6171. The second collection cited from Mount Binuang, collected, at an elevation 
of 9Q0 m, has some of the leaves quite entire. The Mindoro distribution is to 
be noted, as it is only one of several cases that have been made evident by 
recent explorations. Probably all three Banajao collections were from the same 
mountain. 
The pistillate receptacles are now known: it may be sufficient to say that 
they are sessile, of small size, and conform in all respects to the general type 
of the genus : the staminate flowers are 4- or 5-merous.

39. Elatostema halconense sp. nov. 
Receptaculis pistilliferis sessilibus ; bracteis exterioribus subliberis lan- , 
ceolatis, haud acuminatis : lignosum, ramis apicem versus dense pubes- 
centibus ; foliis membranaeeis, oblanceolatis vel anguste elliptieis, mar- 
gine utroque latere dentibus saepissime duobus gerentibus, apice con- 
spicue acuminatis. 
Pistillate receptacles sessile, small; outer, bracts free nearly to base, 
lanceolate, about 1.5 mm long, barely or not corniculate, densely pilose 
and ciliate; inner bracts similar but narrower; bracteoles linear-oblan- 
ceolate, densely pilose at the apex; flowers shortly pedicellate; perianth 
minute, 3-lobed, more or less ciliate; ovary ovoid, about 0.4 mm long; 
stigma penicillate-villose. 
Erect, 30 to 70 cm high, the stems woody, much branched except near 
the base, the branches and the upper part of the stem covered with dense 
somewhat appressed pubescence; leaves sessile or 'subsessile, the lamina 
membranaceous, oblanceolate or, narrowly elliptic, 15 to 32 mm long, 
5 to 10 mm wide, base of the narrower side acute, of the somewhat wider 
obtuse or very shortly auriculate, the basal half or two-thirds of the 
margins entire, then with usually 2 acute or obtuse teeth on each side, 
the acumen narrowly lanceolate, 5 to 13 mm long, acute, apiculate; the 
glabrous olivaceous upper surface with numerous cystoliths, under sur ■ 
face paler, appressed-pubescent on the veins, without conspicuous cys-
