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

|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 <i></i>var.<i> ambusticola</i>, it tends to occur higher than <i></i>var.<i> acaulis</i> 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 <i>Hesperevax sparsiflora </i>var.<i> brevifolia</i> are superficially similar and have been confused; they are not known to intergrade or hybridize.</p>
