Succulent Plants of Ohio.

storing up enough water to last from one rainy season to another. 
These cells are highly specialized, being comparatively large and 
with thin walls. Many of the typical leaf succulents develop 
rosettes as in Sempervivium tectorum. 
Stem succulents have thickened fleshy stems which perform 
the functions of leaves. Here the stomata are found in the epi¬ 
dermis as in the foliage leaf and the green tissue is contained in 
the cortex. In many stem succulents the stem becomes leaf¬ 
like, or disk-shaped as in Opuntia. 
Among the fleshy, watery plants found in our moist woods 
Galeorchis spectabilis is characteristic, while Adicea pumila is 
a good example of the annual plants with delicate watery stems. 
Probably our most abundant succulent, present almost every¬ 
where in gardens and fields, is the common Purslane, Portulaca 
oleracea. 
In the following list, the Ohio plants which might be con¬ 
sidered in this connection have been arranged under two heads: 
first a list of the more typical succulents, and second a general 
list containing some of the semi-succulent plants present in our 
flora.
