I have a large Neobenthamia and as Pheli said the leaves are like grass. It has long stems and the grass
like leaves grow alternately up the stem. It flowers from the very top of the stem with little pom-pom heads of about 12-15 cute little white flowers. It seems to be quite hardy and likes quite high levels of light. Mine throws heaps of keikis from the joints on the stems and new shoots from the base of the plant. I have potted up heaps of keiki's and they take very well.
