 or mistaken for tlie next, as in the collections of Douglas and Hartweg.

 Same range as the last, but not known so far northward or eastward. To this 

 belong many specimens referred by Dr. Torrey to the next species, and also 

 so referred by Watson in Bot. King. Expl. Perhaps the Mijosoiis muricata of 

 Ruiz & Pav., and Eritrichiuni alyssoidcs DC, of Chili, are the same thing. Very 

 likely this species is not Hooker and Nuttall's Mijosoiis muricata, as I have not 

 seen it in Douglas's Californian collection. The plants which I possess of that 

 collection, upon one or the other of which J/, muricata would seem likely to have 

 been founded, are, one of them my E. oxijcanjum, which is more probably what 

 was referred to M. Jlaccida ; the other one, E. canescens without fruit, which 

 therefore may represent M. muricata Hook. & Arn.

 W. Arizona and adjacent part of California. It is no. 500 of Coulter's collec- 

 tion ; and no. 76 of that of Xantus in Lower California was correctly referred 

 to it. But specimens of other species, notably of the preceding, have been con- 

 founded with it.
