 into petiole, cordate to subcordate at base, dentate to entire; scape 1-3.5 dm. tall; 

 umbel 1- to 6-flowered; bracts to 8 mm. long, lanceolate to oblanceolate, acute to

 tube 2-3 mm. long; calyx lobes 2.5-4 mm. long, triangular to lanceolate, acute 

 to acuminate; corolla tube maroon, yellow above, the white lobes 8-15 mm. long; 

 filaments less than 1 mm. long, free or slightly united; anthers 6.5-8 mm. long, 

 lanceolate to subulate, acute to acuminate, the pollen sacs yellow or reddish- 

 spotted; connective dark maroon to black above, yellow below, smooth (often 

 longitudinally wrinkled upon drying); stigma not enlarged; capsule 9-12 mm. 

 long, 4-5 mm. thick, cylindric, the thin wall valvate. D. Ellisiae Standi.

4. Androsace L. Rock-jasmine 



Small annual herbs with clustered radical leaves and very small flowers in an 

 umbel terminating a scape; calyx 5-cleft, the obconic tube short; corolla salverform 

 or funnelform, the somewhat inflated tube shorter than the calyx, constricted at 

 the throat, the limb 5-parted; capsule longitudinally 5-valved, enclosed in the 

 persistent calyx. 



About 100 species in cooler parts of the North Temperate Zone. 



1. Calyx lobes linear-elliptic to triangular-lanceolate, equal to or longer than the 



tube; involucral bracts broadly elliptic-obovate to oblanceolate 



1. A. occidentalis. 



1. Calyx lobes deltoid to acerose, much shorter than the tube; involucral bracts 

 narrowly lanceolate to subulate 2. A. septentrionalis. 



1. Androsace occidentalis Pursh. 



Dwarf plants to 7 cm. tall, usually much smaller; rosette leaves typically elliptic- 

 oblanceolate, to 2 cm. long and 6 mm. wide, entire or somewhat coarsely dentate 

 above middle, white-pubescent above with mostly simple hairs; scapes one to many, 

 erect or recurved-ascending, more or less equal in length, scabrous with stellate 

 hairs; involucral bracts elliptic-obovate to oblanceolate, to 6 mm. long; pedicels
