Nidularium innocentii var. lineatum (Mez) L.B.Sm.[as Nidularium innocentii var. lineatum (Mez) L. B. Sm.,]

Observations: —DISCUSSION
The variety lineatum differs from the other varieties in its variegated leaves with white or yellowish lines.This trait is seen occasionally in the wild, as in specimen Leme 23-B, but it apparently reproduces only vegetatively, not sexually. Although this case is an exception to the method used here, I decided to maintain the validity of this variety due to its huge popularity as an ornamental and to the fact that it is already widely cultivated and has been for almost 90 years.
