590 NOTES ON MIMOSEÆ. 
densis, floribus minute pilosiusculis, calyce campanulato 
corolla 4-plo breviore, tubo stamineo vix exserto.—Arbor 
habitu et inflorescentia I. excelse et I. puberule similis sed 
flores confertiores et ala petioli ad foliola inferiora attingit et 
superne utrinque 1-2 lin. lata est. Corolla 2 lin. longa. Legu- 
men ignotum.— Province of Mozobamba, Peru, Mathews. 
The I. martinicensis, Presl. inserted below n. 47 may pos- 
sibly belong to the section Boargonia. 
Sect. IV. Pseunixca. Spice ovate dense v. longiores 
basi laxæ v. interrupta. Flores sessiles v. rarius brevissime 
pedicellati. Calyx tubulosus v. anguste tubuloso-campanu- 
latus. Corolla speciebus paucis exceptis, villosa. Legumen 
planum, marginibus elevatis latitudine leguminis multo 
angustioribus.—This section is readily distinguished from 
the preceding ones by the inflorescence, from Euinga it is 
scarcely known but by the pod. The flowers are usually 
more slender, the calyx smooth or clothed with appressed 
hairs, the corolla generally very hairy, but in the Glabriflore 
quite smooth, sometimes as small as in the preceding 
sections, sometimes two or three times as long, the petiole 
often without wings, but sometimes as broadly winged as in 
Euinga. As there are so many species of which the pod is 
unknown, the limits between this section and Euinga cannot 
be as yet very precisely defined, and itis very likely that 
some species may here be impropeily referred to the one or 
to the other, 
§ 1. Glabriflore. — Calyx glaber v. tenuiter pubescens. 
Corolla glabra. Series a Bourgoniis inflorescentia et calyce 
longiore differt. 
* Petiolo alato. 
37. L. sapida (Humb. et Kunth, Nov. Gen. et Sp. 6 
p. 286), glaberrima, petiolo anguste alato, foliolis bijugis 
elliptico-oblongis acuminatis basi membranaceis, glandulis 
siepe obscuris, pedunculis brevissimis, spicis ovato-oblongis, 
floribus parvis, corolla calyce subtriplo longiore, tubo sta- - 
mineo longe exserto.—Foliola ultima 5 poll longa, 2 poll.
