Venus Flytrap – Feed On Insects
Venus flytrap is known as Dionaea
muscipula. It belongs to the kingdom - plantae, phylum – anthophyta, class –
magnoliospdia, order – nepenthales and
family – droseraceae. This is one kind of interesting plant which feed on
insects. Venus flytrap is the carnivorous plant. Initially scientist believed
this plant to be a myth until they found the physical proof for the existence
of such a plant. The plant is innocuous looking rosette. The leaf blades
terminate in distinctive bivalve traps with sharply toothed edges. The length
of the leaf blade is up to 12cm whereas the trap length is upto 4 cm. the trap
of venus flytrap is very powerful as the
ones set by trappers for wolves, bears
etc. it is effective in catching its own small preys.
The leaves of the venus flytrap is open wide and contain stiff hairs on them called trigger
or sensitive hairs. The sensitive hairs at
fold of the leaf prevent them from closing every time when a drop of
rain falls on it because the leave requires two or more of these hairs
triggered in succession. Like other plants venus flytraps gather nutrients form
gases in the air and nutrients in the soil. However they live healthier if they
get nutrients from insects. Insects are attracted to the small traps. On the
inner lobes there are usually three
trigger hair and if an insect lands on lobe and brushes against two of these
hairs the trap with snap partially shut with a speed that amazes onlookers. The teeth
are now interlocked preventing larger prey from escaping . The trap need to close further to produce tight
seal for the prey to be digested.
The outside of the trap is
generally green where as the inner side have
red pigments that varies in shade depending on the age of the trap. Venus
flytrap needs wet roots, poor acidic soil, high humidity and full sunlight to
grow. The recommended soil mixtures is
one that contains sphagnum moss and sand. The plant produces the flowers
in a tall stalk above the leaves. Seeds
produces by the flowers are very tiny. The Venus flytrap is listed as an
endangered species. Venus flytrap is endemic to a restricted area of the Carolina’s
coastal plain including southeastern, North Carolina and northeastern south
Carolina.

Eskimo Curlew (Numenius Borealis)- Shorebird
Eskimo curlew is a small , mostly
brown shore bird. It is a medium sized shorebird with a slender, slightly down curved bill. It is approximately 30 cm tall, has
short bluish gray legs and a rich cinnamon color on its belly and wing linnings.
It belongs to the family Scolopacidae. Eskimo curlews migrate from breeding grounds
in the Arctic tundra through the north American prairies to wintering grounds
on the pakpas grasslands of Argentina. Eskimo curlew’s habitat includes
grasslands, plowed fields, pastures and
mudflats. Eskimo Curlew is close to
being extinct.
The Eskimo curlew eats both plants
and animals. The Eskimo curlew’s diet consist of freshwater insects and the fruit of Black Crowberry. It also eats ants, worms and other
invertebrates found on shores. In the coastal areas they feed on snails and
along the Atlantic coast they eat beetles, spider, moth, seeds and other berries. The Eskimo curlew is endangered
because of unrestricted overhunting for the market, especially during its
northward spring migrations. This bird also has a tame nature and is extremely friend,
making it easy prey for hunters. Eskimo curlew’s nest are just a hole in the
ground. They are lined with decaying leaves and a thin sprinkling o hay. The
eggs have a color similar to that of
surroundings grass, being dark brownish green to blue blotched with brown.
Pothos – Devil’s Ivy
Pothos is one of the
easiest houseplant to grow. Its
botanical name is Epipremnum aureum or Scindapsus aureus. But it is often referred
as devil’s ivy or variegated philodendron. These plants can do well in indirect
lights. One of the special features of this plant is that it can be grown both
in water or in dry soil. Pothos are incredibly easy to root from cuttings. A part
of of mother plant can be cut and rooted
in water . pothos also be grown in soil . they will thrive well in nutrient rich
soil but do almost in nutrient poor soil
as well.
The natural form of Pothos is a
trailing vine. Fluorescent light is acceptable as a light source. Its leaves
are pointed heart shaped and can be green or variegated in white, yellow or a
paler green. The leaf sizes vary with varieties and growing condition as well. The
one that I had is green with white combination. I consider them as a best
decorative plant as I can decorate the windows with them. The climbing/trailing
habit makes them extremely decorative .Pothos plants prefer to dry out between watering.
Pothos are poisonous too. The plant can cause
irritation and vomiting if ingested due to the fact that it contains calcium
oxalates. It is considered toxic to cats, dogs and children. It makes them very
sick.
Portulaca Grandiflora – Sun lovers
Portulaca Grandiflora is one of my favorite plant which doesn’t need any special care and
brings the beauty to our garden with its different colors of flowers. It
belongs to the family Portulacaceae. It is commonly known as portulaca, moss
rose, rose moss and sun plant. Portuclaca flowers tolerate many kinds of soils but prefer sandy well drained soils and love
the full bright sunlight. These plants will spread themselves very well. You do
not need to water often for proper portulaca care. The cylindrical foliage
of portulaca flower retains moisture
very well.
The flowers are borne on the stem
tips. They open only during bright sunlight and closes at night and on cloudy
days. There are many varieties with different colors of flowers such as orange,
rose pink, red, yellow, white. The one which attracts me is white and rose pink with its natural beauty. Moss rose
makes a beautiful ground cover in a dry
or rocky area. In warm climates moss rose may self seed. Its reddish
brown like stems and bright green leaves are thick , soft and juicy.
Easily propagated by pinching off the stems of
this plant into 2-4 inches length and stick them directly into moist sand or
loamy soil and locate it in a sunny area. Portulaca can also be propagated from
seeds that are as tiny as dust. Portulaca are originally from the hot, dry
plains of Southern Brazil, Northern Argentina,
Uruguay.
