Small montane or alpine herbs, with rosulate radical leaves and few 

 tp several scapes bearing aninvoiucrate umbel of small white or pink-

 (Androsakes, Greek name of a now unknown sea-plant.)

 equivalent of this. 



U. DODECATHEON L. Shootino Star. 

 Low perennial herbs of late spring, with radical leaves and a naked 

 scape bearing an umbel of few or many flowers. Corolla 5-parted, 

 with very short tube and dilated thickened throat, the long and 

 narrow divisions reflexed in flower (as also the calyx-lobes). Stamens 

 on the throat of the corolla; filaments short and flat, monadelphous, 

 but at length separable above. Stjie filiform, exserted. Fruit a 

 capsule with columnar placenta, surrounded at base by the now erect 

 calyx. (Greek dodeka, 12, and theos, god, the Primrose being under 

 the care of the deities. Singularly handsome flowers similar to those 

 of the cultivated Cyclanien. An American genus of 19 species 

 according to some authors; by others regarded as consisting of a 

 single polymorphic species. For our region we think it expedient to 

 recognize those given below. )

 Scapes red or reddish, 9 to 14 in. high, from a strong cluster of fleshy- 

 fibrous roots; leaves elliptic, often widest below the middle, the
