 but those in cultivation are hardy perennials, being 

 recommended for the herbaceous border.

 showy, pink, purple, or white, in terminal racemes or 

 spikes, mostly without bracts or involucels beneath; 

 stamens united into groups in a double series: carpels 

 5-9, reniform, separating at maturity. About 30 

 species, natives of W. N. Amer. For monograph, see 

 Gray, Syn. Fl. N. Amer., vol. 1, p. 302. Of easy cult.

 crenate, the upper ones 5-cleft or 5-divided, segms. nar- 



row and entire or broader and pinnate-lpbed : fls. 2 in. 

 or less across when fully expanded, purple. Calif. H.U. 

 2, p. 65 (as Nuttallia malv&flora). Var. atropurp&rea, 

 Hort. (S. atropurpurea, Hort.), grows 2-3 ft. high, with 

 large, open, purple fls. Var. Listeri, Hort. (S. Listen, 

 Hort.), known also as "pink beauty," has satiny pink 

 fls. It is of European origin. 



neo-mexicana, Gray. One to 8 ft. high: sts. hirsute- 

 pubescent, more or less branched: radical Ivs. orbicu- 

 lar, 5-9-lobed or incisely crenate; cauline Ivs. parted, 

 segms. 3-lobed: raceme many-fid.: fls. rose; calyx hir- 

 sute: carpels smooth and glabrous. Mountains of New 

 Mex. and Ariz, northward to Wyo. 



campestris, Greene. Two to 5 ft., often branching 

 above, glabrous or sparingly hirsute-pubescent: Ivs. 

 green, the lower ones rounded and variously lobed, 

 the upper ones 5-7-parted into narrow divisions: fls. 

 about \]/2 in. across, in strict spike-like racemes, pur- 

 plish, the petals often laciniate. N. Calif, to Brit. Col. 



oregana, Gray. Less hairy than S. campestris, the 

 racemes becoming branched and paniculate: fls. 

 smaller. Ore. and Wash. 



The following are offered in the trade, but unknown botanically:

 cana, Hort., a strong grower, 3 ft. high, with satiny rose fls. borne

SIDERITIS (Greek, iron; the plants were supposed to 

 have a healing power for wounds caused by iron. Dios- 

 corides also used the name for other plants credited with 

 the same ability). Labiate. Herbs, subshrubs, or 

 shrubs frequently lanate or softly pilose, mostly hardy 

 or half-hardy but some of them coolhouse plants: Ivs. 

 entire or toothed, the floral ones reduced to bracts or 

 similar to the lower cauline: fls. in axillary clusters of 

 6 to many fls. or in interrupted or dense spikes, small, 

 often yellowish; calyx tubular, 5-10-nerved, with 5 

 erect somewhat spiny teeth, or rarely muticous; corolla- 

 tube included, bare or with a pilose ring inside, the limb 

 2-lipped, the posterior somewhat flat, entire, emargi- 

 nate or 2-cleft, the anterior spreading, 3-cleft; 

 stamens 4, didynamous: nutlets ovoid, smooth, 

 obtuse, not truncate at the top. About 60 

 species, Medit. region, Canary Isls., and the 

 Orient. Probably the commonest is S. scordi- 

 oldes, Linn., a hardy subshrub, about 1 ft. 

 high, with ovate, oblong, or oblong-linear, 

 incised-toothed Ivs., spikes which are 1-3 in. 

 long of yellowish fls. with the upper lip of the 

 corolla paler or white. S. Eu. Variable . 



Other species which have been mentioned are: S. 

 canaritnsis, Linn. A greenhouse shrub several feet high, 

 with ovate, crenate Ivs. which are cordate at the base, 

 and subglobose whorls of 20-30 fls. Canary Isls. S. 

 cdndicans, Ait. A greenhouse shrub about 3 ft. high, 

 covered with white wool, with ovate Ivs. which are 

 truncately cordate at the base, whorls of about 10 sub- 

 sessile fls., the lower ones distant. Madeira and Canary 

 Isls. S. incana, Linn. A half-hardy subshrub about 

 1 ft. high, with white-woolly branches, sessile, oblong- 

 linear, obtuse, white-woolly Ivs. and distant whorls of about 6 fls. 

 Spain. S. perfolidta. Linn. A half-hardy subshrub about 1-1 Yi ft. 

 high, with half-clasping, ovate-oblong or lanceolate softly villous 

 Ivs. and distant whorls of sessile fls. S. Eu. S. taiirica, Willd., is 

 a half-hardy shrub about 1 }/i ft. high with thick oblong-lanceolate 

 or spatulate Ivs., the lower ones crenulate, densely white-woolly.

SIDEROXYLON (Greek, iron and wood, referring to 

 the hardness of the wood) . Sapotaceas. Trees and shrubs,

 ovate, usually obtuse, nearly equal ; corolla more or less 

 bell-shaped; stamens attached to the tube at the base of 

 the lobes and opposite to them; staminodia scale-like or
