× Gasteraloe

×&thinsp;Gasteraloe (×&thinsp;Gastrolea) is a genus of hybrid plants, from mixtures of species from the Aloe or Aristaloe and Gasteria genera. Since most species in the genus originated as hybrids, the genus is sometimes called a "nothogenus".

Description
×&thinsp;Gasteraloe hybrids are typically stemless or almost stemless. Their succulent leaves, which are usually spotted or marked and have toothed margins, form rosettes.

Gonialoe variegata and Aristaloe aristata are especially commonly used for these hybrids, as they are far more amenable to hybridization with gasterias than most other "aloes".
