and 2 or 3 forked branches bearing sessile flowers. Buds lanceolate, acute. 

 Flowers yellow, star-like, f inch across. Sepals yellowish, narrowly lanceolate, 

 blunt, ascending, standing up between the petals. Petals bright yellow, narrowly 

 lanceolate, very acute, patent, twice the sepals. Stamens f the petals, filaments 

 bright yellow, anthers reddish. Scales small, pale yellow, broadest above, about 

 as long as broad. Carpels yellow, slightly spreading, slender, tapering into the 

 very slender styles, equalling the stamens. 



Flowers May (gentle heat); July (cold frame). Nearly hardy 

 at Dublin. Hardy at Rostrevor. 



Habitat. — Japan, China, ? Luchu Archipelago. 



Var. robustum * var. nov. (fig. 132). 



Plant grey-green, not bright green as in type, stouter and more 

 branched, specially above. Inflorescence more leafy and often irregular 

 in form. Flowers paler, sepals longer and broader, petals broader, 

 carpels more divergent. 



A curious form obtained at the Botanic Garden at Hamburg. 

 Its greyish colour and stouter, more branched growth, give it a very 

 distinct appearance, but no difference which could be called specific 

 in the ordinary sense is to be found in the flowers. My plant sends 

 up occasionally a variegated shoot. 



f. variegatum. 



Synonym. — 5. sarmentosum variegatum and S. carneum variegatum of gardens. 

 Illustration. — Henderson's '< Illustrated Bouquet," 3, pi. 60. 



Leaves with a marginal stripe of white or cream, stems very pink. 

 This is a rather stout form of the species, approaching in this respect 

 var. robustum described above. 



5. lineare appears to be a variable plant, as Miquel describes [loc. 

 cit.) several varieties, differing from the type in stature and habit. 



The specific name refers to the narrow leaves, which were originally 

 described by Thunberg (perhaps from dried specimens) as " tereti- 

 linearia."

 (Not S. sarmentosum Bunge, for which see p. 226). 



A floriferous and showy species with a wealth of golden-yellow 

 flowers. Easily recognized at any period of growth by its light -green 

 shining tint, and its nearly terete linear leaves which, even on the same 

 plant, are arranged singly and in whorls of 3, 4, or 5.
