224 MB. J. BALL ON THE FLOBA OF NOBTH PATAGONIA 



Senecio labicifolius, H. B. K. ? A small shrub from the 

 plateaux of North Patagonia (No. 209, G. C). This is a poor 

 specimen, but it agrees with one collected by Darwin near Bahia 

 Blanca, and thus labelled in Kew Herbarium. It agrees pretty 

 well with the description of Kunth. Nevertheless I do not feel 

 sure of the specific identity of this and the Peruvian plant. 



Senecio ? Bahia Blanca (No. 205, G. C). A very im- 

 perfect fragment, looking like S. oligoleucos, Baker. 



Cnicus lanceolatus, L. Introduced from Europe of late 

 years, now widely spread in the district of Bahia Blanca. Called 

 in Spanish Cardo negro. 



Hvalis abgentea, Bon. Bahia Blanca and North Patagonia : 

 one of the characteristic plants of this region (No. 104, G. C). 

 Tbe Spaniaids call this Oliva and also Ma qui bianco. The resi- 

 nous excrescences on the stem caused by insects are gathered by 

 the Indians, and used as a masticatory. 



Chttqtjibaga ebinacea, Bon. Widely spread through North 

 Patagonia from the Atlantic coast to the Cordillera, the northern 

 limit being about Bahia Blanca (No. 82, G. C). The Arauca- 

 nian name is TscMtri JceTcelu. 



Chtjquibaga hystbix, Bon. North Patagonia, northern limit 

 some way south of the Kio Negro, extending thence to the 

 Chubat and beyond that river, very common in some parts 

 (No. 148, G. C). A shrub 4-5 feet high, with the heads (invo- 

 lucral scales) bright yellow, flowering in summer (December and 

 January). The leaves prick like needles, but easily drop off 

 from the dried specimen. This is a larger and stronger plant 

 than the allied C. erinacea. The leaves, which are quite glabrous, 

 are broader below, terminating in a sharp brown point. There 

 is slight araneous pubescence (cobweb) about the margin of the 

 involucral scales. 



Chuquibaga Kingii, n. sp. Extends from the mountains of 

 Treneta southward to the Chubat and beyond that river (No. 146, 

 G. C). I have received but a very incomplete fragment of this 

 undescribed species, but it is evidently the same as two speci- 

 mens in the Kew Herbarium ; the first, from Port St. Elena, col- 

 lected by Captain King, the second, labelled "Patagonia," from 

 Captain IVliddleton. I subjoin a brief diagnostic character which 

 may serve to identity the plant.
