Univ. Calif. Publ. Bot. 20: 359. 1955.

Basionym: Eucharidium Fischer & C. A. Meyer Index Seminum (St. Petersburg) 2: 36. 1836
Synonyms: Clarkia subg. Eucharidium (Fischer & C. A. Meyer) Jepson
Treatment appears in FNA Volume 10.

Inflorescences: axis suberect or slightly recurved; buds pendent. Flowers: floral-tube narrowly tubular, 13–35 mm; sepals reflexed together to 1 side; petals pink, sometimes white-streaked, fan-shaped, conspicuously 3-lobed, middle lobe often longer than laterals, claw slender, not lobed; stamens 4. Capsules subterete; sessile or subsessile.

Discussion

Species 2 (2 in the flora).

Section Eucharidium includes two species characterized by large tri-lobed petals, four rather than eight stamens, and a long floral tube that adapts them to pollination by long-tongued Lepidoptera or Diptera (G. A. Allen et al. 1990).
