evoliitis multifidisintcrdum confertis et apotheeiis symphyearpis." 

 This description applies well to this specimen, in which there is a 

 decided reaction K+ in the folioles, and would seem to point 

 to its separation from squamosa, which has a different reaction, 

 K-. 



22. " CI. sqimmosa, Hoffm,, v. ventricosa, Fr., glahriuscula." 



Here, again, there is the reaction K-j- in the folioles of the 

 podetia ; and it may probably be also referable to frondosa, Del, 



23. " CI. squamosa, Hoffm,, v. asperella (Flk,), Korb." 



K-C-. 



24. " CI. furcata, Hofftn,, v, stricta. Wall, (syn, v. stenozosia, Mass. 



Ital. 196)." 

 K+ C + . =Tuck. L, Amer. 33, but with slight reaction. 

 Mass, Ital. 196 has full reaction, K + C + j and is therefore 

 referable to pungens. 



25. " CI. furcata, Hoffm., v. racemosa, Hoffm." 



K+ C + . =Coem. 183. This specimen has so decided a 

 reaction that I cannot hesitate in referring it as a state of 

 CI. pungens, var. foliosa. 



26. " CI. furcata, Hoffm., v. corymhosa (Ach.)." 



K+ + . =Coem. 189. The decided reaction refers this 

 also to CI. pungens. 



27. " CI. pungens (Ach,), Fr,, f, foliolosa." 



K+C + . The true plant, 



28. " CL jJMw^ms (Ach,), Fr., f, v«7«?a, Rabh. (syn. CI. mimvata, v, 



Euganea, Mass, Ital. 191)." 

 Iv-f C + . In my co2)y of Mass. Ital., No, 191 is a much 

 stronger plant, and different in asjDcct from this specimen. 



29. " CI. pungens (Ach,), Fr," 



K+ C + . =Mudd, 54 & 55 ; M. & N. 754 ; Leight, 16. 



30. " CI. pungens (Ach.), Fr." 



K+C + . 



31. " CI. degenerans, Flk., t. pleolepis, Ach," 



K+ C + . The decided yellow reaction makes this ^epldota, 

 Ach, 



32. " CI. degenerans, Flk,, f. pliytlocepliala, Wallr., Kiirb." 



K4- C + . The decided yellow reaction refers this also to 

 lepidota, Ach. 



33. " CI. gracilis, Hoffm., v. aspera (Ach.), Flk." 



K + C + . The reaction and aspect refer this to CJ. pungens, 

 var. foliosa. 



34. " CI. gracilis, Hoffm., v, ehngata (Ach,)." 



X4- C + . The reaction and the peculiar character of tlic 

 cortical layer identify this with CI. ecmocyna, Ach. 



35. " Ch cornucopoides (L.), Fr., v. extensa, Hoffm."
