S. prunelloides, HBK. (no. 40 of the writer’s synopsis), but differing 
from that and the other members of the group in its tall erect stem. a 
S. (Vulgares) igualensis. Tall (1 m. or more high), the strouzly — 
grooved quadrangular stem canescent with close pubescence: leaves, 
broad-ovate, the lower suborbicular, short-acuminate, rounded at base, \ 
5 to 7 cm. long, 4 to 5.5 cm. broad, coarsely crenate-serate, minutely 
puberulent or glabrate on both faces, pale beneath, on slender canescent 
petioles 1 cm. or less in length: racemes long and slender, becoming 1.5 
to 2 dm. long; verticels 10-20-flowered, mostly approximate, the lower 
1.5 cm. apart; bracts lanceolate, caducous; pedicels becoming 2 mm. 
long: calyx in anthesis about 8 mm. long, short-pilose-hispid on the 
nerves, with short deltoid teeth; corolla blue, pilose, 1 cm. long; the 
slightly ventricose tube twice exceeding the calyx; galea and lip sub- 
equal: style bearded. — GuERRERO, limestone mountains above Iguala, 
alt. 1,230 m., Sept. 26, 1900 (C. G. Pringle, no. 8418). Related to 
S. brachyodonta, Brig. (no. 59 of the writer’s Synopsis) and S. Ghies- 
breghtii, Fernald (no. 60). From the former distinguished by its coarser 
habit, cinereous stem, short petioles and appressed teeth of the leaves, 
and shorter. pedicels; from the latter by its coarser habit, and broader 
glabrate leaves without the characteristic lanate pubescence of S. 
Ghiesbreghtit.

closely matted simple hairs: leaves oblong or oblong-ovate, 2 to 4 cm.

above, canescent beneath with close simple hairs ; petioles slender, 1.5 cm. 
or less long: racemes becoming 1 dm. or so long, simple; verticels 
8-12-flowered, the lowest 1 to 1.5 cm. apart; pedicels at most 1 mm. 
long: calyx cuneate-campanulate, canescent with short mostly simple 
appressed hairs, in anthesis 7 mm. long, with short flaring blunt oF 
merely short-subulate lobes: corolla 1.5 em. long, pubescent with short 
gland-tipped hairs. — Guanasuato, Aug., Sept., 1900 (A. Duges)- 
This plant, known as “Ohia cimarona,” is nearest related to S. lasiantha, 
Benth. (no. 104 of the writer’s Synopsis), but is distinguished by its 
narrow leaves, shorter pubescence throughout, larger calyx, and by the 
pubescence of the corolla, which in S. lasiantha is pilose and essentially 
ess.
