Revision as of 13:40, 27 July 2019
Leaf blade mostly 2-pinnate or 2-ternate; leaflets often deeply lobed, mostly 3-4 cm, somewhat leathery. Flowers: sepals mostly 2-4 × 1-3 cm; stamens with filaments and extended connectives usually usually glabrous, occasionally with a few hairs. 2n = 16.
Phenology: Flowering spring–fall (Apr–Sep).
Habitat: Rocky sites
Elevation: 1200-2300 m
Distribution
N.Mex., Tex., Mexico (Coahuila).
Discussion
In typical Clematis pitcheri var. dictyota, the stamen filaments and the extended anther connectives are glabrous or nearly so, whereas in typical C. pitcheri var. pitcheri they are pubescent. In some parts of the range of the species, however, these character states are not well correlated with leaflet size and thickness.
The names Clematis filifera Bentham and C. pitcheri var. filifera (Bentham) R.O. Erickson have generally been applied to this variety or to a taxon consisting in large part of this variety, but the type specimen is referable to C. pitcheri var. pitcheri (W. M. Dennis 1979).
