A fairly new species from Sierra de Niltepec, Zanatepec, Oaxaca, Mexico. A smallish grower 6 to 8 inches tall is a lithophyte or cliff dwelling species in nature. The leaves are stiff in an upright to slightly spreading rosette, silvery-gray and tapering to a point. The inflorescence is short to about 1.5 times the length of the leaves, well branched and light green with white flowers. Rare in collections.

This is the proliferating form of secunda from the area north of Quito, Ecuador. A large growing plant with silvery-green leaves in an upright rosette, which when in bloom produces its offsets on its inflorescence. The inflorescence is tall and branched, up to 3 feet or so, and usually bright red in color, and the adventitious offsets are produced at almost every internode. In nature it grows on the ground on rocky slopes in full sun. Popular with collectors, it is usually grown potted to gain size and vigor.
