61, 1880.) Plants very robust, resembling in habit a robust S. Gir- 
gensohnii. Tufts pale and lax. Stem-leaves very large, otherwise 
normal. Pores in the stem-cortex very strongly developed. Fascicles, 
according to the wetter or drier habitat, more widely separated, or 
nearer together; the spreading branches even immediately below 
the capitulum very long (to 3 em.) and recurved ; cortical cells of 
branches with scattered pores; branch-leaves very large, imbricate 
or with the apex more or less squarrose. Of this variety the var. 
flagellaceum Schlieph. (in Irmischia, 1882) (syn. var. flagelliforme

Stem-cortex of 8-4, rarely 2-3 layers; sapertcial cells with 1,
