80, as Polystichum acrostichoides, f. cristatum Clute. 
The plant was found in the woods among others; since 
it is in cultivation, only the fertile fronds are crested. 
From these I raised some sporelings which are now in 
their third year and I hope will show some crests this 
next season. Mr. Huss, of Hartford, has taken charge 
of these young plants. 
The other is a crested, or more correctly, furcated form 
of Asplenium platyneuron. I found it growing on a 
bank near an old cemetery. There was a little colony 
among the ordinary ones which covered the whole bank. 
Like Polystichum acrostichoides, only the fertile fronds 
are fureated. I removed a few plants to the fernery, 
and from them I had good spores, which are now in 
the prothallium stage and will show better what they 
willdo. They are also in Mr. Huss’s care.

incidental answer to the question ‘What is the habitat 
of Ophioglossum vulgatum?” has just been published by 
Miss Norma Pfeiffer* in connection with an account of 
some prothallia of this species found near Chicago. 
The species was found in two localities, one moist, and 
subject to flooding, the other drier. The prothallia 
were found only in the moist situation, and the sugges- 
tion was made that probably only in moist places are 
the spores able to develop into prothallia. A correlated 
Suggestion was made that in dry places reproduction 
must be by means of buds from the roots. Another 
observation recorded was to the effect that in the moister 
locality, the spores were discharged practically two 
weeks earlier than in the other. The prothallia were
