Missourl: Wayne, 1900, Bush S25 (this is cited by Doctor Rydberg as A. 
bracteata, but it does not seem to be that species, for its leaves are 
much narrower and thicker and the aspect of the plant is very different).

Mr. K. K. Mackenzie writes me that 1. bushii Britton, which he has seen in 
its type locality, Jackson County. Missouri, is an artificial form of 1. linearis, 
which grows rather commonly along the railroad tracks. When this is cut down 
by the section men small, depauperate shoots spring up from the stubs that are 
Jeft, and one of these was described as A. bushii, 
The following collections could be referred here, if anyone cares to maintain 
this form as a variety: 
Missouri: Jackson County, 1893, Bush.

cock 421a; Tribune, 1802, Minnie Reed,

da. Allionia linearis subhispida (Heimerl) Standley. 
Mirabilis linearis subhispida Heimer], Ann. Cons. et Jard. Genev, 5:186. 1901. 
This is distinguished from the species by its stem which is more or less 
hirsute throughout, the pubescence extending to the leaves. It seems to be a 
smaller plant, too, and is probably a good species, but the author has seen no 
very good material. 
Specimens eramined: 
New Mexico: Capitan Mountains, 1900, Marle 883, type collection: south of 
San Rafael, 1906, Wooton; Atarque, 1906, Wooton; Gray, 1898, Skehan 
100; Magdalena, 1897, Herrick 65s. 
G. Allionia divaricata Rydb. Bull. Torr. Club 29: 691. 1902, 
From A. /inearis this is distinguished chiefly by its long, thin, acuminate 
leaves, which are also wider, and by the prominent petioles: from A. diffusa by 
the less pubescent peduncles, taller and less branched stem, and the petioled 
leaves; from A. glandulifera by its less branched habit, narrower and petioled 
leaves, and Jess abundant and different pubescence. The species is also more 
or less closely related to A. melanotricha. :
