Description

Myrothamnus flabellifolius is a small resinous shut that grow to be about .2- 1.2m in height. It can be found in either single bundles or colonies. These colonies are commonly found to have extensive root systems. During the winter these plants are known to lose all of their leaves. It will stay in this state for approximately half of the year. After first rainfall, it can grow back its leaves very quickly. These plants were shown to have a noticeable difference in size, between its dehydrated state and re-hydrated state.

M. flabellifolius undergoes a rapid transformation after rainfall, changing from a metabolically inactive state. It can also maintain all its photosynthetic apparatus and chlorophyll throughout all phases of life. The plant is also able to fold its leaf and stems, to reduce the level of light being absorbed by the plant. Thylakoid membranes are stacked upon each other to reduce photo-oxidative stress. Most of the mesophyll cells fold their cell wall in response to desiccation. Sclerenchyma and vascular cells do not fold, providing support for the plant. Once water is re-introduced, water absorption happens mostly via the roots, as leaves are unable to absorb any water at all. Water transport is aided with the help lipids found in the xylem. The lipids help prevents cavitation which helps in re-hydration.

Taxonomy

This plant was first found by Friedrich Welwitschs in 1859.

Environment

Myrothamnus flabellifoliusis is a geophyte that can be found growing along mountain formations in central and southern Africa. It is typically found growing in altitudes between 500 and 1900m. Regions are characterized by high light intensity and, extreme temperature changes between night and day. Winters are normally dry and summer is normally when rainfalls, however the lengths of these period can change drastically from region to region. It can be found in shallow rocky outcrops with soil depths of around 15 cm. It roots will expand to intercept water found in the hollows spaces between the rock. Erosion debris is typically found surrounding its root system.

Cultural Uses

Myrothamnus flabellifolius has been called the resurrection plant because of the its ability to produce flowers after months of dormancy. For this reason, it has been known as a symbol of hope in African culture. Its leaves and stems are commonly used as tea and spices. Leaves can used to make lotion.

Medical Uses

When smoked, it has been know to help with symptoms of depression and chest pains. Leaves can be masticated to help with symptoms of halitosis and gingivitis.
