I hope the figure now given, and which is a faithfulrepresentation of the growing plant, will show that we have somegrounds for our opinion. Cladop/wra Brownii appears to be peculiar to the BritishIslands, and, so far as I know, has only been found in thestations above given. At Wicklow, I observed it first in 1833 ;and in 1842, when I next visited the station, the plant was stillto be found, though not in so luxuriant a state, probably fromsome failure in the supply of moisture.
