40. Elatostema sublignosum sp. nov. 
E. haleonensi affine, sed cliffert foliis longioribus, magis dentatis, caule 
ramisque densius pubescentibus. 
Pistillate receptacles sessile, 2 to 3 mm in diameter : outer pair of 
bracts ovate, 1.5 mm long, obliquely short-corniculate, ciliate, pilose; 
other bracts narrowly oblong, otherwise similar; bracteoles linear-oblan- 
eeolate, 1.5 mm long, long-pilose; flowers shortly pedicellate; perianth 
about 0.1 mm long, 3-lobed; ovary -elliptic, compressed, about 0.4 mm 
long; stigma penicillate-villose. 
Erect, woody, especially as seen in dried material, 40 to 70 cm* high, 
widely branching, the branches and the upper part of the stem densely 
covered with dirty-yellowish somewhat spreading pubescence: leaves ses- 
sile or subsessile, the lamina membranaceous, obliquely oblanceolate to 
elliptic, 1.5 to 13.5 cm long, 5 to 32 mm wide, the base of the narrower 
side acute or more often subobtuse, that of the wider rounded or very 
shortly auriculate, teeth of the wider side 3 to 6, of the- narrower 2 to 5, 
most often 3, the acumen lanceolate, 7 to 35 mm long, acute or subacute; 
upper surface glabrous with very numerous eystoliths, the under fulvous- 
pilose ; triplinerved, with 3 or 4 additional veins ; stipules lanceolate, 2 
to 4 mm long.

This and the two preceding species are very closely allied, possibly having 
their nearest alliance among previously described species in E. integrifolium 
Wedd., from "which the stipules and still more the details of structure of the 
staminate flowers keep them quite distinct. When compared with one another, 
it is equally obvious that they are very similar and yet not identical, but with 
the differences of such a nature that additional collections may serve to unite
