15 lices long by 6 wide, narrowed at the base into a petiole 3 to 4 

 lines iu length : flowers 2 to 4 at each node, usually but one of each 

 group fruiting ; common peduncle none ; pedicels slender, 3 lines long : 

 calyx-teeth 5, at authesls ovate, one third as long as the tube ; fruiting 

 calyx much enlarged, bladder-like, neither angled nor conspicuously 

 veined, becoming black, 9 lines in diameter, with throat contracted 

 and teetli relatively short ; corolla campanulate, 5 lines long, with a 

 more or less spreading limb of five ovate acutish segments equalling 

 the tube, pale yellow with conspicuous dark spots in the puberulent 

 throat; filaments inserted in the middle of the short tube, half the 

 length of tlie oblong anthers : berry globular, red, much smaller than 

 the enclosing calyx ; seeds roughened, compressed, yellow. — Tama- 

 sopo Caiion, Sau Luis Potosi ; June to October, 1890 (n. 32S5). A 

 plant of puzzling affinities, possessing the habit of a Phi/salts, but hav- 

 ing a woody stem, clustered flowers, calyx without conspicuous angles 

 or veins, and anthers much exceeding the filaments. Some of the 

 characters resemble those of Athencea ; in that genus, however, the 

 fruiting calyx is much more deeply divided. 



Herpkstis auriculata. Roots fibrous; stem erect, smooth, sharply 

 4-angled, much branched above, a foot high ; branches mostly simple: 

 leaves lanceolate, acute, serrulate, sessile with an auriculate-clasping 

 base, punctate, 8 to 10 lines long, 3 lines broad ; floral leaves gradu- 

 ally reduced to linear bracts 2 to 3 lines long : flowers small, axillary, 

 mostly in pairs, opposite at each node; pedicels (iliform, 3 lines long; 

 divisions of the calyx acuminate, a line long, becoming l-^- lines long 

 in fruit, very unequal in breadth, tlu-ee of them ovate, the inner two 

 rather narrowly lanceolate, none of them at all oblong ; corolla pur- 

 plish, 3 lines long, slightly bearded within near the summit of the 

 tube ; rudimentary stamen present, very small, subulate : capsule de- 

 pressed-ovoid, suhglobose, not exceeding the calyx, 2-valved. — AVet 

 places near Guadalajara; November, 1889 (n. 2937). 



Gerardia punctata. Stem puberulent, nuich branched: leaves 

 small, numerous, opposite or appearing fascicled, linear, entire, acute, 

 smooth, 7 to 10 lines long, a line or less in breadtli ; bracts similar: 

 flowers rather numerous, opposite in long subspicate racemes ; pedicels 

 1 to 2 lines long: calyx smooth, 10-nerved, often punctate with small 

 purple dots, the five teeth lanceolate, acuminate, exceeding the tube, 

 tlie intermediate nerves terminating at each sinus in a minute glandu- 

 lar prominence ; corolla purple, tubular-campanulate, an incli long, 

 the lobes a fourth as long as the tube; stamens conspicuously didyna- 

 mous, the upper pair being much shorter and having considerably
