9. M. ruwenzorica, Pax in Engl. Jahrb. xliii. 322. A tree; 
branches at first pubescent, soon glabrous. Leaves long-petioled, rather 
broadly peltate, triangular, caudate-acuminate, base truncate or slightly 
retuse, margin denticulate, 5-10 in. long, nearly as wide, thinly mew- 
branous, glabrous above, sparingly hairy on the nerves and gland-dotted 
beneath ; petiole 4-6 in. long; stipules lanceolate, }-} in. long. Flowers 
and fruit unknown.

Described by Dr. Pax from imperfect material because of its being the first 
African Macaranga with peltate leaves. This is not exactly the case; the leaves of 
Volkens 1271, included by Pax in W, kilimandscharica, are siightly peltate ; the leaves 
of Engler 648, from Nguelo, East Usambara, are nearly as peltate as those of Mildbraed 
2701 and are similar in consistence, but are less markedly denticulate and less 
distinetly acuminate, while the stipules are larger. Dawe 602, from Ruwenzori at 
6000-7000 ft., has equally peltate leaves, but with a less acuminate apex, entire 
margins and firmer consistence then in Mildbraed 2701. Two specimens from 
German East Africa, named “Mkumba” and numbered 294 and 326 in Berlin 
Herb., appear closely related to Engler 648, but those of 326 are firmer and not 
peltate, those of 294 are less markedly peltate and less markedly denticulate. 
Still another specimen, with very widely peltate leaves, is Lyne 101 from the Ngazi 
forest, Pemba. Unfortunately all the specimens here alluded to—which may repre- 
sent three (if not four) distinct but allied species—agree with WM. ruwenzorica m 
having neither flowers nor fruit. 
10. M. kilimandscharica, Pux in Engl. Pf. Ost-Afr. C. 238. 
A tree; young branches pubescent. Leaves long-petioled, often nar- 
rowly but distinctly peltate, wide-ovate, acute, base rounded or slightly 
cordate, margin entire, 4—6 in. long, nearly as wide, subcoriaceous, 
_ glabrous; petiole 3—4 in. long; stipules lanceolate, deciduous. Male 
flowers in short lateral panicles ; bracts ovate, acute, entire, subtending 
several flowers. Stamens 2. Female flowers in short axillary panicles ; 
bracts as in the males. Calyx-lobes ovate. Ovary glabrous, 2-celled ; 
stigmas recurved. Capsule globose, densely lepidote, } in. diam.—

Schweinfurth, 3337, from Yuru, Niamniam, is uearly allied to, if not a form of, 
this species. The leaves are rather narrower for their jength and are borne on long 
slender shoots armed with numerous spines.
