Dalea thyrsijlora (sp. nov.) : fruticosa, cinereo-pubescens ; cauHbus 

 erectis paniculato-ramosis ; foliolis 3 - 5-jugis (seu fol. supr. 1 - 2-jugis) 

 ovalibus membranaceis subtus ramulisque grosse nigricanti-glandulosis ; 

 spicis axillaribus et terminalibus breviter pedunculatis thyrsoideo-pani- 

 culatis confertis brevibus (nunc inferne sublaxifloris) ; calyce cum brac- 

 tea oblongo-ovata acuminata tubo sequilonga grosse glanduloso, dentibus 

 subulato-setaceis villosis demum patentissimis apice uncatis tubo sub- 

 longioribus. — Monterey and San Fernando in the northern part of 

 Mexico, and farther south from Victoria to Tula, coll. Berlandier, no. 

 763, 846, 1386, 2183, 2266. — Shrub 10 feet high, according to Er- 

 vendberg ; the branches herbaceous. Leaves pale and dull. Leaflets 

 3 to 6 lines long, obtuse at both ends, copiously dotted underneath with 

 dark glands. Spikes very numerous, on short and slender, often 

 branching peduncles, forming a leafy crowded panicle, the flowers often 

 scattered on the lower part of the rhachis, or a few glomerate in the 

 axils of the uppermost and reduced leaves. Flower about 3 lines 

 long ; corolla apparently flesh-color or ochroleucous, scai'cely exceeding 

 the lower tooth of the calyx. Legume villous.* 



Also Tephrosia cinerea, Pers. (19) and 2\ Schiedeana, Schlecht. 

 (307), but with axillary racemes and more acute calyx-teeth. 



Diphysa Carthaginensis, Jacq. ? (23) : the pedicels are long, and 

 the leaflets are emarginate, as in Seemann's specimens from Panama ; 



* The other Daleas of Berlandier's collection are : — 



Dalea fmtescem, Gr&y {\mi) ; D. tuberculata, 'Lag. (783, 1238, 2203), agreeing 

 with Lagasca's character " foliis canescentibus " better than with De Candolle's ; 

 D.pulchella, Moric. (782, 1337,2202) ; D. leucostoma, Schlecht. ■? but more pubescent, 

 and with fuscous spikes, perhaps Lagasca's D. virgata, which is imperfectly charac- 

 terized (837, 2257 and 761, 2181) ; D. triphylla, Pav. (1214) ; D. hxiflora, Pursh, 

 which is mainly Moricand'sZ).joe?ii«7toa (1747) ; D. pogonathera, Gray (613, 2023) ; 

 D. lasiathera, Gray (1014, 2444); D. nana, Torr. (2053); D. aurea, Nutt. (953, 

 2383, and a very silky variety, 1016, 2446); and the following, which I am unwill- 

 ingly obliged to describe as new : — 



Dalea Berlandieri (sp. nov.) : fruticosa, erecta, glaberrima, ramosissima; ramulis 

 gi'acilibus vix glandulosis; foliolis 2-3-jugis parvis obovato-oblongis cuneatisve 

 retusis subcrassis glaucescentibus subtus rhachique grosse glandulosis ; spicis villo- 

 sis laxifloris ; bracteis carnosulis ovato-lanceolatis sensim acuminatis carinatis cilia- 

 tis calyce brevioribus deciduis ; dentibus calycis e basi lata aristatis villosissimis 

 infra medium denticulis 2 setaceis plerumque instructis tubo campanulato pubes- 

 cente grosse glanduloso subduplo longioribus ; petalis rubescentibus. — In the 

 mountains near San Carlos, Tamaulipas, Berlandier coll. 942, 2372. — Petiole and 

 rhachi.'i 2-5, leaflets 1-3, lines long. Calyx teeth in fruit 3 lines long.
