Arborea, glabra, ramulis gracilibus teretibus, foliis oppositis breviter 
petiolatis oblongis acutis vel subobtusis rigide subcoriaceis utrinque viri- 
dibus venulis subtilibus immersis, floribus foemineis solitariis axillaribus 
globoso-turbinatis glabris breviter pedunculatis, fructu magno globoso 
carpellis confertis ovoideis. 
A small tree, with slender terete branchlets, glabrous in all its 
parts. Leaves opposite; petiole about 4 in. long ; blade 2-3 in. 
long, -1j in. broad at the middle, acute or obtuse, rounded or 
deltoid at the base, green on both surfaces, the main veins fine 
and immersed. Female flowers solitary from the axils of the

subglobose, 1 in. in diam., flat on the top, with a closed depressed 
umbilicate centre. Fruit a globe 14 in. in diam. when dried, brown 
and hard when unripe, with a black leathery pericarp when ripe, 
splitting down nearly to the base, the ovoid horny carpels 3 in. 
long covering all the face of the divisions.—Forests of Central

TAMBOURISSA TRICHOPHYLLA, n. Sp. 
Arborea, ramulis dense pilosis, foliis oppositis magnis breviter petiolatis 
oblongo-lanceolatis acutis basi rotundatis interdum prope apicem parce 
dentatis subcoriaceis facie obscure dorso dense pilosis, floribus foemineis 
globosis pilosis solitariis breviter pedunculatis. 
A tree, with slender terete woody branchlets, clothed towards 
the top with short dense grey hairs. Leaves opposite; petiole 
4-3 in. long, stout, pilose; blade 6-8 in. long, 13-2 in. broad, 
acute, rounded at the base, entire or furnished with a few deltoid 
teeth near the top, moderately firm in texture, dull green and 
rough with a few short bristly hairs above, pale and densely pilose 
beneath, especially on the raised midrib and few distant arcuate 
ascending main veins. Female flowers only seen, solitary, globose, 
on short peduncles from the axils either of young or full-grown 
leaves. Perianth } in. in diam., filled inside with the numerous 
ovoid glabrous brown ovaries, which are not at all immersed in 
the perianth.—Forests of Central Madagascar, Baron 1953 ! 
1975a! A plant labelled * Amboratseroka " by Dr. Parker is no 
doubt a nearly allied species. It has oblong obtuse coriaceous 
leaves 2-3 in. long densely hairy beneath.
