with long ariste and short wide dentate staminodia, which 
resemble those of A. paronychioides, but with fewer teeth.— 
Native of southern Mexico and South America, but intro- 
duced at Mobile, Alabama. It is not known to be abundant 
anywhere. 
Although this species is referred to by Moquin-Tandon among 
‘‘Spectes non satis note,” one of the specimens studied (Para- 
guay Morong 39) was identified by Dr. Britton at Kew, 
thus further confirming the decision already reached ex char. 
The smaller-leaved forms approach A. repens very closely, 
but the staminodia character serves to give it specific rank. 
Type unknown. 
3. A. PARONYCHIOIDES St. Hil. Voy. Brés. 2: 43. 1823. 
Habit of A. repens, but less diffuse, with glabrate stem 
freely rooting at the nodes, narrower leaves with longer 
petioles, strongly compressed flowers, thin acute sub-equal 
pearly-white hairy sepals, much exceeding the utricle, short 
wide 3-dentate staminodia, and strongly compressed obcor- 
date broadly margined utricle.—North Carolina, southward 
throughout the gulf states near the gulf. Native of the low- 
land tropics. 
This species has been generally confused with A. repens, to 
which the specimens in our herbaria have mostly been re- 
ferred. It may be recognized at once by its thin, white, os 
aristate sepals, although its more deep-seated distinction lies 
in the staminodia. This, and the next preceding, show more 
strikingly than any other forms the intimate relation of Al- 
ternanthera to Telanthera, occupying a position directly in- 
termediate between A. repens on the one hand, and 7. ficot- 
ea on the other, both in habit and in the character of the 
Staminodia. Related also to A. pilosa of South America. 
Type unknown. 
*** Staminodia long (equaling or surpassing the filaments), 
toothed or fringed. 
+ Calyx sessile.

lower ones putting out numerous long fibrous roots: leaves 
small (3™ long or less), narrowly spatulate, crowded: heads 
very small, sessile in the axils: bracts short, wide, deeply la-
