inferiore abortivo, superiore stylo longo persistente ter- 
minato.—At Magote Aspera, on the sides of mountains 
near Mendoza, Dr. Gillies.—' The leaflets of this curious 
plant are larger than any other of this division. 
(17.) A. pedicellata (Hook. et Arn.); fruticosa, pubescens, 
spinis paucis ramosis gracilibus, foliis sparsis sub 7-jugis, 
foliolis obovatis subretusis integerrimis, racemo terminali 
laxo, pedicellis calyce 4-plo longioribus, dentibus caly- 
cinis acuminatis, leguminibus sub 6-articulatis sinu. 
angusto dense longissime plumoso-setosis.— Coquimbo, 
Cuming (N. 911.)—This approaches in habit most to the 
last, but differs widely by many important characters. 
(18.) A. trijuga (Gill. mst.) ; fruticosa, pubescens vel 
glabra, spinis gracilibus dichotomis, folis sub-3-jugis, 
foliolis parvulis late obovatis retusis, racemis elongatis ter- 
minalibus simplicibus, dentibus calycinis brevibus acutis, 
leguminibus linearibus 3-5-articulatis falcatis dense lon- 
gissime plumoso-setosis.—A. Hookeriana; A. Arnot- 
tiana et A. Doniana. Gill. mst.—g. robustior ; foliolis 
majoribus nonnunquam submucronatis.—A. argentea ; 
A. alpina; et A. Lambertiana, Gill mst.—a. and g.; 
Andes of Mendoza, Dr. Gillies.—nom. vernac. Cuerna 
de Cabra.—TVhis is very spinous and hence called * Goats’ 
horns” by the natives. It is more or less robust, and the 
leaflets are variable in size and pubescence. The fruit is 
alike in all the states, which we have reduced as above. 
(19.) A. horrida (Gill. mst.); fruticosa, subczespitosa, 
ramis distortis validis, spinis robustis brevibus divaricato- 
ramosis horridis, foliis 3-jugis, foliolis parvulis linearibus 
 canaliculatis, racemis perbrevibus subumbellatis, denti- 
bus calycinis brevibus acutis, leguminibus 3-4-articulatis 
longe plumoso-setosis.—a. A. Capricornica, Gill. mst.— 
Mountains near Mendoza, Dr. Gillies.—g.; minor; ramis 
brevissimis dense czespitosis, foliolis latioribus.—A. cæs- - 
pitosa, Gill. mst.—Los Manantiales near El Portillo, 
Andes of Mendoza, Dr. Gillies.—This is unquestionably 
nearly allied to the preceding, but appears to be a much 
stouter plant, with more tortuous branches and shorter
