Abstract Introduction The flora of the lower Río Bavispe Valley from the Huásabas Although the Tropic of Cancer is located at 23.4°N, just north area south to the Río Áros at 430 to 1,510 m. elevations (1,410 of Mazatlán, , the northernmost tropical deciduous to 4,954 ft.) was studied from 1995 to 2016. A total of 401 forest occurs in the Sierra San Javier, Sonora (28.6°N), 680 taxa in 74 families and 274 genera were recorded in the km. (422 mi.) to the north-northwest (Van Devender et al. lower Río Bavispe Valley study area, including 24 non-native 2013a). The northernmost tropical vegetation in Sonora is (6.0%). The families with the most species were foothills thornscrub in the Ríos Bavispe and Sonora Valleys. (50), (50), (42), In this paper, we summarize the flora of foothills thornscrub (20), (19), Cactaceae (13), Solanaceae (15), and and adjacent desert in the lower Río Bavispe Valley (11), representing 54.9% of the flora. The genera south of Huásabas, Sonora. with the most species were Acacia (8), (7), Study Area and Methods (6), Quercus (6), Boerhavia (5), Muhlenbergia (5), and Opuntia (5). The Río Bavispe begins in the northernmost Sierra Madre Occidental near Mesa Tres Ríos on the border. The river flows from Huachinera northward, west around the 1 GreaterGood.org, 6262 N.

The latter date was on a Madrean Discovery the lower Río Bavispe Valley as part of various projects. In Expedition (MDE) Education trip for the purpose of giving a May 1995, plants were collected at Cruz del Diablo, a natural history presentation for the Secundaria Técnica (a spectacular overlook canyon east-northeast of Huásabas middle school) in Huásabas.

this iconic desert . Hibiscus acicularis is an interesting species that is widespread in the in northeastern Mexico. It is a small woody that resembles H. coulteri, except that the is canary yellow (Figure 7). Its presence in Sonora was only recognized in 1979 but it is presently known from 15 localities in Sonoran desertscrub and FTS. It is not yet known for Arizona. Riparian along the Río Bavispe include Populus fremontii, Salix bonplandiana, S. gooddingii, Platanus wrightii, Fraxinus velutina, and Juglans major. The latter has separate species. The two species are sympatric in Arroyo los Amenazada (Threatened) protection status in the Mexican Pavos on the Northern Jaguar Reserve.

Tropical riparian trees in the flora (Chihuahuan species known from three localities in Sonora), include Guazuma ulmifolia, Havardia mexicana, Sapindus Dalea tentaculoides (see above), Mabrya geniculata ( of saponaria, and Vitex mollis. Previously, S. saponaria was two species in Chihuahua and Sonora), and Metastelma thought to have varieties drummondii and saponaria.

O. puberula (small, brittle, spiny tropical siviri near its northern limits), and Yucca grandiflora (big tree yucca in Sonora and adjacent Chihuahua). The small Santa Cruz striped agave (A. parviflora) is a species of Special Concern in Arizona. The species has Amenazada (Threatened) protection status in the Mexican endangered species law (NOM 059 SEMARNAT 2010). There are three subspecies in Sonora: A. p. var. parviflora is in southern Arizona and adjacent Sonora. The A. p. ssp. flexiflora is endemic to eastern Sonora from the Mátape-Moctezuma area east to the Huásabas-Nácori Chico area. The A. p. ssp. densiflora in the Maycoba area in the Sierra Madre Occidental in eastern Sonora is a larger variety (Starr and Van Devender 2011). All are locally common and not in danger. The flora of foothills thornscrub is an important part of the flora of Sonora and the transition from the New World tropics to the north temperate
