Laportea mindanaensis Warb. in Perk. Frag. FI. Philip. (1903) 168. 
Mount Kinabalu, at 5,000 feet elevation, Eaviland 1222. This, referred by 
Stapf to L. stimulans Miq., is not typical of the above species, as the leaf-bases 
are more attenuate than is usual in Philippine material, and the venation is less 
arched, but some of our collections are nearly in agreement on the first of these 
characters and quite so on the second, while there seem to be no other differences. 
Laportea sp. 
Mount Kinabalu, Kadamaian, at 4,500 feet elevation, Haviland 1230. This is 
very close, to L. gracilipes Elmer, but the leaf -bases are very acute, the veins 
more numerous, and the lowest of them less prolonged. L. gracilipes seems to 
approach closer to L, stimulans than does any other Philippine species, but seems 
to be a much more glabrous plant with smaller leaves less numerously veined, 
laxer inflorescence, and slightly shorter bracts. 
Laportea sp. 
Mount Kinabalu, Penokok, at 3,000 feet elevation, Eaviland 1331, staminate, is 
probably the collection cited by Stapf as 131fl, as the locality and description 
entirely agree. This has some resemblance to L. anacardioides 0. B. Rob., but 
is not close to it, and is still further removed from, any other Philippine species. 
Laportea sp. 
Without locality, Garai 991, staminate, is quite distinct from any Philippine 
species, but resembles L. mindanaensis as much as any other. 
Laportea sp. 
Matang, at 2,000 feet elevaton, Eaviland 31/.6 ; Kuching. A third sheet, with- 
out attached data, might well be a duplicate of the first. This is vegetative'ly 
very similar to L. subclausa C. B. Rob., but has a very different pistillate in- 
florescence.

Pilea pterocaulis Stapf in Trans. Linn. Soc. Bot. II 4 (1894) 227. 
P. crassifolia Stapf 1. c. 228. 
These are represented by the type collections from Mount Kinabalu, Eaviland ' 
1229 and 1329, the latter noted on the sheet as not the number cited by Stapf, 
1339, and are valuable here for the means afforded to compare them with two 
Philippine species, P. benguetensis C. B. Rob. and P. intumescens G. B. Rob. P. 
benguetensis has much resemblance to P. crassifolia, but the stems of the former 
are less angled toward the apex and not at all near the base, the petioles are 
shorter, the lamina much more inequilateral, triplinerved instead of trinerved, 
these nerves are not at all exserted and paler in color, the nervules connecting 
the costa with the lateral nerves are even more delicate than in P. crassifolia, 
and the leaf-apices are more falcate. In spite of all this, the species are closely 
allied. 
P. intumescens has more superficial resemblance to P. pterocaulis, but is really 
much more widely separated from it than from P. crassifolia. From the former, 
it is distinguished by the shorter internodes, the more numerous ridges on the 
stem, absence of wings, longer petioles, and more serrate leaves. Compared with 
P. crassifolia, the internodes are of nearly equal length on the parts where direct 
comparison is possible, although shorter toward the base of the Philippine plant, 
the petioles of the latter seem stouter but in both cases give • evidence of having 
been succulent, and the difference may have been brought about in drying. But 
the thinner (at least when dry) lamina of P. intumescens is longer, nearly always
