A. CRISTATUMXMARGINALE AND A. SIMULATUM 77 
contained articles by Mr. Davenport relating to this 
fern. It is the same which for years has been known as 
A. cristatum, var. Clintonianum which, however, does 
not grow in eastern Massachusetts. But, nevertheless, 
our fern, until I showed that it was a probable hybrid, 
had always been known as var. Clintonianum. Several 
specimens in the herbarium of the Peabody Academy of 
Sciences are tagged in this way, one or two of them are 
among the specimens of A. cristatum, and it is fair to 
presume that in the herbarium at Cambridge there are 
some fronds of this hybrid marked cristatum Clintoni- 
anum. 
But var. Clintonianum is as much a product of calea- 
reous soil as are A. Goldieanum or Cystopteris bulbifera. 
I have had a half dozen plants of Clintonianum under 
cultivation, some from western Massachusetts, and some 
from New York. One of these plants was sent me by an 
attorney of Buffalo after an examination of Judge Clin- 
ton’s specimens in the herbarium of the Buffalo Academy 
of Sciences. I received this fern with the understand- 
ing that it was taken from the identical swamp where 
Judge Clinton collected his plants. These plants of A. 
cris|tatum| Clin{tonianum] are unlike the plants of A. 
cris[tatum] x marglinale] although the books have made 
no distinction between them. The idea I have regard- 
ing the fern which has been named var. Clintonianum 
and especially regarding Judge Clinton’s plant is that it 
is a hybrid between Aspidium Goldieanum and Aspidium 
cristatum. They have every appearance of this and I 
think the subject should be investigated. 
ASPIDIUM SIMULATUM 
In August, 1891, Mr. William H. Swasey of Newbury- 
port showed me a peculiarly shaped frond which he had 
taken from a fern growing at the “‘ Pines,’ so called, at 
Newburyport. This frond had somewhat the appear-
