Notes on Govillea and Fagonia 



? 



By Anna Murray Vail 



Dr. B. L. Robinson (Syn. FI. i: 356) has pointed out that 



r 



the leaflets 



Larrc^ 



more widely spreading and arc less inclined to be falcate as well as 

 more decidedly connate than are those of Larrca Mcxicana, 



M 



F. V. Coville recently (in litt.) also claims that however closely 

 related, the southwestern species is distinct from the Chilian 

 species. The plant on which I based my examination of Larrca 

 divaricata w^as a duplicate of the '' Macrae ''specimen mentioned 

 by Dr. Robinson and it is undoubtedly Z. Mcxicana, Since then 

 I have seen the following specimens from South America (Her- 

 barium of the British Museum) }^\\\yo\'\.mgio he Larrca divaricata r 

 Lorenz, no. 105 ; Cordoba, G. Hieronymus, ** 5, 6, 1877"; South 

 Am., Pearce ; Chili, Bridges, 1843, and a specimen from Fata-

gonia which is identical with one from Rio Negro, North Pata- 

 gonia, from the Wilkes expedition in the Herbarium of Columbia 

 University. They all agree with the differences referred to by Dr[ 

 Robinson and in addition I will add that they do not appear to be 

 quite so resinous as the North American plant and the fine silky 

 pubescence of the young leaves seems to be more abundant and 

 to persist longer ; the venation is also more distinct. There are 

 some North American specimens, however, which approach very 

 closely to L. divaricata and among them I noted one collected at 

 " El Paso, New Mexico," by H. Carruthers, Nov. lO, 1884, in the 



I 



Herbarium of the British Museum and a specimen without flow^ers 

 or fruit collected by Fremont on his expedition to California in 



1849 (Herb. Torrey). 



The synonymy of these two species should therefore stand as

follows :
