NOTES ON MIMOSEÆ. 595 
51. I. Pavoniana, ramulis novellis ferrugineo-puberulis 
demum foliisque glabris, stipulis ovato-lanceolatis striatis, 
foliolis 3-4-jugis ovali-v. elliptico-oblongis breviter acuminatis 
basi inaequaliter cuneatis supra nitidulis subcoriaceis, pedun- 
culis longiusculis fasciculato-paniculatis, spicis breviter ovatis, 
floribus breviter pedicellatis, calyce tubuloso puberulo quam 
corolla sericea duplo breviore, legumine plano glabro v. vix 
minute puberulo.—I. Riedeliane similis, sed distincta videtur. 
Foliola minora. Inflorescentia et presertim flores minus 
villosa.  Stipule superiores, imprimis foliorum floralium 
abortientium, rigidæ, 3-4 lin. longæ, diu persistentes. Flores 
tenuiores, corollæ ratione calycis paullo longiores. Legumen 
3-poll. longum, 9 lin. latum.—Sent by Mathews from Pavon's 
herbarium at Lima. 
52. I. Riedeliana, ramulis novellis ferrugineo-puberulis 
demum foliisque glabris, stipulis parvis deciduis, foliolis 
3-jugis ovali- v. elliptico-oblongis breviter acuminatis basi 
inæqualiter cuneatis supra nitidulis, spicis fasciculato-pani- 
culatis ovatis, floribus breviter pedicellatis, calyce tubuloso- 
pubescente corolle sericeo-villose dimidium superante, 
legumine plano puberulo.—Foliola fere I. corymbifere sed 
rigidiora et semper trijuga videntur, ultima vix 5-pollicaria; 
vene subtus interdum leviter tomentelle. Flores I. corym- 
bifere, sed stipatæ pedicello 4-1 lin. longo bracteas eequante. 
—Woods on the Amazon river, Riedel. 
B? Surinamensis, floribus brevius pedicellatis.—Surinam, 
Hostmann, n. 830, 971, and in some collections n. 174.— - 
This variety is in some measure intermediate between 
I. Riedeliana and Y. corymbifera, and may possibly be a 
distinet species, unless further observation may show both 
I. Pavoniana and I. Riedeliana to be mere forms of I. corym- 
bifera.
