and Billiton only the following are known: Jambosa buxijolia, 

 Syzygium variifolium, Tristania obovata, Schima bancana, Xyris 

 bancana and Lindernia (Vandellia) stemodioides ; Oratoxylum glaucum 



and a Lucinaea spec, nova were only known from Borneo. The 

 as yet undetermined Eugenia, Nepenthes, Dischidia and Ischaemum, 

 and a few others, are doubtful in this respect. 



Endemic, as far as our present knowledge extends, is only the 

 new species, now to be described. Unfortunately data are wanting 

 about the dimensions and habit of this plant, but it belongs to the 

 suffructicose inhabitants of the low sand-padangs, referred to above; 

 it is among the species, poor in individuals, and it reaches a height 

 of 3 / 4 — 2 metres. The rod-like erect branches which are often 60 

 centimetres long, and bear at their tops the crowded inflorescences 

 with grey hairs, the small stiff, acicnlate, erect leaves, all these 

 characters indicate a strongly xerophytic nature. 



At the first examination this species seemed to me to constitute 

 a completely new genus. It belongs to the tribe Cinchoneae of the 

 sub-order Cinchonoideae (K. Schumann), and to the sub-tribe Hillieae. 

 On applying the analytical key, prepared by K. Schumann (Natiirl. 

 Pflanz. Fam. IV 4 p. 42) one does not arrive at any genus in parti- 

 cular, but in the immediate neighbourhood either of Cosmibuena 

 Ruiz and Pavon, or of Coptosapi'lta Korth., according as to whether 

 one takes the style to be little or very much longer than the corolla- 

 tube. A closer comparison with the genus Cosmibuena, to which a 

 small number of Central- and South-American, epiphytic shrubs 

 belong, at once, however, reveals considerable differences in the 

 structure of the calyx, stamens, stigma and in the dehiscence of the 

 fruit, so that there can be no question of a union with this genus, 

 although in habit and in the shape of the flowers the agreement is 

 closer than with Coptosapelta. As regards (he latter genus, it is 

 said in the above-mentioned key : "style quadrangular and hairy"^ 

 so that, if one were to adhere strictly to this, one would be forced 

 to set up a new genus for our species, in which the style is cylin- 

 drical and glabrous. On further comparison with the characters given 

 in the generic diagnosis for Coptosapelta, the following differences 

 are also found : C a 1 y x, small, saucer-shaped, five-toothed in Copto- 

 sapelta ; in the new species much longer than the calyx-tube, divided 

 to its base into five lanceolate, pointed, erect divisions. — Corolla- 

 tube very short, as long as or shorter than the lobes of the limb, 

 and hairy at the tube-mouth, in Coptosapelta; in the new species 

 4 — 6 centimetres long, thin and straight, much longer than the lobes 

 of the limb, and glabrous at its mouth. — Anthers almost as
