7180. CaLtianpra? HERBACEA (Engelm. Mss.): ‘caule humili erecto flexuoso ad- 
presse piloso; stipulis lanceolatis nervosis; foliis longe petiolatis ; pinnis 3 —4-jugis ; 
foliolis 20-30 obliquis oblongis obtusiusculis ciliatis supra glabris subtus laxe reticulatis 
adpresse pilosis ; capitulis florum binis folio brevioribus, pauci- (8-10-) floris ; calycibus 
tubulosis 4—5-dentatis, dentibus tubo subbrevioribus ciliatis; tubo corolle calyce triplo 
longiore dentibus obtusiusculis apice parce pilosis; staminibus 25-30 corollam longe 
superantibus. — Between San Miguel and Las Vegas; flowering in August. — Plant 
apparently perennial, 6 inches high: leaves with petioles 3 inches long: leaflets 3 lines 
long: heads about one inch in diameter, on peduncles of one inch in length. Flowers 
polygamous: a fertile flower which I examined had four calyx and four corolla teeth, a 
sterile one, five teeth: stamens united at the base, more so in the fertile flower. Ovary 
elongated, with many ovula and the tumid sutures glabrous.” Engelm. — There is 
another apparently new species in the collections of Wislizenus and Gregg.* 
181. Mimosa soreatis (sp. noy.): fruticosa, erecta, glaberrima; ramis aculeis in- 
fra stipularibus solitariis validis patentissimis rectiusculis armatis ; foliis parvis, pinnis 
1 —2-jugis petiolum equantibus, foliolis 4—5-jugis ovalibus vix inaquilateralibus crassius- 
culis (floribus ignotis) ; leguminibus oblongis stipitatis 2 - 4-spermis glabris margine Spar- 
sim uncinato-aculeatis, valvulis in articulos 2-4 secedentibus. — Hill-side, Upper Spring, 
on the Cimarron; August. — The specimens have ripe fruit, but no flowers. They ap- 
pear to belong to an upright shrub. The branches are armed with very stout and slightly 
hooked, scattered, infrastipular spines. The common petiole is only half an inch in 
* C. Cuamzprys (Engelm. Mss.) : “ fruticosa, humilis ; ramulis petiolisque brevibus eglandulosis pubescen- 
tibus ; foliis 2 — 3-jugis rarius 1-jugis; foliolis 6 - 12-jugis minutis ovatis obtusis seu acutiusculis supra glabris 
subtus pilosis ; stipulis subulatis rigidis erectis subpersistentibus ; capitulis breviter pedunculatis singulis binisve 
pauci- (4—8-) floris; floribus hermaphroditis; calyce campanulato subinzequaliter 5-dentato, dentibus obtusis 
pilosis ; corolla tubuloso-campanulata calyeem ter quaterve superante ad medium 5-fida extus parve pilosa 
(purpurea), lobis lanceolatis acutis subaqualibus; staminibus polyadelphis basi in tubum connatis elongatis 
tenuissimis circiter 35; ovario lineari-lanceolato suturis incrassato glaberrimo; stylo tenuissimo capillaceo 
stamina superante; stigmate capitato; legumine lineari-lanceolato stipitato acuminato (immaturo) albo-seri- - 
ceo marginibus valde inerassatis subnudo. —Chihuahua, Dr. Wislizenus, Dr. Gregg; fiowering in April. — 
Stems squarrose, much branched, 3 to 12 inches high, stout. Leaves 4 to 8 lines long: leaflets 3 to 1 line 
long. Peduncles 3 to 4 or 5 lines long. Stamens an inch long. Legume 1} to 2 inches long, } inch wide, 
white silky, while the ovary is perfectly glabrous! — The specimens of Dr. Wislizenus, from Bachimba, 
are smaller, more branched ; the leaflets smaller, obtuse, more hairy, and not more than bijugate, the lobes of 
the corolla recurved. Dr. Gregg collected in the Caiion of Ojito larger specimens, with often acutish leaflets, 
and larger flowers, with the lobes of the corolla erect. — Apparently near C. Californica and €. Xalapensis, 
Benth., but well distinguished by the very small leaflets, &e.” Engelm.
