Indigo Bush 563 



generic name Dalea, published for these plants by Ortega in 1800, is preceded 

 by Dalea of Gartner, published for a different genus in 1788. 



The Parosela arborescens (Torrey) Heller, was originally described as a small 

 tree from the San Fernando Mountains in southern California, but has not since 

 been met with as such. It differs from the above in being less spiny, having 

 more numerous hoary leaflets and close, spike-like inflorescence. 



Coral bean, Erythrina arborea (Chapman) Small, a shrub or woody herb, with armed stems, 

 sometimes 6 meters high, occurs in sandy soil in southern peninsular Florida and on the Keys. 

 Its leaves are 3-foliolate, the leaflets deltoid or hastately 3-lobed, 3.5 to 10 cm. -long, their rachis 

 and petioles wiry; flowers scarlet, 3 to 4 cm. long, in racemes up to 2 dm. long; the pods 

 are 8 to 12 cm. long and constricted between the scarlet seeds. By some this plant is con- 

 sidered to be a form or variety of the herbaceous Erythrina herbacea Linnaeus, which ranges 

 further northward, from North Carolina to Florida and Texas; and it cannot, with certainty, 

 be regarded as a tree.
