CRANE-FLY ORCHIS, Tipularia unifolia, is a rather 

 rare little summer orchid, with purplish-green, long- 

 spurred, racemed blossoms. It bears one leaf after the 

 flowers.

 brown and purple flowers and an autumnal leaf. 



PLATE XVI 



GRASS- PINK, CALOPOGON, Limodorum tuber osum (Calo- 

 pogon pulchellus}. Root. A round, solid bulb. Stem. 

 Slender, simple, i-ij high. Leaf. One, grass- 

 like. Flowers. Showy, in a few-flowered, terminal 

 raceme, rose-purple. Perianth. Of ovate sepals and 

 petals, and an erect, pale-pink lip, with a tuft of yellow 

 wool. Column (A). Petal-like above, winged, spread- 

 ing horizontally. The anther (a) is attached to the back 

 of the column. The stigma 0) is beneath. Ovary (o). 



This dainty plant waves its blossoms among the tall 

 grasses of the wet marshes, in June and July, from New- 

 foundland to Florida and west to Minnesota. This 

 orchid's peculiarity is an ovary which is not twisted, so 

 consequently, the lip is on the upper instead of on the 

 lower side of the flower. 



RATTLESNAKE PLANTAIN, Peramium repens (Goodyera 

 repens'}, is a small orchid, with a rosette of ovate, green 

 and white blotched leaves at the base of the stem, and a 

 one-sided spike of small, greenish-white flowers, with a 

 sac-shaped lip. 



DOWNY RATTLESNAKE PLANTAIN, P. pubescens, is 

 woolly, with a thicker spike (not one-sided). 



These two range on the Atlantic coast and west to 

 Minnesota. 



MENZIES' RATTLESNAKE PLANTAIN, P. Menziesii, is 

 sometimes without the white mottling. It has a swelling, 

 pointed lip (not sac-shaped), and the spike is somewhat 

 one-sided. It grows in Canada and on the Western coast. 



These all bloom in July and August and are insignifi- 

 cant except for their showy leaves. 



SHOWY ORCHIS, Orchis spectabilis. Root. Fibrous. 

 Stem. Stout, five-angled, 4'-! 2' high. Leaves. Large,
