produced at their tips. On placing together a number of speci- 
mens from Spain, Italy, Madeira, Canaries, and Azores, they 
appear entirely to connect the extreme acutum, through Virgila 
and productum, with our English Adiantum nigrum ; it being 
impossible to find any decided line or place of severance. Even 
the figure of the Irish acutum, in Newman’s History, has not 
quite the extreme of fineness or slenderness in subdivision of the 
frond; a Spanish example, brought from Castille by Mr. John 
Ball, being even more finely divided.

Ambiguity. Three examples of Botrychium, all irregular in form, 
were found by Mr. Cruickshank, on the sands of Barry, near 
Dundee, in 1839; a locality where the Lunaria is said to be 
frequent. These were referred by Mr. Newman with confidence 
to rutaceum. Three species of Botrychiwm have been recorded 
heretofore as British ; appearing in Gray’s Arrangement under the 
names of lunatum, rutaceum, and matricarioides. The first of 
these three intended Lunaria. Ray had put together the two last, 
apparently as a second species, found in Westmoreland. Pro- 
bability leans to the side of B. rutacewm being actually a British 
fern, but confirmation is needed.
