This is a very good species, quite distinct from the Petalostemon 
violaceus, which has been made dumping ground of various red- 
flowered species which are not at all related to it. This species is 
much more closely related to Reverchoni than to purpurea. 
Coleman county, southeastern Texas.

ASPLENIUM BRADLEYI D.C. Eaton, Bull. Torr. Club, 6: 11. 187 3. 
Although not extending the known geographic area, King’s 
and Crowder’s mountains, N. C., furnish two more stations for this 
rare fern. I found it on the two isolated peaks just mentioned, in th 
summer of 1894; it grew both on the cliffs at the summits and in 
crevices on large boulders on the slopes and at the base of the 
mountains. The leaves varied from less than one decimeter to 
between two and three decimeters in length.

Mr. A. H. Curtiss informs me that this plant escaped from cul- 
tivation a few years ago and has now become a serious obstruc- | 
tion to navigation in the tributaries of the St. John’s river. It has _ 
established itself in other parts of Florida. 
Iris CAROLINIANA S. Wats. in A. Gray, Man. Ed. 6, 514. 1890. 
In the spring of 1893 great quantities of this lately described _ 
Iris were found east of the great Dismal Swamp in Virginia by _ 
Dr. Britton and myself. During the spring of 1894 Tracy and — 
Earle secured good fruiting specimens at Pointe du Chene, Lou- ae 
isiana (no. 2898), and last summer I found it very common in the - 
swamps about Macon, —— and oe the middle part» 
of that state.
