Subsection BRACHYANTILE. 



27. azurea, Lam. (S. acuminata, Michx., not Cav.). 

 Perennial, 1-6 ft. high: sts. herbaceous, erect, glabrous: 

 Ivs. petiolate, oblong-lanceolate or linear, rather obtuse 

 or acute, base long-narrowed, somewhat serrate, both 

 surfaces green and glabrous; floral Ivs. lanceolate-linear, 

 deciduous: racemes simple, elongated; floral whorls 

 distant, about 6-fld.; calyx green or bluish, subsessile, 

 tubular, striate, the 3 teeth broad, rather acute; corolla 

 blue. Aug. S. C. to Fla. and Texas. B.M. 1728. Var. 

 grandifldra, Benth. (S. Pitcheri, Torr.), which differs 

 in being cinereous-puberulent, in its denser infl. and 

 tomentulose-sericeous calyx. G.C. II. 14:685. Gn. 

 19:600; 61, p. 309. G.Z. 26:121 Probably the plant 

 formerly offered as S. Pitcheri var. angustifolia, Hort., 

 belongs here. It is quite probable that some of the 

 material in the trade as S. azurea var. grandiflora is in 

 reality S. farinacea. Var. grandiflSra filba, Hort. (S. 

 azurea var. alba grandiflora, Hort.), is a white-fld. 

 form of the variety. 



28. farinacea, Benth. Perennial, 2-3 ft. high: st. 

 herbaceous, erect, tomentose: Ivs. petiolate, ovate- 

 o.blong, or lanceolate, rather obtuse, irregularly serrate- 

 crenate, rather glabrous, both surfaces green or the 

 lower canescent; floral Ivs. small, deciduous: racemes 

 elongated, simple; floral whorls many-fld., subsecund, 

 remote or the uppermost approximate; calyx subsessile, 

 tubular, purplish colored, densely white-lanate; corolla 

 purple or violet, the tube scarcely exserted. Summer. 

 Texas, where it is reported as growing in rich soil. Gn. 

 9:430; 28, p. 59; 78, p. 226. R.H. 1873:90 A showy 

 frequently cultivated species, the fls. quite attrac- 

 tive, the darker corollas being set off by the mealy 

 lighter violet-white calices. Var. alba, Hort., is a 

 white-fld. form with the midlobe of the lower corolla-lip 

 obcordate, 2-lobed. 



29. uligindsa, Benth. Sts. herbaceous, erect, 2-6 ft. 

 high, virgate, branched, glabrous or villous: Ivs. 2-4 

 in. long, petiolate, oblong-lanceolate, acute, serrate, 

 base narrowed, glabrous or pubescent; floral Ivs. 

 membranaceous, broad-ovate, acuminate, deciduous: 

 racemes dense, long-peduncled, somewhat branched; 

 floral whorls many-fld.; calyx campanulate, variable, 

 sometimes colored; corolla blue or white, tube some- 

 what or nearly included. Brazil, Argentina, and Uru- 

 guay. B.M. 8544. Gn. 77, p. 484. G.M. 56:711. 

 R.H. 1912, p. 469. 



30. amarissima, Ort. Perennial, about 2 ft. high: 

 sts. herbaceous, erect, branched, pilose-hispid: Ivs. 

 petiolate, ovate-cordate, crenate, canescent below; 

 floral Ivs. ovate, acuminate, deciduous : racemes simple, 

 densely fld.; floral whorls distinct, subremote, about 

 10-fld.; calyx tubular-campanulate, striate-villous, the 

 3 teeth rather acute; corolla blue. Aug. Mex. B.R. 

 347. Probably rare in cult. 



Subsection ERIANTHJE. 



31. leucantha, Cav. Fig. 3535. Shrub, about \V~2, 

 ft. high: st. shrubby, with elongated branches which are 

 subterete, and white-lanate, the wool finally caducous: 

 Ivs. short-petioled, lanceolate-linear, acute, crenate, 

 base rotundate, pubescent and rugose above, white- 

 lanate beneath; floral Ivs. ovate, acuminate, deciduous: 

 raceme elongated, often purplish, 6-10 in. long; floral 

 whorls many-fld., the lower remote; calyx subsessile, 

 ovate, densely lavender- or violet-lanate ; corolla white, 

 white-lanate outside. June. Mex. B.M. 4318. Gn. 

 21:328. Probably not very common in cultivation, at 

 least in N. Amer.
