NOTES ON MIMOSE^E. 93 



calyce minuto, corolla ten ui fere 1| lin. longa. — Zimapan in 

 Mexico, Coulter. 



M. depauperata, p. 410. — Acacia canescens, Mart. Gal. in 

 Bull. Acad. Bruss. 10, pars 2, p. 314. — Mexico, Galeotti, 

 n. 3214. 



M. polyantha, p. 410. — Either the same species or one 

 closely allied to, it was gathered by Coulter with the Prosopis 

 pubescens between San Miguel and Monterey in California. 

 After this add : 



M. laxiflora, sp. n.; glabra, pallescens, aculeis sparsis 

 recurvis raris, stipulis minutis setaceis, pinnis remotis 2-3- 

 jugis, foliolis remotis 3-6-jugis oblique oblongis, spicis laxis 

 cylindricis, floribus breviter pedicellatis glabris 4-meris, calyce 

 corolla tri-quadruplo breviore. — Affinis videtur hinc M. re- 

 motes inter Rubicaulibus, hinc M. polyantha inter Acantho- 

 carpis, et fructu ignoto locus incertus. Ramuli graciles. 

 Petioli communes tenues, 5-3-pollicares, Foliola parva, 

 pauca. Spicee brevissime pedunculatse, poilicares v. paullo 

 longiores. — Sonora alta, Mexico, Coulter. 



To the Mimosa unknown to me, must be added M. ar- 

 cuata, Mart, et Gal. from Mexico j M. dominiciana, Desv. 

 from Dominica. 



Of the Species dubia addenda of Walpers, Repert 1, p. 882. 

 M. glaberrima is my Albizzia glaberrima ; M. adianthifolia y 

 Schum, must be a Zygia and M. guinensis an Albizzia; 

 M. pentagona is scarcely sufficiently known to determine the 

 genus ; M. procumbens, Schum. has been referred in a former 

 part of this paper to M. asperata, M. bicolor, Schum. to 

 Dichrostachys nutans and M. adstringens, Schum. to Acacia 

 Adansoni; M.pumila, Schlecht. is, as above suggested, pro- 

 bably a Desmanthus; M. Kermesina is my M. lucidula; 

 M. meticulosa, Mart, is included among the true Mimosa; 

 M. adharens referred to Acacia adharens and M. acacioides 

 Benth. to Piptadenia peregrina, so that a very little attention 

 on the part of the compiler might have reduced considerably 

 these "Species dubia;." Lastly M. moniliferu, Bcrtol. is 

 probably M. floribunda.
