3. T. quadrifida, S onnerat ; A. DC. Prod. xvi. 2, 658. A tree 
20-30 feet high, with slender terete glabrous branchlets. Leaves 
opposite or casually subalternate ; petiole in. long ; blade obovate 
obtuse, cuneate at the base, 2-4 in. long, subcoriaceous, deep green 
above, paler green beneath, with fine just visible erecto-patent main 
veins. Flowers of both sexes varying from solitary in the axils of the 
leaves to 10 or 12 in a raceme half a foot long, rarely in cymes at the 
end of leafy branchlets. Pedicels shorter or not much longer than 
the flowers. Male perianth oblong, when unexpanded ^ to f in. long, 
gradually splitting into usually 4 long oblong-lanceolate lobes. Stamens 
with a short stout purple filament and a ligulate horizontal anther in. 
long. Female flowers oblong, the same size as the male, with 3-4 
short deltoid lobes. Accrescent female perianth as large as a 
potato, with a rough brown coriaceous cuticle, the crowded fruits half 
an inch long, only the style emergent from the mass of pulp.

mud. 
Mauritius, formerly frequent in the mountain-woods. Also Bourbon and 
Madagascar. I cannot by the descriptions separate from this T. neglecta and obovata , 
A. D.C. Prod. xvi. 2, 659 and 660. Tulasne attributes Bojer s synonym as cited above 
to T. Boivini, A. D.C. which has large acute coriaceous leaves with a rounded base 
and subsessile solitary axillary fruits. This is not known to me as a Mauritian plant, 
and our specimens from Bojer are T. quadrifida. Ambora racemosa, R. Brown, MSS. 
is a slight variety of this species with narrower (1-1§- in.) subacute leaves and 
smaller flowers. T. alternifolia, A.DC., may be a form of this with alternate 
leaves. Bois Tambour. 
4. T. peltata, Baker. Branchlets slender, glabrous, terete. Leaves 
opposite or alternate, obovate or oblong, obtuse or subacute, deltoid 
at the base, 2-3 in. long, pale green, with only the fine main veins 
distinctly visible; petiole f to 1 in. long. Flowers solitary from 
the nodes of the branchlets on pedicels under an inch long. Expanded 
male perianth lj in. broad, thin in texture, glabrous on the outside, 
with 4 deep lobes. Anthers ligulate, in. long, with a thick connec- 
tive and very short filament. Unexpanded female perianth depresso- 
globose, \ in. broad. Ambora peltata, B. Brown, Herb. 
Mauritius, Carmichael ! Endemic. 
5. T. elliptica, A. DC. Prod. xvi. 2, 660 ? Branchlets glabrous, 
terete or sometimes compressed and dilated near the top. Leaves oppo- 
site or casually subalternate, ob ovate-oblong, obtuse, cuneate at the 
base, the most coriaceous in texture of any of the species, bright green 
above, paler green beneath, with veins and venules distinctly visible, 
petiole J-f- in. long. Flowers solitary, on short pedicels. Expanded 
male perianth 2-2\ inches broad, glabrous, very thick in texture, 
splitting into 5-6 long irregular lobes. Stamens horizontal, densely 
imbricated, with ligulate anthers i n - long. Female perianth de- 
presso-globose, with a large open obscurely-lobed throat. 
Mauritius, on the shoulder of the Pouce, Capt. Carmichael ! Dr. At/res ! Also 
Bourbon, Boivin, but I have not seen the Bourbon plant, and its stamens are not 
known.
