Sonoran ; and such a map would have little value unless it were 

 made out in two forms — one for the wet and one for the dry season. 

 Specimens of all the plants named below, unless otherwise 

 indicated, have been deposited in the Gray Herbarium. Mr. 

 J. Francis Macbride has very kindly verified and corrected my 

 determinations in the case of all except the sedges, which have 

 been submitted to Mr. K. K. Mackenzie and remain in his pos- 

 session. All these specimens were found growing spontaneously, 

 and I have omitted several that, although common, seem still 

 dependent upon cultivation. No species collected outside the 

 limits of Piper and Beattie's Flora has been included.
