 the seeds were similar. The synonymy of this species is —

jEscuIus discolor, var. mollis, is now known to be common in the neighborhood of Home ami Augusta, Georgia, and nt Alabama 

 City, Talladega Springs, Birmingham, near Selma, and at Tarvers, Alabama. It is distributed therefore from northern Ccorgia 

 through central Alabama, and through Louisiana to the valley of the Guadalonpe River in Texas, and through Arkansas to south- 

 eastern Missouri and southwestern Tennessee. All the published references to .Fundus I'ana in the region west of the Missis- 

 sippi River probably refer to this plant or to sEsculus discolor, as JSsculus Pavia is not uow known to range west of Kentucky 

 and eastern Louisiana.

This plant is of considerable interest, as it is the only one of the Eupavia: with yellow flowers. It is very common on the slope 

 above the Comal Spring, where it is a shrub with erect stems, sometimes from 3 to 4 metres high, and appears to be confined to the 

 Edwards Plateau formation, on which it is usually the only form, although occasionally a plant of the red-flowered variety occurs 

 in the neighborhood of Boerne. It flowers a few days earlier than jEsculus discolor and its variety mollis, which are both common 

 just below it at Comal Springs. The pubescence on the under surface of the leaflets, the glands on the margins of the petals and 

 the color of the seeds are the same in these plants, and they can only be distinguished by the color of the flowers, which in 

 all the three forms vary in the width of the calyx. Growing here with JEsculus discolor and its variety mollis there are plants 

 with very beautiful rose-colored petals, which show the tendency of this species to vary in the color of the flowers.
