abundantly and is suitable for moist spots in rock- 

 work or along streams. Some, possibly much, of the 

 material cult, as S. Cymbalaria is really the closely 

 allied -S. Huetiana. 



7. Huetiana, Boiss., frequently incorrectly offered as 

 Hutttiana. Hitftii, and Huettti (S. Cymbalaria, Hort., 

 not Linn.). Annual or biennial(?): sts. weakly erect or 

 decumbent, flaccid, 4-6 in. high: Ivs. soft, with age 

 brown-striate below; lower Ivs. reniform-cordate, 

 base cordate or truncate, broader across, 5-7-lobed, 

 lobes broad, obtuse or very shortly apiculate; upper 

 3-lobed or entire, ovate: infl. cymose with long erect 

 pedicels: fls. small but numerous, bright yellow; 

 calyx-lobes triangular, acute; petals oblong, ob- / 

 tuse, base distinctly clawed, 3 times the length of ^ 

 the calyx-lobes. May-Aug. Asia Minor. Very j ^ 

 closely allied to S. Cymbalaria and by some con- / ^ 

 sidered a variety of that species. It differs in its \, 

 dwarfer less upright habit, fewer and more obtuse \ v 

 lobes of the Ivs. and other technical floral charac- 

 ters and probably in its infl. being a cincinnus 

 instead of a bostryx. A very effective plant for the 

 rockwork. 



Section III. MISCOPETALUM. 



A. Rhizome rather thick: hs. unevenly and 



coarsely crenate or dentate 8. rotundifolia 



AA. Rhizome slender: hs. 5-9-crenate or 

 shalloi-lobed, the Its. smaller than the 

 last 9. taygetea 



8. rotundifolia, Linn. Sts. 8-12 in. high, erect from a 

 somewhat thickened rhizome, leafy and paniculate 

 from the middle or above : Ivs. rather thick, more or less 

 hairy on both surfaces; basal and lower on petioles 3-4 

 times longer than the blades, reniform or orbicular, 

 base cordate, unequally and coarsely crenate or den- 

 tate; cauline almost sessile, base obtuse or cuneate, 

 with more or less incise-dentate lobes: infl. a branched 

 panicle with long, slender glandular-hirsute peduncle 

 and pedicels; fls. white, spotted with red or purple; 

 calyx-tube very short, lobes triangular oblong, acute; 

 petals oblong-lanceolate. May, June. Eu. and Asia. 

 B.M. 424. A very satisfactory species for moist and 

 shady parts of the rockwork. Var. glandulosa, Griseb. 

 (5. glandulosa, Hort. S. lasiophytta, Schott. S. angu~ 

 losa. Schott. S. rotundifolia var. angidosa, Hort.). Sts. 

 tall, glandular-pubescent: basal Ivs. obtusely crenate; 

 the cauline Ivs. incise-dentate: the panicle branches 

 spread out and many-fld. 



9. taygetea, Boiss. & Heldr. (S. rotundifolia var. 

 taygetea, Engl.). Sts. 3-6 in. high, erect from a slen- 

 der rhizome, almost naked, pubescent: Ivs. small, 

 firm, sparse hirsute, slightly membranaceous-margined; 

 the radical Ivs. long-petioled, subcordate-reniform, 

 broadly and obtusely 5-9-crenate; the cauline Ivs. none 

 or 1 or 2 minute ones which are 3-parted or linear: infl. 

 loosely paniculate-corymbose; the branches 1-2-fld.: 

 fls. white with purple dots; calyx-lobes oblong, rather 

 obtuse; petals elliptical-lanceolate, obtuse. June- Aug. 

 Greece. Much of the material cult, under this name 

 is really 5. cuneifolia. 



Section IV. TRIDACTTLITES. 



10. adscendens, Linn. (Muscariaadscendens, Small). 

