The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract).

Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known Anthurium spp. is a typical spadix with a large colorful spathe. [1]

The Araceae are distinguished from related families in having bifacial leaves with parallel or netted venation, usually a spadix of numerous, small flowers with a subtending spathe, endospermous seeds, and raphide crystals.

The Araceae is closely related to the Palmaceae on such grounds as small flowers arranged in a spadix and subtended by a spathe as well as the relative size of the embryo and endosperm.

Axillary, solitary or less often several per node, a densely flowered. spadix with a large subtending bract (spathe) of variable size and shape. FLOWERS. Bisexual or unisexual (the plant monoecious), actinomorphic, minute; perianth. the ovules few, the style terminal and short or wanting. FRUIT.

In Araceae that have imperfect flowers, the plants are generally monoecious. Female flowers, in this case yellow, are typically located at the base of the spadix.

Dec 2, 2022 · The spadix is a particular type of inflorescence, similar to the ear, which we can find in many species of monocotyledons. The spadix is present mainly in the Araceae family.

Araceae are best characterized by the inflorescence, a fleshy cylindric or ovoid, unbranched spadix subtended or surrounded by a spathe. True spathes are absent in the Nearctic genus Orontium and in the Australian genus Gymnostachys.

One of the most distinctive characteristics of the family is the structure of their flowers which are composed of a spadix and spathe. The spathe can be either brightly colored or green and leaf-like, while the spadix is a fleshy stem containing many small flowers.

The inflorescence is a fleshy spike or spadix subtended or commonly partially enveloped by a bract or spathe which is sometimes petaloid or brightly colored. The tiny flowers are actinomorphic, bisexual or unisexual, and are sessile or sometimes embedded in the floral axis.
