Eustoma Salisb. (1806)
Etymology: Eustoma is named
after the Greek words eu- (beautiful, good, well-), and stoma
(mouth). The meaning of Eustoma is "good-tasting" or "well-spoken"
[Corneliuson, 1997], but in the case if this plant genus it might refer to
the distinct color patterns in the corolla mouth, hence 'beautiful mouth'.
Southern United States, Mexico, and the
areas, grassland, and pine forests often in dry environments.
Glabrous herbs with a bluish tone on their leaves and stems (glaucous).
Large, long-stemmed flowers in cymes, often only a few open at the time.
Sepals only fused close to the base and much smaller than petals.
Petals purple or bluish, large and rounded, only fused at base and forming
a trumpet or funnel-shaped corolla, and often with yellow on the inside
close to the mouth of the flowers. Stamens inserted close to the
base of the petals, and with long, only slightly twisted anthers. Stigma
