B. Hyptianthera rhamnoides, Zoll. efc Mor. in Zoll. Syst. Verzeichn. 60. 

 Dondisia horrida, Korth. in Ned. Kruidk. Arch. II, 236. 

 In all the provinces : not uncommon. 



We have liere reduced Blume's species G. horridum to tho older one of 

 Roxburgh ; for we can find no character to separate the two, the form of the spines 

 the size of the fruit, and the amount of pubescence hitherto relied upon being as 

 a matter of fact inconstant. 



3. Canthium molle, King & Gamble, n. sp. A straggling spiny shrub 

 ( ? scandent) ; all parts more or less densely pale rusty-pubescent ; the 

 young branches thinner than a goose-quill, dark-brown, more or less 

 4-angled ; spines stout, supra-axillary, much curved downwards, '2 to 

 •6 in. long. Leaves thickly membranous, ovate to ovate-lanceolate, 

 shortly acuminate, the base cuneate or rounded ; main-nerves about 5 

 pairs, spreading, slightly prominent on the lower surface when dry, 

 obsolete on the upper; length 2 to 3 in.; breadth '75 to 1*5 in.; petioles 

 •15 to '2 in.; stipules broadly triangular, apiculate, very short. Flowers 

 •2 in. long, on pedicels nearly as long, in small axillary cymes or on 

 short, minutely bracteolate, sometimes leaf-bearing, axillary branches. 

 Calyx small, cupular, with 5 small acute teeth. Corolla with a wide 

 tube glabrous outside, but inside with a ring from the throat of long 

 deflexed white stout hairs : the lobes of the limb about as long as the 

 tube, narrowly oblong, glabrous, deflexed. Anthers sessile, shortly 

 oblong, exserted. Style exserted ; stigma large, ovoid-globose, ridged. 

 Fruit unknown.

4. Canthium conpertum, Korth. in Ned. Kruidk. Arch. II, 235. 

 A shrub? everywhere glabrous ; young branches rather thicker than a 

 crow-quill, pale brown and striate when dry. Leaves coriaceous, oliva- 

 ceous when dry, elliptic or elliptic-lanceolate, shortly and bluntly acu- 

 minate, the base narrowing into the petiole ; both surfaces dull, the 

 reticulations obsolete ; main-nerves 3 (rarely 4) pairs, oblique, ascend- 

 ing, scrobiculate at the axils, rather faint on both surfaces; length 2*5 

 to 4 in.; breadth 1'25 to I '75 in.; petioles about 3 in., winged in the upper 

 half; stipules triangular, acuminate, much shorter than the petioles. 

 Cymes sessile, shorter than the petioles, the very short axis bearing a 

 few minute bracts and 6 or 8 flowers on pedicels *1 in. long. Flowers 

 •25 in. long. Calyx very short and cupular, with 5 often minute teeth. 

 Corolla coriaceous, rotate, the tube very short : the 5 lobes broadly tri- 

 angular with thickened edges, reflexed, villous inside and bearing be- 

 tween the lobes 5 ovate exserted anthers on short filaments. Style 1 in. 

 long, bearing a large capitate-peltate corrugated stigma. Bisk large, 

 thick, cushion-like. Fruit solitary, on a thin peduncle '15 in. long, 

 compressed, obovate, smooth, cushion-like, glabrous. Hook. fil. Fl. Br.
