Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1851 edition. Excerpt: ...state no septa are visible externally, the frond being filiform. In this VOL. III. N condition it is sometimes a little difficult to distinguish specimens of Chorda lomentaria, from narrow ones of Asperococcus echinatus, except by their more chestnut colour and more polished surface, and Capt. Carmichael has described such individuals under the name of A. castaneus.
