2l8 PATAGONIAN EXPEDITIONS I BOTANY. 



valley of Rio Leona, at Lago Viedma, in valley of Arroyo Scheuen, etc. By 

 Lagasca stated to occur in the Falkland Ids. (mistake?). It is doubtful 

 if the Hatcher specimen here cited does not belong to a different species. D. 



P. 690 : 



VERBENA TRIDENS Lag. 

 Syn. Verbena carroo Speg. 



This species is one of the commonest characteristic plants of S. Pata- 

 gonia and of the southern section of Mid-Patagonia. Its range extends 

 over the table-land, at least from Rio Gallegos to Lago Buenos Aires and 

 on the east coast to the north of Golfo de San Jorge. It occurs also in 

 the small transverse valleys between the river valleys, as well as here and 

 there in the flat bottom of the main valleys, but does not thrive in the 

 section near the forest district, and is there very rare. The southernmost 

 locality known to me is situated in the Baguales district. 



Philippi has, as far as I am aware, never identified V. tridens Lag. with 

 V. carroo Speg., but the very brief description of the former given by 

 Lagasca, as well as the more detailed description given by Philippi 

 Anal. Univ. Chil. Tom. xc, p. 612, shows clearly the identity of the species. 



The inflorescence is not always so short as in the specimen figured in 

 Flor. Pat, plate xxiii, but sometimes it is elongated, attaining a length 

 of about i dm. or still more. 



In my work die Gefasspflanzen der Magellanslander, p. 132, a mistake 

 has been made, to which I may be allowed to call attention. Under 

 Verbena tridens Lag. I cite; "Phil. Plant. Nuev. Chil.," etc., adding from 

 inadvertence: ("Sub. nom. Verbenae tridactylitis.") The last clause is 

 incorrect and should be struck out. D. 



P. 690: 



V. UNIFLORA Phil. var. GLABRIUSCULA Ok. 



Should be struck out, being, according to F. Kurtz, Collect. Flor. 

 Argent., p. 249, identical with Benthamiella patagonica Speg. The species 

 itself represents, according to Briquet in Engler und Prantl, die nat 

 Pflanzenfam. Beitrage, II, p. 66, the type of a new section Paziciflorce of 

 the gen. Verbena. (This view will retain it in Verbena. G. M.)
