Abstract: A new variety of leatherleaf fern having a diamondlike shape, arose as a vegetative mutation from a plant of Rumohra adiantiformis (Forst.f.) Ching that was under normal cultivation conditions. Through successful propagations by both rhizome division and meristem tissue culture, it has been ascertained that the specimens of the new variety may be distinguished from those of the parent by the fronds, which are more densely foliolate, more complanate, more symmetrical in the foliate portion of the frond, with pinnae tending to be subopposite, of a darker color, larger size, and with a fuller distal acumination. The new variety has advantages for cut flower arrangements because the complanate pinnae present a pleasing and full appearance, thus improving the aesthetic and market value of the arrangements. The superior lasting qualities and resistance to fading of the deep green color further enhances the utility of the foliage over a spectrum of end products.

Abstract: A sport of Rumohara adiantiformis (Leather Leaf Fern) is described. The sport is characterized by difference in the fronds, which are denser, much flatter, darker in color, and larger and possess a more pronounced point at their terminal end.
