remarks that this species is perhaps too near M. acanthocarpa. M. Lindheimeri is 

 also too like it. 



161. "M. FLEXUOSA (sp. nov. Ameria Acanthocarpse) : * fruticosa, minute pru- 

 inoso-puberula ; aculeis infrastipularibus geminis conicis rectis ; pinnis 5 - 7-jugis ; 

 foliolis 7 -10-jugis minimis oblongis obtusis crassiusculis puberulis ; capitulis glo- 

 bosis ; legumine lineari rectiusciilo minute cano-puberulo margine tenui aculeato. — 

 Eamuli rigidi, flexuosi, albidi. Aculei caulini csesise, 2 lin. longi ; petiolares minu- 

 tissimi. Stipulse minutse, setacese. Petiolus communis vix semipollicaris. Pinnae 

 confertse, 2-3 lin. longse. Foliola fere imbricata, semilineam longa, rigidula, Isete 

 virentia, utrinque puberula, obtusa, vel rarius mucronulata. Pedunculi fructiferi 

 2-3 lin. longi. Legumen pollice paullo longius, vix 2 lin. latum, rectum vel leviter 

 falcatum, crassiusculum, aculeis marginalibus irregularibus rectis. Aff. M. Lind- 

 heimeri." Benth. in litt. — Mountain valleys beyond the Limpia ; Aug. " A much- 

 branched shrub, 2 or 3 feet high."

163. "M. DYSocARPA (sp. uov. Habbasia) : fruticosa; ramis petiolisque ferru- 

 gineo-villosis ; aculeis sparsis validis subrecurvis; pinnis 6- 10-jugis; foliolis 

 8 _ 10-jugis oblongis acutis sericeo-villosis ; spicis cylindricis; floribus pentameris 

 sericeo-villosis ; calyce corollee dimidium sequante ; legumine lineari-falcato dense 

 tomentoso inermi aut margine aculeis validis sparsis armato. — Aculei ramulorum 

 sEepius solitarii, rarius infrastipulares, petiolorum pauci parvi. Stipulse subulatse, 

 rigidee, villosse, 2-3 lin. longse. Petioli communes sesquipollicares, tomentosi. 

 Foliola conferta, vix 2 lin. longa. Spica densa pollicaris. Calyx fere lineam lon- 

 gus, membranaceus, breviter 5-dentatus. Stamina 10 : filamenta sursum complana- 

 ta. Ovarium villosissimum. Legumen sesqui -bipollicare, 3 lin. latum, apice rigide 

 acuminatum, fere pungens, tomento rufescente dense vestitum, valvulis ab margine 

 crasso in articulos demum secedentibus." Benth. in litt. — Mountain valleys in the 

 Pass of the Limpia and beyond, August ; in fruit. Also in the collection of 1851, 

 in flower. This species seems in some respects to connect the Ameria Acanthocarpce 

 with Habhasia Batocaulon, having the habit and small leaflets of the former ; but 

 the pods, although at first appearing continuous, at length separate into from five 

 to seven articles. 



164. M. MALACOPHTLLA [Gray, PL Lindh. 2. p. 182, adn.): suffrutescens, moUi- 

 ter sericeo-tomentulosa; caulibus procumbentibus angulatis petiolisque copiose 

 aculeatis, aculeis brevibus uncinato-recurvis ; pinnis 4 -7-jugis; foliolis 5-8-jugis 

 ovatis vel ovali-oblongis mucronatis venosis ; panicula racemosa laxa ; fioribus 5- 

 meris 10-andris ; legumine lato-lineari longiuscule stipitato membranaceo glabro 

 nitido inermi 6 - 8-spermo. — On the Rio Grande, in Southern Texas, August, 

 September ; in flower and fruit. Also gathered near Monterey, Northern Mexico, 

 by Dr. Gregg and Dr. Edwards, without fruit; and east of Rinconada by Dr. 

 Gregg in 1848. — Plant with the habit of a Schrankia, canescent with a fine 

 and very soft down ; the partial and general petioles, as well as the stem, beset with
