than the lamina, wliicli has been given by Mr. Brown as the 

 essential character of the European plant. Sprengel again,^ 

 relying probably on my figures in Exotic Flora, has made a 

 principal character of the C. Americana to depend on the 

 bifid lamina; but in the present individuals that is quite 

 entire, as in Swartz's figure. "^ 



Miss Eastwood, who has kindly furnished the above ex- 

 tract, says: — "An examination of the specimens in the her- 

 barium of the California Academy of Sciences shows that 

 all those from the Pacific Coast have the two teeth of the 

 labellum longer than the lamina, and very prominently pro- 

 jecting, while the specimens from the mountains of Colorado 

 and one specimen from Europe have the lamina entirely 

 covering the two teeth. The specimens from the Pacific 

 Coast are:— Washington; Seattle, May, 1892 (C V. Piper): 

 Oregon; Salem {J. V. B. Smith); Portland, 1869 (Harford 

 & Dunn); Applegate Valley, Jackson Co. {H. L. Burden): 

 California; Mt. Tamalpais, near Larsen's, Marin Co. {Mrs. 

 C. BonesteU). Dr. Behr says that Dr. Kellogg found it on 

 Mt. St. Helena: specimens in the herbarium, marked C. 

 borealis in Dr. Kellogg's writing, without locality, probably 

 came from there. The specimens from Colorado are: Hall 

 & Harbour, 1862, No. 537; Palmer Lake {A. Eastwood, 

 1890). The specimen from Europe is No. 629 ex herb. Florae 

 Ingricae (Finland)." 



My Cazadero plants show great variability in the propor- 

 tionate length of the lateral and median lobes of the labellum, 

 and in the depth of division of the median lobe. In some 

 cases the connate lateral lobes (the " lamina") are decidedly 

 shorter than the saccate median lobe, in other cases the re- 

 verse condition exists; I did not notice before drying my 

 specimens, whether the " lamina " was in all cases entire, but 

 it certainly was in those of three flowers; again, in some cases 

 the median lobe is deeply bifid, with spreading teeth, in 

 other examples it is almost entire. Specimens in the herba-
