SAXIFRAGA 



SCABIOSA 



3105 



of dark green foliage and stout sprays of clear yellow 

 fls. resembling S. Boydii. 



134. Haagei, Sunderm. (S. sdncta x S. Ferdindndi- 

 Cbburgi). This more nearly resembles the latter parent. 

 Its habit is very compact, its foliage is similar and glau- 

 cous: fl.-sts. 2-3 in. high, bracted, tinged red-brown 

 and glandular-hairy: fls. golden yellow, 4-5 to a St., 

 clustered in heads." March, April. A garden hybrid. 

 Gn. 78, p. 170. 



135. Godseffiana, Hort., also known as S. Godseffi 

 and S. L. S. Godseff (S. sdncta xS. Elizabeths). Habit 

 of growth intermediate, foliage spiny and in close tufts: 

 fl.-sts. 3-4 in. high, reddish and having reddish green- 

 tipped Ivs. : fls. an improvement on S. Elizabeths, being 

 deeper yellow and having better form. A garden hybrid. 



S. atrorirens, Hort., is offered in the trade as a form growing 6 in. 

 high, with white fls. Probably belongs in Section Dactyloides. S. 

 Bakeri, Hort., is one of the smaller mossy saxifrages with vivid green 

 foliage, a plant of compact habit with rich carmine or rose fls Prob- 

 ably belongs in Section Dactyloides. S. B&ykei, Hort., is offered in 

 the'trade. S. capillaris, Hort.. is offered in the trade as a white-fld. 

 species. S. carniolica, Hort., is offered in the trade and said to 

 have white fls. 5. caryophyUa, Hort., is offered in the trade as one 

 of the easiest to grow, fls. white. Perhaps a misspelling of corio- 

 phylla, which is a variety of S. Rocheliana. iS. circuenta, Hort., is 

 said to have silvery braided foliage and pretty little panicles of white 

 fls. borne on sts. 4 in. high. It belongs to Section Euaizoonia. ^S. 

 cristata hybrida, Hort., is offered in the trade as a form growing 6 in. 

 high, with white fls. Probably a form of S. Aizoon near var. para- 

 doxa. 5. elatior, Mert. fc Kpch=S. Hostii. S. elatior, of German 

 authors=S. altissima. S. elatior, Wimm.=S. Aizoon var. major. 

 S. Ganolini, Hort., is offered in the trade as growing 6 in. high with 

 white fls. S. H&tcortMi, Hort., forms cushions of rather pale 

 green, about 6 in. high, the growth being packed and somewhat 

 rounded at the top: fls. pure white and numerous. Probably belongs 

 in Section Dactyloides. S. Hectori, Hqrt., is offered in the trade. 

 S. hybrida, Hort., not others=S. decipiens.-pS. hybrida, Haw.=S. 

 hypnoides. S. incurrifolia, Hort., not Don, is listed as belonging to 

 the encrusted section and as having white fls. S. incurrifolia, Don, 

 is a variety of S. eespitosa. S. tieris, Hort. (?) of Bieb. and of Oet- 

 tingen. The plant in cult, under this name belongs to Section 

 Trachyphyllum and has a spreading habit like S. aizoides with loose 

 rosettes of narrow elliptic-oval Ivs.: fl.-sts. about 2 in. high, tinged 

 crimson below and bearing each 4-6, not large, rich yellow fls. Cau- 

 casus. Requires a moist situation. S. teens, Bieb., also from Cau- 

 casus, is placed in Section Kabschia by Engler, but by several other 

 authors is said to be close to S. Aizoon or S. aizoides and may be the 

 same as the plant in cult. ; if not the one now grown as S. laevis must 

 receive a new name. S. Iseris, Oettingen, seems to be the same as 

 that of Bieb. as far as the description is concerned; the plants have 

 not been seen. S. leans, Hort., is offered in the trade as a very com- 

 pact form, 6 in. high, with white fls. Probably belongs in Section 

 Dactyloides. S. Lindesidna, Hort., also spelled Lindisiana, is of- 

 fered in the trade as a mossy species with white fls. Perhaps belongs 

 in Section Dactyloides. S. linaueformis, Hort., is offered in the 

 trade. . palmata, Hort., is uncertain and seems to be sometimes 

 S. decipiens. sometimes S. geranioides. Var. foliis tariegatis is a va- 

 riety of one of these species with variegated foliage. S. paradoxa, 

 Hort., is described in a trade-list as a beautiful member of the Aizoon 

 group with long and "braided" foliage. Presumably a natural 

 hybrid between S. crustata and S. Hostii. Considered by some as a 

 variety of S. Aizoon, which see. S. paradoxa, Kit.=S. moschata 

 var. pygmsea. -S. pectinata, Pursh=Luetkea pectinata, Kuntze. 

