spicate, fragrant, 2-bracteolate at the base, 
spreading or erect, the spike at first recurved, 
becoming erect, 1/-2’ long; sepals mostly ob-

late-filiform; anthers short, peltate, horizontal, opening at first by 2 transverse chinks, be- 
coming transversely 2-valved. Disk 10-12-toothed, confluent with the base of the ovary. 
Ovary 5-celled; style short, thick; stigma funnelform, its margin obscurely crenate, not

1. Monotropa uniflora L. Indian 
Pipe. (Fig. 2739.) 
Monotropa uniflora ¥,. Sp. Pl. 387. 1753. 
Scapes white, glabrous, usually clustered, 4/— 
10’ high from a mass of matted brittle roots, 
turning dark in drying. Flower terminal, in- 
odorous, nodding, oblong-campanulate, 14/-1/ 
long, the fruit becoming erect; petals 4-5 
(rarely 6), puberulent within, white, rather 
longer than the usually 1o stamens; filaments

the short style; capsule erect, obtusely angled, 
5/’-8” high, 4//-5’’ in diameter. 
In moist rich woods, Anticosti to Florida, west 
to Washington and California, almost throughout 
temperate and warm North America. Ascends to 
4200 ft. in North Carolina. Alsoin Japan and the 
Himalayas. Whole plant occasionally pink or red.
