The Ferns of New York
Marsh Fern. |
Keying-out those ferns took hours. The vocabulary of ferns is as rich and varied as the ferns themselves. Fronds, stipes and blades are the easy beginning. They key progresses to pinna and pinnules, sori and rachis. You scratch your head as the key asks you progressively more detailed questions. Is the fern aquatic? Simple, no it is terrestrial. Are the blades pinnatifid or pinnate? Pinnate, definitely. Well, wait, I think they're bipinnate. No, actually pinnate-pinnatifid. Is the stipe smooth or does it have scales, and what is their color? I didn't get much of the stipe, so I'll skip that one. Are there old fronds persistant on the rhizome? I collected a frond and left the woods. I can't check the rhizome... I usually end up keying a fern the old fashioned way: flipping through the field guide, looking at the pictures.
Those ferns were a wonderful diversion from my work at Skidmore College. Those woods were quiet, peaceful, old, and if it weren't for the mosquitoes, I might have sat in the shade for a while and just watched an old patch of ferns. I will be headed back this Sunday ( 9/2/12) to visit the campus once more before starting a new job. Perhaps I'll take an old green cape made from thick wool, and wrap myself, sit in the woods, and watch a marsh fern grow...
