obtusish, entire or subrepand, ciliate, strigose-pubescent upon either sur- 

 face, and hirsute upon the midrib and veins beneath, abruptly contracted 

 below into a narrowly winged petiole ; petioles 5 to 22 mm. long, hirsute- 

 pubescent : inflorescence extra-axillary of 1 to 4 slender reflexed pubescent 

 pedicels, becoming in fruit about 2 cm. long : calyx deeply 5-parted, 

 densely covered with a long spreading hirsute pubescence ; divisions 

 linear-oblong, acute, 3 to 7 mm. long, more or less persistent : corolla 

 about 1 cm. in diameter ; lobes broadly ovate, short-pubescent at the 

 acute apex, externally covered with a few long scattered jointed hairs : 

 stamens 5, equal; anthers oblong: ovary glabrous, 2(-4)-celled : fruit 

 smooth, about 8 mm. in diameter ; seeds oblique-ovate, corrugated, 3 mm. 

 long. — Collected by Lucius C. Smith, at Cuicatlan, 15 July, 1895, 

 no. 403 ; E. W. Nelson, between Topana, Oaxaca, and Tonala, Chiapas, 

 altitude 61 to 150 m., 1-3 August, 1895, no. 2876^; and by C. G. Prin- 

 gle, on shaded hillsides near Cuernavaca, altitude 1,500 m., 26 July, 1896, 

 no. 6400. A species apparently well characterized by the infloresce ce, 

 calyx, and pubescence. Most nearly related to the Solanum nigrum 

 group. 



Solanum Mitlense, Dun. Specimens agreeing in all detailed char- 

 acters with the original description of the above species were collected 

 in the State of Oaxaca by Lucius C. Smith in the Calderon, San Juan

 Oaxaca, altitude 1,540 to 1,600 m., 8 and 24 September, 1894, no. 1234; 

 by C. G. Pringle, in ravines of hills near Oaxaca, altitude 1,750 m., 

 15 September, 1894, no. 4907; and by C. Conzatti and V. Gonzalez, 

 about the city of Oaxaca, altitude 1,550 m., 2 April, 1896, no 98. From 

 Mr. Prino-le's full and careful notes, the following additional characters 

 may be given. Entire plant 3 to 4^ m. in height, tree-like in habit ; 

 trunk 2 to 2^ m. high, 1 to 2 dm. in diameter, trichotomously branched 

 above, covered with a grayish brown bark, stout spines, and a scattered 

 stellate pubescence : mature fruit green, globose, about 2 cm. in diameter : 

 seeds 3 mm. long, oblique, compressed and scrobiculate. 



Dicliptera Pringlei. Annual, herbaceous, 5 to 8 dm. high : roots 

 fibrous : stems hexangular, somewhat farrowed, lineolate, puberulent 

 upon the angles, swollen or constricted just above the nodes : leaves 

 ovate to ovate-lanceolate, acuminate, acute, narrowed below into a slen- 

 der petiole, entire, ciliate, lineolate with a few scattered hairs on either 

 surface ; petioles pubescent, 2\ to 'dh cm. long, becoming gradually 

 shorter above : inflorescence much branched, open: heads on long slen-
