may be one of the chief causes preventing development of under- 

 growth, but the presence of these low shrubs adjoining bays and 

 ponds, where fires have been able to do small damage to the natural 

 growth, seems to prove the character of the shrubbery. Dwarf 

 oaks are common (Q. myrtifolia Willd., Q. minima Small, and Q. 

 nana Willd.), with persistent, leathery leaves and mostly bearing 

 abundant fruits. Myrica cerifera pumila Michx., M. carolinensis 

 Mill., Ilex glabra Gray, Hypericum myrtifolium Lam., H. galioides 

 Lam., H. aspalathoides Willd., H. opacum T. and G., and Kalmia 

 hirsuta Walt, are other shrubs with persistent foliage. Pyrus 

 arbutifolia L. f., Rhododendron nudiflorum Torr., R. viscosum Torr., 

 Lyonia nitida Fernald, Andromeda ferruginea Walt., Vaccinium 

 stamineiim L., and V. Myrsinites Lam. are also shrubs of the damp

to wet sands. 



The most conspicuous index, however, of subsoil more or less 

 saturated is Serenoa serrulata Hook. f. (saw palmetto). As soon 

 as this palmetto appears with the turpentine pines, poor drainage 

 is to be inferred. The herbs also are strikingly characteristic of 

 undrained soil with its lack of aeration and consequently of assimi- 

 lable nitrogenous substances. The Leguminosae, so abundantly 

 represented on the Sandhill soil and in the long-leaved pinewoods 

 on the dry sands, do not appear. Besides the grasses and Com- 

 positae, the families most in evidence here are Eriocaulaceae, 

 Juncaceae, Liliaceae, Orchidaceae, Sarraceniaceae, Droseraceae, 

 Polygalaceae, Melastomaceae, Onagraceae, Gentianaceae, Scrophu- 

 lariaceae, and Lentibulariaceae. Representatives of these familes 

 are Eriocaulon decangulare L., E. compressum Lam., Juncus Elliot-
