Table 1: Nectar sugar properties <strong>of</strong> Plectranthus and other species analysed in this study, using<br />
Gas Chromatography (GC), with an indication <strong>of</strong> main pollinator class. Plant vouchers are<br />
lodged at Bews Herbarium (NU).<br />
CP: C. Potgieter, NV: no voucher; Fr: Fructose, Gl: Glucose, Su: Sucrose; S/H nectar: ‘True’ nectar<br />
sugar class dominance; S: more than 50% sucrose, H: more than 50% hexose; B&B nectar: Nectar<br />
sugars classified according to Baker & Baker (1983a); HR: ‘hexose-rich’, HD: ‘hexose-dominant’,<br />
SR: ‘sucrose-rich’, SD: ‘sucrose-dominant’; Apin: Bee (Apidae, Apinae), Mega: Bee (Apidae,<br />
Megachilinae), Nem: Fly (Nemestrinidae), Acro: Fly (Acroceridae), Tab: Fly (Tabanidae). Species<br />
marked with an asterisk* are visited for nectar by the nemestrinid fly, S. wiedemanni, or expected to<br />
be visited by a Stenobasipteron species.<br />
