A widely diffused, and difficult genus, of which about half the best 
distinguished forms occur within our limits. &. scopwlorum (Retz) Ach., 
found on maritime rocks throughout Europe, and extending to Iceland 
(Th. Fr. Lich. Arct.) is however unknown to me as North American; 
though reckoned as such by Nylander. But some of the most remarkable 
species are peculiar to this continent. A. reticulata (Noehd.) Krempelh. 
(R. Menziesii, Tayl. R&R. retiformis, Menz. hb. Tuckerm. Syn. N. E.) is 
confined to the coasts of California and Oregon, reaching northwards as 
far as Vancouver’s Island.——R. Menziesii, Tuckerm. Syn. N. E. (2. lepto- 
carpha, Tuck., Suppl. 1858) is another, large and pendulous Californian 
species, also discovered by Menzies, which has added a very unexpected 
character to Ramalina ; the young fronds being, as it certainly appears, 
puberulent! Fronds now sparingly foraminous; and at length sorediifer- 
ous. The species is closely akin to R. reticulata.— R. levigata, Fr. 8. 
O. V. (Tuck. in Bot. Wilkes exp. R. Eckloni, &c., Auctt.) a very wide- 
spread lichen throughout the warmer regions of the earth, and often 
approaching though pretty readily distinguishable from &. calicaris, has 
occurred here in Louisiana, Texas and New Mexico.— R. tenuis, Tuck. 
Suppl., another southern Ramalina, with the same range as the last, 
must be distinguished, by the spores, into two, otherwise most nearly 
related forms, which now grow intertangled together, and can scarcely be 
discriminated but by the microscope. One of these forms, with small, 
ellipsoid spores, evidently approaches R. rigida, Ach. The spores of the 
other are fusiform, and at length much elongated, reaching even 0,030-32™™ 
in length. A nearly terete, torulose, Usnea-like Ramalina, with con- 
spicuous apothecia, and ellipsoid spores, has occurred lately so far north 
as the Pines of New Jersey (Mr. Austin) and belongs without doubt to
