| Short description | Abutilon albescens +/- Wollastonia uniflora low shrubland, restricted to coral, shingle and sand cays |
| Structure code | Shrubland |
| Description | Abutilon albescens +/- Wollastonia uniflora low shrubland. The shrubland formation of Abutilon albescens is 0.4-2 m tall with 15-35% FPC, whereas the open heath is 1-1.5 m tall and 35-70% FPC. Some of the Abutilon albescens stands are monospecific. Other species frequently recorded include Wollastonia uniflora, Ipomoea violacea, Lepturus repens (0.4 m, 10-15% FPC), Achyranthes aspera (0.4 m, 5-10% FPC), Plumbago zeylanica (0.4 m, 3% FPC), Boerhavia albiflora var. albiflora (2% FPC), B. mutabilis (2% FPC), *Portulaca oleracea (<1% FPC), Sporobolus virginicus (<1% FPC) and Tribulus cistoides (<1% FPC). In some situations Guilandia bonduc may be an abundant scrambling shrub. Litter cover ranges from 15-35%. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a).
