Taxonomic Notes

Synonym(s): G. frondosa (Linnaeus) Torrey & A. Gray ex Torrey var. tomentosa A. Gray;[1][2] Decachaena tomentosa (Pursh ex Small) Small[2]


G. tomentosa is a dioecious perennial shrub.[1] It grows low and spreads locally via underground stems. Leaves are 2.5-7 cm (1-2.8 in) long, leathery, oblong or elliptic, and obtuse and apiculate at the apex. Pedicels are 1-1.5 cm (0.39-0.59 in) long and the calyx is glabrous and about 3.5 mm (0.14 in) wide. It is typically found in sandy soils.[3]


Its primary distribution extends north from central peninsular Florida to central Georgia and southern South Carolina and westward to southwestern Alabama.[1][2] Occurrences have also been reported in a southern county of North Carolina and a northern county in Georgia.[1]



This species inhabits pine flatwoods, sandhills, and xeric coastal fringe sandhills.[2]


G. tomentosa has been observed to flower from March through May.[2][4] Fruits mature afterwards from June through August[2][3]

Fire ecology

In Osceola National Forest, Florida, a burn frequency of 2 years yielded the greatest coverage of G. tomentosa, although it remained present in the 1 and 4 year fire interval treatments as well.[5]
