Cuming 629 was a mixture, and both species under which it was cited are 
represented on the sheet in this herbarium. From Weddell’s key, they might 
be expected to differ in the leaf-apex, but in this they are very similar, the dis- 
tinguishing characters given in the description being the eystoliths and the color 
of the leaves. The other collections here cited are good matches for the cotype, 
some having rather larger leaves, others narrower ones: the longest leaf on the 
cotype is 2 cm long, on any other 3.5 cm; the greatest width is 14 mm. This is 
almost sufficient in itself to justify a separation from a species with leaves 5 to 
15 em long, 2.5 to 6 em wide, but there are additional characters. An apical leaf- 
tooth is present, as in almost every other species of the genus, this but rarely 
and then barely projects beyond the general outline of the leaf, whereas in the 
7 sheets in this herbarium from Java and India, of EF. sessile and species referred 
to it as varieties by Weddell, the apex is always very distinctly acuminate. The 
Philippine plants are also more pubescent, and the lateral veins are usually 3 or 
4 on the wider side of the leaves. For the identification of 2. sessile var. minus, 
I am indebted to Dr. F. Gagnepain, of the Muséum d’Histoire Naturelle, Paris, 
who writes that the labels on the sheets in that herbarium are so changed, in 
Weddell’s own handwriting. 1 
Weddell attributes this species to India and Australia also; there is no ref- 
erence to it in Flora Australiensis: the Indian plant was FE. reptans Hook. f.* 
36. Elatostema variegatum sp. noy. 
Receptaculis pistilliferis sessilibus, bracteis omnibus  subsimilibus, 
oblongo-lanceolatis: suberectum, caulibus dense pubescentibus; foliis 
membranaceis, variegatis, oblique oblanceolatis ad obovatis, apice haud 
vel vix acuminatis, triplinerviis, stipulis anguste oblongis, apiculatis, 3 
mm longis. 
Pistillate receptacles sessile, about 4 mm in diameter; bracts more or 
less fused at the base, the outer similar to the others, oblong-lanceolate, 1 
mm or slightly more in length, ciliate, not or barely corniculate ; bracteoles 
narrowly oblong-oblanceolate, slightly over 1 mm long, densely pilose 
at the apex; perianth typical; achenes ellipsoid, about 0.5 mm long, pale 
with faint brown longitudinal lines. 
Nearly erect from a creeping base, 8 to 12 cm high, the stems very 
densely covered with cinereous and fulvous substrigose spreading pubes- 
cence: leaves very shortly petioled or subsessile, the lamina membrana- 
ceous, beautifully variegated when fresh with light- and dark-green, less 
conspicuously so when dried, oblanceolate to obovate, 12 to 36 mm long, 
8 to 12 mm wide, with other reduced leaves, the base acute or subobtuse
