268 DECANDBIA DIGYNIA 



flowers sccund and nodding, finally erect \ pedicels varying from 1 line to an inch 

 or more in length. Petals somowhat connocted below ; outer ones spalulatc-oblong, 

 gibbous at base, with a nectariferous cavity within ; tho alternate ones narrower, 

 linear-oblong, or oblanceolate. Stamens mostly 8, shorter than the petals \ fila- 

 ments hairy, alternating at base with short detlexed pubescent tooth-like pro- 

 cesses ; anthers short , broad-ovate, or subreniform, opening outwards their whole 

 breadth, tho outer or lower lip much larger, spreading horizontally, and finally 

 revolute. Ovary ovoid, obtusely oangled, grooved, hairy ; style thick, as long or 

 often longer than the stamens ; stigma large, orbicular f concave, with a densely 

 bearded margin. Capsule roundish-ovoid ; dissepiments growing to the axis near 

 the base, thereby preventing tho valves from expanding.

OyK-FLowEBED Monotuopa. Vulgo — Indian Pipe. Bird's nest. 



Whole plant white and smooth, becoming purplish black in dryiug. Root pe- 

 rennial? roundish, composed of brownish fleshy densely-matted brittle fibres, 

 parasitic? Scaped to 8 or sometimes 12 inches high, simple, succulent, often grow- 

 ing in clusters, furnished with lance-ovate scales. Flower large, at first nodding, 

 finally erect. Petals concave, spatulatccuneate, truncate, gibbous at base, smooth 

 externally, hairy within, and ciliato on the margins t>elow. Stamens shorter than 

 the petals ; filaments hairy, alternating at base with short deflexed smooth tooth- 

 like processes ; anthers subreniform, opening by 2 transverse margined foramina. 

 Ovary large, ovoid ; style short, thick ; stigma overtopping the stamens, large, 

 orbicular, concave, margin not bearded. Capsule ovoid, obtuse, pentangular. 

 Seeds minute. 



Hob. Woodlands: frequent. Fl. June-July. jFV. September. 



Obs. This species is more common than the preceding. Thcso singular plants 

 are called parasitic; but I cannot eay that their usual mode of growth corresponds 

 exactly with my notions of a genuine parasite. They certainly often seem to be 

 totally unconnected with any other plant. One or two additional, but rather doubt- 

 ful sjHJcies, have been enumerated in the U. States.
