COLLECTED BY MR. SPRUCE AT PARA. 239 
I have some doubts whether both 7. staminea, DC., and V. phacelo- 
carpa, may not be mere varieties of V. bifolia. The following, how- 
ever, which was generally distributed, is a perfectly distinct species 
from any of the five previously published. 
Vouapa angustifolia, sp. n., foliolis sessilibus oblique lanceolato-oblongis, 
racemis folio brevioribus, bracteis ovatis acuminatis alabastrum 
acuminatum equantibus, ovario glabro v. ciliato.—Ramuli ramosis- 
simi, tenues, teretes, glabri. Stipule minute, ovate, caduce. 
Petiolus communis 3-5 lin. longus, seta nulla. Foliola 2—5 poll. 
longa, 3-1 poll. lata, basi oblique acuta, glaberrima, coriacea, 
uninervia, crebre et tenuiter transversim parallele venosa, et inter 
venas reticulata. Racemi 2-3-pollicares, pube aurea v. canescenti 
tomentosi. Bracteze 3-4 lin. longe, concave, extus tomentose, 
intus glabre, per anthesin decidue. Bracteole ovate, acuminate, 
concava, extus tomentose. Calycis lacini: glabrz, ovate, acumi- 
natz, bracteolis paulo breviores. Ovarium versus margines pilis 
nonnullis ciliatum nec tomentosum.—On the banks of an igarapé 
of the Rio Para, near Caripi, Spruce ;. on the Amazon, Riedel. 
Among sixteen Mimosee, there are several interesting species, and 
one new Inga, which I have great pleasure in naming after its discoverer. 
Inga (Burgonia) Spruceana, sp. n., glabra v. vix puberula, foliolis 
4—5-jugis ovatis oblongisve obtuse acuminatis basi inzqualiter 
angustatis submembranaceis, petiolo vix sub jugis dilatato, glandulis 
elevato-scutellatis, spicis aggregatis breviter pedunculatis breviter- 
que oblongo-cylindraceis, calyce ovoideo corolla triplo breviore, 
tubo stamineo longe exserto.—Arbor ramulis tenuibus.  Petioli 
4-7-pollicares, tenues, glabri v. vix puberuli. Glandule inter 
omnia paria, haud magna.  Foliola breviter petiolulata, 3 v. rarius 
4 poll. longa, 1-2 poll. lata, consistentia quam in affinibus multo 
tenuiore. Spice in ramulos breves e nodis vetustis ortos v. ad 
axillas foliorum fasciculate, cum pedunculo pubescente 3—5-lineari 
vix pollicem excedunt. Bracteze minute, acute. Calyx semilineam 
longus, puberulus, breviter dentatüs. Corolla infundibuliformis, 
fere glabra; tubus fere lineam longus; limbus latus, profunde 
5-fidus, 3 lin. longus, laciniis acutis. Staminum tubus corolla duplo 
longior.—A tree of fifty feet, with whitish flowers; found on the 
Unah road, near Parà.
