involucri campanulati foliolis acutis glandulosis basi calycu- 



latis, ligulis . ^ . . ? — Andes of Mendoza ; Br Gillies Base of 



the plant quite woody ; the flowering branches, except at the 

 base, herbaceous and pubescenti-glandular. Our specimens 

 are not very perfect ; but we know of nothing which will ac- 

 cord with it.

p. 57. DC. Prodr. vi. p. 416 Valparaiso, to the Andes of 



Chili; Bridges; Cumijig, [n. 65); J)r Gillies Readily distin- 

 guished from all in this section, by its comparatively small, 

 narrow, cylindrical involucres, its very compound corymbs of 

 copious capitula, and from the following of the section; more- 

 over, by the plane (not thick or fleshy) and one-nerved leaves. 



2023. (17.) S. Uspallatensis, (H. & A.) ; fruticosus glaber, 

 ramis numerosis brevibus usque ad apicem foliosis, foliis 

 coriaceo-carnosis canaliculatis bipinnatifidis rachide lobisque 

 linearibus acutis brevibus simplicibus vel divisis, corymbis in 

 ramis brevibus terminalibus oligocephalis, involucri glabri 

 cylindracei foliolis acutis non sphacelatis, ligulis sub-10 brevis- 

 simis — Uspallata, Andes of Mendoza ; Mr Cruikshanks, — /?. 



tenuior ; foliis ramisque tenuioribus Andes of Mendoza; 



Dr Gillies. — y. retrqflexus ; foliis bipinnatifidis lobis recurva- 

 tis. — Frequent on Pax-amillo, Andes of Mendoza, where it is 

 called Pachochomo, and where an infusion is drunk by the 

 miners instead of Mate ; Dr Gillies. — This is a very woody- 

 looking plant, even nearly to the extremity of the smaller 

 branches ; but the capitula have a great resemblance to those 

 of the following, and the leaves are so variable on others of 

 this genus, that we know not where to draw the limits of 

 the species.
