PHILIPPINE URTICACEAE, II. 303 
the cells often unequal, approximate at the base : pistillate receptacles 
unknown. 
Stems erect, 25 to 45 cm high, more often simple, or sparingly branched 
especially at the base, grooved, densely antrorsely grayish-strigose : leaves 
with petioles 5 to 8 mm long, similarly pubescent, lamina when dry 
subchartaceous or chartaceous, elliptic-oblanceolate or elliptic-obovate, 5.5 
to 10.5 cm long, 2 to 4 (usually 2.5 to 3) 'em wide, acute at the base on 
both sides or on the wider side obtuse, the margins dentate on both sides 
but not deeply, the teeth of the wider side from about 22 to 30, of the 
narrower 20 to 24, the apex except on reduced leaves definitely contracted 
into an acumen 5 to 15 mm, more often about 10 mm long; upper surface 
glabrous with numerous but inconspicuous cystoliths, under surface ap- 
pressed-strigose on the veins ; triplinefved, the nerves extending four-fifths 
the length of the lamina or often to the base of the acumen, other veins 
projecting on the under surface, on each side of the costa more often 3 
or 4 but with others of about equal number nearly as prominent, reticula- 
tions lax, conspicuous; stipules lanceolate to ovate, 2 to 2.5 mm long, 
acute, pubescent.

Merrill, ravines on banks of small stream at about 1,800 m elevation, Merrill 
1641- Among Philippine species, this has its closest alliance with that here 
identified 7 as E. longifolium Wedd., differing from it by the clustered staminate 
inflorescence, pubescence, leaf-bases and serration. It may also be near E. sessile 
var. punctatum Wedd., but the receptacles in the present case while numerous 
and often very small are each complete, whereas in the Indian plant, Weddell 
states that the fasciculate appearance of the (pistillate) receptacles is illusory, 
the receptacles being in reality deeply lobed. 8 In E. glomeratum, the elements 
of the receptacle are unusually loosely attached to one another.

Type, Cuming 456. 
Attention has previously been called to the Cuming specimen in this herbarium, 
and all identifications here have been based on the broad-leaved plant on our 
sheet. The difficulties are these. The name is inappropriate; the leaves are 
not elongate-lanceolate; those on our sheet are 27 to 37 mm wide; the base 
of the leaves can not be called acute ; the stipules are not long-persistent ; the 
staminate flowers are pentamerous instead of doubtfully tetramerous, there 
being little mechanical difficulty in ascertaining the fact. Most of all, I do not 
see why Weddell would not have made it a . variety of E. sessile , when he so 
treated E. ulmifolium Miq., which is a very near ally of the Philippine plant, 
to say nothing of E. brongniartianum Wedd., which is much further from E. 
sessile than is E. ulmifolium. This has led to the suspicion that this broad- 
leaved plant is really E. tomentosum Wedd., afterwards pla.ced by him next to 
E. ulmifolium, both as varieties of E. sessile. This is still conjecture, for although 
the botanists of Kew and Paris have most courteously searched their herbaria
