Keeping Tropical Flowers |
Type of tropical flower – the division CycadophytaCycads form a very old group of seed plants. Cycads were extremely common during the Jurassic period and some of them have survived into our time. They can look similar to palms or ferns, but they belong to their own division: Cycadophyta. This type of tropical flower has a large crown made up by compound leaves and the trunk is characteristically tubby. All cycads are evengreens with big pinnately compound leaves. They are dioecious, i.e. some specimens produce only male flowers (androecious) while others produce only female flowers (gynoecious). This type of tropical flower can sometimes form symbiotic relationships with cyanobacteria (blue-green algae) to fix nitrogen. The Cyanobacteria will also create a neurotoxin which is present in the fruits of these plants. Cycads are found in tropical and subtropical parts of the world. The richest diversity is found in South and Central America, but you can find this type of tropical flower in many other regions as well, such as the Pacific Islands, South East Asia, Australia and tropical Africa. Type of tropical flower – family EuphorbiaceaeThe family Euphorbiaceae is also known as the Spurge family. All spurge species are flowering plants; some are herbs while others are shrubs or trees. Shrubs and trees are most common in the tropics. This type of tropical flower can resemble a cactus, but it is not a true cactus. The stipules are sometimes altered into spines, hairs or glands. In succulent species, they can be completely absent. In most cases, there will be male and female flowers present on the same specimen. This type of tropical flower is especially common in the Indo-Malayan region and tropical America. Type of tropical flower – family OrchidaceaeThe family Orchidaceae is an extremely diverse family of flowering plants. The richest assortment of species is found in tropical and subtropical parts of the world, but you can find orchids in colder climates as well. All members of the family Orchidaceae is protected under CITES as potentially threatened or endangered, but hybrids are not included. Advanced orchids typically display five common characteristics. The flowers display bilateral symmetry and have a column (gynostemium). The pollen is glued into a pollinia, a congregation of waxy pollens on filaments. The seeds are usually extremely small and have no food reserve, but there are exceptions to this general rule, including the well-known members of the genus Vanilla. The seeds form a symbiotic relationship with certain fungi, and without the presence of suitable fungi they can not germinate under natural circumstances. Type of tropical flower – family BromeliaceaeThe Bromeliads make up a broad family of flowering plants that includes both terrestrial plants and epiphytes. Christopher Columbus is generally recognized as the first European to encounter this type of tropical flower and he brought back Ananas comosus, the pineapple, to Spain. It is common for this type of tropical flower to have the ability to store water in a form of tank created by tightly overlapping leaf bases. The biggest known member of this family is the Puya raimondii which can reach a height of 4 metres and form a 10 metre tall flower spike. Type of tropical flower – family AnnonaceaeThis group of flowers is also known as the Soursop family or Custard apple family. It comprises trees and shrubs as well as lianas. A few species grow in temperate regions, but the vast majority of the 2000+ species belong to the tropics. This type of tropical flower is native to Asia, Africa and the Neotropics. The flowers display radial symmetry and are usually bisexual. The most common configuration is three sepals, six petals, plenty of stames and many pistils. There are no stipules and the leaves of these plants are arranged in two distinct rows along the stem. The leaves are usually smooth and simple. Many species within the family Annonaceae produce highly appreciated fruits, such as Biriba, Cherimoya and Papaw.
