250 PATAGONIAN EXPEDITIONS: BOTANY. 



long, fleshy; stamens exsert; fruits large, compressed, ancipital, dorsally 

 keeled. 



W. Patagon., viz., its northern section, at Rio Puelo, and Rio Aysen, 

 and Nahuel-huapi, nearly 4,500 m. above the sea-level. 



17. VALERIANA FONKII Phil. var. SPICIFORMIS Dus. nov. var. (Plate III.) 



Differt a typo foliis omnibus rosulatis scapo nullo vel brevissimo, 

 pedunculis brevissimis, floribus dense spiciforme congestis. 



The plant has a very peculiar appearance and reminds us of a Viola of 

 the well-known Andine type ; it is, however, a true Valeriana. Having 

 collected, some years ago, V. fonkii Phil., on the mountains of the upper 

 Rio Aysen, I found it a very easy task to point out its correspondence, 

 in most respects, with the present plant. The variety has just the same 

 flowers, bracts, leaves and fruits as the type, but differs in having more 

 numerous and crowded flowers, more numerous leaves and very short 

 scape or none at all. The plant was collected by J. Koslowsky in Mid- 

 Patagonia in the district of Lago Buenos Aires. D.

DlPSACUS SILVESTRIS Huds. 



Any evidence of its occurring in our district is unknown to me. D. 



D. fullonum L., the Fuller's Teasel, has a shorter involucre than D. 

 silvestris Huds.; and stiff chaff, with hooked points, and has escaped from 

 cultivation in many places. It occurs in N. Patagonia, Territory of 

 Neuquen, here and there abundant, according to F. Kurtz (introduced). 

 Die Naturl. Pflanzenfam., states that it is a culture form of D. ferox Lois. 

 Macloskie refers to it as "supposed to be a cultivated variety of this 

 species"; Dusen states that he is not in a position to decide the question 

 of D. fullonum having been introduced into North Patagonia.
