§ 5. PENNINERVIA. 
49. M. LANATUM (Tul. in Arch. Mus. Par. iv. p. 96), inerme, foliolis 
11-21 oblongis v. ovali-oblongis obtusis utrinque molliter tomentoso- 
villosis penniveniis, paniculis oblongis floribundis folio brevioribus, 
floribus sessilibus, vexillo sericeo, staminibus monadelphis.—Foliola 
2~2-pollicaria. Flores circa 4 lin. longi. Legumen non visum. 
Hab. Brazil, prov. Minas Geraes. 
At first sight very near the M. villosum ; but the leaflets are downy 
above as well as below, and the venation is rather that of the Penninervia. 
50. M. nigrum (Vog. Linnea, xi. p. 188), inerme, foliolis 11-15 ovali- 
oblongis obtusis v. rarius acutiusculis supra demum glabratis subtus 
dense subsericeo-pubescentibus elevato-penniveniis, panieulis laxis 
dense tomentosis, floribus sessilibus, vexillo sericeo, staminibus mona- 
delphis, legumine tomentoso.—M. velutinum, Benth. in Ann. Mus. Vind. 
ii. p. 100; Nissolia fruticosa, Vell. Fl. Flum. vii. t. 86 ?—Foliola 2-3- 
pollicaria, venis primariis supra impressis subtus prominentibus. 
Flores 5 lin. longi. Legumen 2-pollicare, ad semen 4 lin. latum. 
Hab. Brazil, near Rio Janeiro. 
51. M. LINDENIANUM, sp. n., inerme, foliolis 5-9 ovalibus obtusissimis 
retusisve supra glabris levibus, subtus elevato-penniveniis ferrugineo- 
tomentellis, panicula terminali floribusque ferrugineo-tomentosis, flo- 
ribus sessilibus, staminibus monadelphis.—M. ferrugineo valde affine 
et forte varietas, differt floribus multo minoribus (vix 4 lin.) subsessili- 
busque et foliolis obtusioribus. 
Hab. Caraccas, Linden, n. 1647. 
52. M. FERRUGINEUM (Pers. Syn. ii. p. 276), inerme, foliolis 5-11 ova- 
libus oblongisve mucronato-acuminatis rarius obtusatis supra glabris 
levibus subtus elevato-penniveniis ferrugineo-tomentosis puberulisve, 
panicula terminali ferrugineo-tomentosa, floribus pedicellatis rufo- 
tomentosis, staminibus monadelphis, legumine tomentoso.— Nissolia 
quinata, Aubl. Pl. Gui. ii. t. 297 ; Nissolia ferruginea et N. diadelpha, 
DC. Prod. ii. p. 258; Macherium diadelphum, Уор. Linnea, xi. 
p. 182; M. nervosum, Vog. 1. с. p. 186.—Foliola sepe opposita, 3-5- 
pollicaria, margine sepius recurva, Panicula pyramidata, floribunda. 
Flores subsemipollicares, vexillo rufo-tomentoso. Legumen 3-polli- 
care, ad semen 6 lin. latum.

53. M. MacRopHYLLUM (Mart., Benth. in Ann. Mus. Vind. ii. p. 99, 
et in Mart. Fl. Bras. Leg. ined.), inerme v. stipulis breviter indu- 
rato-spinescentibus, foliolis 5-7 amplis ovalibus obtusis coriaceis gla- 
bris v. subtus tenuissime ferrugineo-pubescentibus crebre penniveniis,
