distinctly the longest, especially on the narrower side of the leaves. Iiallier’s 
specimen of E. paluclosum is much more pubescent than his of E. macrophyllum, 
but from Miquel’s description the leaves of the former are more pubescent than 
those of the type of the species. 6 The leaves of E. Icigunense also vary in 
pubescence, but in that species the explanation in at least some cases is humidity 
and not age. The stipules of E. macrophyllum are 3 mm long, those of E. 
paludosum only 1 mm long. The staminate receptables of E. lagunense are 
usually much larger than those of E. paludosum are said to be by Miquel, 
but they must vary in this respect with age, and this difference would have 
to be verified by very full collections before it could be used as a positively 
discriminating character. 
Perhaps the closest leaf-similarity of all between E. lithoneurum and any 
Philippine species, is with one from Mount Tonglon, Benguet, Phil. PI. 812 
Merrill, which will be described as new, 7 but the Benguet plants have not only 
densely pubescent stems but the staminate receptacles are either shortly and 
stoutly peduncled or subsessile. 
Elatostema thal ictroides Stapf 1. c. 229, pi. XIX, fig. B, 5-8. 
Mount Kinabalu, at 5,000 feet elevation, Eaviland 1219. As already surmised, 8 
this is a very real alliance for E. halconense C. B. Rob., but the latter is a 
coarser plant with stems and branches of a yellowish or grayish color, while 
those of E. thalictroides are rather dark-reddish. Except for the ultimate 
branchlets, which are very densely pubescent in both species, E. halconense is 
distinctly the more pubescent. The leaves are of different outline, longer and 
narrower in E. halconense, with the apical tooth much farther prolonged. E. 
suhlignosum C. B. Rob. and E. baruringense Elmer are progressively more dis- 
tinct from E. thalictroides than is E. halconense. E. podophyllum Wedd., 
although having leaves with a distinctive base and outline, is also in the same 
alliance. 
Elatostema sp. 
Niah, Eaviland & Rose 3817, with pistillate receptacles which although very 
young are sufficient for positive generic determination. The alliance is probably 
with E. procridioides Wedd., but no staminate receptacles are present, making 
a positive statement impossible. 
Elatostema sp. 
Mount Braang, on limestone, Eaviland 637 , also without staminate receptacles. 
It has much the appearance of being a reduced state of E. lusonense C. B. Rob., 
but with this difference, that when the leaves of that species become reduced 
they take on a different form either from those of better developed plants of 
the same species or of those of the Bornean collection. There are no opposing 
leaves of smaller size than the others, the characteristic of E. surculosum Wight, 
and the leaves are smaller than those of E. siklcimense C. B. Clarke, resembling 
rather -those of E. glaucescens Wedd., a species which differs in pubescence and 
in various other ways.
