Mimosa pudica (Sensitive Plant)
My recent trip to Gunung Keriang Recreation Park Gunung means a small hill) allowed me to discover a few interesting plants. one of them is this mimosa pudica that grows on rock. it creeps and the roots clasped the crevices in the rock. It thrived well.

Mimosa pudica (Sensitive Plant) (pudica = shy), is a creeping annual or perennial herb often grown for its curiosity value: the compound leaves fold inward and droop when touched, re-opening within minutes. The species is native to South America and Central America, but is now a pantropical weed.

Mimosa pudica (Sensitive Plant) (pudica = shy), is a creeping annual or perennial herb often grown for its curiosity value: the compound leaves fold inward and droop when touched, re-opening within minutes. The species is native to South America and Central America, but is now a pantropical weed.

The stem is erect in young plants, but becomes creeping or trailing with age. The stem is slender, branching, and sparsely to densely prickly, growing to a length of 1.5 m (5 ft). The leaves are bipinnately compound, with one or two pinnae pairs, and 10-26 leaflets per pinna. The petioles are also prickly. Pedunculate (stalked) pale pink or purple flower heads arise from the leaf axils. The globose to ovoid heads are 8-10 mm in diameter (excluding the stamens). On close examination, it is seen that the floret petals are red in their upper part and the filaments are pink to lavender. The fruit consists of clusters of 2-8 pods from 1-2 cm long each, these prickly on the margins. The pods break into 2-5 segments and contain pale brown seeds some 2.5 mm long. The flowers are pollinated by the wind and insects.

Plant movement
Mimosa pudica is well known for its rapid plant movement. In the evening the leaflets will fold together and the whole leaf droops downward. It then re-opens at sunrise. This type of motion has been termed nyctinastic movement. The leaves also close up under various other stimuli, such as touching, warming, or shaking. The stimulus can also be transmitted to neighbouring leaves. These types of movements have been termed seismonastic movements. The movement is caused by "a rapid loss of pressure in strategically situated cells that cause the leaves to droop right before one’s eyes". This characteristic is quite common within the Mimosaceae family..

Hello Foozi,
Very fine colours and interesting compositon for this picture of Mimosa pudica. You succeeded to have all four flowers in focus and the sharpness is good too. I looked at your gallery and can see that you have a good eye for composition and colours, the sharpness lacks sometimes, but it improves at every picture. I think that you will become a good photographer once the technique is better known.
Thanks also for the note
Best regards
Anne

Bonjour Foozi,
Splendide macro bien composée et dans laquelle le sujet est bien valorisé par la finesse des détails, la délicatesse des couleurs et une excellente opposition sur l'arrière plan.
A bientôt sur TN pour de nouvelles aventures.

Hello Foozi,
A delightful capture of the flowers of this escape to the tropics of the whole world from S. America. I have seen the Mimosa in Trinidad and Tobago.
The flowers are sharp, stand out well against the BG, and the shot is well composed.
TFS this beauty,
Ivan
