and Miscellaneous Particulars. 
2354. Alectoria, seems to derive its name from otXixroo^, unmarried, because nothing has been made out 
respecting the male flowers. A. usneoides is a species which grow on trees in warm countries, such as Asia, 
Africa, and America, hanging down in branches from six to eighteen inches long : it was used by the Arabian 
physicians as a cordial, and also for the purpose of procuring sleep. A. juoata occasionally supplies the rein- 
deer with food ; for which purpose the Laplanders cut down the trees, that the Lichen may be devoured from 
the topmost branches. 
2355. Ramalina. This name does not appear to have any obvious meaning. The species are little bushy 
tufts generally covered with soredia. They are found in all parts of the world upon trees and rocks ; but 
chiefly upon the former. 
2356. Comicularia. So called in allusion to the multitude of little horn-like divisions into which the thallus 
is divided. Crustaceous branched tufts, with a solid axis.
