A TRIBE OF LEGUMINOSX. 59 
tello ad semen valde intruso, dorso valde arcuato.—Stipulas delapsas 
non vidi. Foliola, in specimine fructifero, fere M. ampli, ultra pollicem 
longa, 4 lin. lata, in florifero 8-10 lin. longa, venis tamen quam in 
Lineatis minus conspicuis et evidentius anastomosantibus. Panicula 
multiflora, basi foliata. Calyx tomentosus, fere sessilis, linea paullo 
longior. Flos totus vix 3 lineas superans. Ovarium uti carina valde 
arcuatum. Legumen bipollicare v. paullo longius, crassiusculum, 
basi fere ut in Drepanocarpo curvatum, ad semen 5-6 lin. latum, ala 
gladiata medio 8 lin. lata. 
Hab. Venezuela, Moritzi, n. 883 (in fruit); Fendler coll. 1. n. 1750 (in 
flower), and coll. 2. n. 1866 (in fruit). 
I am not quite certain of having correctly matched the flowering and 
fruiting specimens, and I have also doubts whether the species would 
not be better placed near the M. angustifolium. It is, however, quite 
distinct from that species, especially in the pod, which at the base is like 
that of a Drepanocarpus ou a small scale, with the long wing of Mache- 
rium at the end. 
18. M. MYRIANTHUM (Spruce ; Benth. in Mart. Fl. Bras. Leg. ined.), 
inerme, foliolis 35-51 lineari-oblongis obtusis coriaceis tenuissime re- 
ticulato-venulosis subtus paniculisque fusco-pubescentibus, panicula 
ampla, floribus parvis confertis, vexillo glabro, staminibus monadelphis. 
Foliola 8-12 lin. longa, circa 3 lin. lata. Flores vix 3 lin. longi, sessiles. 
Petala carinalia angusta, parum arcuata, vix connata. Legumen 
pubescens, basi leviter curvatum. 
Hab. North Brazil? and Venezuela, near Panuré, on the Rio Uaupés, 
Spruce, n. 2758. 
19. M. борроті, зр. n., inerme, stipulis linearibus deciduis, foliolis 
21-35 lineari-oblongis obtusis retusisve glabris puberulisve reticulato- 
venulosis, racemis tomentellis, stamine vexillari subsoluto, ovario bre- 
vissime stipitato rectiusculo villosissimo, legumine pubescente.— Foliola 
6-9 lin. longa, 2-3 lin. lata, primo intuitu iis M. angustifolii simil- 
lima ; sed venatio longe diversa ; venulz enim irregulariter reticulate, 
nec parallele. Racemi in specimine simplices, 1-1i-pollicares. Pe- 
dicelli brevissimi. Bracteolæ } lin. longze, calyci non appressz. Calyx 
1} lin. longus, pubescens, dentibus fere ad tertiam partem attingentibus. 
Petala superiora, jam delapsa, non vidi. Carina calyce vix duplo longior, 
latiuscule falcata, petalis longe unguiculatis dorso connatis. Staminum 
vagina postice integra, filamento vexillari (anthesi peracta) fere a basi 
soluto. Ovarium fere sessile, uniovulatum, stylo inflexo glabro. Legu- 
men 2-2} poll. longum, basi 4 lin. latum, tomento rufo pubescens, ad 
semen intrusum, ala supra medium fere 9 lin. lata. 
Hab. New Granada, at Ratata or Oratata (the name not very legible), 
Goudot. | 
The two specimens I have seen in DeCandolle's Herbarium are not 
good; but the species is evidently distinct from all others, especially in 
the ovary. ,
