URTICACEAE FROM SARAWAK MUSEUM.

but shorter and less conspicuous cystoliths ; stipules orbicular- triangular, 
less than 1 mm long, caducous. 
Sarawak, Mount Koum, on limestone, Kalong 1721. Tlie species seems to find 
much its closest ally in P. rigida C. B. Rob., of northern Luzon, both appearing 
to be small plants with stems woody at least at the base, small and similar 
leaves, and greatly reduced pistillate inflorescences. But the stems of P. rigida 
are strongly angled while those of P. rigidiuscula are terete, the leaves of the 
former are much more definitely trinerved and their leaf-margins more 'sharply 
toothed. 
Pilea sp. 
Mount Kinaba'lu, at 5,000 feet elevation, Haviland 1305, staminate. This is 
probably an undescribed species in the alliance of P. melastomoides (Poir.) Wedd., 
but the staminate inflorescences are much shorter than the petioles, the petioles 
are very long, the leaves large and wider proportionately than on any of the 
Philippine plants referred to that species, the leaves are almost 5-nerved, but 
the outermost pair is very much more slender than the inner and prolonged less 
than one-third the length of the leaf. The specimen . hardly furnishes sufficient 
criteria of the comparative length of the petioles and size of the leaves. 
ELATOSTEM ATOI DES C. B. Rob. 
Elatostematoides sp. 
Niah, Haviland & Hose 3318. From its habit, this is almost certainly a 
species of this genus, but only staminate flowers are present, and there is no 
proof that it is not a Pellionia. The leaves are almost exactly the same as those 
of E. thibaudianum (Wedd.) C. B. Rob. (Elatostema rostratum Miq. non Hassk. ), 
but the inflorescence is very different, borne on long branching peduncles instead 
of being sessile. 
Elatostematoides sp. 
Rejang, Belaga, No. 2187, collector not named on label, staminate. This has 
much resemblance to E. robustum (Hallier f. ) C. B. Rob., differing in the larger, 
glabrous leaves, and the shorter stipules. It is probably an undescribed species, 
but is left with that status for the same reason as the preceding.

Procris pseudostrigosa Elmer Leafl. Philip. Bot. 1 (1908) 284. 
Kuching. Yery typical, a nearly perfect match for many Philippine collections. 
The species appears to find its closest alliance in P. frutescens (Bl.) Wedd. 
Philippines, Celebes. 
Procris ( ?) sp. 
Mount Kinabalu, at 3,500 feet elevation, Haviland 1773. Only staminate 
flowers are present, but the habit, the flowers and inflorescence, so far as they 
can, indicate the specimen to be of this genus, while it seems quite distinct from 
any published species. 
ELATOSTEMA Forst. 
Elatostema bulbothrix Stapf 1. c. 230, pi. XIX, fig. A, 1-1/. 
Mount Kinabalu, at 10,000 feet elevation, Haviland 1392, type collection. In 
discussing the affinities of this species, Stapf suggests that in spite of its well- 
marked differences from anything previously described it may come nearest to 
E. glaucescens Wedd. He described the receptacles as sessile, but evidently refers
