This is one of the many interesting discoveries made by Pro-v
fessor Schmidt in the Canary Isles, whence he returned in the
year 1815, to embark in the ill-fated expedition to explore the
sources of the Zaire. He made the request that I would give his
cryptogamie plants to the public in some shape or other.
