PERUVIAN REGIONS.

The Cinclwnas and abundant epidendric Orchidacece, mentioned and 

 described in the Flora Peruviana, probably occur yet lower down ; 

 perhaps, in an additional mountain-region. 



7. The Interior Forest-region of Equatorial America. 



The " montaiios" were described as fairly down at the base of the 

 Andes ; being, in fact, the commencement of the profuse rains and 

 great Equatorial forest. From the Flora Peruviana, we learn, that 

 the BerthoUeiia makes its appearance in this moist and warm climate ; 

 together with Heliconias, Aracece, many singular Palms, and the tribes 

 of plants generally that we are accustomed to associate with Tropical 

 America : the species, however, notwithstanding that the forest is con- 

 tinuous, seem universally distinct from those growing on the Lower 

 Amazon, and along the Atlantic coast. 



It thus appears, that in proceeding inland three hundred miles from 

 the Pacific, we traverse at least six botanical regions ; so distinct in 

 climate, that the plants growing generally in any one of these regions 

 will not flourish in either of the remaining five. 



On the 24th of May, after leaving the alpine region, our party con- 

 tinued down the Paramera by the Canta Valley ; and stopped for the 

 night at the first house, situated about a league above Culuay. 



On the 25th, we continued leisurely down the Canta Valley, collect- 

 ing on our way ; leaving the Paramera, and towards evening arriving 

 at Obrajillo, where we stopped for the night. 



On the 2Gth, we continued down the Valley, collecting by the way ; 

 leaving the mountain-region, and towards sunset stopping for the night 

 at Yaso. 



On the 27th, we set out at 7 a.m., continuing down the Valley ; 

 passing Yanga at 2 p.m., we proceeded to a house a short distance 

 below, and stopped there for the night. 



On the 28th, we crossed the mountain-ridge to Caballeros; and con- 

 tinued on until late in the evening, when we entered the city of 

 Lima. 



On the 20th of June, news came of the arrival of the Vincennes. 

 The vessels of the squadron, the missing schooner Sea-gull excepted, 

 were now all at anchor before Callao.
