Between Rhapis and Lantana, which genus has the most number of species?
Lantana Lantana is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae. They are native to tropical regions of the Americas and Africa but exist as an introduced species in numerous areas, especially in the Australian-Pacific region. The genus includes both herbaceous plants and shrubs growing to 0.5 - tall. Their common names are shrub verbenas or lantanas. The generic name originated in Late Latin, where it refers to the unrelated "Viburnum lantana".
Daubenya zeyheri Daubenya zeyheri (Kunth) J.C.Manning & A.M.van der Merwe is one of 8 bulbous species in the genus, all endemic to the winter rainfall Strandveld of South Africa, and mostly growing on doleritic clays along the West Coast, Western Cape. It is closely related to "Daubenya marginata" (Willd. ex Kunth) J.C.Manning & A.M.van der Merwe. At first believed to consist of a single species, "Daubenya aurea", the genus was expanded in 2000 to include the genera "Androsiphon" and "Amphisiphon" and various species that had previously been classified as "Polyxena", "Massonia", or "Neobakeria". ""The poor congruence between morphological and other characters within Hyacinthaceae has also made generic circumscriptions very difficult. One of the consequences of this has been the recognition of a large number of genera that are poorly defined morphologically."" - (Speta 1998) All 8 species have two spreading, prostrate leaves and tubular flowers that range from white to yellow or red, and in 6 of the species are followed by smooth glossy seeds within papery capsules that lend themselves to anemochory or wind dispersal. The inflorescence is produced at ground level on a sub-surface peduncle between the two leaves. Species are variously pollinated by bees, butterflies, moths, the monkey beetle "Lepisia glenlyonensis" and sunbirds. The water-retaining nature of doleritic clays ensures their remaining moist for longer than clays formed from shales of the Karoo series. Exceptionally "D. namaquensis" is found in deep red sands and "D. zeyheri" in calcareous coastal sands.
