1. Gr6ggii, Gray. Readily distinguished from the 

 common red-fld. kinds by the fact that only the lower 

 lip is showy. This is carmine, and the rest of the co- 

 rolla dull purplish. The foliage also makes it highly 

 distinct. Though a native of Texas and Mexico it is 

 offered by several dealers in hardy border plants. John 

 Saul considered it "nearly hardy" at Washington, D.C. 

 Shrub, 3 ft. high: lvs. linear-oblong, obtuse, narrowed 

 at base: racemes 2-3 in. long, C-8-fld. : upper lip short; 

 lower lip with the large middle lobe 2-lobed and 2 small, 

 roundish lateral lobes. B.M. 6812. — Section 7. 



2. spl6ndens, Ker-Gawl. Scarlet Sage. Figs. 2241, 

 2242. The most popular of all red-fld. Salvias. Tender 

 perennial herb from Brazil, 2-3 ft. high, with scarlet 

 fls. 2 in. or more long, borne in terminal pyramidal ra- 

 cemes 6 in. or more long, with 2-6 fls. in a whorl and 30 

 or more fls. in a raceme. Lvs. ovate, acuminate, serrate: 

 calyx scarlet, large, loose, plaited; corolla tubular; up- 

 per lip undivided; lower lip 3-lobed, the lateral lobes 

 much narrower andreflexed. B.R. 8:687. — Var. Brudnti, 

 Hort., int. before 1880, was an improvement over pre- 

 vious forms in having dwarf er and more compact habit, 

 with brighter and more numerous flowers. Ct.C. II. 

 14:781; III. 6:653. Gn. 21:336 (good picture). A.F. 

 5:331. Other trade names are vars. compdcta, compdcta 

 er6cta, grandifldra, grandifldra er6cta and grandifldra 

 p6ndula. Also a form with golden foliage is cult, and 

 one or more spotted with yellow. *S'. grandifldra and 

 ndna are true botanical species which are probably no- 

 where in cult., and these names in the trade mostly 

 refer to varieties of S. splendens. Var. Soucli6ti, 

 Planch. {S. Souchiti, Hort.), introduced about 1856, was 

 considered to differ from the type in having more com- 

 pact habit and fls. more numerous, more erect and more 

 brilliant. F.S. 11:1154. The prevalent idea that this 

 name is referable to S. Ecezli is probably due to a hasty 

 reading of F.S. 14, p. 32. A white-fld. form is known to 

 the trade as S. Soucheti alba. For S. ffoveyi, consult 

 S. ianthina. Var. Iss^nchou, Hort., has rosy white co- 

 rolla, calices veined red, and red anthers. l.H. 28:432 

 (as S. BrasilUnsis, var. Issanchou), where the calyx 

 is bright yellow, striped red. Gn. 21:336. There are 

 about a dozen varieties with personal names. Section 7. 



3. riitilans, Carr. A plant of unknown habitat which 

 is probably a horticultural form of S. splendens , differ- 

 ing in having a small green calyx, whorls nearly 

 always 2-fld., and inflorescence axillary as well as ter- 

 minal and panicled instead of merely racemose. R.H. 

 1873:250.-The plant figured in G.C. II. 15:117 as S. ru- 

 tilans has an unbranched raceme, with 6-fld. whorls 

 and small calyx. Offered as late as 1893 by John Saul. 



4. fulgens, Cav. Cardinal, Salvia. Mexican Red 

 Salvia. Differs from ;S'. splendens in the darker red of 

 the fls., the cordate lvs., and the calyx, which is dull 

 colored and conspicuously striate but hardlj' "colored"; 

 also the 3 lobes of the lower lip seem to be all about the 

 same size and lying in the same plane instead of hav- 

 ing the lateral ones reflexed. Mexican shrub or herb, 

 3 ft. high : lvs. ovate, cordate, somewhat acute, not acu- 

 minate. B.R. 16:135(5. — This name seems not to be ad- 

 vertised in America to-day, but in 1886 Gray stated that 

 S. splendens and S. fulgens were the two common red- 

 fld. kinds in cult. Section 7. 



5. coccinea, Linn. This name is said to be loosely 

 used in trade catalogues for S. splendens, and it is 

 doubtful whether the true S. coccinea is in cult. Per- 

 ennial or annual, 2 ft. high: lvs. cordate: fls. deep scar- 

 let, 1 in. or less long; calyx slightly reddish, lower lip 

 twice as long as upper, the middle lobe very large and 

 2-lobed. Trop. America; also S. C. to Fla. and Tex. 

 Var. Idctea, Hort., is advertised. Section 7. 



Var. Pseudo - coccinea, (^ray {S. Psendo-coccinea, 

 Jacq.), is a tall variety which is hirsute on stem and 

 petioles, instead of glalirate. B.M. 2864. 



6. Boemeri&na, Scheelo (S. porphyrdntha, Deeaisne. 

 S. porphyrdta, Hook. ) . Perennial, 1-2 ft. high : lvs. cor-
