 branous, glabrous above, sparingly hairy on the nerves and gland-dotted

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 M. kilimandscJiarica, are siif;liLly peltate ; the leaves 

 of Englei- 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 

 distinctly acuminate, while the stipules are larger. Da we 602, from Ruwenzori at 

 €000-7000 ft., has equally peltate leaves, but with a less acujninate apex, entire 

 marg'ins and firmer consistence then in Mildbraed 2701. Two sjiecimens from 

 iirerman 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, tiiose of 294 are less markedly peltate and less markedly denticulate. 

 Still another specimen, with very widely peltate leaves, is Lyne 101 from ihe Ngazi 

 forest, Pemba. Unfortunately all the specimens here alluded to — which may repre- 

 sent three (if not four) distinct but allied species — agree with M. rmcenzorica in 

 Laving neither flowers nor fruit. 



10. M. kilimandscharica. Pax in Engl. Pfl. Ost-Afr. C. 2r>8. 

 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. in diam. —

SchwernfurtlH 3337. f »oni Yntu, Niamnium, is nearly allied to, if not a form of, 

 this species. The leaves are rather narrower for their length and are borne on long 

 slender shoots arn;ed with numerous spines.
