Figure 7.

Pollen of Lorantheae: Loranthinae, Amyeminae, Scurrulinae, and Dendrophthoinae. Pollen images (polar views) are mapped on the corresponding part of the bipartition network shown in Figure 3; Clades G–J according to Vidal-Russell and Nickrent (2008b) are indicated. Pollen of Loranthus (Loranthinae, Clade G) differs by its zonocolpate aperture organisation (particular on the distal face of heteropolar grains), where the colpi do not join at the pole (a), and the straight-triangular outline in polar view (b′) in contrast to convex-triangular to trilobate (b). Colpi are usually ± narrow, occasionally widening towards the pole joining in a polar depression (c). Note the trend towards T-shaped apices (d) and formation of more or less developed triangular polar protrusions (e) of the more or less prominent margo in the core Lorantheae (Clade J).
