IN VARIOUS I'AllTS OF TIIK GLOBE. 197 



I was compelled to travel 80 leagues in order to get a pass- 

 port from tlie President of Bolivia ; this done I again visited the 

 ruins of Tiahuanaco and entered the Peruvian territory by the 

 province of Carabaya. On the 22nd of June I quitted the 

 village of Moho, through which I had before passed, and on the 

 24th I was for the fifth time on tlie crest of the Andes, which I 

 crossed by one of the most picturesque but bitterly cold passes I 

 remember to have ever met with ; on the evening of the same 

 day I was, however, once more in a delightful climate at the 

 pretty village of Sina. At Quiaca I found guides to conduct me 

 to the valley of San Juan de I'Oro. Leaving Quiaca for the 

 large forests, I passed small woods of Myrtles, JBefaria, Mela- 

 stomads, and Datura. On the evening of the 3rd day from my 

 departure I came to a curious pass which merits a short descrip- 

 tion ; it was a deep gallery, hollowed in the top of a steep and 

 very rugged mountain : the continual moisture had so softened 

 the soil that to move along was extremely difficult — so much so 

 that I at one time thought I should remain for ever in the mud. 

 The vegetation was peculiar ; the whole ravine was covered with 

 a thick carpet of Sphaf/num, upon Avhich a Genlisea balanced 

 its large lilac flowers in the midst of Droseras ; Lycopods and 

 Ferns of every shape were there, with Orchids, Melastomads, and 

 Heathworts. 



From San Juan de I'Oro I was compelled to go to a place 

 called Tambopata to find a guide, which I succeeded in doing. 

 He was an intelligent Cascarillero, and we established ourselves 

 on a little promontory at the confluence of two rivers, from whence 

 we made daily excursions into the neighbouring country. I 

 found 15 species of trees to which my especial attention was 

 directed, but my small stock of paper compelled me to leave 

 behind many plants I should have liked to have brought away. 

 One of the most remarkable trees in these forests was a Stellate, 

 afterwards named Gomphosia chlorantha ; it forms on the top 

 of the mountains large woods, sometimes alone, sometimes in 

 company with a large Hedyosmam, called Chilca, and the 

 curious tree I afterwards named Elceagia Maricp, which recalls 

 the common name of Aceite-Maria by which it is known in the 

 province of Carabaya! The Triplaris, facetiously called by the 

 Bolivians Palo Santo, is very common in the low parts of the 

 forests, where its red tops contrast strangely with the brilliant 

 green by which they are surrounded. 



Departing from Tambopata and the Villa San Juan de I'Oro,* 



* Not a trace either of this town or of San Gaban, the ancient capital of 

 the department of Puno, is to be found, though both are laid down in the 

 most recent maps.
