Dyschoriste schiedeana (Nees) Kuntze

PHENOLOGY.— Flowering: July–August; fruiting: July–August.

DISTRIBUTION.— Mexico (Ags., Coah., Dur., Gto., Hgo., N.L., Oax., Pue., Que., S.L.P., Tamps., Ver., Zac.).

HABITAT.— Thornscrub, oak forest, sometimes on limestone.

ELEVATION.— 700–2460 meters.

NOTES.— Plants of this species ( Fig. 2E ) from Tamaulipas were described and treated by Henrickson (1999) as pertaining to var. schiedeana (Coah., Hgo., N.L., Que., S.L.P., Tamps., Ver., Zac.) . Those cited below generally conform to his “ Type 3” form (Coah., N.L., Tamps.) of the variety with narrow, linear to linear-oblanceolate, and mostly conduplicate leaves. The morphological distinctions between this taxon and D. greenmanii are subtle at best. In general, plants treated as D. schiedeana are more conspicuously pubescent throughout than are those of D. greenmanii . Bartlett 10328 (F) from Cerro Tinaja near San José in the Sierra de San Carlos (850 meters) was annotated by Henrickson in 1999 as D. poliodes Leonard & Gentry var. poliodes . Henrickson (1999) did not cite this collection, and occurrences of the taxon were restricted to northern and central Nuevo León. With its flat and oblong to oblanceolate leaves, the identity of Bartlett 10328 remains undetermined, but it “keys” closest to D. schiedeana in our key to Tamaulipan Dyschoriste .
