Page 41. Table 2, gives 79 non-native species; the correct number is 88: 54 Dicotyledons and 34 Monocotyledons (p. 33 and Appendix D, p. 604).

Selaginellaceae: Habit drawing represents S. eremophila. (A) S. arizonica; (B) S. eremophila. The illustrations represent dorsal (adaxial) surfaces of leaves. The larger leaves (1) are from the undersides of stems, the smaller leaves (2) are from the uppersides of stems.

Page 74. Rhus aromatica. The variety in the flora area best conforms to var. trilobata (Nuttall) A. Gray [R. trilobata Nuttall ex Torrey & A. Gray]. Western North America from Alberta to Iowa to northern Mexico.

Page 85. Add to the flora: Matelea parvifolia (Torrey) Woodson. Small perennial vines. Leaves more or less arrow-shaped. Flowers olive green to brown-purple; fruits elongated with a few blunt tubercles. Found at the northeastern margin of the flora area. Vining in shrubs along washes and small arroyos in the Sierra Cipriano southwest of Sonoyta; more common in nearby Arizona. Mojave Desert in California and southern Nevada to Texas, Baja California and Sonora.

10 km SW of Sonoyta on Mex Hwy 8, locally common, F 88-172.

Page 203. Illustration for Opuntia ramosissima is a repeat of O. fulgida (see page 4).

Page 215-223. Opuntia. There is strong evidence for more natural generic definitions in the subfamily Opuntioideae. In this regard, Opuntia sensu lato in western North America is treated as three rather well-defined genera: Cylindropuntia, Grusonia (Corynopuntia), and Opuntia. References: E. F. Anderson. 2001.

Page 369. Boerhavia caribaea Jacquin. Since publication of the Gran Desierto Flora, Richard Spellenberg (personal communication, 2001) has concluded that B. caribaea and B. diffusa are distinct species. Thus B. caribaea is the species in the Gran Desierto and elsewhere in the Sonoran Desert.

Page 373. Mirabilis laevis (Bentham) Curran var. villosa (Kellogg) Spellenberg [M. bigelovii A. Gray]. Spellenberg's interpretation of this species includes three varieties, ranging from eastern Oregon and southwestern Utah to northern Baja California Sur and northwestern Sonora; he maps var. villosa from southern Nevada and southwestern Utah to Baja California and northwestern Sonora.

Following the work of Hunziker, Philip Jenkins (personal communication 2002), in his studies for the Flora of North America project, found no reason to segregate Calibrachoa from Petunia.
