DESCRIBED BY LINNJEUS AS CL. ELUTERIA AND CL. CASCABILLA. 27 
clear up much of the obscurity in which the species furnishing 
the Cascarilla-barks of commerce have been involved. I willingly 
leave in his own able hands that portion of the subject which 
-relates to the Materia Medica and the commercial history of the 
Barks in question, and shall limit myself, in the present brief 
notice, to the botanical history and discrimination of the species 
which have been confounded together under the specific names of 
Eluteria and Cascarilla. 
The first account given by Linneus of C. Eluteria occurs in 
* Hortus Cliffortianus' (1737), pp.486-7. Ofthe plant there care- 
fully described, an authentic specimen exists in Cliffort’s Herbarium 
in the British Museum, with a portion of the description attached 
in Linnsus's own hand, and marked with the only synonym 
quoted :—“ Cortex Ilatheria. Elutheria Provid. folio cordato subtus 
argenteo. Sweet bark, s. cortex bene olens. Petiv. Collect. p. 4 
n.276." The synonym; the habitat, crescit in Insula Providentia ;" 
and the name Hlutheria, derived from the adjacent island of 
Eleuthera, all bespeak its Bahamian origin. Of this very distinct 
Species, а specimen brought from the Bahamas forms part of 
Catesby's collections in the British Museum ; and there also exist, 
in the Banksian Herbarium, а similar specimen of Catesby's from 
Gronovius, together with specimens from the Herbarium of Philip 
Miller, from the “Bahama Islands, Long Island," collected by 
Peter Dean, Esq., in 1788; and from the “southern parts of North 
America," collected by André Michaux, the latter sent under the 
erroneous name of Croton Cascarilla. Linneus himself never 
possessed a specimen; and having, apparently, entirely forgotten its 
characters, he referred to it in his ‘ Flora Zeylanica' (1748), No. 
366 (with several other equally erroneous synonyms), the Ma- 
hapatigaha of Hermann's ‘Museum Zeylanicum, of which no 
specimen existed in Hermann’s collections, and added the officinal 
synonym of Cascarilla. Of the additional synonyms, that quoted 
from Breynius, Plukenet, and Seba, unquestionably belongs to the 
plant subsequently named by Jacquin Croton niveum; and that of 
Plumier and Catesby, as we shall hereafter see, is the foundation 
of Linneus’s own Clutia Cascarilla. In his ‘ Materia Medica,’ 
published in the following year, he ascribes the Cascarilla Bark 
to the Eluteria of his ‘ Flora Zeylanica, with the single synonym 
of Catesby; while in the first edition of ‘Species Plantarum,’ 
published in 1753, he quotes, under Clutia Eluteria, his ‘ Flora 
Zeylanica’ and * Materia Medica,’ Eluteria of * Hortus Clifforti- 
anus, and the mistaken synonym of Plukenet and Seba. Of all