 One to 6 in. high, the whole plant viscidulous and 

 clothed with short glandular hairs: sts. erect: the basal 

 Ivs. crowded, the cauline few, cuneate, gradually 

 attenuate all the way to the base, the apex rounded or 

 truncate, 3-5-lobed, the lobes subequal, oblong or 

 ovate, rather obtuse or acutish: infl. corymbose, spar- 

 ingly branched from the middle or base of the fl.-st. 

 branches erect; fls. white: calyx glandular-pilose, tube 

 campanulate, in fr. rounded at the base and twice as 

 long as the lobes; petals cuneate, emarginate, slightly 

 5-nerved, double as long as the calyx-lobes. June, 



July. Eu. and in the Rocky Mts., S. Canada to Colo. 

 and Utah. A very common and widespread European 

 species which has not been frequently cult. 



Section V. NEPHROPHYLLUM. 



A. Basal hs. cuneate or spatulate 11. lactea 



AA. Basal hs. cordate or reniform. 



B. Infl. corymbose-paniculate 12. granulata 



BB. Infl. racemose, 1-6-fld 13. rivularis 



3556. Sazif raga Stracheyi, as the flowers are appearing in 

 earliest spring. ( X J) 



11. lactea, Turcz. Cespitose, 4-^6 in. high: sts. erect, 

 glandular-pubescent below, paniculate above: Ivs. 

 fight green, lower cuneate, 3-5^parted, lobes oblong, 

 very obtuse, horizontal -spreading; upper 3-parted, 

 lobes linear, obtuse: infl. axillary, with pedicels much 

 longer than the fls., 2-fld., the terminal fl. exceeded by 

 the lower; fls. white (milky white according to trade- 

 lists); calyx-lobes ovate, obtuse, longer than the tube; 

 petals obovate-cuneate, lightly 3-nerved, 3 times as 

 long as the calyx-lobes. June. Siberia. Probably not 

 in general cult. 



12. granulata. Linn. MEADOW SAXIFRAGE. Sts. 

 erect or ascending from a bulbiferous base, 6-20 in. 

 tall, slightly foliose, often branched below, lax panicu- 

 late, soft-hirsute, glandular-viscous above: Ivs. pilose, 

 bearing bulblets in the axils, renifonn, incise-lobed, 

 lobes entire or crenate, decurrent at base on the hirsute 

 petiole; cauline Ivs. subsessile, wedge-shaped, 3-5- 

 parted: infl. open, panicled, with glandulose elongated 

 pedicels (sometimes contracted and umbel-like): fls. 

 white, campanulate, somewhat drooping, about 1 in. 

 diam.; calyx-lobes longer than the ovate tube, linear- 

 oblong, obtuse; petals obovate-oblong, strongly atten- 

 uate at base, 3-nerved. April-June. Eu., N. Afr. 

 Gn.W. 25:513. The common meadow saxifrage of Eu. 

 and an attractive plant. The species proper is, how- 

 ever, seldom cult. Var. flore-pleno, Hort. (S. granu- 

 lata var. plena, Hort.), is the common form in cult, and 

 differs only in its double fls. G. 25: 201; 26: 213. Gn.W. 

 23:389. 



13. rivularis, Linn. Cespitose, the sts. ascending 1-3 

 in. high, more or less villous: basal lys. with petioles 

 3-5 tunes longer than the blades, renifonn, palmately 

 3-7-lobed, lobes obtuse, petioles with broad ciliate 

 stipules; upper Ivs. short-petioled, 3-lobed: infl. long, 

 peduncles arising from the axils of the lower Ivs., 

 almost as long as the whole st.; fls. at the top short- 

 pedicelled or sessile : fls. 1-5, white (often tinged purple), 

 erect; calyx short-glandular pilose or rather glabrous, 

 tube hemispherical, lobes ovate, obtuse, shorter than 

 the tube; petals obovate-oblong, twice as long as the 

 calyx-lobes. July, Aug. Circumboreal, in X. Amer. to 

 the White Mts. and in the Rocky Mts. to Mont. 



Section VI. DACTTLOIDES (MUSCARIA). 



A. Lower hs. undivided or short 3-5- 

 pointed: petals mostly small (see also 

 S. moschata and S. globulifera, which 

 have some of the hs. undivided). 

 B. Plants loosely cespitose, with indeter- 

 minate secondary shoots borne in the 

 If.-axils.
