In south-eastern Arizona scattered mountain ranges rise above the arid lowlands which prevail across much of the southy-western United States. The forests and woodlands of the upper elevations of these ranges are islanded in deserts and desert grasslands, and form an archipelago of wooded ares in whcih mountain flores of the western United States and Mexico are variously combined into plant communities. One of these ranges, the Santa Catalina Mountains, has been subject to intensive study (Shreve 1915, Whittaker & Niering 1964, 1965; Niering Whittaker & Lowe 1963). This paper uses techniques of direct gradient analysis and floristic comparison to study the vegetation of limestone vs. acid parent materials, on the north side of the range.
