structure of leaf of bryophyllum? |
The leaves are also fleshy (i.e. succulent) and are either simple (particularly on seedlings) or compound (i.e. trifoliate or pinnate). They are oppositely arranged, flattened, and the number of leaflets present varies from one near the base of the stems to three or five (i.e. trifoliate or pinnate) higher up the stems. These leaves (5-25 cm long and 2-12.5 cm wide) are green or yellowish-green in colour, hairless (i.e. glabrous), and are borne on stalks (i.e. petioles) 2-10 cm long. The leaflets are oval or narrowly oval (i.e. elliptic) in shape with rounded tips (i.e. obtuse apices), and when more than one leaflet is present the end (i.e. terminal) leaflet is usually significantly larger than the others. Tiny plantlets may occasionally be formed in the scalloped (i.e. crenate) margins of these leaflets. These plantlets are more often produced if the leaves become detached from the stems. bryophyllum |
