Setmeria SCABRA (sp. nov.) : hispldiilo-sca'bra, gracilis; foliis linearibus parvis pinnatipartitis 

 paiicilobatis superioribus 3-5-fidis integrisve ; corolla fere glabra ; antberis sagittatis, loculis 

 acutis ; capsulis glabellis ovato-acuminatis. — Mountain sides beyond tlie pass of the Limpio • 

 Wriyhf, (448.) Lower leaves wanting ; the largest seen little over half an inch in length ; the 

 segments narrowly linear 1-2-tootbed or entire. I^lowers about as large as those of S. pectinata. 

 Calyx-lobes narrowly linear. Capsule fully 4 lines long. Well marked by its anther-cells 

 tapering gradually to an acute point. 



Gerardia Wrightii (sp. nov.): caulibus e radice perenni simplicibus virgatis cum foliis 

 lineari-filiformibus mucronato-acutatis scaberrimis ; pedunculis flore £6C[uilongis; calyce truncate 

 breviter 5-dentato ; corolla flava late campanulata e tubo brevissimo extus pubescente intus 

 glaberrima; filamentis brevibus apice tantum villosis; antheris conformibus nudis obtusissimis 

 Lasi sagittatis, loculis aristato-subulatis ; stigmate clavato. — Hill sides between Babacomori and 

 Santa Cruzj Sonora ; Wright^ (14895) Bigtloio. With the habit^ calyx, and corolla of a true 

 Gerardia, sect, campaniflora), this plant has yellow flowers, (according to Mr. Wright's notes 

 taken on the spot,) naked anthers, short-awned at the base, and the filaments glabrous except 

 near the summit. The stamens are pretty strongly didynamous, and the four anthers similar,

Castilleja purpurea, Don.; Benth. in DG, Prodr. 10, p. 531. Euchroma purpurea, Nutt. 

 Texas ; Wriglity &c. Not seen on the Rio Grande, but common further north and east. Well 

 distinguished by the lower lip of the corolla, which is 2\ lines long, but not always half as long 

 as the galea. The calyx is commonly split as deeply behind as before. ^^ Bracts and calyx 

 vaiying from sulphur yellow to flesh-color, brick-red, and cherry-red, even in the same locality, 

 so that the specific name is not a good one/' {Lindheimer .') The root is perennial, 



Ca:::TILLEJA lanata (sp. nov.) : perennis, tomento floccoso simplici denso undique incana ; 

 foliis linearibus integerrimia, floralibus nunc trifidis apice coloratis ; spica demum interrupta ; 



calycis aequaliter bifidi lobis obovato-oblongis integerrimis retusisve corolke labium inferius 

 multum superantibus. — Along and near the Eio Grande, from Eagle Pass, etc., to El Paso;

) Near Buena Vista; 



Gregq. A most remarkable white-woolly species, with larger leaves and flowers than C. foliolosa. 

 The latter species is sometimes almost as white, but its tomentum is formed of repeatedly branched 

 hairs whereas the wool of C. lanata consists of long and simple arachnoid hairs. 



Castilleja tomentosa (sp. nov.) : perennis, pilis simplicibus laxis cano-lanata ; foliis linea- 

 ribus maro-ine revolutis integerrimis, floralibus trifidis superne coloratis ; spica demum inter- 

 rupta ; calycis subaequaliter bifidi lobis semibifidis lanceolatis acutis corollam aequantibus. 

 Mabibi Sonora, June, 1851 ; Thurher. Considerably like tbe last and C. foliolosa, but the 

 wool less dense and floccose tban in C. lanata, and the calyx different, and apparently fully as

long as the galea. Floral leaves aud calyx-lobes red or purple. 



Castillfja ANGUSTIF0LL4.. Euchroma angustifolia & E, Bradburii, Nutt. in Jour. Acad, 

 rinlad. T, p. 46? On Live Oak creek, the Limpio, etc., Wright, (1491, 1492, with yellow 

 bracts and calyx ;) also in his first collection, but undistributed. Mr. H. Engelmann collected 

 it at Bridger's Pass. This most likely belongs to Nuttall's species, but the lower leaves are
