KEY TO THE SPECIES. 



Ilowers axillary. 



Leaves flat, not crowded; seeds conspicuously costate. 

 Petals yellow; leaves linear; stems suffrutescent at

nearly so; pedicels stout, much shorter than the 



sepals 



Petals about 15 mm. long; leaves longer, 12 to 20 mm., 

 slender; sepals acute; pedicels slender, equaling
