1916] Blake, — Limonium in North America and Mexico 63 



Quebec : Anse a Persil, Riviere du Loup, July 1913, Bro. Victoria 53.

 Stabler.

 Atlantic City, 1884, L. F. Ward. 



The commonest and most widespread of our species, and the only 

 one found on the Atlantic coast north of North Carolina, so far as 

 yet known. This beautiful species, well distinguished by its strongly 

 pilose calyx with acuminate teeth 1.5-1.7 mm. long, has passed for 

 more than a century as Statice caroliniana Walt., but the type of that 

 species belongs to a very different species with glabrous calyx (see 

 no. 1). Occasionally the hairs on one or two of the ribs are sparse, 

 but even in such extreme cases a few may generally be found reaching 

 to the middle of the tube or beyond. At least three of the ribs seem 

 to be always strongly haired, and no sign of intergradation with the 

 southern L. Nanhii has yet been seen. A puzzling specimen from 

 Virginia {Clayton 573, Brit. Mus.) has the calyx-teeth and other fea- 

 tures of L. trichogonum, but the absolutely glabrous tube of L. carol i- 

 nianum, and may be of hybrid origin.
