Flores hermaphroditi. Calyx ample tubuloso-eampanu- 

 latus, subinflatus, 5-8-dentatus. Corolla tubulosa. Sta- 

 mina numerosissima, monadelpha, tubo basi corollae adnato, 

 filamentis superne liberis longe exsertis. Ovaria plura, ses- 

 silia. Styli elongati exserti. Legumen crassum rectum. Semina 

 funiculo longo appensa. — Frutices v. arbores, Brasilienses, 

 habitu Ingge, inermes. Folia simpliciter abrupte pinnata. 

 Petiolus inter jug a foliolorwn alatus v. nudus. Glandules 

 inter omnia paria scutellatts v. stipitata. Foliola opposita, 

 paucijuga, majuscula. Flores inter Mimoseis magni, nunc 

 sessiles dense spicati, nunc breviter pedicellati,racemosi. Bracteae 

 vel breves laocce vel dense imbricates. Calyx et corolla villosa. 

 Stamina et styli glabra. Ovaria brevia villosissima. 



This genus was established many years since by Auguste 

 de St. Hilaire, and often adverted to upon his authority, but 

 does not appear to have been since examined, although more 

 than one species have been gathered in the vicinity of Rio 

 Janeiro, or Bahia. This circumstance is probably owing to 

 their having been taken for species of Inga, which they 

 resemble most closely in every thing but the number of 

 ovaria, and some slight difference in the calyx and corolla. 



The number of ovaries is usually three, of which one 

 appears to be the front one and two lateral ones, the seminal 

 suture being always, as might be expected, turned towards 

 the central axis of the flower. I only twice found five, 

 regularly placed round the central axis, and once I met with 

 six, the additional one being in the centre of the five others.
