 the pretty solitary flower.)

 serrate thin leaves, 1-3 cm. long, clustered at the ascending apex of creeping 

 subterranean shoots; the 1-2-bracted scape, 3-13 cm. high, bearing a fragrant

 deciduous. Stamens 10 ; filaments naked ; anthers extrorse in the bud, but in 

 the flower inverted by the inflexion of the apex of the filament, more or less 

 4-celled, opening by a pair of pores at the blunt or somewhat 2-horned base 

 (by inversion the apparent apex). Stigma o-lobed or 5-rayed. Capsule de- 

 pressed-globose, 5-lobed, 5-valved from the base upward (loculicidal). Seeds 

 minute, innumerable, resembling sawdust, with a very loose cellular-reticulated 

 coat. Low and smooth perennial herbs, with running subterranean shoots, 

 bearing a cluster of roundish petioled evergreen basal 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.)
