hairs upon raised tubercles; tube of corolla 1 line long, with 
segments of equal length; anthers cohering in the mouth by 
their acuminated papillose summits; style glabrous, with a 
turbinated fringed summit, crowned by a short, oblong, pilose 
stigma.

DC. Prodr, 1x. 526; Fresen. in Mart. Fl. Bras. xix. 55 3;— 
scandens ?, glaberrima, ramis angulato-sulcatis ; foliis ellip- 
ticis, acuminatis, imo obtusis, petiolatis: paniculis axillari- 
bus, ferrugineo-subvelutinis, folio dimidio brevioribus ; se- 
palis corolleeque lobis subulatis, tubo subvelutino dimidio 
brevioribus.—In Brasilia, in montibus Organensibus (non 
vidi). 
From the above brief character, this species differs from 
M. Organensis in its always axillary panicles, of only half 
their length, and which are ferruginously velutinous ; its 
leaves, somewhat smaller, have a comparatively longer petiole; 
and the flowers are pubescent. It is said to be near M/. macro- 
loba, but I have seen neither of them. Its leaves are stated to 
be 24 inches long, 8-12 lines broad, on a petiole 3-5 lines long ; 
the corolla is 2 lmes long.

longis aut ovato-oblongis, acuminatis, imo rotundatis, supra 
tenuissime pubescentibus, subtus cano-tomentosis; petiolo 
teretiusculo, cano-tomentoso: paniculis axillaribus, dicho- 
tome multifidis, cano-tomentosis ; spicis 20-24, filiformibus, 
diffusis ; floribus unilateralibus, distantibus ; sepalis corolle- 
que lobis acuminato-subulatis; drupis glabris, 4-gastris.— 
In Cumana (non vid?), 
Kunth does not state the length of the inflorescence or the 
size of the leaves ; but their petioles are said to be 3 or 4 lines 
long. Fresenius has confounded with this species the MZ. mem- 
branacea, Gardn., which is a very different plant.
