IONIDIUM. 



gathered among rocks at Lactacunga in Quito. This latter species 

 has the leaves all opposite, and the pedicels much longer than the leaves, 

 in both which circumstances it differs from I. parviflorum. 



Along with this Cuchunchully Mr. Strangways received another 

 sample called Cuchunchully Colorado, which consisted of a very small 

 quantity of the first, mixed with some Cinchonaceous plant, not in 

 flower, but very like Mitchella repens, and forming the principal part of 

 the parcel. Independently of their Botanical distinctions the infusions 

 of these plants were extremely different; that of the first being a pale 

 bright amber colour, of the latter a cloudy dull green. Samples of both 

 these are deposited in the Materia Medica Museums of University 

 College and King's College London, and were sent to the Medico- 

 Botanical Society. 



These Ionidia deserve to be attentively studied with reference to 

 their medicinal properties. In addition to the foregoing the following 

 have been mentioned as furnishing active principles.
