 shining leaves, somewhat whorled or scattered along the short ascending stems ; 

 the fragrant (white or purplish) flowers corymbed or umbelled on a terminal 

 peduncle. (Name from x ^ a > winter, and 0tA.o>, to love, in allusion to one of 

 the popular names, viz., Wintergreen.)

 thers as in Pyrola, but conspicuously 2-horned. Style straight, exserted ; 

 stigma large, peltate, with 5 narrow and conspicuous radiating lobes. Valves 

 of the capsule naked. (Flowers occasionally tetrarnerous.) Scape 1 -flowered. 

 Otherwise as Pyrola ; intermediate between it and Chimaphila. (Name formed 

 of p6vos, single, and ^(m, delight, from the pretty solitary flower.) 



1. M. grandiflbra, Salisb. A small perennial, with the rounded and 

 veiny serrate thin leaves (6 - 9" long) clustered at the ascending apex of creep- 

 ing subterranean shoots ; the 1 - 2-bracted scape (2 - 4' high) bearing a white 

 or rose-colored terminal flower 6" wide. (M. uniflora, Gray.) Deep cold 

 woods, Labrador to Penn., Ind., Minn., and westward. June. (Eu.)

 what 2-horned base (by inversion the apparent apex) Style generally long; 

 etigma 5-lobed or 5-rayed. Capsule depressed-globose, 5-lobed, 5-celled, 5

 cellular-reticulated coat. Low and smooth perennial herbs, with running 

 subterranean shoots, bearing a cluster of rounded petioled evergreen root 

 leaves, and a simple raceme of nodding flowers, on an upright more or less 

 scaly-bracted scape. (Name a diminutive of Pyrus, the Pear-tree, from some 

 fancied resemblance in the foliage.) 



* Style straight, much narrower than the peltate 5-rayed stigma, petals and 

 stamens erect and connivent ; anthers not narrowed below the openings.
