Aloe abyssicola

Aloe abyssicola was described by John Jacob Lavranos and A. S. Bilaidi in a 1971 issue of the Cactus and Succulent Journal. The specific epithet abyssicola is derived from the Latin terms , meaning "abyss", and , meaning "dwelling", in reference to the inaccessibility of the type locality. ==Distribution and habitat==

Aloe abyssicola is known only from the type locality, on the cliffs of Jabal al Arays in southern Yemen, approximately above sea level. It grows upside-down, hanging from the vertical cliff faces. ==Description==

Aloe abyssicola is a short-stemmed or stemless Aloe that grows upside-down in its natural habitat. The rosette is composed of up to 50 grey-green leaves, each measuring long and wide. The leaves are edged with blunt, black marginal teeth spaced approximately apart. The long inflorescence grows downwards and splits into 5 to 6 short, loosely packed racemoid branches that curve upward at the tips. The flowers are yellow-green in colour and measure long. ==References==
