from the costa at or very near the insertion of the petiole, but the upper 
pair no longer and the lower pair shorter than all except the apical of the 
succeeding 13 to 16 pairs, these veins uniting to from a definite arched 
submarginal vein, secondary veins numerous and conspicuous; stipules 
lanceolate, 3.8 to 4 cm long, 9 to 12 mm wide, acuminate at the apex, 
truncate at the base, entire or near the apex denticulate, purplish within, 
tomentose without, sometimes membranaceous-winged. 
Mindanao, District of Davao, Santa Cruz, Williams 2883. Very distinct 
among Philippine species, but closely allied to F. conspicdbilis King, from which 
it differs in the shape of the receptacles, and the more cordate leaves with more 
numerous veins. 
Local name (Bagobo) : maidong.

Additional results of the dissection of staminate flowers of this genus 
are here given. It is unfortunate that so few pentamerous species are 
represented by sufficient material to justify dissection on a large scale. 
So far as this has been possible, they have been equally constant. The 
39 flowers counted of E. delicatulum were all that could be obtained from 
24 receptacles, taken from 12 different plants.

This has a close ally in E. obliquifolium Reehinger, 1 of Samoa, as represented 
by Vaupel 209. The leaves of E. obliquifolium are distinctly more redu'ced on 
the narrower side than are those of E. acrophilum, the upper surface has more 
conspicuous cystoliths, the veins of the under surface are pubescent, the marginal 
teeth are less coarse, and the veins are closer, the stem also is more pubescent. 
In some of these respects, E. obliquifolium comes closer to E. microphyllum 
Elmer, but that species has much less oblique leaves.

Urtica arborea Luzonis Camel ex Ray Hist. PI. 3 (1704) App. 70. 
Camel’s description leaves little doubt that this is the species intended, at 
least in the main. Its undoubted stinging qualities and its alleged medicinal 
properties are mentioned. Two of the local names given by him, lipa and lipay
