Calyx cup-shaped, 5-toothed or 5-fid, persistent. Petals 5, oblanceolate- 

 linear'or spathulate, imbricate. Stamens 10, monadelphous. Anthers ob- 

 long or linear, apiculate, inserted in the mouth of the staminal-tube, included 

 or exserted. Ovary 5-12-(20-)celled. Capsule with 5 or more cells, coria- 

 ceous or somewhat fleshy at first, globose or clavate. — Trees or shrubs. 

 Leaves simple, alternate, petiolate, entire or lobulate. Flowers axillary, pe- 

 dunculate or pedicellate, fasciculate umbellate or solitary. 



A genus confined to the tropics of the Old World, the following' species to the African 

 continent. 



Leaves, some at least, obovate-enncate, 3-lobate above. 



Flowers solitary or in pairs, axillary \. T. heterophglla. 



Leaves elliptical, entire, apiculate or acuminate, glabrate. Umbels 

 2-oo-flowered ; pedunculate. Stamiual teeth subulate. Ovary 

 9-12-celled 2. T. Vogelii. 



Leaves elliptical, narrowed to each end, thinly pubescent beneath. 

 Peduncles 2-4-flowercd. Staminal tube crenate or entire. Ovary 

 5-celled 3. T. abgssmica. 



Leaves obovate obtuse, tomentose beneath. Uinbellnte many-flowered 

 fascicles sessile. Staminal teeth triangular or oblong, entire or 2- 

 fid. Ovary 10-celled 4. T. nilulka. 



Leaves oblanceolate or rhomboidal, entire or lobulate. Flowers soli- 

 tary or 2 or 3. Staminal tube fimbriate. Ovary 5 -celled . . . 5. T. obtusifolia. 



1. T. heterophylla, Sm. ; DC. Prod. i. 620. Leaves thinly membra- 

 nous, usually more or less obovatc-cuneate, 3-lobate above, with rectangular 

 or obscure lateral lobes above the middle or varying to broadly obovate-ob- 

 long, subentire, obsoletely pubescent at least on the midrib below, 2-2£ in. 

 long, 1-1J in. broad; petiole 2 lines. Flowers |-| in. long, solitary or in 

 pairs from the upper axils, on peduncles of \-\ in. Calyx-teeth deltoid. 

 Teeth of staminal tube apparently capillary. Ovary . . . ? 



Upper Guinea. Cape Coast, Brass ! Afzeluis ! 



Dr. Lindley in the ' Botanical Register' (xxx. t. 4) figures and describes a plant brought 

 from Sierra Leone by Whitfield, utider the name T. lobata, which is probably identical with 

 the above. The ovary he states to be certainly 5-celled, while T. heterophgll'a is disposed by 

 Mr. Bennett (Plants; Javan. Bar. 184) under the section of the genus characterized by a 10- 

 20-celled ovary. In other respects the resemblance between Dr. Lindley's figure and Smith's 

 plant is very close. In T. lobata the teeth of the staminal tube are 20*in number, subulate, 

 and arranged in 10 pairs. T. quercifotia, Don, Gen. Syst. i. 678, may be also cited as a 

 synonym. Dr. Sonder, in ' Flora Capensis ' (i. 245), identifies a Cape Tnrraa (T. flori- 

 bttnda, Hochst.) with Smith's plant, but I think he is mistaken. 



2. T. Vogelii, Hook.f. Fl. Nigrit. 253. A shrub or small tree, often 

 with elongate, rather slender, pubescent or glabrate branches. Leaves mem- 

 branous, oblong-elliptical or broadly elliptical, shortly acuminate, more or less 

 rounded or cuneate at the base, entire, glabrous excepting the midrib and 

 principal veins, which are often puberulous or with hairy tufts at the axils; 

 2|-5 in. long, l|-2f in. broad; petiole 2-3 lines. Flowers on axillary pe- 

 duncles, usually from £ -2| in. long, bearing from 2-8 or 10 umbellate
