[oregonflora.org] Description, Habitat: Synonym Cryptantha intermedia var. johnstonii Fruits 1 to 2(4), solitary nutlet, if present, po­sitioned toward inflorescence axis, ovate to lance-ovate, 2.2 to 2.5 mm, brown to dark grayish, bases truncate to rounded, tips acute, surfaces dull or shiny, low-rounded tuberculate, usually densely papillate, papillae rarely absent, adaxial surfaces attachment scar edges not raised, usually abutted entire length, widely bifid-forked, but usually not gapped at base. Gravelly, basalt, clay, or serpentine soil, chaparral, grasslands, slopes, open woodlands. Flowering May to Jul. 0 to 2500 m. BR, Casc, Col, CR, ECas, Lava, Sisk, WV. CA, ID, WA. Native. Variety hendersonii is interpreted as the northern phase of Cryptantha intermedia, with generally fewer nutlets per flower (typically one or two), surfaces usually densely papillate and scattered low-tuberculate, and the attachment scar usually abutted the entire length. The geographic boundary between C. i. var. hendersonii and var. intermedia is ill-defined. The former might warrant species recognition. (contributed by Mary Ann Machi)
