Heterotoma Goldmanii. Annual or biennial, freely branching from 

 the base, 5 dm. high; the slender branches minutely hirsute below with 

 short hairs : leaves mostly toward the base of the plant, thin, lanceolate 

 to ovate, irregularly cut and lobed half way to the middle, 2 to 4 cm. long, 

 on slender petioles one half as long as the blade : racemes elongated, 

 slender and flexuous, pedunculate, loosely-flowered, becoming 2 to 4 dm. 

 long; pedicels filiform, spreading, at first 1 cm. long, in fruit becoming 

 5 cm. long ; bracts subulate, the lowest 1 cm. long, the upper much 

 shorter : calyx hemispherical, glabrous, in fruit 2.5 mm. long, hardly 

 equalling the lance-subulate teeth, and with a linear spur 5 mm. long, 

 bearing 2 subulate awns at the tip : corolla blue, 1.5 cm. long, the poste- 

 rior portion elongated and adnate to the spur of the calyx ; tube cleft 

 nearly to the base ; the 3 middle lobes of the limb much larger than the 

 lateral ones. — Sixaloa, road from Las Flechas to La Rostra, Feb. 22, 

 1899 (E. A. Goldman, no. 324). Nearest related to H. macrocenteron,

 more spreading inflorescence, and different leaves. 



H. stenodonta. Perennial from a slender rootstock : stems slender, 

 glabrous, 3 dm. or less high, leafy to the top : leaves ovate-lanceolate, 

 Ions-acuminate. 1 dm. or less long, 1.5 to 3.5 cm. broad, thin and slab- 

 rous, except for the entire cuneate base, sharply and irregularly serrate 

 with erect narrow-deltoid callous-tipped teeth : racemes terminal or on 

 axillary peduncles, becoming 6 or 7 cm. long; pedicels filiform, ascend- 

 ing, 1 cm. or so long, twice exceeding the subulate minutely toothed 

 bracts: calyx campanulate, the tube in fruit 3 or 3.5 mm. long, about 

 equalling the lanceolate teeth : corolla pale bluish, 8 mm. long, merely 

 gibbous at base: capsule oblong, one-half exceeding the calyx-teeth. — 

 Chiapas, Chicharras, alt. 923 to 1,847 m., Feb. 6, 1896 (E. W. Xelson,

Brickellia glomerata. Stems closely cinereous with short more or 

 less viscid pubescence, freely branched above : leaves opposite, petioled, 

 ovate to oblong, acute or bluntish, the lower excluding the petioles 8 cm. 

 long, the upper shorter, strongly rugose, scabrous above, tomentulose 

 beneath : heads sessile or subsessile in the upper axils or in terminal 

 leafy-bracted glomerules of from 2 to 5 : involucre oblong, 1 to 1.2 cm. 

 long, of about 4 series of oblong or oblong-lanceolate blunt greenish or 

 purplish-brown dark-nerved hardly scarious bracts, the outer and the 

 margins of the inner pilose or arachnoid : achenes linear, 4 mm. long,
