xeric

xeric \ZEER-ik\, adjective:

of, pertaining to, or adapted to a dry environment.

Tegene pointed out the subtle contouring that gradually ascended toward xeric slopes, where Lynden's army planted many surprises amidst the dry vegetation.

-- Robert Luis Rabello, The Long Journey

The range of plants selected tolerate this xeric, or very dry, regimen quite well.

-- Steven L. Cantor, Green Roofs in Sustainable Landscape Design

Xeric, a relatively young word, was coined by ecologists W.S. Cooper and A.O. Weese in 1926 to replace the word xerophytic for a lack of moisture in both plants and animals.
