STANDLEY—ALLIONIACEAE OF THE UNITED STATES. 325 
fragrans, Typ.” by Doctor Heimerl, but the specimen is without fruit, which 
would have distinguished it at once. 
Other specimens eramined: 
New Mexico: Coolidge, 1889, Munson & Mopkins; Chama River, 1904, 
Wooton 2827; Santa Fe, 1899, Cockerell. 
The following specimens from farther south should probably be referred 
here. They do not altogether agree with -1. fendleri and may possibly form 
a distinct species; they are certainly not .1. fragrans, The plants are more 
erect, less branched, and less spreading than the Santa Fe plant, besides differ- 
ing in several other particulars. 
New Mexico: Mesilla, Valley, 1893, Wooton; Tortugas Mountain near Las 
Cruces, 1900, Cockerell; Mexican Boundary Survey 1121; Jornado del 
Muerto, 1846, Wislizenus 81.

41. Abronia fragrans Nutt.; Hook. Kew Journ, Bot. 5: 2617, 18538, FIGURE 65. 
Perennial, erect: stems more or less puberulent 
throughout, rather stout; leaf blades ovate or elliptical, 
rounded or narrowed at the base, mostly obtuse or 
acutish at the apex, minutely puberulent and rough- 
ened on both surfaces or glabrous above: bracts ovate 
or broadly elliptical, acute or attenuate, 10 to 15 mm. 
long and about 8 mm, wide; flowers 2 cm. long or more, 
greenish-white; fruit 6 mm. long and 4 mm. wide or 
often larger, usually distinctly biturbinate, the outer 
ones strongly so and often irregular ; fruit not winged, but with low, thickened 
ridges which are strongly veined. 
The plants included here are, as a whole, remarkably uniform, although a 
few variant forms will be found. A form of the species which extends into 
western Kansas differs considerably in general appearance, but I have been 
unable to separate it. A plant from Oklahoma is reported to have red flowers, 
but otherwise it does not seem remarkable.
