 {Metten.). — Var. )3. Andes of Peru, Brackenridge, M'Lean. Sandwich Islands, 

 Diell, Douglas, n. 49. — Very nearly allied to A. viride, as already observed, but 

 I believe truly distinct : the stipes and rachis are more slender and flexuose, 

 the pinnae of a more delicate texture, more variable among themselves in figure, 

 with a great disposition to be 2-3-lobed, never with the margin regularly and 

 deeply crenate : and the involucres are permanent. The little bulbs throwing 

 out stoloniferous plants are very remarkable. Although Mettenius had only seen 

 the figure of Brackenridge of his J. rhomhoideum, he rightly judged it to be a 

 form of A. fragile : I have the same also from Peru {McLean), with fronds a foot 

 long and pinnrr. nearly three-quarters of an inch long, almost ternately divided 

 (so as, Mr. Brackenridge says, almost to resemble A. triphyllum, Pr., Hook, and 

 Gr.); while, from the Sandwich Islands, I possess specimens nearly a foot and a 

 half long. Probably this should be considered the normal state of the plant, and 

 the original A. fragile its lofty alpine condition. Both are equally bulbiferous.
