Cartsaya javanica, Howard, Quinology of the East Indian Plantations, t. viii. 
The very interesting plant here figured, is the true 
famous ‘ Calisaya’ fever-bark, of which a remarkable variety 
(Josephiana) is represented in Plate 6052 of this work. It 
very closely agrees with the original specimens of C. Calisaya 
collected by the author of the species, the late eminent 
botanist and traveller Dr. Weddell, in the province of Cara- 
baya in Peru. Like its congeners, this species varies very 
much in the size, shape, and texture of the leaves. Mr. 
Howard identifies this form with that called ‘Schuhkraft’s 
Calisaya,’ figured in his ‘ Quinology,’ Plate VIII. The seeds 
were received by Mr. Howard from India, where thousands 
of acres are under cultivation with this invaluable plant. 
The @. Calisaya yields the most important bark for medicinal 
purposes of all the species—that known as the yellow bark ; 
and it is also that the obtaining of which for cultivation in 
India, was the principal object of Mr. Markham’s famous 
journey to the border-land of Bolivia and Peru in 1860. 
From the Eastern slope of the Andes in that region, Mr. 
Markham, assisted by his gardener, Mr. Weir, brought 450 
living plants of Cinchona, chiefly belonging to this species, to 
the Pacific coast, and thence to England, and the survivors 
to India; where, however, owing to many delays attending 
the transport, but few arrived in a living state. The diffi-
