which are erect (not drooping) in bud, and by its whitish (not bright 

 yellow) flowers. The leaves are more conspicuously acute than in 

 any other species of the section, and end in a httle, thorn-like point. 

 In the pecuhar greenish-white tint of the flowers it matches S. ano- 

 petalum, as also in its acute leaves and inflorescence erect in bud ; but 

 the latter has leaves and flower stems of only half the length, the 

 leaves are linear and terete, and the inflorescence flat,- not sub- 

 globular, in bud. 



The plant varies much in size and colour, from robust forms with 

 flower stems two feet high bearing leaves up to i^ inch long, to

 pale green or dark green to fine purple-glaucous. The large forms 

 include var. latifolium of Rouy and Camus, "Flore de France," 

 7, 108, which is also the S. nicaeense of Allioni, " Flor. Pedemont."
