Two new species of Aloe: from the Kingdom of Saudi Arabia

摘要

The Kingdom of Saudi Arabia, situated in western Asia, is the largest country in the Arabian Peninsula, and is the home of many mysteries. Travel to and in the Kingdom has remained one of the most difficult in the world to arrange, due to it being basically closed off to outsiders other than those invited for some specific reason such as work, religious pilgrimage to the Islamic holy cities of Mecca and Medina, or other official reasons. This has led to a limited amount of exploration, research and discovery in many domains of natural history.
