 The habit, aestivation of the corolla, and character of the ovary 



and fruit leave no doubt that this genus should be classed with the 



Hcdyoüdeae. It is distinet as a genus in virtue of the relatively large 



size of the solitary axillary flowers, and of the very definitive invohicie 



Ol bract-like organs assoeiated with the calyx and fruit. The habit 



is much like that of one of the coarser Hedyotes; but the conspicuous 



scales alternating with the ealyx-lobe« distinguish this plant readily 



from that genus.
