plexis opacis scabris." Lightf. FL Scot. 894.—“ L. (scaber) fila-

At last, I cannot conclude without expressing my suspicion of 
the accuracy of some of the synonyms quoted by Dillenius for 
Species 8. p. 66. f. 8. t. xiii. v. g. Syn. St. Br. p. 65. n. 3. 
* Muscus coralloides lane nigre instar saxis adherens.” D. Ste- 
vens.—* Precedenti (L. chalybeiformi sc.) ramosior et majus ex- 
pansus, minus vero rigidus." This short comparative description, 
as: well as Dillenius’s own definition, ** Usnea Jane nigrw instar 
saxis adherens,” and his description, “ biunciali et triunciali 
nostra specimina longitudine sunt, filamentis ubique teretibus, 
magis atris et magis confertis, quoquoversus sparsis et invicem 
implexis," &c. convey a much juster idea of a full sized specimen 
of f. 32. t. xvii. than of Mr. Brewer's plant; particularly to such 
as have seen both plants in a growing state ; and seem to inti- 
mate that even the great Dillenius himself laboured under some 
degree of illusion in this instance. But f. 8. t. xiii. is a good re- 
presentation; and that part of Mr. Stevens's definition above 
quoted, * Muscus coralloides lan &c., is likewise characteristic 
of Mr. Brewers plant, which is there introduced, that is LicuEN 
bicolor.
