Apparently confined to central Florida. It is close to K. car- 
nea, but seems to be distinct.

KUHNISTERA GATTINGERI n. sp. 
Perennial, stems a foot in length or more, usually branching 
from the base, sometimes decumbent, sparingly glandular and. 
pubescent, sometimes villous on the peduncles; leaflets two or 
three pairs, narrowly linear or oblong, one-half to three-fourths of 
an inch long, one line in width or less, dull and glandular on the 
upper side, light green beneath, the mid-vein prominent; spikes on 
rather short peduncles, cylindrical, loose, especially when old, one 
inch to two and a half incheslong; bracts slightly longer than the 
calyx, oval-lanceolate, slender-pointed, glandular, pubescent; calyx 
pubescent with spreading hairs, the lanceolate lobes slightly shorter 
than the tube and more pubescent; petals deep rose-purple ; ovary 
and base of style pubescent. 
This plant has been distributed as Petalostemon decumbens 
Nutt., but Nuttall’s type, collected «on the plains of the Red 
River,” is preserved in the herbarium of Columbia University, and 
is a very different species. I take pleasure in dedicating it to Dr. 
A. Gattinger, who first collected it about Nashville and Lavergne, 
Tenn. Some of his specimens are in Curtiss’ North American 
Plants, no. 565. Dr. Chas. Mohr has also collected it at Russel- 
ville, Ala., a form with somewhat laxer inflorescence, and more 
pubescent calyx.

A species of the gulf coast extending from Florida to Lou- 
isiana. The majority of the plants which are in herbaria labeled 
Petalostemon gracile belong to KX. oligophylla. True gracilis has 
not been found outside of the range given. Pe.
