The scape (flowering stalk) is erect, leafless, terete, or compressed. The flowering stem is usually leafless or with just one or two small leaves. In "Dicentra", all leaves are in a basal rosette, and flowers are on leafless stalks. The plants are scapose, having a single central leafless hollow flower stem (scape). Plants in the genus "Cymbidium" are epiphytic, lithophytic or terrestrial plants, or rarely leafless saprophytes. Leafless cacti carry out all their photosynthesis in the stem, using full CAM. The flowers form an umbel at the top of a leafless stalk. In a completely leafless tree, the blossoms look like a net. The plant is a rosette-forming perennial herb, with leafless, silky, hairy flower stems (). They have leafless (or apparently leafless) flattened stems which act as the plant's photosynthetic organs. They do not obviously resemble a typical leafless cactus such as an "Echinocactus". His symbol is a leafless tree in a field of snow. The highest amount of herbivory was on "B. trifoliolata" vines that climbed onto leafless hosts. Two men, Vladimir and Estragon, have met near a leafless tree.
