I finally spoke with the photographer, Denny Curtin, last night. I strongly encourage you to revisit his site.
He's updated his photo journal in the last month with two more trips - one local and one to Santa Barbara. Photographing indigenous plants and animals is his passion and he picks a local woodland area and visits it for a year to capture all the plants and critters with different seasonal cycles.
I learned Cyp. acuale (aka pink lady's slipper)
which I've seen in NH, but never in Mass, do grow locally. He told me all the locations he's seen them (but never in great numbers.)
He also mentioned several other local orchids:
Rattlesnake plantain (Goodyeara pubescens):
Lady's tresses (Spiranthes cernua):
Green wood orchid (Platanthera clavellata):
He's invited me on his next woodland tromp, which should be fun!
Ok...now the good stuff. He gave permission to post the funeral photo I described earlier in this thread. He's very interested in comments and we can probably entice him to register on the forum!
