Developing leaves emerging from a bulb of a hybrid Hippeastrum,the winter-flowering houseplant commonly known as Amaryllis. The picture shows three leaves growing from the centre of the bulb,with the dry outer scales of the bulb to the bottom of the picture. The veins in the leaves are parallel to another ( seen as faint vertical striping here ). Parallel venation is characteristic of leaves of monocotyledonous plants. Bulbs are large underground buds,consisting of a conical stem at the base to which are attached concentric rings of scale-like leaves containing stored food. During growth,roots appear from the base of the stem,and the most central leaves expand. Hippeastrum is a genus that is native to Central and South America,and is a member of the family Amaryllidaceae. Amaryllis is correctly the name of a separate genus of the same family that is native to South Africa | |
