This is a family of flowering, fruit-bearing plants. The members of this family are
very cosmopolitan and subsist all over the New, as well as the Old World.
The Annonaceae, or the soursop family, is a flowering family consisting of trees,
shrubs and lianas. The fruits of this family are large, pulpy and edible. Some
family members also produce aromatic oils, which can be used for perfumes or
These plants are rhizomatous or tuberous herbs typically with
calcium oxalate crystals or raphides and a milky sap. Leaves are
usually large, spade-like and have a sheathing base. The flower is
a fleshy spike or spadix partially enveloped by a bract, which is
brightly coloured. The Philodendrons and Monsteras are part of
this family and are popular as ornamentals. They are mostly
Araliaceae is a family of flowering plants, also known as the Aralia family or the
Ginseng family. The family includes trees, shrubs, lianas and herbs. These are
The Asteraceae are herbs, shrubs or less commonly, trees and are perhaps the
largest family of flowering plants. The family Asteraceae is known as the aster or
daisy family. These dicotyledons derive their name from the genus Aster star
shaped flowers of the family’s many daisies.
Species in this family are mostly tropical trees or shrubs. The flowers are usually
large and “showy”. They have a large diversity in the Neotropics. Tabebuia
species are frequently used to line streets and beautify natural areas.
There are three subfamilies of Bromeliaceae: Pitcairnoideae (terrestrial with
pointy leaves), Bromelioideae (terrestrial epiphytic, tanks), and Tillandsioideae
(epiphytes). Pitcairnoideae grow rooted in the soil. The leaves often have spiny
edges, and may be thick and fleshy. The next two subfamilies are considered
more evolved and many are epiphytic, absorbing water through their leaves
This family is also called the incense tree family. The family includes both trees
and shrubs and is native to tropical regions. Some members of the family
produce fragrant resins used as incense or perfume, most notably frankincense
The Clusiaceae are trees or shrubs, usually with milky or colourer sap. The
leaves are simple and are opposite, whorled or rarely alternate and the fruit is
These flowering plants include trees, shrubs and lianas. This family is widely
distributed and is cultivated for ornamentals and for its edible fruits.
This family of plants are the tree ferns, some of which are arboreal. Some
members of this family are very specific to particular habitats.
This is the family of grasses. They are mainly herbaceous, but some members
are woodier for example bamboo. These are entirely monocotyledons and have
a widespread distribution, tolerating many diverse habitat conditions.
The Heliconia family, which is a single genus, is distributed in mainly tropical and
subtropical regions. It is cultivated as an ornamental plant. The defining features
are the highly coloured bracts, which make these species very recognizable.
Also known as, the Barbados-cherry family, this family is very diverse in its family
members. This family comprises of trees and lianas.
This family consists of perennial flowering herbs that grow from rhizomes. The
fruits are fleshy, dry capsules. The family is sometimes called the "prayer-plant
family”. The most famous species in the family is Arrowroot (Maranta arundinacea), a plant of the Caribbean, which is known for its easily digestible
starch. Several species of genus Calathea are grown as houseplants.
This family is a taxon of dicotyledonous flowering plants that is found mostly in
the tropics. They are annual or perennial herbs, shrubs or small trees. A
number of these are considered to be invasive plants.
The Meliaceae, or the Mahogany family, is a flowering plant family of mostly
trees and shrubs, with only a few herbaceous plants. Most of these species are
evergreen, even though there are some species, which show deciduous
behaviour. Species in this family are used for making oil, soaps, insecticides and
The Mimosaceae are mostly tropical and subtropical trees and shrubs. The
arrangements of their leaves are nearly always the same with alternate, stipulate
and bi-pinnately arranged compound leaves.
There is over 1,000 species in the Moraceae family comprising of trees, shrubs
and rarely herbs worldwide. Most have a milky sap. Their leaves are simple and
alternate most of the time. The flowers are unisexual and are densely
The banana family consists of large tree-like perennial herbs, the Musaceae
have alternate leaves with concentric sheathing portions that create pseudo-
trunks from which the blades diverge. The blades have prominent mid-rib and
parallel lateral veins. Members of this family are highly recognisable.
