1. Monotropa uniflora L. Indian Pipe. Map 1572. A saprophyte on 

 humus in several types of habitat but usually in black and white oak woods. 

 I once found a large clump of large plants growing in sphagnum in a 

 tamarack bog. The species is well distributed in the state but ordinarily 

 infrequent. In the low woods on the north side of the Kankakee River 

 south of Schneider in Lake County, however, it was so common that 

 it reminded one of a woods in winter when the snow was on the ground. 

 Acres of this woods were carpeted with it. I revisited this woods several 

 years at the same time of the year but I was able to find only a plant 

 here and there.

2. Monotropa Hypopitys L. var. rubra (Torr.) Farw. (Amer. Midland 

 Nat. 10: 39. 1926.) {Monotropa Hypopitys L. of Gray, Man., ed. 7 and 

 Hypopitys lanuginosa (Michx.) Nutt. of Britton and Brown, Illus. Flora, 

 ed. 2.) Pine-sap. Map 1573. Saprophytic on slightly acid humus in dry or 

 moist woods. Infrequent to rare, possibly in all parts of the state. In 

 addition to the counties indicated on the map it has been reported from 

 Cass, Franklin, Hamilton, Marion, Vigo, and White Counties. Usually found 

 sparingly in black and white oak woods. I found it in Clark County, how- 

 ever, as an abundant plant in a low, flat, beech and sweet gum woods where 

 the soil is a hard, white, slightly acid clay. The stigmas of all of our 

 Indiana plants are pubescent.
