FERNALD, — MEXICAN PLANTS. 567 



duncle slender, somewhat arcuate, in fruit becoming 0.5 to 1.5 cm. long: 

 calyx in authesis 3 or 4 mm. long, sparingly pilose, with 5 short deltoid 

 ciliate lobes : corolla campanulate-urceolate, 7 to 10 cm. long, nearly as 

 broad, sulphur-yellow, with purple patches at base : fruiting calyx gla- 

 brate, globose, 1 to 1.5 cm. in diameter, the short calyx-tips closely con- 

 nivent. — Mexico, borders of ditches. Valley of Mexico, July 10, 18G5 

 or 1866 {Bourgeau, no. Ill), Valley of Mexico, alt. 2,250 m., Oct. 4, 

 1899 (C. G. Pringle, no. 8215). A much coarser plant than the similar 

 M. solanaceus, with larger yellower corolla. 



Athenaea Nelsonii. Stems petioles and pedicels glandular-villous, 

 fuscous : leaves solitary or geminate and very unequal, on petioles 8 cm. 

 or less in length, broadly ovate, acuminate, equally or unequally cordate 

 at base, entire, undulate or slightly sinuate-toothed, the larger 2 dm. long, 

 thin, dark green and minutely pubescent above, pale and appressed-pilose 

 beneath, especially on the nerves : flowers in fascicles of 5 to 15 : pedi- 

 cels at first rather short, in fruit becoming 2 to 3 cm. long : calyx thin, 

 glandular-pilose, short-campanulate, in anthesis 5 to 6 mm. high and 

 broad, rounded or subtruncate at base, the tube hardly equalling the 5 

 deltoid lobes: corolla yellowish, 1.5 to 2 cm. long, deeply cut into oblong 

 ciliate lobes 1 cm. long : filaments broad at base, inserted midway up the 

 throat of the corolla, rather shorter than the oblong anthers (3.5 to 4 mm. 

 long) : fruiting calyx becoming 1 cm. in diameter, inclosing the scarlet 

 berry. — Chiapas, between Tumbala and El Salto, alt. 460 to 1,385 m., 

 Oct. 29, 1895 {E. W. Nelson, no. 3395). A large-leaved species habit- 

 ally resembling A. viscosa, Benth. & Hook. (^Saracha viscosa, Schrad., 

 Sweet, Brit. Fl. Gard. ser. 2, t. 323), but with smaller more regular 

 calyx, more deeply lobed corolla and much shorter filaments. 



Physalis subintegra. Perennial from a very slender root-stock 3 

 or 4 dm. long, ascending, slightly branching from near the base : stems 

 tough, dark green, sparingly appressed-pubescent with simple hairs or 

 glabrate, about 3 dm. high : leaves from ovate-lanceolate to broadly ovate^ 

 3 to 6 cm. long, 1.5 to 3 cm. broad, entire or slightly repand-dentate, 

 somewhat appressed-pubescent on both surfaces, tapering above to a blunt 

 tip and slightly rounded below to a petiole 0.5 to 2 cm. long: peduncle 

 short, 0.5 to 1 cm. long : calyx in anthesis 7 to 10 mm. long, pubescent, 

 with triangular-lanceolate or ovate acute lobes : corollas pubescent with- 

 out, the earlier 2.5 cm. broad, the later smaller, sulphur yellow with 

 large dull brown markings at base : one filament slightly exceeding the 

 others, 5 mm. long; anthers oblong, purplish, 2 or 3 mm. long: fruiting 

 calyx globose-ovoid, a little sunken at base, slightly 5-augled, firm and
