A floristic and natural history account is provided for six eudicot families as part of the vascular plant flora of the contiguous protected areas of Organ Pipe Cactus National Monument, Cabeza Prieta National Wildlife Refuge, and the Tinajas Altas Region in southwestern Arizona. This portion of the flora includes Malpighiaceae, Malvaceae, Martynia...

... Abutilon abutiloides, A. berlandieri and A. californicum can be difficult to distinguish and are presumed to be closely related species. Their ranges and characteristics are discussed by Fryxell (1988), Fryxell and Hill (2015a), and Felger et al. (2015). Abutilon abutiloides is the most widespread of the three taxa and treated here as the only one of the three known to occur in Arizona, following Fryxell and Hill (2015a) and Felger et al. (2015). ...

The illustrated species are Abutilon abutiloides, Abutilon incanum, Abutilon malacum, Abutilon mollicomum, Abutilon palmeri, Abutilon parishii, Abutilon parvulum, Abutilon reventum, Abutilon theophrasti, Abutilon wrightii, Anoda abutiloides, Herissantia crispa, Malvastrum bicuspidatum, Pseudabutilon thurberi, Rhynchosida physocalyx, Sida abutilifolia, and Sida glabra.

Cañón del Nacapule cuts into the southeastern ank of the Sierra El Aguaje, a rugged volcanic range about 20 kilometers northwest of Guaymas. Nacapule is included in the Sonoran segment of the Gulf Coast subdivision of the Sonoran Desert. e bi-seasonal (summer and winter) rainfall is highly variable. Many plants of tropical origin reach their northern limits in this region or do not extend farther north in the arid coastal desert of western Sonora. e vegetation in the canyon resembles tropical thornscrub and ap- proaches the character of tropical deciduous forest in the wetter and shaded habitats, while the steep canyon walls and exposed habitats support desertscrub. e Nacapule ora includes 310 species in 233 genera and 72 families. e most diverse families are Fabaceae, Asteraceae, Poaceae, Malvaceae, Euphorbiaceae, and Cactaceae. Brief species accounts and identi cation keys as well as over 300 color photos are provided for the ora known from the canyon, nearby Nacapule Spring, and within 500 meters of the canyon mouth. Verbesina felgeri is endemic to the Sierra El Aguaje, and geographically isolated populations of tropical genera such as Aphanosperma, Briquetia, Coccoloba, and Ficus occur in the canyon. Plants not native to the Guaymas region, mostly Old World weeds, are represented by 19 species, three of which are not established as reproducing populations, including Corchorus olitorius, a new record for the state of Sonora. e canyon is managed for ecotourism by the local property owners, restoring earlier habitat degradation. Cañón del Nacapule, with 291 native species, provides conservation for 42% of the total native ora (ca. 700 taxa) of the 532,000 hectares (5320 km2) of the greater Guaymas region.
