1. MEADIA, Catesby. Herbs with tufted simple radical leaves, and 

 a naked scape, from a short perennial often bulbilliferous crown; the 

 roots fleshy-fibrous. Flowers 5-merous (rarely 4-merous or 6-merous), 

 umbellate, nodding. Calyx 5-parted, reflexed. Corolla very deeply 

 cleft, the purplish segments reflexed. Stamens with very short filaments, 

 often connate at base, inserted on the very short tube of the corolla; 

 anthers long, erect, mostly connivent around the style. Capsule oblong, 

 many-sided, in our species circumscissile near the summit. 



1. M. Hendersonii (Gray), O. Ktze. Leaves ovoid or obovoid, very 

 obtuse to almost truncate and retuse, entire, 2 in. long or more exclusive 

 of the equally long or longer broad petiole; herbage glabrous: scape 

 8 12 in. high: segments of corolla of a rich rose-purple, the short tube 

 dark maroon encircled by a band of light yellow: anthers about 2 lines 

 long, neither connivent nor divergent but erect: capsule oblong, twice 

 the length of the calyx, circumscissile well below the summit. Var. 

 cruciata (Greene). Leaves narrower; scapes taller and more slender: 

 flowers of a darker purple, always 4-merous: the anthers longer and 

 narrower. The type is common among the higher hills of both ranges 

 of coast mountains; the very marked variety on northward slopes of hills 

 about the Bay. Feb. April.
