246 NOTES OF A BOTANIST CHAP. 



Hieracium, a very pretty Leria with large blue 

 flowers, growing on shady banks, and a branched 

 Composita with silky-white leaves and handsome 

 purple flowers, besides several Solaneae, Labiatae, 

 Ehretiacese, and two Acanthacese, which last order 

 seems entirely absent from the cold region ; also 

 a suffruticose Lantana with yellow flowers, which 

 I had not seen elsewhere. In moist places a little 

 Cuphea was very abundant. The shrubberies con- 

 sisted chiefly of Composite, whereof one resembled 

 a Spiraea in aspect and in the odour of its numerous 

 small white flowers ; but there was also a new 

 Biittneria, and the common Clematis of the warmer 

 parts of the Cordillera climbed about everywhere. 



In cultivated ground, especially in the maize and 

 cane fields, two delicate broad -leaved Paspala 

 called Achi'n spring up in great abundance. 

 Every day I saw the servants of the farm get 

 bundles of them for the cows, pigs, etc., which ate 

 them with greater avidity than even the alfalfa, so 

 that, though weeds, they were nearly as valuable 

 to the owner as the crops amongst which they 

 grew. 



Among the trees, which grew chiefly along the 

 banks of the river, were two species of Lycium not 

 previously seen, an Inga, a Mimosa, and a Bigno- 

 niacea with broad opposite leaves and cymes of 

 large purple flowers. The last, known by the name 

 of Hualla, is frequent in the Western Cordillera 

 at from 6000 to 9000 feet, and is one of the best 

 timber trees. It is not improbably the little-known 

 Dclostoma integrifolinvi, Don ; but it is not a Delo- 

 stoma, for, besides an essential difference in the 

 calyx, the septum is contrary to the valves, as in
