INO Lt] FLOWERING PLANTS AND FERNS ‘ 
crab apple, hackberry, and red cedar, with deciduous holly and 
honey locust in low depressions. 
On the open prairies characteristic and showy species of 
herbaceous plants are the following: 
Coreopsis lanceolata Coreopsis grandiflora 
Silphium laciniatum Silphium terebinthinaceum 
Melhiotus alba Harmannnia speciosa 
Lythrum alatum Cacalia tuberosa 
Oenothera triloba. Asclepiodcra viridis 
Asclepias tuberosa Asclepias verticillata 
Rudbeckia hirta Rudbeckia laciniata 
Sisyrinchium albidum Liatris graminifolia 
Petalostemon carneus Petalostemon corymbosus 
Otophylla Michauxii, 
Otophylla has been found in the priaries near Scooba, 
where it is frequent. Oenothera tribola, with large handsome 
lemon-colored flowers, is common around Okolona, especially 
yn open lowland pastures along creeks. 
Most. of the others mentioned in the above list are very 
characteristic prairie species and widely distributed over the 
limestone soils. Hartmannia often occurs thickly covering 
areas that are acres in extent, and in the spring the large pink- 
ish flowers densely massed form a handsome and striking cover- 
ing to the gently undulating prairie surface. 
On the lighter and usually higher reddish soil areas which 
dot the prairie surface like islands, an entirely different assem- 
blage oceurs. This soil is not so rich in plant food as the black 
soils, lime especially being in much smaller proportions. These 
areas support a rather dwarfish growth of a few species of 
trees, chiefly oaks, the commonest being: 
Quercus minor Hicoria Alba 
Quercus Marilandica. Diospyros Virginiana 
Quercus digitata Pinus echinata 
Quereus velutina Prunus serotina 
Quereus Durandi
