LlLIACEiE. 



QUAMASIA ESCULENTA (Nutt.) Raf. 



Frequent on the banks of the Huron near Rockwood, No. 4149, May 

 21, 1916. Nuttall was the first to discover and name this species. The 

 original habitat or type locality is "near the confluence of Huron River 

 and Lake Erie;" the station at Rockwood, the only one at present known 

 which might come witliin the limits of the type locality, may be the 

 identical place where Nuttall originally found the species. Rafinesque 

 established the genus Quamasia in 1818, naming one species, Q, esculenta, 

 which by many present day botanists is considered to be the western 

 Q. Quamash (Pursh.) Coville. I have not seen Rafinesque's publica- 

 tion, but in his Medical Flora II, 255, 1830, his concept of his Quamasia 

 esculenta is exactly that of Nuttall's, i. e., it includes both the eastern 

 Camassia Fraseri Torr. and tlie western C. esculenta Lindley. If the 

 above is the proper interpretation to be applied to Rafinesque's 

 Q. esculenta, then it has been erroneously referred to the western species. 

 Nuttall's species (Phaser's Catalogue, 1813, and Genera I, 219, 1818) 

 was based on plants collected by Nuttall himself in 1810 at the type 

 locality above cited; he also included the western plant under the im- 

 pression that it was the same species. Rafinesque's name, if based upon 

 Nuttall's, as is probably the case, must of course belong to the eastern 

 species.
