8 TIEPORT OF M. GUILLEMIN. 



far-famed trees. Anxious to establish a point of such medi- 

 cinal and commercial importance, I have deposited in the 

 Museum of Natural History in Paris, flowering specimens of 

 the Cinchona, found by M. Riedel and others, collected from 

 a tree which is known under the very incorrect name of ]lio 

 Quinine, but which belongs to a genus quite distinct from the 

 Cinchonas. To close the enumeration of my discoveries, I shall 

 content myself with adding, that I detected, growing not 

 unfrequently in the environs of Rio, the Ilex Paraguaijensis 

 of M. Auguste de St Hilaire, perfectly identical with the 

 tree which the Jesuits planted in the Missions of Paraguay, 

 and whose foliage is an article of great importance through- 

 out Spanish America, and vended under the name of Para- 

 guay Tea. A living plant of this shrub was brought home 

 by me, and placed in the Royal Garden at Paris, as well as 

 a species of Vanilla, and many other rare and interesting 

 plants. I also made a valuable collection of woods employed 

 for dyeing, building, and cabinet-work, with samples of their 

 flowers, fruit, and leaves, to facilitate botanical determination. 



Early in January, 1839, M. Houlet began anew sowing 

 Tea, not only in the open ground in our little garden, but 

 also in pans, in order to facilitate the lifting of the young 

 plants, and putting them into the cases that I had brought 

 for the purpose. The heat being excessive, we purchased 

 mats, that we might shelter them from the sun, and we gave 

 them water far more frequently. Many of the seeds that we 

 had sown a month previously were already appearing above 

 ground, but the soil being of too compact a nature, some did 

 not come up, which warned us to make choice in future of a 

 lighter kind of soil. 



The period now arrived when I was to visit the Tea plan- 

 tations in the province of St Paul; and hoping that the 

 cultivators would give me some of the young shrubs, I took 

 M. Houlet with me. leaving the charge of our collections and 

 seedlings to a M. Pissis, a French geologist and engineer, 

 with whom I iiad formed an intimate acquaintance, and who 

 most ol)]igi:igly offt-red to attend to them during niv absence.
