lections are least typical. Bur. Sci. 76i) departing rather definitely from the type, 
but linking with it through some of the Bataan collections: Hur. Sci. 2^0 has 
both axillary and spicate glomerules, this also occuiriiig on the Lanao collection; 
they are otherwise quite typical. The stipules are decisive as separating this 
from /*. repandiis, which is otherwise quite distinct. 
Link's description, for a copy of which I am indebted to Lieut.-Col. Prain, 
is as follows: "Canle pubescente, foliis longe petiolatis ovate-Ianceolatis acu- 
minatis subcrenatis supra scabris subtus mollissime pubeseentiis trinerviis, floribus 
glomeratis axillaribus. Hab. in Manila T? C. Elegans species. Pet. 2-3' lougi. 
Folia lamina 5-6' longa 2' 2" lata. Nondum bene floruit." Plants suggested by 
the name are species of Laportea^ LeucosyTce^ and" Pipturus asper. The inflores- 
cence rules out the first, moreover Link obviously handled the leaves of living 
plants and his silence is significant: the glomerules of Leucosyke are peduncled, 
though shortly, and the petioles are always much shorter than the length given: 
to the identification with Pipturus aspcr, there are no obstacles. Blanco correctly 
interpreted Link's species, and Naves, in turn, figured the right plant as U. 
arhorescens Blanco. It is almost unbelievable that with its extreme distribution 
L 
in the Pliilippines, it should not have a wide range elsewhere, but the only other 
report is from Borneo.*" .

With all the variation in the leaves of P. arhoreacens, in shape, size, serration, 
and pubescence, this seems quite distinct, but the differences are somewhat difficult 
to define. The leaves of P. arhorescens vary in shape from lanceolate to nearly 
orbicular, becoming sometimes on plants from exposed situations nearly elliptic; 
those of P. mindmtaensis are elliptic, oblong, or sometimes elliptic-lanceolate; 
the margins of the former are often entire, but more often with very coarse teeth 
very slightly cutting the margin, where these are most nnnierous the number 
rarely roaches 30: in P. mindanaensis ^ the leaf is entire for about one-fourth of 
its length from the base, the teeth are numerous, about 45 or 50 on ordinary 
leaves, and not nearly as long across their bases a^ in the former: the petioles 
of P. mindanaensis range up to 18 mm in length, but arc usually distinctly 
shorter than this, whereas in P. arhorescens^ they are most often 4 to 5 cm 
long, but range all the way from 1.5 to at least 10.5 cm; they arc still 
shorter on reduced leaves which are often present upon normal plants or upon 
plants from exposed localities. These are the only two species of Pipturus with 
free stipules, their nearest ally, P. alhidtis (Hook. & Arn.) Wedd., having them 
nearly free. They are usually 3 to 4 mm long in P. arhorescens, ovate and 
narrowly acuminate, but are sometimes lanceolate and narrower and up to 7 
mm: in P. mindanaensis, they agree with the latter type. The parent species
