‘A. CANNABINA AUSTRALIS (Gray). 
A. australis Gray (in part), Am. Nat. 10: 489. 1876. 
Plant and leaves larger: bracts various, sometimes almost 
as long as the flower: utricle ovate, smaller than in the 
species: stigmas divaricate: spikes naked, long, slender and 
paniculate.—Alabama, Florida, West Indies and Mexico. 
Gray’s types in herb. Gray, Columbia College and J. D. 
Smith. This variety is intended to embrace all southeastern 
forms having the above characters, which will give it a some- 
what wider scope than the A. australis Gray. 
2. A. FLORIDANA Wats. Proc. Am. Acad. 10: 376. 1882. 
Tall and slender, leaves linear to narrowly lanceolate, ob- 
tuse, attenuate to a slender petiole: flowers scattered on very 
slender, strict, elongated spikes: utricle faintly angled, tuber- 
culate: staminate flowers more crowded. —Chiefly in Southern 
Florida. Types in herb. Gray, Columbia College, J. D. 
Smith and National herb. 
3. A. TAMARISCINA (Nutt.) Wood, Bot. 289 (1874). 
Amarantus tamariscinus Nutt. Trans. Phil. Soc. N. S. 5: 165. 1837. 
This species possesses in some respects the habit of Amar- 
anthus grecizans, having in common with that species slender 
and acuminate spikes, spinulose bracts and sepals, and a cir- 
Casionally found as far east as Illinois. The staminate forms 
are not easily distinguished from those of Amaranthus Tor- 
reyt, whose range overlaps that of this species on the west. 
The only specimen of Nuttall’s type seen by us is a fragment 
in herb. Columbia College collected by Nuttall in Indian 
Territory, and labelled ‘‘Salt Creek.” The specimen is very 
immature, but the locality, the slender acuminate spikes, and 
the spinulose bracts enable us to determine its place with rea- 
sonable certainty.
