canyon we had found nine, or perhaps ten, species of 

 ferns, an Equisetum and a Selaginella. 



Just at dusk, as we were coming out of our little 

 canyon into a larger one, we found a Habenaria and a 

 broom rape (probably Orobanche tuberosa (Gray, Heller.)? 

 and a little later, when it was almost too dark to see, 

 Prof. Fitzpatrick caught sight of another Habenaria. 

 Orchids are not plentiful around here so we felt 

 peculiarly favored. It was now nearly dark and we 

 were still a long way from home, but we were agreed 

 that though tired we had spent a great and profitable 

 day.

Double Sori in Athyrium 



E. J. WINSLOW 



Three years ago, while the author was collecting in 

 northern Vermont and amusing himself by making a 

 rather minute examination and comparison of the three 

 species of our New England ferns that are sometimes 

 called Athyrium, fronds were collected from several 

 widely separate plants of a narrow, erect variety of A. 

 jilixjemina, which generally bears double sori on the 

 outer part of the pinnae where the veining becomes more 

 simple. This seemed interesting as an unusual and 

 perhaps unrecorded peculiarity of structure, and because 

 it raises some interesting questions regarding the rela- 

 tions and classification of the three species under con- 

 sideration. 



Figure 1 is an essentially accurate sketch of a small 

 portion of one of the fronds showing the outline of three 

 pinules and one pair of sori on each; the pair to the left 

 on the two branches of a forked vein, the next pair on a
