Il8 SAXIFRAGACEAE (SAXIFRAGE FAMILY) 



GORMANIA 



Low, SedmnAike, perennial by horizontal rootstocks. Leaves spatulate 

 to orbicular; stem leaves smaller. Flowers cymose or thyrsoid. Stamens 

 lo, on the corolla. Carpels many-seeded, united below, erect or nearly 

 so even in fruit. — (Honor of M. W. Gorman, an American botanist.) 



A. Corolla red or pink. U. G. laxa 



AA. Corolla yellow. 

 B. Corolla segments long-acuminate, much exceeding the filaments. W. C. E. 



G. oregana 

 BB. Corolla segments acute to acuminate, little longer than the filaments. 

 C. Leaves spatulate. E. G. watsoni 



CC. , Leaves orbicular. E. G. debills 



SEDUM (Stonecrop) 



Flowers clustered; clusters often i-sided^ Calyx 4-5-lobed or -parted. 

 Petals distinct or united at base, in ours yellow or purple. Stamens 8 or 

 10. Carpels distinct or united at the very base, few- to many-seeded. — 

 (L. sedere = to sit; because the basal tuft of leaves is often flat on the 

 rocks.) 



A. Leaves spatulate or obovate, widest above their middle, flat. 

 B. Flowers purple, dioecious; racemes not i-sided. C. E. S. integrifoliiun 



BB. Flowers yellow, perfect; racemes i-sided. 

 C. Follicles erect or nearly so; leaves with line of pits underneath near margin. 

 W. E. S. spathuUfolluin 



CC. Follicles widely spreading; leaves without a line of pits. 

 D. Leaves of sterile shoots opposite; cyme branches short, mostly simple. W. C.

DD. Leaves alternate; cyme branches long, forked. 



E. Biennial, 2.5 dm. or less high, not forming offsets. C. S. leibergU 



EE. Perennial, i dm. or less high, forming offsets. W. S. woodii 



AA. Leaves linear to ovate, widest at or below their middle, terete or flat. 

 F. Perennial; leaves linear to lanceolate. 

 G. Leaves linear, not ciliate; follicles erect or nearly so. W. C. E.

SAXIFRAGACEAE (Saxifrage Family) 



Herbs, but sometimes shrubby. Leaves opposite or alternate, 

 simple or compound, often palmately veined. Flowers mostly per- 

 fect. Sepals 4-5, united to nearly distinct. Petals o or 4 or 5, 

 alternate with the sepals. Stamens as many or twice as many as 

 the sepals, rarely fewer, on the calyx. Ovary superior or partly inferior,
