Both of these forms are well represented in the Daven- 

 port Herbarium, and to my positive knowledge are to be 

 found in some other herbaria as well. Walter Deane has 

 a very fine example of compositum from Mt. Tobey in 

 his herbarium, and it has been collected with nearly all 

 of the other forms during the past season by Miss Rooney 

 of St. Johnsbury, Vermont, who has favored me with 

 some fine duplicate specimens of the same. She has also 

 sent to me a fine tracing of a double specimen of incisum, 

 the two fronds being united at the rootstock. 



As to Milde's var. fallax, it clearly rests upon a single 

 character, and, according to my view of it, has not been so 

 very unusual in collections of late years. This so-called 

 variety was established by Milde on a. form of var. inci- 

 sum with the lamina above the middle of the frond, and 

 nothing can be clearer than the fact of the lamina hap- 

 pening to be incised in his plants, having nothing what- 

 ever to do with the establishment of the variety, which 

 rests wholly on the position of the lamina in its relations 

 to the common stipe. This being so, it follows that any 

 specimen having the lamina above the middle of the 

 frond constitutes the var. fallax, whether the lamina is 

 simple or compound ; it is, however, most likely to occur 

 in the simpler forms, such as simplicissimum and incisum. 

 In no instance coming under my own observation, or 

 within my knowledge, has the lamina ever occurred else- 

 where than low down near the base of the frond in the 

 sub-corn positum and compositum forms.

"With reference to Mr. B. D. Gilbert's note on the very 

 curious variety, Chur chics of Polypodium vulgare, it 

 would be of interest to know whether the plant is still 

 living, Mr. Gilbert's concluding notes leaving a doubt as 

 to whether it failed to survive removal, or merely to pro- 

 duce fertile fronds. Stalked pinnae in this genus, to say 

 nothing of the particular species, are quite anomalous. 

 The " corymbiense " form noted should be Cornublense , 

 it being a Cornish find. — Chas. T. Druery.
