Description
Generally, Galium genus are "perennial or annual herbs, the stems weak, often scabrous; the roots often red or orange. Leaves whorled, entire. Flowers in simple or profusely branched cymes or the inflorescence reduced and the flowers 1-several and axillary; sepals usually obsolete, corolla rotate, 3-5 lobed; stamens 3-5. Fruit dry or sometimes fleshy, indehiscent, subglobose or reniform, or if the two carpels both develop and stay together the fruit broader than long." [1]
Specifically, for this species, G. pilosum are "perennial, the stems erect or ascending, unbranched except in the elongate inforescence, 3-8 dm tall, smooth, pilose. Leaves 4 per node, elliptic to weakly ovate, 1-2.5 cm long, 6-12 mm wide, mucronate, pilose-hispid, glandular-punctate beneath. Corolla white, greenish or shaded with maroon. Fruit dry, brown, or black, bristly, 2-3 mm long, 3-4 mm broad." [1]
Distribution
Ecology
Habitat
This species has been found in wet flatwoods, mixed hardwoods, longleaf pine-wiregrass savannas, coastal and cabbage palm hammocks, river floodplains, rich woodlands, grassy and shrubby thickets, coastal dunes, sandy ridges, and near ponds. They are found to grow in partial shade and under open canopies of pinewoods in well drained moist sandy soils, drying loamy sands, limestone outcrops, or dry loamy sands during drought. They also have been observed growing in disturbed areas such as picnic areas, along roadsides, in powerline corridors, along trails, on sand pine plantations,in borrow pits, on bulldozed areas, and in "battered" limestone glades[2]. Associated species includes Smallanthus, Schisandra, Collinsonia, Nyssa, Ulmus, Pinus, Quercus, Carya, Aristida stricta, Acer, Magnolia, Ilex, Aesculus, Pinus elliottii, Giallardia pulchella, and Quercus laevis. Also includes cabbage palm[2].
Phenology
This species has been observed flowering from June through August and October through November and fruiting from June through November[2].
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses being carried externally by vertebrates. [3]
Fire ecology
This species can be found in annually burned pinelands (FSU Herbarium).
