CALOPOGON; GRASS PINK (Calopogon pulchel- 

 lus) is an exquisite orchid with a loose raceme of 

 four to twelve delicate pink flowers, at the top of a 

 scape ranging from 6 to 15 in. long. The flowers are 

 apparently upside down as the lip is at the top; it is 

 narrow at the base but broadens into a broad hook- 

 ed tip, crested on the under side; the column, just 

 below the lip, has a stigma at the end, and just below 

 is a two celled antler, each cell containing two 

 pollen masses. A single grasslike leaf sheathes the 

 flower scape near its base, as it rises from the solid 

 bulb. It grows in deep swamps and bogs, from New- 

 foundland to Minn, and south to the Gulf, flowering 

 in June and July. 



ARETHUSA; INDIAN PINK (Arethusa bulbosa) 

 has a solitary magenta-pink blossom topping its slend- 

 er scape that rises from 5 to 10 in. in height. The 

 petals and sepals are similar in shape and in their 

 proper positions at the top of the flower; the lip 

 rises, then abruptly turns downwards, broadens and 

 is adorned with three to five yellow and white crests; 

 margin of lip wavy and sometimes spotted with crim- 

 son. A single linear leaf is hidden in a sheath at 

 the base of the scape; it only protrudes after the 

 flowering season. From Newfoundland to Minn, and 

 south to Pa. and Mo., Arethusa has been found bloom- 

 ing in swamps during May and June. 



CALYPSO (Calypso bulbosa) is a rare and local- 

 ly distributed orchid found along the northern edge 

 of the U. S. and in Canada. It has a single magenta- 

 pink flower at the top of a slender scape 4 to 8 in. 

 long. The sepals and petals are similar and ascend- 

 ing; the lip is sac-shaped similar to that of the genus 

 Cypripedium; it is spotted with madder-purple and 

 has three rows of glass-like hairs near its division. 

 A single oval, wavy, veiny leaf grows on a triangular 

 petiole from the corm at the base of the scape.
