subbilaliata, labio superiore integro vel vix emarginato, labiis oblongis æqualibus, labio infe- 
riore profunde trifido; antherarum loculis parallelis contiguis muticis. Mountains and rocky 
places on the Cibolo ofthe Rio Grande; August; Bigelow. Monterey, Nuevo Leon ; Dr. Edwards, . 
Dr. Gregg. Howard Springs; Scho't. (No. 1460, Wright. No. 1459 js an early state of the 
same, in which the flowering branches or spikes are not developed.) At Oak creek, western 
Texas, Mr. Schott collected specimens with larger and almost orbicular obscurely repand leaves. 
They probably grew in a shady place. Plant 6-12 inches long, sometimes diffuse. Leaves } 
to 1 inch in length, abruptly narrowed to a petiole which is 3 to 6 lines long. Flowers in 
loose compound spikes or panicles terminating the branches. Segments of the calyx subulate. 
Corolla 4-5 lines long ; the segments nearly equal and about as long as the tube. Capsule 5 
lines long, the lower half abruptly contracted and stipe-like; the upper part orbicular-ovate, 
acuminate, smooth, 4-seeded. Seeds discoid, muriculate, black. 
SCHAUERIA LINEARIFOLIA (n. sp.:) suffruticosa e basi ramosissima glaberrima ; foliis angusto- 
linearibus ; spicis terminalibus gracilibus paniculatis, floribus distantibus, bracteis bracteolisque 
subulatis ; calycis laciniis lanceolato-subulatis, corolla (purpurea) subbilabiata laciniis oblongis 
subeequalibus ; antherarum loculis parallelis contiguis muticis. Rocks at the mouth of the 
Great cañon of the Rio Grande, and on the Burro mountains; June—October; Bigelow, 
Parry. (No. 436, Wright.) About a foot high. Leaves 8-10 lines long; the lowest ones a 
little broader and somewhat spatulate; upper ones half aline wide. Flowers solitary in the 
upper axils, the leaves being gradually reduced to subulate bracts, so that the inflorescence 
becomes spicate. Calyx, corolla, and fruit, as in the preceding species. 
DREJERA+ WRIGHTII (n. sp.) ramis bifariam pubescentibus ; foliis oblongo-lanceolatis acumi- 
natis glabris, spicis unilateralibus nudis ; calyce glanduloso-pubescente profunde 5-fido, laciniis 
` oblongo-lanceolatis ; corollee tubo angusto calyce multoties longiore, labio inferiore tripartito, 
laciniis lanceolato-linearibus. Between the Guadaloupe river, Texas, and the Rio Grande; 
also near Monterey, Nuevo Leon; June—October. Nos. 435 and 1457, Wright. Plant appa- 
rently 3 to 4 feet high ; dull grayish green; the branches terete, marked with two broad lines 
of soft pubescence. Leaves 11-2 inches long, and 6-8 lines wide ; green on both sides; the 
petiole 3-5 lines long. Spikes terminating the paniculate branches. Bracts about as long as 
the very short pedicels. Corolla an inch and a half long; purplish red; the tube slender, 
inflated at the base, the enlarged portion about the length of the calyx ; segments of the upper 
lip a line and a half wide; upper lip emarginate. Anther-cells linear, contiguous, parallel. 
Capsule smootb, 6—7 lines long, the upper half rhombic-ovate and semeniferous; the lower 
attenuated to a narrow stipe and empty. Seeds commonly 2, rarely 3 or 4, lenticular, smooth. 
DREJERA PUBERULA, (n. sp.): ramis bifariam pubescentibus; foliis oblongo-lanceolatis vel 
lineari-lanceolatis puberulis brevipetiolatis ; spicis brevibus axillaribus terminalibusque foliosis ; 
calyce glanduloso-pubescgmte profunde 5-fido, laciniis lineari-subulatis ; corolla: tubo angusto 
calyce multoties longiore, labio inferiore tripartito, laciniis lanceolato-linearibus. Gravelly 
hills and ravines along the Cibolo of the Rio Grande; May—June; Bigelow. No. 1456,

merely extending the character as to the calyx, which is 5-cleft or 5-parted. It includes Drejera, Mees, and Jacobinia S 2 of 
the same author in DC. Prodr. The latter genus was founded on J. lepida, and is the only species referred by Nees, to his first 
section. It differs so much from the species of the second group, which we would transfer to Drejera, that it may remain by
