 stem: fls. solitary on axillary pedicels near the top of stem.

 bell-shaped, the broad petals much exceeding 

 the calyx. Spain. B.M. 6640. Gn. 35, p. 392.

 not endure the hot climate well. An attrac- 

 tive species. 



29. caespitdsa, Linn. Exceedingly variable 

 species: dwarf and cespitose, the fl.- 



stems erect and nearly leafless and 

 somewhat glandular-pilose (3-4 in.

 usually 3-fld and some- 

 times 5-fld, the lobes 

 linear and obtuse and 

 nearly parallel: fls. 

 few, white, 1-10 in a

 pointed or lance ovate, the 3 upper ones small and in-

 Var. tricolor, Sii-b. ( S. tricolor superba, Hort.), has Ivs. 

 handsomely marked with creamy white and red varie- 

 gations. F.S. 21:2227-8 (as S. Fortunei tricolor 



i, Hook. ( B.M. fi377), is a closely allied species, 

 less i if any I sannentose, the Ivs. an- more

 lower petals are dentate. L H B 



SAXIFRAGE. See Saxifraga. 



SCABIOSA ( Latin, itch ; referring to medi- 

 cinal use). Dipsacacece. SCABIOUS. MOURN- 

 iNu BRIDE. About 52 species (from Eu., 

 Asia and Afr. ) of annual or perennial herbs, 

 often somewhat woody at the base, with en- 

 tire, lobed, or dissected Ivs. and blue, rose, 

 yellow or white fls. in mostly long-pedun- 

 cled globular or ovoid-conic heads. Bracts 

 of the involucre in 1 or 2 rows, foliaceous, 

 mostly free: scales of the receptacle small, 

 narrow or none : corolla 4-5-cleft: stamens 

 4, rarely 2, all perfect. For a related plant, 

 see Cephalaria. 



In any moderately good garden soil a 

 succession of flowers is produced from June 

 until frost. The flowers are very service- 

 able for cutting purposes. Propagated by 

 seed or division. Many of the peren- 

 nial species act like biennials in culti- 

 vation, and often flower the first year 

 from seed. S. atropur- 

 purea is a common gar- 

 den annual.
