cent utricle. The spreading bracts and withering stigmas 
render the utricles somewhat conspicuous when old. This 
probably accounts for one of the:characters on which Dr. Wat- 
son based his var. subuuda. Those forms of Watson’s var. 
subnuda with clustered inflorescence belong naturally with the 
following variety. —Most abundant in the north central states 
east and west of the Mississippi, but extending as far as Man- 
itoba at the north, Vermont at the east, Tennessee at the 
south and western Nebraska at the west. With the exception 
of ballast specimens from New Jersey no Atlantic coast spec- 
imens were seen.

Somewhat weaker, often decumbent, with rather large 
flowers in isolated glomerules. Though there are occasional 
transition forms between this and the above, the mass of them 
seems to form a natural group, which may very conveniently 
be set apart.—Range as in the above variety. The locality 
and the aggregate inflorescence point to the probable identity 
of this with Moquin-Tandon’s variety, though in one specimen 
of Acnida cannabina, collected in Massachusetts, the same 
aggregated tendency was seen. 
“A. TAMARISCINA prostrata, var. nov. 
Prostrate and diffusely spreading after the manner of Amar- 
anthus crispus, though sometimes ascending as in Amaran- 
thus deflexus: leaves small, spatulate: inflorescence crowded 
in axillary clusters and sometimes in minute glomerules, leafy. 
—Michigan to Dakota, extending as far south as Missoutl.

GOMPHRENA L. Sp. Pl. 224. 1753. 
Hirsute or villous herbs, erect, decumbent or prostrate, with 
usually swollen nodes, sessile or short petioled entire leaves, 
mostly solitary but sometimes clustered heads, which are 
usually sessile, though sometimes peduncled, perfect flowers, 
5-parted calyx often villous at base, and stamen tube 5-cleft 
with emarginate or 2-cleft lobes, ovules with long strap-shaped 
funiculus.
