Discussion

Of conservation concern.

Subspecies lyonii is known from Merced County.

Kruckeberg and Morrison described subsp. lyonii based on plants with an exclusively greenish yellow terminal cluster of sterile flowers, and discussed a sympatric form with greenish yellow sepals and a purple terminal cluster as a ‘bicolor’ form. Subsequent collections show that plants with only a greenish yellow terminal sterile cluster are absent in some years, and the ‘bicolor’ form is here included in subsp. lyonii.
