In Amazonas: v. s. in herb. variis Panuré, 
Rio Uahupes (Spruce 2472). 
A species near M. Guianensis. Branches dark, angular, subcompressed, subverrucu- 
lose, with axils 1-14 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, 24-14 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.

Bras. xxvi. p. 92. In Venezuele confinibus: v. s. in herb. variis Rio Casiquiare (Spruce 3305). 
A very distinct species. Its erect fuseous branches, dichotomously divided, are sub- 
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, 2-22 in. long, $—1 in. broad, 
on channelled petioles 11-2 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, } line long, with 
oblong fleshy scales within alternate with them; tube of corolla 5 lines long, 1 line broad 
at its base, 4 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, 4) in. long, 2 lines 
thick; seeds very compressed, oblong, smooth, narrower below, peltately affixed to the 
placenta by a small ovate hilum.,

(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. virescens, Spruce’s plant agrees with Müller's diagnosis; but it is wrongly 
quoted as from the province of S. Paulo. Its leaves are 2-2% in. long, $ in. broad, on a 
petiole 23-3 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 lone; 
g; its segments furfuraceous, 4 lines 
long, with dextrorse convolution; anthers exserted, furfuraceous.
