DECANDRIAe MONOGTNIA. 271 



Side 5- celled, 5-val\ed. Seeds very numerous, 

 minute, subulate. 



Parasitic plants growing upon the roots of trees, desti- 

 tute of proper leaves and verdure; root densely squamose, 

 scales imbricated; stems aggre^iated, simple, invested 

 with alternate scales; flowers racemose, pedicellate, ra- 

 ceme at first bent, at length erect. Scent of the whole 

 plant musky. 



Species. 1. H. *europcea. {Moyiotropa Hypopithys. Sp. 

 PI.) In the pine-forests of Canada. 2. lannginosa. Ob&. 

 Every part of ihe plant pubescent except the base of the 

 stem and lower scales; scape more or less convolute and 

 angular (often triangular;) peduncles nearly an inch long. 

 Calix inconstant in the number of its segments; filaments 

 pubescent, alternated at the base by 10 very short recurv- 

 ed filit'orm appendices; anthers excentrically peltate or 

 rather rivetted to the filaments on one side, somev/hat 

 coriaceous, persistent, and opaque, almost reniformly di- 

 lated, opening outwards their whole breadth, and at 

 length becoming revolute. Style pubescent^ stigma orbi- 

 cular; somewhat depressed, internally partly 5-lobed» 

 margin bearded. Dissepiments of tlie capsule coalescing 

 in the axis towards the base; consequently the fruit never 

 expands, as is also the case with Pyrola, thejmargins of the 

 capsule merely shrinking for the purpose of dissemina- 

 tion. 



88. MONOTROPA. L. 



Calix none. Corolla pseudo-polypetalous, 

 persistent; se^^ments 5, each with a cucullate, 

 nectariferous base. Jlnthers reniform, horizon- 

 tal, 1-ceIled, emitting the pollen near the mid- 

 dle, by 2 transverse foramina. Stigma orbicu- 

 lar, naked. Capsule 5-celied, 5-valved. Seeds 

 very numerous, minute, subulate. 



Parasitic plants, mostly upon the roots of trees, desti- 

 tute of proper leaves and verdure; root an agglomeration 

 of intricate succulent fibres producing many 1-flowered 

 scapes or stems, scapes squamose, flowers at first nutant, 

 primarily incurved. The whole plant white and smooth, 

 destitute of the musky odor of Hypopithys, scent when 

 bruised somewhat nauseous and liliaceous. 



Species. 1. M. morisoniana- 2. unifiora. Obs. Root 

 perennial? roundish, about tht size of a walnut, composed 

 of a vast number of intricately ramified and agglomerated
