Baths of Collina, Macrae.—In M. setosus the fruit is fur- - 
nished with a strong rib, running down from the centreof 
each calycine segment, which, moreover, is provided with 
two or three processes or teeth; the lower being patent 
and blunt, the upper one erect and sharp, as is usually 
noticed in the generic character. In the present species 
these ribs and teeth are replaced by membranaceous 
wings, oneof which, however, is frequently abortive. The 
cotyledons are large, flat, and foliaceous; the radicle 
straight and superior, nearly half aslong asthe cotyledons. 
(1.) Aceena splendens, (Hook. et Arn.) ; tota sericeo- 
lanata, floribus 3-4-andris in spicam laxam elongatam 
dispositis, fructibus magnis ovoideis tomentosis, aculeis 
elongatis glochidiatis numerosis, caule erectiusculo, 
- foliis ad basin caulis confertis sub-3-jugis, foliolis ellip- 
tico-oblongis apice dentatis.— Cordillera of Chili, Cum- 
ing (N. 299); Bridges, 1832, (N. 3.) who finds it also 
at Sierra Bella Vista, Aconcugua.— The leaves are 
covered on both sides with beautiful long silky shining 
hairs, which are close-pressed: those on the stem are 
more patent and woolly. Between the leaves and the 
spike occurs sometimes one, or at most two, distant 
minute trifid leaves or bracteas. ; 
(2.) Acsena integerrima, (Gill. mst.); tota sericeo-la- 
nata, floribus in capitulum globosum dispositis unico 
alterove distante, ovario aculeis brevibus glochidiatis, 
caule caespitoso prostrato, foliis sub-radicalibus confertis 
4-jugis, foliolis ovato-oblongis integerrimis vel apice 2- 
3-dentatis, unico. caulino plus duplo minore.—Near 
El Arroyo de los Portreros, Andes of Mendoza, Dr. 
Gillies.—'Dhis seems to differ from the last species in 
its smaller size, and, according to Dr. Gillies, in its pros- 
trate stems. The specimens are only in flower, but 
-these flowers are much smaller than in A. splendens, and
