234 FLORA ANTAECTICA. [Fuegia, the 



long and consists of a single stem (probably one of several from the same root) bearing linear, obtuse, and entire 

 radical leaves, scarcely an inch long ; tlie ascending portion is erect and scarcely branched, with three sessile, ovato- 

 oblong leaves ; the raceme 3 inches long ; pods erect, 4 lines long and less than one in breadth, borne upon stout 

 pedicels shorter than themselves ; seeds immature, small, pale red brown. In this genus, characters taken from a 

 solitary though complete specimen are invalid, and since it is undistinguishable from some North American and 

 European states of B. incana, I am obliged to unite it with them ; for I can find no reason to suppose that they 

 will eventually prove distinct. 



It is very singular that this plant, apparently identical with one so abundant throughout the Arctic regions 

 and the elevated mountains of the north temperate zone, should not have been seen in the southern by any col- 

 lectors save Dr. Gillies, who is stated (Bot. Miscell. vol. iii. p. 138), to have found a solitary specimen on the 

 Andes of Mendoza, and Commerson. It certainly does not appear amongst the plants of the Colombian Andes that 

 have been published by Humboldt, or more recently discovered by Col. Hall and Professor Jameson. Variable as 

 the species of this genus are in the Northern Hemisphere, they are equally so in the Southern ; still, as they seem 

 to present tangible characters, I have availed myself of them here in drawing up the subjoined list of the South 

 American species known to me*. With regard to the sections proposed for these twenty species, they are tolerably

The species in the Hookerian Herbarium, received as n. 885, from M. Hartweg, is the same as Professor 

 Jameson's B. aretioides and Humboldt's figure ; but it is not the B. obovata, n. 885, of Mr. Bentham's herbarium, 

 apparently a very different species.

 obovato-spathulatis apice rotimdatis integerrimis, racemis abbreviatis folia summa paulo superautibus, sepalis late 

 oblongis dorso pubescentibus, petalis flavis, pedicellis fructiferis elongatis, siliculis latissime ovato-rotundatis acutis, 

 stylo brevi, valvis planiusculis incanis, seminibus majusculis late obovatis.
