Derivation. From decuma, a tenth ; in reference to the prevailing number, in some of the parts
of fructification, being ten. In DeCandolle’s description of the genus, it is stated that the teeth
and nerves of the calyx, the petals, the stigmas, and the cells of the capsule, are each usually ten.
Gen. Char. Caly:

to the teeth of the calyx, and alternating with them. Sta-
tube campanulate; limb 7— 10-toothed,