 S. pedatifida, Hort., is offered in the trade as a white-fld. species. S. 

 Pseudo-Fosteri, Hort., is offered in the trade as a hybrid of the 

 encrusted section. Var. sdncta, Hort., is offered in the trade as an 

 early yellow-fld. form. S. pyrolifolia, Don=Leptarrhena pyroli- 

 folia, R. Br. S. Ringtana, Hort., is offered in the trade as a dwarf 

 plant of spreading habit, growing 4 in. high and having white fls. 

 Probably belongs in Section Dactyloides. S. rupestris, Lapeyr.= 

 S. ascendens. 5. rupestris, Salisb.=S. hypnoides. Which of these 

 the material offered in the trade as a very compact plant 

 growing 6 in. high, with white fls. cannot be determined with cer- 

 tainty, though probably the second as it is said to belong to 

 the mossy section. iS. Schroederi, Hort., is offered in the trade 

 as allied to S. ceratophylla which is a variety of S. trifurcata, 

 a species of Section Dactyloides. S. seiemifida, Hort., is offered 

 in the trade. 5. Sibthorpii, Boiss. Fig. 3558. Of the Cymbalaria 

 group: perennial, cespitose, with renifonn long-stalked obtuse- 

 Ibbed Ivs. and small yellowish fls.: petals ovate-elliptic. A good 

 rock-plant, but seems not to be in the trade. S. Stansfieldi, Wm. 

 Robinson, is said to have a close-growing habit, dark green 

 foliage and white fls. borne on sts. 4 in. high. Perhaps it 

 belongs in Section Dactyloides. S. stellata, Hort., not. Pav., 

 is offered in the trade as a white-fld. mossy plant, 1 ft. 

 high. This is unquestionably not the stellata of Pavon which 

 is the Peruvian representative of S. eespitosa and grows scarcely 

 1 in. high. 5. stenoglossa, Tausch. Lvs. of the rosette rather 

 erect, cuneate or cuneate-linear, acute, serratures narrow, the 

 lower ones spreading, the uppermost contiguous, with the terminal 

 tooth slightly protruding. A plant is offered under this name, but 

 whether the same as the indeterminable Tausch species it is impos- 

 sible to say. The above given description is a translation of the 

 original of Tausch. S. Taniians, Hort., is offered in the trade. S. 

 taxiophyUa, Hort., is offered in the trade as a white-fld. species. Var. 



persifolia, Hort,, is also offered. 5. tenuifolia, Hort,, is offered in 

 the trade as growing 6 in. high, with white fls. Probably belongs in 

 Section Dactyloides. S. Van Hoitttei, Hort., is offered in the trade. 

 It belongs to Section Bergenia and has light pink fls. 5. tenetica, 

 Hort., is offered in the trade as a species with minute tufts and prim- 

 rose-yellow fls. belonging in the encrusted section. S. Webbiana, 

 Hort., is offered in the trade. Possibly belongs in Section Dacty- 

 loides. T- T T I

SCABIOSA (Latin, itch, referring to medicinal use). 

 Dipsacaceae. SCABIOUS. MOUBNIXG BRIDE. Annual or 

 perennial herbs, their base more or less woody, com- 

 prising some of the showy and commonly cultivated 

 garden flowers. 



Leaves entire, dentate-lobate or dissected: heads 

 terminal, depressed subglobpse or ovoid-conical, 

 pedunculate or rarely sessile in a dichotomous infl.; 

 bracts of the involucre 1-2-rowed, herbaceous: fls. blue, 

 rose, yellowish, or white; calyx bristly; corolla-limb 

 4-5-cleft, subequal or frequently oblique or 2-lipped; 

 stamens 4, very rarely 2: achene adnate to the involucel 

 at the base or up to the middle. About 70 species, Eu., 

 Asia, and Afr., rare in the tropics. 



In any moderately good garden soil a succession of 

 flowers is produced from June until frost. The flowers 

 are very serviceable for cutting purposes. Propagated 

 by seed or division. Many of the perennial species act 

 like biennials in cultivation, and often flower the first 

 year from seed. S. atropurpurea is a common garden 

 annual, of easy cultivation from seed.
