Taxonomic notes

Synonyms: Galium pilosum Aiton var. pilosum; G. pilosum Aiton var. puncticulosum (Michaux) Torrey & A. Gray


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]




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]


G. pilosum has been observed flowering in March, from May through August and October through November with peak inflorescence in June.[3][2] It has been observed fruiting from June through November.[2]

Seed dispersal

This species is thought to be dispersed by translocation on animal fur or feathers. [4]

Fire ecology

This species can be found in annually burned pinelands.[2] It has been observed flowering in July following a March prescribed burn in research plots in a longleaf pine-wiregrass native community in southern Georgia.[5]
