“…Nitidulids are important pollinators for several plant families, such as Annonaceae (Gottsberger 1999;Silberbauer-Gottsberger et al 2003;Teichert et al 2011;Saunders 2012) and Arecaceae (Listabarth 1996;Fava et al 2011). Our study of a broad range of species supports the findings of Hattingh and Giliomee (1989), who found P. cinerascens to be the main pollinator of L. microcephalum, L. salignum, and L. laureolum. Individuals of P. cinerascens were found in abundance on male Leucadendron inflorescences, where they fed on pollen and reproduced.…”

“…Similar patterns for high seed set in Leucadendron were reported by Collins and Rebelo (1987) and Hattingh and Giliomee (1989). These findings support Midgley and Bond's (1991) suggestion that wind pollination can be highly effective and a viable alternative to insect pollination in angiosperms.…”

“…A small pollen beetle, Pria cinerascens Er. (Nitidulidae), is often associated with Leucadendron flowers, particularly the male inflorescences, where they feed on pollen and breed (Williams 1972;Hattingh and Giliomee 1989;Hemborg and Bond 2005). Williams (1972) suggested that at least six species are wind pollinated because of morphological changes such as a lack of conspicuous colored involucral leaves, a reduction of the hypogynous scale (nectaries), increased size of the female stigmatic surface, a lack of distinct floral odor, and showering of pollen when branches are shaken.…”

“…f. was that of Leucadendron and probably of this species, highlighting the possible efficiency of wind pollination, although they did not test for the possibility of insect pollination. In a pollination study on several Leucadendron species, Hattingh and Giliomee (1989) found that exclusion of insects but not wind had little effect on seed set in Leucadendron coniferum (L.) Meisn. To our knowledge, this was the only previous experimental investigation of wind pollination in a Leucadendron species.…”

Evolutionary transitions from insect to wind pollination are thought to have occurred many times during the angiosperm radiation. On the basis of floral features, several such transitions have been postulated for Leucadendron (Proteaceae), a dioecious genus of 96 taxa confined almost entirely to the Cape Floristic Region. To confirm whether these transitions took place, we carried out experimental tests for wind pollination and sampled insect flower visitors in 15 Leucadendron species, representing six clades in the genus.Methodology. In three clades in which an insect-wind shift has been inferred, we sampled species with traits suggestive of either wind or insect pollination. Plants were bagged with fine-mesh exclusion bags that excluded insects but allowed the passage of airborne pollen. Insects visiting female inflorescences were collected for identification and analysis of their pollen loads.Pivotal results. We found that insect exclusion had little effect on seed set of five species conforming to the wind pollination syndrome (L. rubrum, L. salicifolium, L. dubium, L. coniferum, and L. teretifolium), while seed set was strongly reduced by insect exclusion in the remaining 10 species conforming to an insect pollination syndrome. The most common pollinator of the insect-pollinated species was the nitidulid beetle Pria cinerascens.Conclusions. This study provides experimental verification of contrasting insect and wind pollination systems in Leucadendron and will thus enable formal phylogenetic tests of adaptive changes in floral traits, such as color and scent, that may be associated with pollination system transitions in this diverse lineage.

The poor quality of proteas as a source of insect nutrition may limit certain protea arthropod species and their abundance (Wright & Giliomee 1992), while, in contrast, the structural complexity typical of most protea plants may provide a diversity of microhabitats and enemyfree space which favour various arthropod groups and hence diversity (Lawton 1983;.…”

More than 1400 species have been recognized in the ancient Proteaceae family (Rebelo 1995). Their occurrence is mostly distributed between Australia with about 800 species and Africa with about 400 species with the remainder found in South America, the islands east of New Guinea, and a few species in southeast Asia, New Zealand, and Madagascar. They are broadly referred to as proteas, although we identify specific genera by their Latin names. The subfamily Proteoideae, largely found in Africa, has contributed the genera Protea, Leucadendron, and Leucospermum to floricultural trade, while the Australian Grevilleoideae has contributed Banksia and Grevillea that have found similar use in floriculture and landscaping. Other genera are still emerging in importance (Criley, 2001
