SENECIO SIDERITIS. 



yellow, very closely-set, in simple 

 corymbs ; scales of involucrum woolly, 

 obtuse and marked on the end with 

 a black spot. Leaves, pinnatifid ; lobes 

 linear, obtuse, slightly toothed. 



South of France. The rock-garden, 



in sandy or gritty well-drained soil. 

 Division. 



Senecio uniflorus (One-flowered &.) 

 A very dwarf silvery species about 

 1 in. high. Flowers, in summer ; 

 small, insignificant, yellow; scales of 

 involucrum acute, downy, marked 

 with a black spot on the end. Leaves, 

 lower ones oblong, toothed or cut, 

 narrowed into a footstalk ; upper 

 ones sessile, linear ; whole plant 

 covered with a white down. Swiss 

 and Piedmontese Alps. The rock- 

 garden, in sandy loam. Division. 



Serapias cordigera (Heart-shaped S.) 

 A curious Orchid, 1 ft. high. 

 Flowers, in summer; large, brownish- 

 red, 4 or 5 in a loose spike ; lip large, 

 red, nearly heart-shaped, hairy, fur- 

 nished with two prominences at the 

 base; bracts exceeding the flower 

 in length ; sepals, oval, pointed. 

 Leaves, oblong - lanceolate, gradually 

 diminishing into bracts. &. Lingua is 

 distinguished by having bracts only as 

 long as the flowers, and only one 

 prominence at the base of the lip. 

 Damp meadows and forests in the 



South and South-west of France. 



On the sunny slopes of the rock-gar- 

 den or in the select border, in deep 

 and good moist soil. Separation of 

 the root-knobs. 



Seseli gummiferum (Gem Seseli). 

 A handsome silvery plant, 18 in. to 3 ft. 

 high. Flowers, in summer ; rose- 

 coloured, in terminal, convex, many- 

 rayed umbels ; involucrum few-leaved. 

 Leaves, thrice pinnate, glaucous, with 

 wedge-shaped, trifid segments ; stems 



covered with fine down. Crimea. 



Warm banks and sunny slopes and 

 nooks on the southern side of the 



rock-garden, in dry well- drained soil. 

 This frequently perishes in winter on 

 cold clay soils and on such should be 

 planted on banks. It is probably a 

 biennial and more likely to be, useful 

 in the subtropical garden, for which 

 purpose it should be annually raised 

 from seed,, to be sown as soon as 

 ripe. 



Sida incarnata (Pink-flowered Sida). 

 A showy perennial, from 1 4 to 2 ft. 

 high. Flowers, in summer ; very 

 showy, pink, nearly 1| in. across, in 

 a close pyramidal spike. Leaves, 

 smooth, long-stalked, deeply cut or 

 lobed with very fine short hairs on 

 the edges; lobes from 5 to 7, variously 



toothed or lobed. Brazil. Borders 



and naturalization, in warm sandy 

 loam. Division or seed. 



Sidalcea malvaeflora (Mallow-flowered 

 8.) A vigorous perennial with a 

 branching stem nearly 3 ft. high. 

 Flowers, in summer ; very handsome, 

 pale rose, about 1 in. across, in clus- 

 ters on the tops of the erect branches. 

 Leaves, stalked, deeply divided, the 

 segments again divided or lobed ; 

 stem and branches of a light green 

 colour with a few scattered short 

 white hairs. Oregon and New Mexico. 



Borders, in any soil. Division 



and seed. 



Sideritis syriaca (Syrian Ironwort). 

 A dwarf herb densely clothed with 

 white wool, with short woody stems 

 6 to 15 in. high. Flowers, in summer; 

 yellow, 6 to 10 in a whorl; corolla 

 clothed with silky down outside, twice 

 the length of the calyx. Leaves, thick, 

 lance-shaped, narrowed at the base ; 

 lower oues stalked, unequally toothed; 

 floral ones stalkless, entire, heart- 

 shaped at the base, equalling the 



calyces. Candia and Palestine. 



Warm borders, or in the drier and 

 rougher parts of the rock-garden, in 

 light sandy soil. In warm sandy 

 loams this would probably form a
