1. Salvia Roemeriana Scheele. Perennial, closely pubescent and more or less hir- 
sute. Stems erect, 3-7 dm. tall: leaf-blades ovate, suborbicular or reniform, 2-4 cm. 
broad, the lower ones often compound, the leaflets then similar to the blades of the 
upper leaves, all repand-angulate, truncate or cordate at the base, slender-petioled : 
panicles 1-3 dm. long, the clusters few-flowered : pedicels 2-7 mm. long: calyx finely 
pubescent and somewhat glandular, 8-10 mm. long, the upper lip destitute of a middle 
tooth, the lower lobes lanceolate, acuminate: corolla scarlet-red, 2.5 cm. long; tube 
slightly curved, the lower lip with a broad cleft middle lobe, its lateral lobes rounded : 
nutlets 2 mm. long, granular. 
In light soil, Texas. Spring and summer. 
2. Salvia Gréggii A. Gray. Perennial, more or less puberulent. Stems erect, 
several dm. tall, branched : leaf-blades firm, oblong or nearly so, 0.5-1.5 cm. long, obtuse, 
nearly veinless, short-petioled : panicles 2-10 cm. long, the clusters few-flowered : pedicels 
mm. long : calyx 10-13 mm. long ; tube many-ribbed, the upper lip acutish, the lower 
lobes ovate, abruptly acuminate, about 4 as long as the tube : corolla red or purplish red, 
2.5-3 em. long ; tube saccate beneath, the upper lip concave, notched, glandular-pubescent 
on back, the lower lip with a middle lobe 1.5 cm. broad, this cleft into 2 rounded seg- 
ments with a slender tooth between them : style pubescent on top : nutlets 3 mm. long. 
In valleys, southern Texas. Spring and summer. 
3. Salvia coccinea L. Annual or perennial, softly pubescent. Stems erect, 3-7 
dm. tall, simple or sparingly branched : leaf-blades ovate or deltoid-ovate, 3-6 cm. long, 
obtuse or acutish, crenate-serrate, truncate to subcordate at the base: panicles 5-20 cm.
