Specimens of this curious species of Chuquiraga formed part 

 of a small but interesting collection of dried plants made in 

 Caracas by Mr. Fanning, and which is now in the possession of 

 Mr. Lambert. Mr. Fanning discovered it in the vicinity of 

 Caracas, extending its feeble branches, like a bramble, for sup- 

 port over the other shrubs and trees in its neighbourhood, and 

 frequently spreading to fifteen or even to thirty feet. Mr. Fan- 

 ning has also brought to this country a valuable collection of 

 seeds and living plants, among which is the famous Cow-tree, 

 Palo de Vaca. 



This section, which has entirely the habit of Barnadesia, con- 

 stitutes a very remarkable osculant group connecimgChuquiraga 

 with that genus. The species are evidently intimately allied, and 

 although I have not ventured to separate them entirely from Chu- 

 quiraga, yet I am satisfied that they are sufficiently characteristic 

 to merit being regarded as a distinct genus.
