Four to six inches long. Lower part of the stem naked and much 

 branched. Leaves subsecund and subttiJcate, as observed by Wah- 

 lenberg, their points callous. Flowers large, pure white. Smitli 

 says the stt/les are sometimes 4 and 5, and my capsules have de- 

 cidedly 1 teeth, so that I have no doubt but future observations upon 

 fresh specimens v\all induce us to renioveitto the genus Cerastiurn, 

 and tlie MS. name of Mr. G. Don may very well be retained to it. 

 It is common in Iceland, Lapland, and Norway. 



S. S. scapigera {ma???j'Stalked Stiic/iivort), stem shorter than 

 the flowerstalks, leaves lincar-laiiceolate crowded pubescenti- 

 scabrous at the margin, cal. 3-nerved as long as the petals.

i possess only cultivated specimens of this remarkable plant, which 

 was first described by Willdenow. He attributes to it single-flower- 

 ed pa/2<Hc/es, but in my plants these peduncles, of which many arise 

 from the extremity of the very short stems, are mostly branched 

 in the middle, where tliey h.ave 2 smaliovate acute membranaceous 

 bracteas.
