|phenology=Flowering and fruiting mid Apr–mid Jun.

|distribution=Calif.;Oreg.
|discussion=<p>Variety robustior is known from the mountains of west-central California to interior southwestern Oregon (most known Oregon collections occurred before 1925). Like var. ambusticola, it tends to occur higher than var. acaulis where sympatric. Toward the south, it intergrades about equally with the other varieties (J. D. Morefield 1992c). The largest sizes described above are from a garden-grown specimen; field-collected plants from the same gathering were depauperate but otherwise typical. Variety robustior and Hesperevax sparsiflora var. brevifolia are superficially similar and have been confused; they are not known to intergrade or hybridize.</p>
