About the Subfamily Pitcairnioideae

Pitcairnioideae is a subfamily of plants that contains many genera and species. All Pitcairnioideae belong to the family Bromeliad. There are a total of 16 recognized genera and over 1000 recognized species in this subfamily. Some of the most noted genera are the Dyckia, which contains 130 species, the Sequencia, which contains only one species and the Piticairnia, which contains over 300 species.

Characteristics

Some characteristics are shared by all members of this subfamily of plants. All species are either terrestrial or saxcolous, which means they grow on rocks. The plants are common at high altitudes and especially in arid regions. They have evolved to have very fleshy leaves and many species have spines on the edges of their leaves. This helps prevent predators from eating the plants. The flowers of the plants are full of small, wingless seeds. These are spread by animals and by the wind.

The mature Pitcairnioideae

Most mature Pitcairnioideae have complex root systems. This helps them find water in dry environments and shuttle it up to the parts of the plant that need it the most. Water is often caught in the bowl-shaped indent of the leaves. The thick leaves are actually designed to give the plant a barrier between the plant and the harsh sun.

Pitcairnioideae is an interesting subfamily that contains many similiar, but unique members. Those who wish to learn more about this type of plant need only keep their eyes open. Pitcairnioideae are in high demand these days since they are so functional and still look relaxed and earthy.
