Inflorescentiis pistilliferis longis, pared ramosis, floribus in receptaculis 
dense stimuli!: eris, jam carnosis, subclausis, suffultis: foliis longe 
petiolatis, ehartaceis, oblongo-ellipticis vel late ellipticis, basi emarginatis, 
margine integris, apice acutis Vel acuminatis, saepe admodnm falcatis. 
Pistillate inflorescences purple, 25 to 35 cm long, sparingly branched, 
the rachis usually densely clothed with rather short stinging hairs: 
flowers sessile in pale-blue violet - or purple depressed-globose receptacles, 
which are densely clothed with stinging hairs and at anthesis already 
somewhat fleshy and except at the extreme apex closed over the flowers;' 
bracteoles lanceolate, acuminate, 3 mm long: perianth-segments 4, nar- 
rowly lanceolate, 1 mm long; ovary lanceolate, compressed, 0.8 mm long, 
tapering into a stigma of about equal length : fruiting receptacles up to 
1 cm in diameter ; achenes ovoid, compressed, nearly smooth. 
A shrub 1 to 3 high: leaves with petioles 6.5 to 23.5 cm long, the 
chartaceous lamina oblong-elliptic or broadly elliptic, 25 to 53 cm long, 
7 to 23 cm wide; the base emarginafe or subpeltate, the apex gradually 
narrowed to an acute point or somewhat acuminate, often slightly falcate ; 
lateral veins on each side of the 'midrib 12 to 15, strongly ascending, 
arched or nearly straight ; upper surface of lamina glabrous, under surface 
tomentellose ; stipules ( ? ) broadly lanceolate, 2 cm long.

Inflorescentiis staminiferis paniculato-cymosis, parce puberulis, 5 ad 
8 cm longis, pedunculo 2 ad 3 cm longo, floribus in glomerulis haud 
eonfluentibus dispositis, tetrameris, perianthii lobis late lanceolatis, 2 ad 
2.5 mm longis, obtuse acuminatis, ovarii rudiment®, stipitato, subgloboso, 
0.7 mm longo : arbor, foliis alternis, modice petiolatis, laminis ehartaceis 
saepe obliquis, ovatis, ellipticis, vel oblongo-lanceolatis, 10 ad 22 cm 
longis, 4.5 ad 9 cm latis, basi subpeltata rotundatis vel angustatis truncat- 
isque, margine admodum revoluta subintegris, apice breviuseule acuteque 
acuminatis; venis utrinque 7 ad 9 cum reticulatione conspicuis; stipulis 
ovatis, caudatis, dense pubeseentibus. ■

The absence of pistillate flowers prevents the inclusion of this species in the 
key, but it seems closely allied to L. luzonensis, differing from it in the much 
more- conspicuous leaf-venation, the greater protraction of the basal veins and 
the more densely pubescent stipules. There are probably other undesefibed species 
in this herbarium, as yet unrepresented by pistillate material.
