62 Plants from Alabama. 



This plant is found in company with the A Glandulosa m 

 the prairies* of Green county, Alabama. In habit it conside- 

 rably resembles the Schrankia Uncinata, for which it might 

 be mistaken by a superficial observer, when not in flower; 

 flowers golden yellow ; stamens, longer than the corol- 

 la, ten in number; peduncles about an inch and a half in 

 length ; first found in August, probably in flower also in the 

 month of July. 



Malva Triangulata. Hirsuta, subdecumbens. Fo- 



liis, inferioribus triangulari-cordatis; superioribus 3-ad 

 5-lobatis, irregulari-dentatis. Floribus racemosis. 

 This plant is found in Montgomery county, Alabama, a 

 foot or more in height, somewhat pubescent. Flowers 

 purple, handsome ; found in July. This may be the M. 

 Triloba of Nuttal, of which I have not seen any descrip- 

 tion. It is however probably a different species.

 busmultifidis; laciniis linearibus : floribus racemosis. 

 Flowers in March ; about four or five inches in height,

 racemes which are somewhat secund ; flowers of a middle 

 size, purplish ; found in the Cherokee country.

* The prairies of Alabama rest on a soft limestone rock abounding in 

 shells noticed in Mr. Finch's memoir (Pa. 41 ) as an extensive expansion 

 of his formation of Calcaire Ostree. Their surface is rolling, soil deep 

 black, very adhesive when wet, covered with luxuriant grasses, and in the 

 proper season, with a profusion of gay flowers. There is wood enough on 

 the prairies to fence them. It is arranged in lines and clumps on the lower 

 and moister portions, dividing them into open spaces of several hundred 

 acres. The soil is of variable depth and rests on a uniform bed oflime- 

 stone. In some places the rock juts out on the surface, where it easily de- 

 composes. There is a great deficiency of water, particularly in dry seasons, 

 and what there is of it, is very bad. The limestone rock has not been perfo- 

 rated even at the depth of three hundred ieet
