HooKER, Coll, p. 118, mentions a specimen in the collection of Lyall which 
is recorded for »Wellington Channel?*, but lie adds in a note »more probably from 
Disco», which may be the right conjecture.

While, as I have pointed out in my Flora Ellesm., p. 133, the main form of 
this species is mostly restricted to alpine locahties in the southern parts of its range, 
It appears in the Arctic Regions generally as var. confusa, (Lindeb.) Kjellm. Both 
forms, however, are connected by a series of intermediate ones and thus become 
impossible to keep up as separate species. The var. confu.9a also may show a 
considerable hkeness to L. campestris and L. multiflora^ which accounts for several 
wrong records. Taylor, 1. c., p. 331, for instance has both in his list and besides 
L. hpperborea, R. Br., also. This ought to indicate that the latter name was meant 
for L. mvahs, (Laest.) Beurl., but I have not seeii any specimen to prove that 
Taylor has actually found the lastmentioned species. The name of Brown includes 
both L mvahs and the var. confusa of the present species, and several låter authors 
have also, intentionally, as for instance Ambronn, 1. c, p. 88, or unawares thrown 
them together, so as to make their records of doubtful use. Among these I mav 
mention Rae, Exp., p. 214, who records it from the Melville Peninsula, and J. D. 
Hooker, who has it in the lists of Walker's and Lyall's plants. I have not found 
the specimens on which the records from North Devon are based, but most probablv 
they might be transferred to this species as the most common of the two as I 
have done above with Tabr's specimen from Big Island. In that case the locahties:
