that many supposed distinct species and varieties have been described. The extensive 

 series of specimens at Kew, and especially the copious illustrations particularly selected by 

 Dr. Welwitsch to show the amount of variation, amply suffice to show that these so-called 

 species merge one into the other, as even on the same plant characters belonging to two or 

 three of the established varieties may be met with. Dr. Welwitsch's testimony on this 

 point is emphatic. 



The most constant character, and one that runs through almost all the varieties, resides 

 in the small, globular, whitish-tomentose fruit, which is covered with comparatively stout 

 hooked bristles ; the white tomentum, however, is not always to be seen on the mature 

 capsules. One variety is stated to have clove-scented flowers. 



9. T. glechomoides, IFelw. mss. A trailing herbaceous plant, giving; 

 off numerous prostrate, slender, elongated, pilose branches, from a perennial 

 woody stock. Leafstalks short. Stipules subidate, ciliate. Leaves 1-3 in. 

 long, 1-H ill- wide, subcordate, ovate, acute, irregularly crenate-serrate, pal- 

 mately 3-7-nerved, with a few stellate hairs above and sludded with rather 

 coarse bristles along the nerves, coarsely stellate-pilose beneath. Flowers 

 numerous, in cymose clusters, placed at the extremities of the branches, in 

 leafless raceme-like groups. Pedicels shorter than the flowers. Flower-buds 

 oblong, apiculate. Flowers ^ in. and upwards in length. Sepals linear, 

 apiculate, violet. Petals oblong, tapering at the base ; the margins ciliate 

 below, shorter than the sepals. Stamens 10. Fruit globose, the size of a 

 small pea, 4-valved ; valves glabrous or nearly so, studded with short, stout, 

 conical, nearly smooth prickles, terminated by a fine -white, bent, scarcely 

 hooked point.

10. T. tomentosa, Bojer in Ann. Sc. Nat. Ser. 2. xx. 103. A shrub, 

 more or less densely covered with down, especially so along the petioles^and 

 under surface of the leaves. Leafstalks 1-2 in. long. Stipules lanceolate. 

 Leaves cordate or tapering at the base, oblong or ovate, sometimes 3-lobed 

 at the apex, lobes triangular, irregularly dentate ; 3-5 in. long, 2-3 in. wide. 

 Flowers numerous, arranged in small clusters opposite the leaves, along the 

 sides or at the ends of the branches. Pedicels y-1 in. in length. Flower- 

 buds oblong, obtuse, scarcely apiculate. Sepals oblong. Petals roundish, 

 stalked, yellow, ciliate at the margins below. Stamens 10, 5 long, 5 short 

 when in the bud, ultimately equal. Disk lobed, ciliate. Fruit the size of a 

 cherry, globular, covered with long, straight, black bristles slightly cibate 

 below. Capsule 4-valved, 4-seeded.

A shrub, generally about 5-6 ft. in height, cultivated in Mauritius and found wild also in 

 Madagascar and in India. It is nearly allied to, if indeed it be not the same plant as T. ovaia, 

 DC. Prod. i. 567. 



11. T, orthacantha, Welic. mss. An erect shrub with spreading pilose 

 brandies. Leafstalks very short, dilated upwards. Leaves 3-4 in. long, 1-1^ 

 in. wide, lanceolate, irregularly toothed, rough with simple hairs above, 

 densely stellate-pilose below. Flowers in small extra- axillary clusters along 

 the sides of the branches, forming an elongated, interrupted, leafless raceme. 

 Flow^er-buds oblong, apiculate, longer than the pedicels. Flowers less than 

 ■J in. long. Sepals linear-oblong, apiculate. * Petals oblong, shorter than the
