VoL. 5] New Species of Mexican Plants. 237 
coriaceous, orbicular, spinose-toothed, 5-7 mm. in diameter, pu- 
berulent: flowers solitary in the axils of the bracts of short 
spikes: calyx 2-bracteolate, the bacteoles slightly smaller than 
the 2-mm. long bracts; lobes 5, separated to the base, lanceolate, 
7mm. long, puberulent: corolla bilabiate; upper lip erect, slightly 
2-lobed; lower lip 3-parted into broad spreading lobes; ampli- 
ated throat as long as the tube, equalling the calyx lobes: sta- 
mens 4, inserted at top of tube; sparingly hirsute; anthers, 
I-celled, dorsifixed nearly at the base, muticous, linear, pubescent 
at tips: style filiform, widened at the apex: capsule oblong, 4- 
seeded; seeds densely covered with white, branched hairs. 
This plant is not strictly congeneric with the little known 
genus Holographis, but it seems best to place it there. Collected 
at Pefia, Coahuila, growing on rocks. No. 1327. 
Carlowrightia angustifolia. Frutescent, much branched, 
minutely scabrous in two narrow, vertical lines, striate; upper 
Part, bracts and bracteoles glandular: leaves 2 mm. wide, 1 cm. 
long or less, linear, acuminate, scabrous on the upper face, margins 
revolute, ciliate near the base with a few soft hairs: inflorescence 
Spicate or rarely paniculate; corolla purple, 9 mm. long; tube 5 
mm. long; lobes oblong, obtuse, about 2 mm. wide; calyx seg- 
ments ovate-lanceolate, 3 mm. long; bracts shorter, ovate acu- 
Minate; anthers subcontiguous, muticous, one cell very slightly 
lower than the other: capsule 8-9 mm. long: the stipe half its 
length; seeds 4, white, muriculate. 
Collected near Ixmiquilpan, Hidalgo, Aug. 1905. No. 1412. 
his species is nearest to C. Pringlet. 
Stenandrium verticillatum. Many stems from a perennial

White hairs: leaves in two 4-leaved verticels, terminal and above 
the middle of the stem, obovate, attenuate into a short petiole, 
obtuse, entire, 12-15 mm. long, 7-19 mm. wide, bearing on the 
veins below and on the margins numerous white hairs: inflores- 
cence terminating the stems and axillary in a short spike from 
the lower verticel; bracts linear-laneeolate, I-2 mm long, white- 
hirsute; calyx lobes narrow, 5 mm. long, ciliate with white hairs; 
Corolla rose-colored; the tube about as long as the calyx; the
