 to '25 in. long, sometimes longer; pitchers 

 (ascicUa) 2 to 5 in. long, fleshy, thick, oblong or ovate-oblong, sHghtly 

 curved, obtuse, gibbous at base, the cavity filled with rootlets from the 

 adjoining node. Umbels about 6- to 8-flowered, small, rounded, on 

 a thickened tubercular rachis at the end of a long or short (iisually 

 •5 in. long) stout peduncle in the axil of the leaves ; pedicels 

 slender ; buds ovoid ; flowers pale yellow. Calyx membranous ; lobes 

 lanceolate, acute, ciliate, hirsute without. Corolla fleshy, urceolate ; 

 tube ovoid, pubescent without, -15 in. long ; lobes short, obtuse, villous 

 with somewhat retrorse stiff white hairs within, erect, -05 in. long. 

 Corona of 5 processes, attached to the base of the staminal-column, 

 each process on a stout base, deeply bilobed ; lobes spathulate, incurved. 

 Staminal-column short, conical ; anther-ceUs parallel ; appendages 

 acuminate, erect, membranous ; poUen-masses rather long, linear-oblong- 

 spathulate, seated on cup-shaped clavate brown caudicles, which attach 

 them to the oblong hardened dark poUen-carriers. Follicle 1, 2 to 

 8 in. long, cui-ved, -3 in. broad below the middle, tapering thence to 

 both ends ; pericarp thin, smooth. Seeds "1 in. long, somewhat angled, 

 oblong-obovate, narrowly winged on the margin, broadly winged and often 

 dentate at base, truncate at tip, bearing a silky coma 1 in. or more long ; 

 albumen very scanty ; cotyledons elliptic, obtuse, -025 in. long ; radicle 

 •5 in. long, cylindric. Griff'. Notul. lY. 47, t. 386, fig. 6, and in Trans.
