natifida, wider which species it is mentioned as var. y, m our 
first volume. If we take ordinary specimens of L. pinnatifida and 
compare them with specimens of our present plant, they appear 
distinct enough ; but narrow and ill-grown individuals of the 
former species come very close, it must be confessed, to the latter. 
The chief characters of our LZ. cespitosa are a cylindrical frond, 
with alternate and very erect ramuli. The latter characters and 
the very lurid colour distinguish it from Z. obtusa. 
L. cespitosa appears to have been first taken up as a species 
by Lamouroux, but was long neglected, or confounded with 
L. dasyphylla. The credit of restoring it to a place in the system 
is due to M. Montagne, who has given an excellent account 
of it in Mr. Webb’s Nat. Hist. of the Canary Islands. It has 
a wide geographical range, and is tolerably abundant in the places 
where it occurs.
