basal and cauline, cauline often reduced, basal often forming well-developed rosette, alternate; stipules absent; long-petiolate; blade often pinnately (rarely bipinnately) lobed, sometimes unlobed, or lateral lobes greatly reduced or absent, terminal lobe usually large, margins usually regularly or irregularly dentate to serrate, sometimes denticulate, serrulate, or entire, abaxial surface or margin with ± conspicuous, usually brown, oil cells. |

Discussion | Subspecies funerea is known from Eureka and Saline valleys, and the region of Death Valley, Inyo County, and northernmost San Bernardino County. It intergrades with subspp. aurantiaca and claviformis; sometimes it hybridizes with Chylismia brevipes subsp. brevipes and C. munzii.

Species 16 (16 in the flora). Chylismia is distinguished from other genera formerly included in Camissonia by straight to arcuate (never twisted or curled) capsules on distinct pedicels and seeds in 2 rows per locule. R. A. Levin et al. (2004) included only one species each from Camissonia sects. Chylismia and Lignothera; the two formed a moderately supported branch, which led W. L. Wagner et al. (2007) to recognize Chylismia as a distinct genus. Chylismia is strongly supported in a sister relationship to the realigned Oenothera. This clade is in turn sister to Eulobus. Reproductive features include: self-incompatible (C. brevipes, C. claviformis, C. multijuga, C. munzii, and probably C. confertiflora, C. eastwoodiae, and C. parryi; P. H. Raven 1962, 1969) or self-compatible; flowers diurnal, outcrossing and pollinated by mostly oligolectic bees or autogamous, or opening one to two hours before sunset (in one subspecies of C. claviformis and the two species of sect. Lignothera); the evening-opening subspecies of C. claviformis pollinated mostly by oligolectic bees and moths, C. cardiophylla mainly by small moths, and C. arenaria, with its long floral tubes, by hawkmoths (E. G. Linsley et al. 1963, 1963b, 1964). Most species are diploid (2n = 14) but there are occasional tetraploids (2n = 28); floating translocations are relatively common (Raven 1962, 1969).
