This plant is evidently most closely related to A. confertifoha 
(Torr.) Wats. from which it is at once distinguishable by the narrow 
fruiting bracts. The bracts of A. confertifolia are usually suborbi- 
cular. The specimen is very mature, nearly all the leaves having 
fallen, but apparently these are not crowded as in Torrey’s plant. 
The branches, too, are much more spiny.

In the N. A. Fl. xxi. 77 (1916) the place of publication of this 
species is given as “ Proc. Am. Acad. 9: 93. 1874.” This may be 
disposed of as a clerical error. But another error on the same page 
cannot be passed over so easily. This is the maintenance of 
K. vestita (Wats.) Rydb. as a species distinct from K. americana 
Wats. Even as reference to the volumes nine and seventeen of the 
“ Proceedings ”’ will verify the citations listed above so reference 
to material of K. americana will show that Watson knew what he 
was about when he treated the more pilose specimens as represent-_ 
ing only a variety. Doubtless, too, Watson was aware of the analo- 
gous variability displayed by the Old World species, K. prostrata. 
This plant varies from essentially glabrous to inordinately long- 
villous and though the extremes are much more pronounced than 
in the case of K. americana and the variety vestita, no one has con- 
sidered them other than as constituting one variable specific unit.

Apparently this unusual plant has never been properly chris- 
tened. I follow Bentham, Moquin, and Volkens in maintaining the 
genus Enchylaena distinct from Kochia. It is true, as noticed by 
Bentham and also by Volkens, that it is not very sharply defined 
but on the other hand its reduction to Kochia would necessitate, in 
the interests of consistency, the abandoning as well of the long- 
established genera Bassia and Chenolea. But in general these four 
genera are satisfactorily distinct and surely should be maintained.
