IN THE CINCHONA FORESTS 283 



I have no doubt, from their resinous juice, belong to the same 

 order. 



MeUacea, i. A species of Trichilia. called Muruvillo, whose 

 bark is held as a febrifuge, barely enters the Bark region at San 

 Antonio, but does not extend up to it at Limon. A tallish tree, 

 with pinnate leaves and very large serrated leaflets, which was 

 putting forth large terminal panicles when I left the woods, 

 probably belongs to this order. 



Zygophyllea, i. A fine tree of 40 feet, with large opposite 

 pinnate leaves ; it is closely allied to Guaiacum, though scarcely 

 referable to that genus. 



Podostemacea. The withered remains of at least three species 

 were observed on granite rocks in the river San Antonio, and 

 they are the first of the family I have seen in the Andes. 



Oxalidacece. At San Antonio grow two species of Oxalis, 

 both of which I have previously gathered, the one on the eastern 

 side of the Andes near Bahos, and the other at Pallatanga on 

 the western side. 



Caryophyllacea. A solitary species of each of the genera 

 Stellaria and Drymaria grows very sparingly. In ascending 

 the eastern side of the Andes, I first came on a Stellaria at 

 between 2000 and 3000 feet. This order, frequent enough in 

 the upper regions of the Andes, seems to exist in the plains at 

 their base only in the genera Polycarprea, Drymaria, and Mollugo, 

 all three very scarce on the Atlantic side, but the last-named very 

 abundant on the Pacific side. 



Portulacea. A Portulaca grows in sandy places inundated by 

 the Rio San Antonio. 



Polygonetz. A Triplaris, apparently identical with that observe d 

 at Puma-cocha, and possibly distinct from T. Sim'/ninn'tinis, 

 extends a little way into the territory of the Red Bark, and in 

 descending from thence becomes more abundant all the wa\ 

 down to the plain, where it is called by the Guayaiiuilians Arl><>l 

 de frios or Ague tree. Its presence, indeed, is a pretty sure 

 indication of a humid site. 



Amarantacea, i. A woody twiner. There are U -sides two or 

 three weedy plants of this order, probably species of Telantlu T.I. 



Chenopodea. Two common weeds ; one of them being the 

 ubiquitous Chenopodium aml>>-osiiilcs, which grows with almost 

 equal luxuriance in the elevated'central valley of the Ande- and 

 in the plains of the Amazon and Guayaquil. 



/'ipi'mcete, 5. Species of this order are very numerous. I sa\v 

 perhaps as many as twenty, belonging chiefly to the genera 

 Artanthe and Peperomia. A very line pepper, resembling Artnntlic 

 cximia, Miq., but a still handsomer plant, grows towards the lowei 

 limit of the Bark region. The stem is 20 ilet high, slender and 

 perfectly straight, and beset with short, distant, nearly hori/ontal
