leaves and clustered, waxy berries. It is associated with a low oak, Quercus 
pumila Walt. (M.), on the east coast and on the west coast with Quercus 
minima (Sarg.) Small (F.) and Quercus myrtifolia Willd. (F.), sometimes 
6 meters (20 feet tall). Quercus myrtifolia Willd. is a much-branched ever- 
green shrub and its acorns mature the second year, while the fruits of 
Quercus pumila Walt. mature the first year. Quercus minima (Sarg.) Small 
has persistent leaves. The gopher-apple, Geobalanus oblongifolius (Michx.) 
Small, with underground stems and ovoid drupes, occurs in the forests at 
Miami and Ft. Myers. Several ericaceous shrubs suggest the pine barrens 
of New Jersey. They are Vaccinium nitidum Andr. (M.), Vaccinium myrsin- 
ites Lam. (S. F.), Gaylussacia dumosa (Andr.) Т. & С. (S.) found in New Jersey, 
Xolisma fruticosa (Michx.) Nash (S. F.) and Bejaria racemosa Vent. Vac- 
cinium nitidum Andr. grows about a foot high and has small, almost sessile, 
pointed leaves and grayish bark, while Vaccinium myrsinites Lam. is a low 
much-branched shrub with box-like leaves in fruit June 6, 1912. Xolisma 
fruticosa (Michx.) Nash., in flower on June 6, has leathery, rusty-looking 
leaves. The evergreen shrub, Bejaria racemosa Vent., was gay with its glu- 
tinous white corollas with narrow spatulate petals. Before leaving Florida 
at the end of June, it had begun to fruit. A celastraceous shrub, Crossopetalum 
floridanum Gardner (=Rhacoma ilicifolia (Poir.) Trelease), has a deeply pene- 
trating tap-root and spreading almost prostrate branches with holly-like leaves. 
Other low shrubs are Byrsonima lucida (Sw.) DC. (H.), Asimina reticulata 
Shuttlew. (S.), Croton Fergusonii Small (H.), Rhus obtusifolia Small, 
Rhus toxiferum (L. H.), Hypericum aspalathoides Willd. (S.), Ascyrum 
tetrapetalum (Lam.) Vail, Tetrazygia bicolor (Mill.) Cogn. (H.), Icacorea 
paniculata (Nutt.) Sudw., Guettarda scabra Vent (H.), Lantana depressa 
Small (H.), L. involucrata L. (M.), Callicarpa americana L. (F.), and Ximenia 
americana L. The greenbriar, Smilax Beyrichii Kunth, is a liane, found com- 
monly near Ft. Myers. At the western extension of the east coast oólitic 
limestone formation, Long Key in the Everglades is remarkable, according to 
Small, for a number of shrubs found beneath the dominant slash-pine trees. 
Among these shrubs may be mentioned Torrubia longifolia (Heimerl.) Britton, 
Ilex Krugiana Loesil, Exothea paniculata (Juss.) Radlk., Jacquinia keyensis 
Mez., Icacorea paniculata (Nutt.) Sudw., Dipholis salicifolia (L.) A. DC. 
(Plate IV).
