According to Thad Howard in his book, Bulbs for Warm Climates, Rigidella is
a genus of bulbs from Mexico and Guatemala and are allied to Tigridia and can
be hybridized with T. pavonia. The flowers either open in the morning or
afternoon, closing at night. They are hummingbird pollinated, and thrive in
cultivation in zones 8-10 if summers are cool. They also do well in zones 5-7
if dug and stored in winter. They do not do well where summers are hot and
dry.

R. flammea grows on cliffs and ledges in the state of Michoacan in Mexico.
It's a robust species with flowers opening in the afternoon and closing at
sunset. Flowers are scarlet with the interior spotted purplish against a
yellow background. Leaves appear after flowering. It is a high-elevation plant
that needs cool alpine conditions.

Hope this helps.
