SENNA FAMILY. Cassiaceae. 



There are many kinds of Cytisus, natives of Europe, 

 Asia, and Africa, named for Cythrus, one of the Cyclades, 

 where the first species was found. 



A handsome branching shrub, about 

 Scotch Broom 



Cytisus " ve * eet m S n Wlt h a l mos t smooth or 



scopdrius quite hairy leaves, with three, toothless 



Yellow leaflets, and fine clusters of flowers, each 



|^ g ' et S " mmer an inch or more long, with a yellow two- 

 ezcept Ariz. lipped calyx and a golden-yellow corolla, 



deeper in color at the base of the standard 

 and at the tips of the wings; the stamens ten, in one set; the 

 style curved in. The pod is flat, smooth on the sides, but 

 hairy along the edges, one or two inches long and curling 

 when ripe. This is said to have been brought to California 

 by Cornish miners. 



SENNA FAMILY. Cassiaceae. 



A large family, most of them tropical; trees, shrubs, and 

 herbs, with flowers more or less irregular in form, but not 

 like the flowers of the true Pea, though sometimes re- 

 sembling them ; calyx usually with five sepals ; corolla with 

 five petals, overlapping in the bud, the petal which corre- 

 sponds to the standard folded within the two side petals, 

 instead of covering them, as in the Pea flower; stamens, 

 ten, or fewer, in number, usually not united; ovar superior; 

 fruit a pod, mostly splitting into two halves, containing 

 one to many seeds. To this family belong the handsome 

 Red-bud, or Judas Tree, of our woodlands, both East and 

 West; the spiny Honey-locust; the Kentucky Coffee-tree, 

 with its fine foliage, of the central and eastern states; the 

 interesting Palo Verde, with greatly reduced leaves, of the 

 Southwest, and the fine Bird-of -paradise flowers, of 

 the tropics and Mexico, one or two of which are just begin- 

 ning to grow wild in southern Arizona and California. 



There are many kinds of Cassia, abundant in tropical 

 America; herbs, shrubs, or trees; leaflets even in number; 

 flowers usually yellow; calyx-teeth nearly equal; corolla 

 almost regular, with five, nearly equal, spreading petals, 

 with claws; stamens usually ten, sometimes five, often 

 unequal, some of the anthers often imperfect, or lacking; 

 pod flat or cylindrical, often curved, sometimes with 

 partitions between the numerous seeds.
