Clematis Texensis Buckley, Proc. Phila. Acad. 448 (1861). 



Occurring sparingly along the Guadalupe and Town Creek, at Kerr- 

 ville. This plant agrees very well with Buckley's description, the 

 "caule scandente, foliis pedunculatis, integris, lato-ovatis, acuminatis 

 mucronatis," being quite correct, but the thin leaves are coriaceous, which 

 character is much more apparent in dried specimens than in fresh ones. 

 They are light green, glaucous beneath. " Part of these stem leaflets 

 are on long tendril-like petioles," corresponds also. The slender, conical 

 calyx is slightly contracted near the middle, an inch or more long, bright 

 scarlet in color, rarely reflexed at the tips and then only slightly. 



The figure in Bot. Mag. /. 6594, of C. coccinea Engelm. does not 

 agree with this plant, neither do specimens in the Columbia College 

 herbarium, cultivated at Easton, Pa. C. coccinea has much shorter and 

 broader flowers, thick, coriaceous, and rounder and more recticulated 

 leaflets. Distributed as C. " Texana" Buckley. A form intermediate 

 between this plant and C. Simsii was collected on the Guadalupe, in 

 close proximity to both. The leaflets are more coriaceous than those of 

 either of the others, glaucous, though less so than in C. Texensis. The 

 flower is dull purple red, or rather brick red, and in shape more like 

 that of C. Simsii. 



April 19 to June 26 (1608); type locality, "on the Colorado river, 

 above Austin."
