Spadix Inflorescence 

4
Anthurium 

A Spadix is a type of inflorescence found in the Araceae family.

It consists of a spathe, which is simply a large leaf-like bract, colourful or showy, to attract pollinators. Spadix is the cylindrical inflorescence, basically a spike, with small flowers on a thickened, fleshy axis and it is protected by the spathe in bud stage.

Many Aroids are ornamental plants due to the Spadix and Spathe.

The sap of Aroids contains needle-like calcium oxalate crystals, which can be mildly toxic and can irritate hands and sensitive tissues. However, not all aroids are toxic and used as vegetable, including their leaves.

Some members of this family reproduce by seeds, whereas many have vegetative propagation.

The inflorescence of species such as Titan arum gives off a very pungent smell, often resembling rotten flesh.

Grass inflorescence

S1
Lemon grass- Cymbopogon citratus

It may not seem like grasses are flowering plants to a layman as the grass flowers don’t look quite like the showy colorful parts most people recognize as flowers. Grasses are definitely flowering plants.

The flowers or inflorescence is called a “spike” or sometimes a “panicle.” Though individual flowers are not attractive, the inflorescence is very much noticeable and some of the ornamental grasses have pretty spikes.

Grasses belong to a large and nearly ubiquitous family of monocotyledonous flowering plants known as Poaceae or Gramineae. This includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns and pastures.

Some grass flowers are presented in this post.
