Vivipary in Cryptovivipary in Aegiceras corniculatum Difficulties arise from the fact that the mangrove environment, although unique, is so only by a set of factors and not just one. Vivipary or cryptovivipary is not found in any halophytes plants which grow in saline environments or freshwater swamp forest species so indicating that these conditions do not arise from salinity or wet soil conditions.

One suggestion has been that the mangrove presents relatively unstable conditions so having propagules which can grow practically immediately is an advantage. For instance, it is easy to observe that the seedlings of Rhizophoraceae can often plant themselves directly below the parent tree because the centre of gravity is close to the root tip.

However, this is of little advantage to the plant in the long run as the seedlings would be competing with the parent tree for light, nutrients, etc.

Most such seedlings do not plant themselves, but float away and can tolerate immersion for weeks. However, on landing on a suitable substrate, the seedlings can firmly root themselves within days and grow rapidly. Other adaptations to cope in mangroves.

Bruguiera gymnorhiza

Bruguiera gymnorhiza can be cultivated easily under simple growing conditions. We recommend Mangrove Mud Special with which we have excellent results in growing Bruguiera gymnorhiza. Mangrove Mud Special is a long term fertilizer that can be used pure or stretched with sand. The less stretched Mangrove Mud Special is the more effective it is and the easier it is to cultivate Bruguiera gymnorhiza. Humidity Humidity should be around a minimum of 50 percent. The higher humidity is the better it is for Bruguiera gymnorhiza and its growth.

Bruguiera cylindrica

The bark is smooth and grey, with corky raised patches containing lenticels which are used in gas exchange and the trunk is buttressed by roots. The aerial roots or pneumatophores project from the soil in knee-shaped loops and have many lenticels which allow air into the interconnecting roots while excluding water. The roots spread out widely to provide stability in the waterlogged soil. The glossy green leaves are opposite, simple and elliptical with pointed ends. The flowers are in small bunches of in the axils of the leaves.

Bruguiera Cylindrica (Bakau Putih)

This tree grows up to a height of 23m. The base has short angled buttresses and the roots project above the ground to form knee roots. These knee roots have lenticels which allow gaseous exchange in the oxygen-poor and often waterlogged soil. The roots spread over a wide area to help stabilise the tree on the unstable ground. This tree relies on its roots to exclude salt from entering the plant through a process called ultrafiltration. The leaves are arranged in pairs at right angles to each other. The flowers grow in groupings of , usually 3.
