Today we deal with three more monocot subclasses. These
include some very showy plants!
1. Araceae--Herbs, flowers unisexual, on a spadix subtended
by a spathe. Includes many plants grown for foliage, e.g. Pothos,
etc. Ex. Arisaema.
1. Bromeliaceae--Herbs, usually epiphytic, flowers
perfect, regular, subtended by showy bracts. Ex. Tillandsia(ball
moss and Spanish moss) with comose seeds and Ananas (pineapple)
with multiple fruit.
1. Liliaceae--Herbs, often from bulbs, flowers with 6 tepals, ovary superior.
Ex. Nothoscordum, Allium (onion, garlic,
2. Amaryllidaceae--Herbs, often from bulbs, flowers with 6 tepals, ovary inferior.
***Note these two families are sometimes "lumped" into
the Liliaceae (s.l.)****
3. Orchidaceae--Herbs, often epiphytic, flowers highly modified with lip (labellum) and column; pollen in pollinia; pollination mechanism often quite species-specific; seeds numerous, small, underdeveloped. Thousands of species and thousands more cultivars. Ex. Cattleya (often in corsages), Vanilla, Spiranthes. Our local species are all terrestrial; tropical species are often epiphytes.
