116 NATURAL HISTORY OF PLANTS. 
leaves are alternate, simple, entire or two-lobed, with membranous 
or scaly caducous lateral stipules. The flowers form short, simple 
or compound racemes (fig. 87), inserted on the branches, or on 
rugose prominences from the boughs and trunk.’ 
VI. CASSIA SERIES. 
Cassia? (Fr., Casse; figs. 92-105) has irregular hermaphrodite 
flowers. The receptacle is slightly convex or flat on top, or even 
Cassia floribunda.

slightly concave. The calyx consists of five sepals, nearly always 
unequal and quincuncially imbricated in the bud. As the flower is 
resupinate, one is anterior; this is sepal 1, which is the smallest of 
all, as may be seen in any of these species of Cassia which are 
commonly cultivated in our flower gardens, especially C. floribunda® 
1 These prominences correspond to old leaf 
axils. These, as in numerous generations of 
inflorescences, follow each other every year; and 
their axes, which remain very short, are gradually 
confounded into a more or less prominent mass. 
Thus we have to do with successive series of 
inflorescences occupying the same seat.