This family is also referred to as the Nutmeg family, as it is named after its most
famous member, Nutmeg (Myristica fragrans). These plants are flowering plants
with several hundred species of trees and shrubs in tropical regions. The best-
known species are those from the genera: Myristica and Virola.
This family consists of trees and shrubs found in the tropics, subtropics and
temperate regions. The leaves are usually opposite and frequently glandular
dotted. Psidium guajava “guava” is a shrub, which is pink or cream inside and
The palms are a highly recognisable family of plants are found widely in tropical
and subtropical habitats. Many species are known to tolerate specific habitats,
while some of which are important to the survival some animal species in
This family of dicotyledonous plants are characterised by their "butterfly-shaped"
flowers, composed of a top petal, the "standard”, followed by two opposing petals
on the sides, the "wings", followed by a bottom petal, the "keel", in which the
reproductive organs are situated. The fruits are pods. This family used to be
called legumes. Some members are cultivated for food, for example chickpeas
Member of the pepper family are fleshy herbs and soft shrubs. The fruit is a
berry or a drupe. The genus, Peperomia is widespread throughout the tropics
and has a distinct candle-like inflorescence.
The ferns are an ancient group of plants which pre-date even earliest dinosaur
fossils. They are leafy plants that grow in moist areas under the forest canopy,
along rivers and streams and other sources of permanent moisture. Ferns are
highly prized ornamental plants in the tropics.
The rose family is a large family of plants, which is typically divided into four
subfamilies: Rosoideae, Spiraeoideae, Maloideae and Amygdaloideae. These
subfamilies are primarily described by the structure of the fruits which they bear.
This is a family consisting mostly of trees and shrubs. The leaves are simple and
entire and usually opposite. The fruit is variable, often forming multiples.
This citrus family is made up of herbs, shrubs and trees with waxy dark green
leaves. The flowers are sweetly scented and self-pollinating; however, bees do
assist with pollination. The fruits are spherical to oblong and the intensity of their
colour depends upon both the climate and the cultivation.
The Sapotaceae or the sapodilla family are trees or shrubs with milky sap, which
is characterised by the presence of reddish-brown hairs on the leaf undersides
and other plant surfaces. The fruit is a berry.
Sterculiaceae or the cacao family are flowering plants. The family name is
derived from the genus Sterculia. The most famous products of the family are
chocolate and cocoa from Theobroma cacao, followed by cola nuts. Many

relationship with the Aztec Ants colony, thus are found in unison. Though this
family of birds enjoys dense vegetation as their habitat, they are found in varied
habitats throughout Trinidad and Tobago.
This is a family of seedeaters that has rare species such as the Red Breasted
Robin. Much of the species is in danger of becoming vulnerable because of
entrapment and the lost of savannah habitats. The family enjoys various types of
habitats, from forest to savannahs, with the majority of species being well
distributed throughout Trinidad and Tobago.
This family is found in a variety of habitats over a wide area. It is an extremely
active and energetic family of birds, as they would cling to vegetation at every
angle in order to forage. They are often hanging upside down to looking for food
This family frequents the undergrowth and low branches in the forest and second growth. They
are small, inconspicuous, wren-like birds with a very long thin bill. They also possess a long
narrow tail, which it flicks loosely as it moves restlessly among the foliage somewhat in a manner
of certain antbirds. They are insectivorous.
These are small and cryptically coloured birds with short rounded wings, stumpy tails and
slender, straight or slightly curved bills. They inhabit undergrowth and low vegetation and are
more commonly heard than seen. They are insectivorous and quite usually forages among the
foliage. They are found in practically all habitats from the residential areas to forested areas.
This family is common known as woodpeckers. These birds live, feed and breed
in trees and can be seen perched vertically on tree trucks foraging for food.
Some of these species have specific habitats, preferring secondary rainforests in
some cases. Some species prefer to inhabit forested areas near residential
areas. This family has a wide range across Trinidad.
These characteristic and recognisable family of birds are nocturnal birds. The bill

They may be found in habitats that range from cleared areas to areas of dense
vegetated areas, where they forage upon flowering shrubs.
These are small to medium size butterflies that inhabit areas with dense
vegetation to forested habitats. They are often over-looked due to their
translucent wings which gives rise to family’s common name ‘Clearwings’. The
family displays a wide distribution throughout Trinidad and Tobago.
