Discussion

Variety texanum can be distinguished from other members of the genus in most of its range by its yellow flowers, distinct styles, and conspicuously glandular-toothed inner sepals. Its capsules also tend to persist longer than those of L. striatum and L. virginianum, in which the capsules shatter early.
