2l6 PATAGONIAN EXPEDITIONS : BOTANY. 



VERBENA GLAUCA CISANDINA Nied. 

 Occurs in N. Patag., Territory of Neuquen. 



P. 686: 



V. INFLATA H.B.K. 



According to Macloskie this species was collected by Hatcher in S- 

 Patagonia, at Rio Sta. Cruz. Though I have not had opportunity of 

 seeing any specimen, the occurrence of this species in S. Patagonia 

 seems to me to be doubtful by reason of the distribution of this plant. 

 The specimens collected by Hatcher have been compared by Macloskie 

 in the Gray Herbarium. I may, nevertheless, be allowed to express a 

 slight doubt as to the correctness of the determination. D. 



P. 686: 



V. INTERMEDIA Gill. & Hook. 



The southernmost locality of this species is at Sierra de Curumalan, in 

 Argentina, near Buenos Aires, and it is scarcely to be found in our district. 



P. 686: 



V. LIGUSTRINA Lag. 



Should be substituted instead of its syn. Verbena Lorentsii Nied. 

 Lorentz & Niederlein, Exp. Rio Negro, p. 264, pi. XII, f. T. Hieronymus, 

 Sert. Patag., p. 370. Described Fl. Pat, 686, no. 15. 



Rather common, at least in Mid-Patagonia and S. Patagonia. 



Though Lagasca's description of V. ligustrina is brief and incomplete, 

 it, nevertheless, seems to me to be evident that V. lorentzii Nied. is 

 synonymous with V. ligustrina Lag. 



This species is rather variable as to the form and size of the leaves and 

 inflorescence. The most striking description is that given by Hieronymus. 

 Comparing Lagasca's description with that by Hieronymus an exact 

 accordance is to be stated between them, as the following parallel shows : 



LAGASCA. 



folia ovato-oblonga, scabra ; marginibus revo- 

 lutis, integerrima ; spicae cylindracese, termi- 

 nates. 



HIERONYMUS. 



folia linearia vel ovato-oblonga, utrinque sca- 

 briuscula ; marginibus revolutis integra ; spies 

 multiflorae, i ^-6 cm. longae. 



Lagasca's brief description corresponds very well with Verbena lorentzii
