trate and rooting) stems, with the less describable dif- 
ferences of colour and susceptibility to frost, that I did not 
hesitate to retain L. Azorica as a distinct species in my 
formerly published * Catalogue? Since that time I have 
received a root from St. Michael's, accidentally in the soil - 
with other.living plants, kindly sent to me by Mr. Hunt; 
and as this example from St. Michael's, as well as other 
dried specimens from the same island, stand between my 
former examples of L. Azorica and the English L. nemorum, 
both in the form of the calyx, and in their long, trailing, 
and occasionally rooting stems, I find it impossible now to 
indite any written character which will distinguish L. Azorica 
from L. nemorum. . Nevertheless, the eye can do so by slight 
peculiarities of colour and form; and a frosty night shows 
most convincingly that some decimo of constitutional B 
susceptibility exists between the English species and its 
Azoric representatives, though the leaves of the latter will 
bear some few degrees of frost.
