124 Harper: Trip oN WARRIOR AND TOMBIGBEE RIVERS 
in Marengo County, Oct. 14. Not previously reported from 
Alabama. 
Paspacum MucronatuM Muhl. (P. flwitans Kunth). 
Not rare, on shaded alluvial banks, Tuscaloosa (x0. 176), 
Sumter, Marengo, Choctaw, and Washington counties. This, too, 
was new to the known flora of the state. 
Pinus PAtustris Mill. 
The only places between Tuscaloosa and Jackson where this 
is visible from the river seem to be the crests of the high Buhr- 
stone ridges or ‘‘mountains’’ above mentioned, in Choctaw and 
Clarke counties. There a few specimens of this unmistakable 
pine could barely be distinguished with the naked eye as we floated 
along. It also grows to some extent on the hills capped with 
Lafayette red loam around Jackson. 
? EQUISETUM ARVENSE L. 
Sterile specimens which cannot be distinguished from this 
species were collected in damp crevices of Ripley (Cretaceous) 
limestone at Barton’s Bluff in Marengo County, about ten miles 
below Demopolis (wo. 727). This is just the kind of a place in 
which one usually finds Equisetums (mostly of the Ayemale group) 
in the South, but the finding of &. arvense in Alabama was 
decidedly unexpected. Dr. Gattinger reported it from “ moist 
fields, Cave Spring, E. Tenn.,”’ and Dr. Small in his Flora of the 
Southeastern U. S. credited it to North Carolina, without definite 
locality, but these are the only records of its occurrence in the 
southeastern states that I have found. &. arvense in the North 
is often if not usually a weed, but these specimens appeared 
decidedly native. 
Perhaps if my locality could be visited in spring when the 
fertile stems are visible this plant would turn out to be something 
else than £. arvense ; but it is certainly not one of the three species 
credited to Alabama by Dr. Mohr, for those are all of the Ayemale 
group. 
ASPLENIUM ANGUSTIFOLIUM Michx. 
Many fine specimens of this, some fruiting (m0. 129), were 
found in rich shady woods on the north side of a steep Buhrstone
