exceeding the lobes; upper lip oblong-ovate, entire, blunt, lower with 
two acuminate narrower lobes: corolla-tube glabrous, twice exceeding 
the calyx ; galea slightly pilose at tip, shorter than the lip. —San Luis 
Pprosi, in the mountains near Morales, 1876 (Schaffner, no. 667); 
called “ mirto grande.” Habitally this plant suggests S. fulgens, var- 
Boucheana, Benth., but it is readily distinguished by its less pubescent 
leaves, shorter calyx and slightly pilose galea. 
O O Pubescent herb with ovate obtuse leaves canescent beneath.

Described from Oaxaca. Various plants are cultivated under this 
name, but the figure above cited perhaps best represents the species. 
b. Calyx glabrous or barely puberulent at base. 
145. §. oresbia. Small shrub, 2 to 3 dm. high: branches purplish, 
puberulent in lines or glabrate: branchlets short, leafy mostly at the 
tip: leaves firm, ovate, acute at each end, appressed-serrate, glabrafe, 
1 to 2.5 em. long: racemes 1 dm. or less in length; verticels 2-4- 
flowered: bracts firm, ovate, acuminate, 1 cm. or less long, persistent: 
pedicels 3 to 7 mm. long, puberulent: calyx purpletinged, in anthesis 
1 to 1.2 cm. long, puberulent within; the tube thrice exceeding the 
broad ovate mucronate-acuminate lobes: corolla 2 cm. long; the gla- 
brous strongly ventricose tube one half longer than the calyx; the pilose 
galea hardly equalling the lip: style glabrous. —San Luis Poros, 
in the mountains, San Rafael, 1876 (Schaffner, no. 666) ; without lo- 
cality, alt. 1,850 to 2,460 m., 1878 (Parry & Palmer, no. 740). 
== = Pubescence of branches and leaves stellate. 
146. S.oaxacana. Very branching shrub: the bark pale gray, the 
young branches and branchlets white with stellate tomentum : leaves 
ovate, truncate or cordate at base, 1 cm. or less in length, pale green and 
strongly rugose above, white-tomentose beneath, crenate, one-half longet 
than the tomentose petioles: racemes 6 cm. or less long; the verticels 
mostly 2-flowered, 1 to 1.5 cm. apart : bracts ovate-lanceolate, caducous: 
pedicels 3 to 6 mm. long, glandular-pilose: calyx open-campanulate, 
glandular-pilose, in anthesis 8 to 10 mm., in fruit becoming 1.3 to 
1.5 em. long: the upper lip broad-ovate, mucronate, somewhat bidentate, 
the lower lip with 2 ovate-lanceolate acuminate lobes: corolla somewhat 
glandular-pilose; the strongly ventricose tube twice exceeding the calyx; 
the galea and lip subequal: style bearded. — Oaxaca, La Hoya Cafion, —
