Triteleia crocea
Triteleia ixioides
Plants of Triteleia crocea from the Trinity Mountains of northern California differ from others of the species in having pale blue perianths instead of yellow ones, with lobes slightly fringed toward the apex instead of entire. These plants first were assigned to a separate species, and subsequently have been transferred to this one, where clearly they belong. Formal recognition at subspecific rank may prove desirable in future.

Subspecies 5 (5 in the flora).
As defined by L. W. Lenz (1975, 1976b), Triteleia ixioides consists of five groups of plants that, although readily recognizable as a rule, often cannot be separated by constant characters. Subspecies ixioides and subsp. cookii are strictly coastal and widely separated geographically from the three subspecies of the interior. They flower from May to August (a month earlier than subsp. scabra) and usually are found in the shade of oaks, cypresses, or pines. Polyploidy is rampant and perhaps indicative of the geographical and ecological differentiation of these morphologically similar subspecies.
