the uenus DlpJacus Nutt. w:is t'ouiitlod. Jlt-ru the two jihicfiita; are 

 hardly at all united in the axis, even in the blossom ; which is olher- 

 wise that of a true Mimiilns. Then there is a low annual species with 

 short corolla and thin-walleil capsule, but the placenta' dividinj; with 

 the valves, which is so peculiar in wanting the angles or kcds which 

 are so conspicuous in Jlinndus that it was referred to a jjcculiar sec- 

 tion of Herpestis. Altogether it seems necessary to regard the whole 

 as one polymorphous genus, and to arrange our species as in the 

 subjoined conspectus.*

 well tbat Lindley's name takes precedence, as tliere was a mistake in supposing 

 that tins species was in Coulter's collection.

 stigma is sometimes of two very unequal lobes, as described by Bentbani, some- 

 times of two broad and rounded unequal lobes, sometimes peltate and nearly 

 circular, as in most of the following.
