12/7/2023 0 Comments Anthurium ace of spades origincerrocampanense as well as some populations of more widespread and variable species like A. Note that there are a number of species in section Cardiolonchium that do not have velvety upper leaf surfaces, such as the central Panamanian endemic A. Western and southern Colombia are particularly rich in section Cardiolonchium diversity, so the final count for the section will almost certainly be higher as previously unexplored areas of the country are botanized. It is broadly categorized as having B (=supernumerary) chromosomes, often possessing velvety (velutinous) leaves with smooth, ribbed or winged petioles, and greenish-violet or purple and white fruits. Many of these are suitable for ornamental horticulture as house, conservatory or garden plants in suitable climates. Section Cardiolonchium includes a large selection of Anthurium, currently numbering well over 250 published or accepted species ( fide Thomas Croat, Missouri Botanical Garden). It is generally assumed that these violet abaxial surfaces have evolved to reflect significant amounts of PAR that has traveled through the upper leaf surface back into inner, chloroplast/iridoplast rich tissue where it is then absorbed. Likewise, the pink or violet abaxial/underside surfaces of leaves in many of these species appear to be an adaptation shared across a wide variety of tropical forest understory plants to facilitate in capture of Photosynthetically Active Radiation (PAR i.e., the spectral solar radiation range of 400-700 nanometers) in deeply shaded environments. Nonetheless, structures that facilitate rapid leaf drying would be an advantage in the permanently wet rainforest and tropical pluvial forest ecosystems these plants inhabit. The overall dynamics between these cells and the enivironment is probably a bit more complex than originally believed. While heavily quilted or bullate leaves clearly facilitate rapid leaf drying, observations suggest that this is not necessarily the case with leaves with micro-papillose dermal cells. As was mentioned in the post on bullate-leaf anthurium species on this site, leaves with velvety or matte-subvelvety surfaces that are the result of the presence of these “convex lenticular cells” are assumed to shed water more efficiently than glossy leaves. It does not store any personal data.Epidermal cells that are micro-papillose, markedly convex or conical facilitate the capture of constantly shifting, diffuse light prevalent in forest understories.
