FERNALD, — MEXICAN PLANTS, 567 
duncle slender, somewhat arcuate, in fruit becoming 0.5 to 1.5 em. long: 
calyx in anthesis 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, 1865 
or 1866 (Bourgeau, no. 111), 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 em. 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, — CuiApas, between Tumbala and El Salto, alt. 460 to 1,385 m., 
Oct. 29, 1895 (#. 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 em, 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 em. long: peduncle 
short, 0.5 to 1 em. 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 em. 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-angled, firm and
