slender, 3 lines long; sepals acutely ovate, imbricated, with membranaceous margins, 
1 line long, each with an internal 4—5-laciniated scale; tube of corolla narrowed above 
the middle, swelling to the base, pubescent above within, 44 lines long, with dolabriform 
segments 21 lines long, densely pubescent within at their base; stamens inserted near 
the base of the tube; disk none; 2 pointed oblong free ovaries; style, clavuncle, and

This species is very distinct from 7. 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 Rómer 
and Schulz. In the present instance the leaves are only 31—4 in. long, 12-14 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, eurving, 5 lines long, 
sinistrorsely convoluted in «estivation; 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, 4-5} in. long, 2-2) 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, sinistrórsely convoluted, very pubescent within at the base; stamens 24 lines long, 
seated near the base of the tube; 2 ovaries oblong, free, without any disk; clavuncle, 
style, and stigmata as usual.
