Discussion
Of conservation concern.
Heliomeris soliceps is characterized by the relatively long, scapiform peduncles rising beyond relatively short, leafy stems, and ovate to rhombic-ovate leaf blades that are relatively broader than those of most other members of the genus. Its blooming period is also significantly earlier than those of other members of Heliomeris. It is known from southern Utah, where it forms large populations.
