Descriptive Notes 07i Papuan Plants. 
hair ] leaves large, ^fixed at the basal extremity, co^^date-orbieulate, cleft 
to one-third or less into three lobes, above almost g-labroixs, beneath 
short-pubescent and conspersed with very minute glands, the three 
primary nerves arising from the base of the leaves ; capsules three-celled, 
glandular-pulverulent and beset with rather long hardly rigid echinular 
excrescences. 
On the Fly-River ; Rev, S. Macfarlane. 
Branchlets thick, distantly marked by the annular scars left by the 
stipules. The latter nearly 3 inches long, reminding of those of many 
Ficua-species, consisting of a single piece, membranous in texture. 
Leaves on rather long cylindrical strong petioles, so far as seen from a 
span to a foot long and nearly as broad, irrespective of the two anterior 
incisions only minutely denticulate, above shining, beneath opaque ; 
their primary as well as the pinnately disj)osed secondary nerves very 
prominent beneath ; their primary veins parallel, transverse and beneath 
also prominulous ; the secondary veins parallel-longitudinal, connected 
by reticulating veinlets, thus the main-venation rendered almost can- 
cellate. Flowers unknown. Fruits with turgid cells, nearly half an 
inch high j the endocarp seceding. Seeds roundish, somewhat verru- 
cular, without any arillus ; testa crustaceous ; embryo and albumen not 
observable in the obtained seeds. 
The large stipules place this species near M. stipulosa, M. hispida and 
M. longistipulata. From the first of these three our plant ditfers ah-eady 
in the basifixed therefore not peltate leaves ; from M. hispida, according 
to a typic specimen kindly sent by Mr. S. Kurz, M. aleuritoides is easily 
separated by the closely downy and hairy branchlets petioles and pe- 
duncles, by the beneath pale and not almost glabrous but lobed leaves, 
with more prominent veins, yet without any very visible and copious 
glandular impressions, and with a far less waved margin, also by the 
more hairy fruit with thicker excrescences. Ag'ain from M. lotigistipulata 
the new Papuan species recedes on account of its stout branchlets, its 
long stalked not strictly penni-nerved but rather palmati-nerved leaves, 
which moreover so far as known are never lobeless, nor ovate-lanceolar, 
nor beneath densely impressed with glands, and further in capsules 
much larger than those described of M. longistipulata. The structure 
of the flowers, when they become known, will likely reveal further 
diagnostic diflerences yet, to distinguish this from the several allied 
species.
