*^* Garce Posteriores, 1868. 

 PARRYELLA, Tori\ & Gray, Nov. Gen. Leguminosearum. 



Caiyx obconicus, 5-dentatus, dentibus brevibus sequalibus. Petala 

 nulla. Stamina 10 : filamenta ima basi calycis inserta, libera : antherae 

 uniformes. Ovarium biovulatum ; stylus crassiusculus e calyce leviter 

 exsertus, apice uncinatus ; stigma glandula^forme laterale EysenhardticB. 

 Legumen indehiscens, oblique obovatum, grosse glandulosum, basi at- 

 tenuata calyce persistente stipatum, semine solitario ovali repletum. 

 Cotyledones oblongce, foliaceaj ; radicula inflexa. — Frutex Novo-Mex- 

 icanus, parvus, ramosissimus, fere glaber; ramis tenuibus scopariis foliis- 

 que parce glanduloso-punctatis ; foliolis plurijugis cum imparl filifor- 

 mibus canaliculatis petiolulatis ; stipulis stipellisque nullis vel ad 

 glandulas parvas reductis ; floribus pusillis in spicis terminalibus. 



Paryella filifolia. — New Mexico, along the Rio Grande be- 

 low Albuquerque, Dr. C. C. Parry. Flowers barely a line and a half 

 in length ; the turgid Psoralea-VikQ legume 3 or 4 lines long, not wrin- 

 kled, smooth, but beset with large yellowish glands in the manner of 

 Dalea^ its base only covered with the turbinate persistent calyx. Fila- 

 ments and pubescent style barely exserted. Although the stamens are 

 distinct to the bjtse, yet this is evidently a true Psoraleaceous plant, and 

 closely related to Eysenhardtia ; but not to be confounded either with 

 that genus or Amorpha. The preoccupation of the name Parrya in 

 behalf of the arctic navigator need not frustrate the natural desire that 

 our Dr. Parry's name should be commemorated in a generic type 

 of his own discovery, inhabiting some of the wide western regions 

 which he has so faithfully explored during the past twenty years. 



Dalea Parryi, Torr. & Gray : suffruticosa, tenuiter puberula ; 

 ramis gracilibus difFusis mox glabris ; foliolis 7-11-jugis obcordatis 

 vel obovatis emarginatis (1J--2 lin. longis) parce grossius glanduloso- 

 punctatis ; spicis longe pedunculatis elongatis multifloris demum laxis ; 

 calyce sericeo-canescente ad medium usque 5-fido, lobis 4 oblongis 

 obtusis, infirao lanceolato acuto pauUo longiore ; corolla saturate vio- 

 laceo ; leguraine glabello. D. divaricata var. cinerea, supra, p. 335. 

 — Gravelly hills near Fort Mohave, Dr. J. G. Cooper, and lower 

 down on the Colorado, near the mouth of Williams River, Dr. C. C. 

 Parry. The specimens of the latter are smoother as to the foliage, and 

 therefore agreeing in this respect with Bentham's D. divaricata of 

 Lower California ; but the silky-canescent calyx (fully a line and a
