PHILIPPINE URTICACEAE.

Elatostema obovatum Wedd. in Ann. Sci. Nat. Bot. IV 1 (1854) 190. 
Luzon, Province of Laguna, Calauan, Bur. Sci. 12370 McGregor. This collec- 
tion is an excellent match for Cuming 628, from the same locality. Staminate 
receptacles are still wanting, but there is little doubt that it has been placed in 
the correct alliance, as shown by its similarity to E. delicatuium Wedd., also 
represented by "Bur. Sci. 12361 McGregor, Calauan, and to E. glaucescens Wedd., 
also represented by Bur. Sci. 12334 McGregor, Calauan. 
Elatostema viridescens Elmer Lead. Philip. Bot. 1 (1908) 285. 
Luzon, Province of Benguet, Baguio, Bur. Sci. 12752 FSnix. The specimens 
are sterile, and have smaller leaves and shorter stipules than the more southern 
collections, but are otherwise very similar. 
Elatostema hookerianum Wedd. in Arch. Mus. Paris 9 (1857) 309. 
R. E. Cooper 692, Sikkim, suggests an alliance for E. apoense Elmer, but at 
least the young staminate bracts are more corniculate, the plants glabrous, and 
the leaves smaller and of somewhat different outline and texture than in the 
Apo plants. 
Elatostema obtusiusculum C. B. Rob. 1. c. 537. 
Luzon, Province of Benguet, Sablan, Bur. Sci. 12755 Fenix. As critical col- 
lections as could be desired to test the validity of two of the species proposed 
as new have been obtained, and the one just cited has distinctly smaller leaves 
than the type with a corresponding decrease in the number of marginal teeth, 
bringing it close in both these respects to E. irongniartianum Wedd. This makes 
the characters stated in my key insufficient for certain determination, but still 
suggestive; those in the text, drawn from venation and pubescence, seem quite 
reliable. 
Elatostema plumbeum C. B. Rob. 1. c. 535. 
Luzon, Province of Benguet, Baguio, Bur. Sci. 12757 Fenix. Again, the leaves 
are smaller than in the type, and the smaller ones can hardly be called distinctly 
acuminate. With these qualifications, the species still seems distinct and to be 
separable as previously noted. 
Elatostema variegatum C. B. Rob. 1. c. 538. 
Luzon, Province of Benguet, Sablan, Bur. Sci. 12756 Fdnix. 
Elatostema sp. 
Luzon, Province of Benguet, Sablan, Bur. Sci. 12753 Fenix. This differs from 
any Philippine or other species with which I am acquainted, but is left un- 
described, as no staminate receptacles are present, and the alliance, although 
probably with E. longipedunculatum Elmer, is not obvious. 
PROCRIS Commers. 
Procris lagunensis C. B. Rob. 1. c. 506. 
Philippines, without further locality, Loher 6945. The leaves are somewhat 
narrower than the type, and render the validity of the species increasingly 
doubtful.
