Figure 1 in Variable foraging and flower probing behaviour of sunbird pollinators of the South African Pelargonium fulgidum

Figure 1. Pelargonium fulgidum plants and Cinnyris chalybeus sunbird pollinators. (a) Plants of P. fulgidum flower in dense coastal scrub on sand dunes along the west coast of South Africa. (b) Top view of the fan-shaped P. fulgidum inflorescence, showing the number of open flowers and the angles among open flowers and peduncle. (c) Side view of P. fulgidum inflorescence, showing the angles of peduncle and pedicels. (d) Male C. chalybeus with its slightly decurved bill. (e) Pelargonium fulgidum flower in longitudinal cross section, showing the slightly upcurved nectar tube and the reproductive parts partly blocking the flower entrance. Scale bars: b, d = 10 mm; e = 5 mm.
