A species near M. Guianensis. Branches dark, angular, subcompressed, subverrucu- 

 lose, with axils 1-1^ in. apart; leaves suberect, oblong, acutely obtuse at the base, 

 shortly and obtusely acuminate at the apex, fuscous green above, with immersed fine 

 nerves, ferruginously opake below, with dark midrib and prominulent nerves, in the 

 axils of which a porous gland is most frequently seen, 2-3 in. long, f-lj in. broad, 

 on petioles 2-3 lines long ; axillary peduncle bracteolated, 3 lines long ; pedicels 

 slender, 4 lines long ; sepals 1 line long ; tube of corolla cylindrical, contracted in the 

 middle, border hypocrateriform, segments linear oblong, 4 lines long.

A very distinct species. Its erect fuscous branches, dichotomously divided, aresub- 

 fistulose and interruptedly striated ; leaves oblong, acute at the base, obtuse at the apex^ 

 margins subrevolute, rigidly chartaceous, green above, opake, impressed-rugulose, nerves 

 immersed, luridly opake below, somewhat paler, midrib and nerves yellowish and 

 prominulent, with a hollow pilose gland in each axil, 2-2f in. long, |— 1 in. broad, 

 on channelled petioles lJ-2 lines long; inflorescence solitary at each node, or in the 

 dichotomy of the branchlets ; peduncle 2 lines long, bearing 3 flowers, sometimes reduced 

 to 1; pedicels very slender, 12 lines long; sepals obtusely oblong, imbricately erect, 

 carinate, obsoletely puberulous outside, margins membranaceous, f line long, with 

 oblong fl.eshy scales within alternate with them ; tube of corolla 5 lines long, 1 line broad 

 at its base, J line broad at its summit, bearing in its expanding throat 5 obtusely lanceo- 

 late fleshy glands ; segments of border obtuse-oblong, somewhat inequilateral, opposite 

 the glands, glabrous on both sides, rugulous outside at their base, 5 lines long, 2 lines 

 broad; stamens inserted below and alternate with the glands, partly exserted, quite 

 glabrous ; filaments seated on prominent ridges ; disk of 5 erect oval fleshy lobes, shorter 

 than the 2 ovaries, which are pilose on their summits ; style slender below, with an incras- 

 sated clavuncle above ; stigmata 2 short lobes ; follicles terete, black, 4J in. long, 2 lines 

 thick ; seeds very compressed, oblong, smooth, narrower below, peltately affixed to the 

 placenta by a small ovate hilum. 



13. Malouetia Martii, Miill. I. c. p. 94, tab. 29. In Amazonas : v. s. in hb. variis Panure, Rio Uahupes 



(Spruce 2435) . 



A species well distinguished from M. lanceolata by its much smaller, very dusky 

 leaves, sharply acuminate, luridly ferruginous beneath, without the usual porous 

 glands, in its darker corolla furfuraceous (not pubescent) within. It bears much the 

 aspect of M. virescem. Spruce's plant agrees with Miiller's diagnosis ; but it is wrongly 

 quoted as from the province of S. Paulo. Its leaves are 2-2f in. long, | in. broad, on a 

 petiole 2f-3 lines long; the peduncle is 1 line long, the pedicels 6 lines long; the 

 sepals 1 line long ; the tube of the corolla 6 lines long ; its segments furfuraceous, 4 lines 

 long, with dextrorse convolution; anthers exserted, furfuraceous.
