 another tree variety with a somewhat darker leaf, wliioli Br. 

 Weddell classed as a distinct species, and called C. BoUviana 

 in 1849, but which he now considers to be a mere variety of 

 C. Calisaya. The other good kinds in the forests of Boli\aa 

 and Caravaya are C. micrantha, and two varieties of C. 

 ovata. 



Dr. Weddell brought seeds of C. Calisaya to Paris, which 

 were raised in the Jardin des Plantes in 1848, and others in 

 the garden of the Horticultural Society in London, where one 

 of the plants flowered.^ Many of these plants were given 

 away, and some of them were sent by the Dutch Government 

 to Java. 



Plants of C. Calisaya are now flourishing in India. The 

 yield of quinine for the best kinds of calisaya bark is 3*8 

 per cent., that for the Josephiana variety 3*29.^

 bark ; and in 1859 the quantity and value exported were : —
