to conceal the folding of the next year's fronds, which fully agrees 

 with Mr. Davenport's description of the bud of ternatum. Dr. 

 Haberer says it is later in maturing than the other varieties.

 inches high, stipites separating l / 2 to 1 inch above the root, both 



stipites stout, but not as strong 

 as in var. intermedium. Stipes 

 of leaf 3 inches long, leaf 3 to 4

 1 to 1^ inches long, X to H °* 

 an inch wide at base, sometimes 

 deeply pinnatifid ; stalks of lower 

 pinnae each with 3 to 4 rounded 

 lobes cut nearly to the costa, and 

 a terminal one; lobes round -

divided form of the species and 

 is apparently the least common. It was found in only two localities, 

 on the flat of a stream in Deer field, Oct. 15. Years ago I found the 

 same form in the Mohawk valley; and in 1898, after Dr. Under- 

 wood had published his monograph on th -1 ternate Botrychia, I 

 sent him a tracing of the plant, asking him where it should be 

 placed. He answered as follows: "Whether your tracing labeled 

 ' Mohawk river plant' is an enlarged form of same (sub-var. inter- 

 jnedium D. C. E ), or is Eaton's northern N. Y. type of his var. 

 australe I cannot say. It does not match either, nor is it typical 

 obliquum." I have waited thus long to have some one give the 

 variety a name and description, as it has doubtless been found in 

 other localities; but these plants having come into my hands, it 

 seems to have devolved upon me to name it. So I have given i* a 

 title which w'll show that the type came from Oneida County, N. Y. 



In this variety the tendency to be ternate is not always so 

 pronounced as in var. obliquum. Sometimes it seems to be almost 

 regularly pinnate, and sometimes the basal pinna is inch low- - r 

 on the rachis than the one that should be opposite. 



There is no doubt that the ternate Botrychia are long-lived 

 plants, and increase in size from year to year. But even the first 

 year they produce a little spike of fruit which corresponds in size 

 and development with the little ternate leaf. Apparently they
