394 MR. F. N. WILLIAMS: REVISION 
This very distinct and remarkable species is limited in Europe 
to the range of the Sierra Nevada, and forms broad hemispherical 
bristly tufts from 50 to 20 centim. high, growing on the alpine 
slopes and also above the snow-line at 1750 to 2700 metres. As 
J. Gay points out, in plants raised from seed in the Paris Botanic 
Garden, the whole plant is glaucous, and not as one sees it in 
Boissier’s otherwise well-coloured plate. It was only a consider- 
able time afterwards that glabrous specimens referable to this 
species were found in S. Marocco, by Mr. E. Cosson and Mr. 
John Ball. In all the specimens I examined the seeds appeared 
to be quite smooth, and free from elevated tubercles, neither had 
they the rough surface mentioned in Willkomm's description. 
This was also certainly the case in the Marocco specimens.
