 taken for a young plant of Medeola in which only one whorl had 

 been developed.

Open bogs; occasional in the northern counties and Middle 

 tJstrict, locally common in the Pine Barrens and Cape May 

 peninsula. 



Of the three large flowered pink bog orchids of the Pines — 

 Pogonia, Limodorum and Arethusa — the last I think easily holds 

 first place. There are no leaves at flowering time, the single 

 narrow blade appearing later on, and the whole plant is sufifused 

 with pink and crimson. The bulb seems to rest loosely in the 

 sphagnum and can usually be easily lifted up, too easily for the 

 safety of the species. 



Though rare and local in some spots, in others it is exceedingly 

 abundant, and I have seen hundreds of the beautiful blossoms 

 decking the bogs near Bay Head on Decoration Day, wtiich 

 marks the height of its flowering season. 



FL — Mid-May to mid- June.
