82 NOTES ON MIMOSE^E. 



epicarp, a sweet fleshy continuous sarcocarp, and a mem- 

 branous crustaceous or bony endocarp either continuous or 

 separated into distinct articulations, thus differing from 

 Piptadenia and Mimosa, in both of which there are species 

 with and without transverse articulations, by the presence 

 of the sarcocarp.

P.? heterophylla, sp. n. ; glabra, petiolis longissimis com- 

 planatis, pinnis 1-2-jugis v. abortivis, foliolis 12-15-jugis 

 oblique oblongis parvis, spicis subsessilibus folio brevioribus, 

 legumine piano marginibus incrassatis. — Sonora alta in 

 Mexico, Coulter. Although I have not seen the flower of 

 this plant, and the pod is thinner than usual (about 4^ inch 

 long and 5 lines broad) the general habit of the plant is 

 much more that of a Prosopis than of any other genus. It 

 is most remarkable by the almost phyllodineous vertical 

 expansion of the common petiole, which is from 3 to 7 inches 

 long, and about a line or a little more or less broad. I have 

 seen but a single specimen in the herbarium of Trinity Col- 

 lege, Dublin. 



To the doubtful species (probably of the section Alga- 

 robia) must be added P. fceculifera, Desv. Ann. Sc. Nat. 

 Par. Ser. 1, v. 9, p. 426, or Inga faculifera, Desv. in Ham. 

 Prod. Ind. occid. p. 61. 



After P. strombulifera, p. 352, add : 



P. j>ubescens, sp. n.; stipulis spinescentibus subulato-conicis 

 foliorum pinnis plerisque unijugis, foliolis 5-8-jugis oblongis 

 obovatisve obtusis puberulis, spicis elongatis pubescentibus 

 subinterruptis, corolla calyce duplo longiore, staminibus 

 exsertis, antheris glanduliferis, legumine dense spiraliter 

 contorto. — Frutex, habitu ad P. strombuliferam accedens, 

 inflorescentia distinctissimus. Foliorum petiolus communis 

 2-4 lin. longus, pinnae pollicares, foliola 3-4 lin. longa v.
