Aloe abyssicola

A large Yemeni aloe known only from the cliffs of Jabal al Arays in southern Yemen at about 900 m, where its rosettes of up to 50 grey-green leaves, each up to 50 cm long with blunt black teeth, hang upside down from vertical rock faces. In cultivation the leaves and branched, down-curving inflorescences grow upwards at first, but older plants often become pendant. It is listed on CITES Appendix II.
