SUNFLOWER FAMILY 



(Composi tee) 



Herbs, shrubs, or even trees; flowers numerous in a dense 

 head on a common receptacle, which is the enlarged top of the 

 peduncle, and surrounded by a circle of bracts called the invol- 

 ucre. Corolla either tubular, or the limb prolonged into a 

 strap, toothed at the summit. In some cases both sorts of 

 flowers are present in the head the tubular occupying the 

 centre and called "disk flowers," the strap-shaped occupying 

 the margin and called "ray. flowers." Calyx tube united 

 with the seed-vessels (achenes), often continued into a ring of 

 bristles, hairs, or scales known collectively as a "pappus." 



ENCELIA (Encelia californica, Nutt.). Flower heads showy 

 with golden-yellow rays and brownish-purple disks, solitary 

 on long, naked peduncles. Leaves short petioled, mostly 

 alternate, broadly lance-shaped, about 2 inches long, green 

 both sides and prominently 3-nerved from the base. A bushy 

 perennial common on dry hillsides, Southern California east- 

 ward to Arizona, blooming more or less at all seasons. A 

 showy sunflower-like blossom.
