This species belongs in the group Avith Elatostema obovatifolia 
Wedd. and in many characters is similar to Elatostema elmeri 
nom. nov. (E. pictum Elm., non Hallier f.), from which it is 
easily distinguished by its appressed-hirsute branches, nerves, 
and reticulations on the lower surface of the leaves ; Elatostema 
elmeri is glabrous. 
ELATOSTEMA MACGREGORII sp. nov. 
Herba prostrata, usque ad 16 cm longa, ramis et subtus folds 
ad costa nervisque perspicue hirsutis; folds subsessilibus, obo- 
vatis ad oblongo-obovatis, 6 to 12 mm longis, inaequilateralibus 
basi leviter oblique cordatis, dentibus in partibus superioribus 
4 vel 5, conspicuis ; inflorescentiis $ tenuiter pedunculatis, brac- 
teis exterioribus late ovatis, corniculatis, 5 sessilibus, bracteolis 
perspicue ciliatis; floribus, 4-meris. 
A slender, prostrate or somewhat ascending, simple or spar- 
ingly branched herb, the stems 16 cm long or less, the latter 
with scattered, ascending or somewhat spreading, hirsute hairs. 
Leaves green when dry, sessile or subsessile, obovate to oblong-* 
obovate, inequilateral, 6 to 12 mm long, 5 to 8 mm wide, the 
apex obtuse to subacute, the apical part with 4 or 5 conspicuous, 
usually rounded teeth, the margins in the lower two-thirds to 
three-fourths entire, base rounded-auriculate on the broader side, 
obtuse on the narrower side, somewhat obliquely cordate, the 
upper surface glabrous and with scattered cystoliths, the lower 
surface somewhat appressed-hirsute on the midrib and nerves, 
the latter 2, rarely 3, on each side of the midrib, the cystoliths 
obsolete ; stipules membranaceous, oblong, glabrous, about 2 mm 
long. Staminate receptacles axillary, solitary, 4 to 5 mm in 
diameter, their peduncles slender, glabrous, 1 to 2 cm long ; outer 
bracts broadly ovate, about 4 mm long and wide, the apex rounded 
or retuse, prominently keeled and corniculate, the apiculus about 
1.2 mm long, glabrous or nearly so, the inner bracts oblong-ovate, 
somewhat ciliate; bracteoles spatulate, sparingly ciliate, 3 mm 
long. Flowers 4-merous, shortly pedicelled. Sepals oblong to 
oblong-elliptic, 1.5 mm long, two slightly cucullate and minutely 
apiculate, usually with a few long ciliate hairs above. Pistillate 
inflorescences sessile, densely many-flowered, about 4 mm in dia-
