LAMIACEAE 1033 



in axillary clusters, disposed in spikes, racemes or panicles. Calyx various in shape, 

 2-lipped : tube ribbed, usually glabrous in the throat or merely ciliate near the base of the 

 lobes : upper lip with 3 lobes : lower lip with 2 longer and narrower lobes. Corolla usu-

 spreading, with 3 lobes. Stamens 4, but only 2 anther-bearing, or only 2 : filaments various,

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 Gr6ggii 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 

 2-5 mm. long : calyx 10-13 mm. long ; tube many-ribbed, the upper lip acutish, the lower 

 lobes ovate, abruptly acuminate, about g as long as the tube : corolla red or purplish red, 

 2.5-3 cm. 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. 

 long : pedicels 2-6 mrn. long, slender : calyx minutely pubescent, 10-12 mm. long ; tube 

 many-ribbed, the upper lip reniform, abruptly pointed, the lower lobes ovate-apiculate : 

 corolla deep scarlet, 2-2.5 cm. long, puberulent ; tube contracted above the base, then 

 gradually enlarged, the lower lip 7-8 mm. broad, merely notched at the apex : nutlets 2.5 

 mrn. long, slightly variegated.
