Much uncertainty has arisen from attempting to reduce A. hypericoides lo a 

 form of A. Crux-Andre;v, but the larger more branching habit, narrower leaves 

 with conspicuous basal glands, as well as a decidedly more southern range, serve 

 to distinguish it. The Bermuda and Jamaica plants are typical forms of the spe- 

 cies, and can by no means be taken for forms of A. Crux-Andrese, but those of 

 the continent are more apt to be perplexing. The specimens examined were 

 from S. Carolina (Ravenel), Flor.'da {Curths, 243), Louisiana (Drummond, 90 and 

 92), Texas (Hall, 36 in part, Lindheimer) , Mexico (Beiiandier, 989, 2419, Botieri, 

 373), Cuba ( Wright, 2129), Jamaica {Alexander, Grisebach, 1497. 811), Bermuda 

 (Lane, 331 in part). 



** Erect, stouter, a foot or two high : stems simple or branched above, con- 

 spicuously two-edged, even winged: leaves broader and thicker, more or less 

 clasping: pedicels 2 to 6 lines long: inner sepals 3 to 6 lines long, sometimes 

 as long as the outer, seldom petaloid : petals mostly much longer than the outer 

 sepals: styles 3 (rarely 4), generally distinct. 



4. A. stalls MiCHX. Leaves oblong to oval, closely sessile ami 

 somewhat clasping, an inch or two long and 5 or 6 lines wide : 

 pedicels bibracteolate near the middle : outer sepals ovate to orbicu- 

 lar-cordate ; inner ones lanceolate : styles short. — FI. ii. 77 ; 

 Chois. in DC. Prodr. i. 555 (but not " 2-styled ") ; Torr. & Gray, 

 Fl. i. 157; Gray, Gen. 111. i. 212, t. 91.

Barrens of New .Jersey and E. Pennsylvania to Florida, Louisiana, and W. 

 Texas, 



lu a southern form (var. obovatum Chapm.) the lower leaves taper to the 

 base and become almost obovate. The specimens examined were from New 

 Jersey (many collectors), E. Pennsylvania (Porter), Florida (Curtiss, 244), Lou- 

 isiana (Drummond, 91, also Hale, a very large specimen), W. Texas ( Young). 



5. A. aniplexicaule Michx. Leaves ovate -cordate, often 

 broadly so, clasping, half an inch or more long and nearly as wide : 

 pedicels with very small bractlets near the base or none : outer 

 sepals broadly ovate-cordate, resembling the leaves; inner ones 

 linear-lanceolate : styles about as long as the ovary. — Fl. ii. 77 ; 

 Torr. & Gray, Fl. i. 157.
