 segments 2^ Hnes long, densely pubescent within at their base; stamens inserted near

 This species is very distinct from T. muricata, R. & Sch., differing in its much smaller 

 leaves, which are elliptic, canaliculately recurved at both ends, acute at the base, with a 

 long narrow acumen at the apex, margins revolute, pale green above, opake, with nume- 

 rous obsolete parallel corrugated lines, nerves immersed, opake and yellow below, with 

 prominulent midrib and nerves, without the slightest indication of the peculiar dots, 

 elevated above, impressed below, which characterize the species described by E-omer 

 and Schulz. In the present instance the leaves are only ^^A in. long, IJ-l^ in. broad, 

 on petioles 3-4 lines long (in T. muricata they are above 7 in. long, on very short petioles) ; 

 corymb terminal and many-flowered, half or a third the length of the leaf ; peduncle 

 very short, primary and secondary branches elongated; pedicels twice as long as the 

 calyx, with a small basal bracteole ; calyx barely 1 line long ; the very slender tube of the 

 corolla is 1 in. long, a little swollen at the base, segments oblong, curving, 5 lines long, 

 sinistrorsely convoluted in aestivation ; stamens inserted a little above the base of the 

 tube ; disk none ; 2 free ovaries, with a very short style incrassated at its summit by a 

 long 5-angular clavuncle and 2 small terminal stigmata.

This plant accords with Kunth's description. Its dichotomous, pallid, stout branchlets 

 are rugously striated, marked by annular rings 4-6 lines apart where the leaves have 

 fallen off; in the upper part they are sub-4-angular ; the leaves, rarely quite equal in 

 each node, are oblong, or subovate, subacute and insequilateral at the base, rather 

 obtusely acute, and mucronated at the apex, margins subrevolute, submembranaceous, 

 pale green above, yellowish opake below, nerves rather patent and prominulent on both 

 sides, 4-5j in. long, 2-2J in. broad, on channelled petioles 3-5 lines long, conjoined 

 across the node by an arched ridge ; some of the upper leaves often smaller ; axillary 

 opposite corymbs 2 in. long and broad, very dichotomously branched, many-flowered, on 

 bracteolated pedicels 2 lines long ; sepals acute, reflected at the apex, 1 line long ; tube 

 of corolla cylindrical, broader at the base, 5 lines long, segments 4 lines long, 2 lines 

 broad, sinistrorsely convoluted, very pubescent within at the base ; stamens 2J lines long, 

 seated near the base of the tube ; 2 ovaries oblong, free, without any disk ; clavuncle, 

 style, and stigmata as usual.
