A nocturnal bloomer on open, grassy, undulating plain in basin below eastern Madrean escarpment, among diverse grasses and forbs on coarse volcanic alluvium. SYN Gaura mutabilis
An interesting path to name this taxon. Fairly easy to get to Chylismia (part guess, part no other genera quite fit.) claviformis as species okay but subspecies more problematic. Originally had guessed either claviformis or aurantiaca but each had issues. Decided on funerea because of 1) location, 2)petals white fading purple, 3) sepal tips in bud free and conspicuous, 4) plant generally strigose. The only thing not fitting is 'lateral leaflets generally 0'. This could indicate that, per the description in Jepson eflora 'Intergrades with Chylismia claviformis subsp. aurantiaca, Chylismia claviformis subsp. claviformis; occasionally hybridizes with Chylismia munzii, Chylismia brevipes subsp. brevipes.'
