5. Laportea batanensis sp. nov. 
Floribus pistilliferis in receptaculis flabellatis fructu valde auctis 
suffultis: foliis membranaceis, inaequilateralibus, ellipticis, ovalibus, vel 
oblongo-obovatis, basi truncatis vel rotundatis, emarginatis, margine 
integris, apice acuminatis. 
Pistillate inflorescences 7 to 22 cm long, widely branching, pubescent 
especially on the younger branches : flowers sessile along the distal margin 
of a flattened flabellate receptacle 1 to 1.5 mm wide, 5 to 10 on each, the 
pedicels of the receptacles less than 1 mm long, bracteoles lanceolate, less 
than 1 mm long, inconspicuous: perianth-segments 4, lanceolate, 0.6 mm 
long, nearly equal; ovary 0.6 mm long, slightl¥ oblique and ventricose ; 
stigma 1.5 mm long, pubescent, often flattened and dilated distally: 
width of fruiting receptacles ranging to more than 1 em, the achenes no 
longer marginal, compressed, obliquely suborbicular, 3 mm long, ventri- 
cose, strongly and coarsely tuberculate : staminate inflorescence unknown. 
A tree 5 to 7 m high, its stem about 15 cm in diameter, glaucescent 
and glabrescent at the apex: leaves with pubescent petioles 1 to 4 cm long, 
the membranaceous lamina elliptic, oval, or oblong-obovate, 9 to 19 cm 
long, 5 to 12 cm wide, the base rounded or truncate, emarginate, the 
margins entire, gradually narrowed and acuminate ; lateral veins on each 
side of the midrib 9 to 13, arched-ascending, the veins of the lower sur- 
face more or less pubescent, especially when young ; stipules ovate, acute 
or acutely acuminate, 8 mm long.

Fénivx. Noted as very poisonous. 
Among Philippine species, this most closely approaches the next, from which 
its greatly enlarged fruiting receptacles seem to separate it: it is difficult to 
distinguish it, upon the floral characters given by Weddell, from his L. ptero- 
stigma, of Formosa, but the description of the leaves in texture, shape, and 
pubescence, make such an identification at least temporarily impossible.
