2. S. barbatum Torr. & Gray. Very hirsute with long and shaggy white hairs: 
leaves crowded, oblanceolate, attenuate at base into an indistinct petiole, above

6. CARLOWRIGHTIA Gray. 
Much branched undershrubs, with small and narrow entire leaves, 
rather small loosely spicate or paniculate racemose purple flowers, 
small 5-parted or -cleft calyx, corolla with narrow tube shorter than the 
lobes and limb 4-parted down to the tube, 2 stamens (and no rudiments) 
nearly equaling the corolla-lobes and with equal anther-cells parallel 
and contiguous, pod on a slender clavate stipe, and very flat minutely 
scabrous seeds. 
1. C. linearifoliaGray. Ericoid-leafy: leaves filiform-linear, 8 to 16 mm. long; 
uppermost passing into similar bracts and bractlets of the somewhat paniculate 
inflorescence: lobes of the purple and almost rotate corolla 5 mm. long, twice the 
length of the tube: stipe as long as the body of the pod. (Shaueria linearifolia Torr. 
Mex. Bound.)—Mountains and cafions west of the Pecos. 
7. ANISACANTHUS Nees. 
Suffruticose or shrubby plants, with mostly lanceolate a~d entire

long) flowers, small 5-parted or -cleft calyx, corolla with elongated tube 
gradually somewhat wider at throat and 4 similar entire erectish re- 
curving lobes, 2 stamens (and no rudiments) equaling or exceeding the 
corolla-lobes and with equal anther-cells parallel and contiguous, pod 
on long clavate stipe, and smooth or rugulose seeds. 
* Calyx-lobes attenuate, longer than the stipe and mostly about equaling the body of the 
pod: corolla dull red, funnelform above: flowers chiefly in axillary and mostly leafy 
Sascicles. 
1. A. Thurberi Gray. Shrubby, 6 to 12 dm. high: young parts minutely hirsute: 
leaves oblong or lanceolate, 2.5 cm. or less long, subsessile (Drejera Thurberi and D. 
puberula Torr, Mex. Bound.).—Mountains of western Texas. 
* * Calyx shorter, not surpassing the stipe of the pod: flowers usually (at least the upper 
ones) spicately or racemosely disposed along the branchlets and secund, 
2. A. insignisGray. Puberulent or nearly glabrous: leaves mostly linear-lanceo- 
late to linear: flowers pedicellate, in lateral clusters from axils of fallen leaves and 
short-racemose on evolute small-bracted branchlets: calyx puberulent-glandular: 
corolla rose-red or even salmon-color, 5 cm. long: stipe when well developed longer 
than the body of the pod. (A. pumilus Wats., Proc. Am. Acad. 18, not Nees. Dre- 
jera puberula Torr. Mex. Bound. as to pl. Gregg.)—Chisos Mountains on western 
borders of Texas (Havard). 
8. A. Wrightii Gray. Puberulent or the foliage glabrous, 6 to 12dm. high: leaves 
oblong or ovate-lanceolate, acute or acuminate: spikes loosely paniculate, naked:
