apex shortly and acutely acuminate j strongly 3-nei've(I, the nerves con- 
tinuing about six-sevenths of the length of the lamina, primary veins 
above the middle of the lamina, about 6 on each side, becoming ap- 
proximate at the apex, ,veins between midvein and nerves numerous, 
about twice as many as the stronger ones between the nerves and the 
margin, other venation comparatively inconspicuous ; upper surface 
densely covered with short stiff appressed hairs, the veins of the under 
surface with similar pubescence, the intervening portions very densely 
covered with very snowy tomentum; stipules ovate, amplexicaul, 7.5 
to 10 cm long, bifid at the apex for about 1 cm, acute, appressed-pubes- 
cent on the outer surface. 
Mindanao, Lake Lanao, Camp Iveithley, Mrs, Clemens s. n. More closely 
allied to L. candidissima than to any other species, but well distinct in the char- 
acters noted: its tomentum is much more snowy than in the only specimen of 
that species in this herbarium.

Arbuscula, ramulis tomento ferruginco et pilis albidis brevibus obteetis: 
foliis subcoriaceis, lanceolato-ovatis vel oblongo-ellipticis, basi acutis vel 
subrotundatis, margine ima basi excepta dentatis, apice acuminatis vel 
fere acutis, trinerviis; stipulis lanceolatis, 3 ad 5 cm longis : pedunculis 
pistilliferis longiusculis, capitulis majusculis, multifloris. 
Peduncles of pistillate capitula mostly in pairs, when mature 2 to 2.5 
cm long, the capitula 12 to 14 mm in diameter: flowers very numerous, 
subsessile, th^ perianth forming 5 very short obtuse or acuminate lobes; 
ovary flattened, obovoid, about 0.8 mm long; stigma capitate, very shortly 
penicillate. 
A tree 3 m higli, its stem 10 cm in diameter, the branchlets somewhat 
longitudinally ribbed, annulate and marked with the scars of fallen 
leaves, ferruginous-tonientose and with scattered white hairs more con- 
spicuous toward the apex and upon the petioles and the nerves of the 
under surface of the leaves, internodes variable in length: petioles 2 
to 4 cm long; lamina subcoriaceous, narrowly ovate or oblong-elliptic, 
18 to 21 cm long, 7 to 10 cm ^vide, the margins dentate except at the 
extreme base, the apex acuminate for about one-third the length or less 
or merely gradually contracted to an acute point, 3-nerved, the nerves 
extending about two-thirds the length of the lamina, additional primary 
veins 5 or more, veins between the midvein and the nerves numerou.s 
straight or nearly so for three-fifths or two-thirds of their length and 
then abruptly but obtusely bent down^\ard, usually but not always fork- 
ing at or near the bend, the veinlets slender but conspicuous bv their 
light-brown color against the white tomentum of the under sui-face, from 
which only the principal veins project; stipules submcmbranaceous, lan- 
ceolate, amplexicaul, 3 to 5 cm long, very shortly bifirl at the apex, their 
outer surface pubescent like the stem.
