Magenta to Pink 



and so letting fall a few soft pellets of pollen on it. Now, after 

 he has drained the next arethusa, his pollen-laden head must 

 rub against the long sticky stigma before it touches the helmet- 

 like anther lid and precipitates another volley of pollen. In some 

 such manner most of our orchids compel insects to work for them 

 in preventing self-fertilization. 



Another charming, but much smaller, orchid, that we must 

 don our rubber boots to find where it hides in cool, peaty bogs 

 from Canada and the Northern United States to California, and 

 southward in the Rockies to Arizona, is the Calypso {Calypso 

 bulbosa). It is a solitary little flower, standing out from the top of 

 a jointed scape that never rises more than six inches from the solid 

 bulb, hidden in the moss, nor boasts more than one nearly round 

 leaf near its base. The blossom itself suggests one of the lady's 

 slipper orchids, with its rosy purple, narrow, pointed sepals and 

 petals clustered at the top above a large, sac-shaped, whitish lip. 

 The latter is divided into two parts, heavily blotched with cinnamon 

 brown, and woolly with a patch of yellow hairs near the point of 

 the division. May — June. 



Calopogon; Grass Pink 



{Limodorum tuberosum) Orchid family 

 (Calopogon pulchellus of Gray) 



Flowers — Purplish pink, i in. long, 3 to 15 around a long, loose 

 spike. Sepals and petals similar, oval, acute ; the lip on upper 

 side of flower is broad at the summit, tapering into a claw, 

 flexible as if hinged, densely bearded on its face with white, 

 yellow, and magenta hairs {Calopogon = 'bt2i\it\M beard). 

 Column below lip (ovary not twisted in this exceptional 

 case) ; sticky stigma at summit of column, and just below it 

 a 2-celled anther, each cell containing 2 pollen masses, the 

 grain lightly connected by threads. Scape : i to i ^ ft. high, 

 slender, naked. Leaf: Solitarj;, long, grass-like, from a round 

 bulb arising from bulb of previous year. 



Preferred Habitat — Swamps, cranberry bogs, and low meadows. 



Flowering Season — June — ^July. 



Distribution — Newfoundland to Florida, and westward to the Mis- 

 sissippi. 



Fortunately this lovely orchid, one of the most interesting of 

 its highly organized family, is far from rare, and where we find 

 the rose pogonia and other bog-loving relatives growing, the cal- 

 opogon usually outnumbers them all. Limodorum translated
