A. Nels. The latter is said, by those who know it in the field, to 
differ strikingly in its. prostrate habit, but in the herbarium no 
technical differences are discoverable, and the habital differences, 
of course, are not then apparent. 
DONDIA MEXICANA Standley, N. Amer. Fl. 21: 89. 1916 
Most closely related to D. linearis (Ell.) Heller, a coastal plant 
of the West Indies and the eastern and southern United States, 
being distinguished chiefly by the much smaller seed. The fol- 
lowing are the only collections known at present:

The synonyms cited above are only the more important ones 
based upon North American plants. The most common Dondia 
of the western United States, northern Mexico, the Bahamas 
and Cuba, the writer is wholly unable to distinguish from the Old 
World D. fruticosa. The West Indian plant seems quite the same 
as that of the western United States, and the wide distribution in 
North America seems to make more plausible the specific identity 
of the Old World and American plants. 
The name D. Moquini, which has been much used in recent 
years, is a hyponym, as published by Torrey, for no adequate de- 
scription was given. Strictly interpreted, the name should be 
typified by a Cuban specimen cited by Moquin, to which Torrey 
referred. 
DONDIA RAMOSISSIMA Standley, N. Amer. Fl. 21: 91. 1916. 
The plants segregated under thisname have usually passed as D. 
suffrutescens (S.Wats.) Heller, a species ranging from western Texas
