PATAGONIAN EXPEDITIONS: BOTANY. 



Central Chili in the Cordilleras; N. W. Patagonia, Rio Puelo; W. 

 Patagonia, Rio Baker. 



Add Macloskie, p. 896 : 



PEREZIA VARIABILIS Phil. 



Radical rosettes of linear, spatulate-oblong leaves, attenuate to petiole, 

 entire or lobed, 5-8 cm. Scape solitary in each rosette, many times 

 longer, with 1-3 leaves. Head solitary, blue; involucre-scales 15 mm., 

 linear, the outer pointed and toothed. 



S. Chili, in the Cordilleras ; N. W. Patagonia, Rio Puelo. 



HYPOCHCERIS Linn. 



The material requisite for revising this genus is unfortunately wanting, 

 and I am therefore compelled to content myself with a few remarks. D. 



P. 896 : 



H. ARENARIA Gaud. 



Skottsberg asserts that our Patagonian specimens have nothing to do 

 with H. arenaria of Gaud., which he knows from its original home in the 

 Falkland Isles. He regards our specimen as a glabrous form of H. 

 coronopifolia. 



P. 898: 



H. BRASILIENSIS Gris. 



Scarcely found in N. Patagonia ; it may probably be deleted. 



H. CORONOPIFOLIA (Comm.) and H. INCANA Hook. & Arn. 



Are in my opinion identical. H. incana should be deleted, as H. 

 coronopifolia has priority. D. 



H. HOOKERI Phil. 



Syn. H. stenophylla Dus. Dusen, Neue u. selt. Gefasspfl. Archiv. 

 fiir Botanik, p. 49, Taf. 5, fig. 2 ; Taf. 9, figs. 1-2. 



In S. Chili, in the Cordilleras ; S. Patagonia, on sandy steppe by Manan- 

 tiales (Richmond, near Sta. Cruz Emporium); near Lago Argentine on 

 sandy steppe ; Lago Viedma on drifting sand.
