Mistletoe

Tapinanthus-infested tree

Tapinanthus flowers

Common names: 

Vernacular names do exist but have not yet been recorded. 

Pest status:

The pest status is unknown. In most cases, the host tree does not seem to suffer but occasionally a tree is found to be so infested with Tapinanthus that it somehow must affect the production. 

Host plants:

Tapinanthus infests a large number of tree species in northern Namibia. It is known from Marula trees (Sclerocarya birrea) and common on Camel's Thorn (Acacia erioloba). There are also observations from Citrus and Combretum species in Oshakati-Ongwediva area. The "Waterberg Flora" mentions Albizia, Acacia, Aloe, Combretum, Commiphora, Euclea, Ficus, Grewia, Rhus, Terminaliaand Ziziphus as host plants.

Distribution:

Widespread and very common in North Central Namibia

Description:

Parasite (a Mistetoe) on trees. The elliptic leaves resemble the olive leaves and gave the species its name  The unopened flowers look like a bundle of vertical matches - red with a whitish tip. The fruit is a red berry, about 1.5 cm long.

Tapinanthus is often overlooked in a tree as it blends in well with the leaves of the tree itself. The dropping of flowers and red fruits, however, leave a tell-tale sign of its presence under nearly every tree. The parasite is best observed during winter time when trees have few leaves and Tapinanthus still have lush green leaves.

Control:

No control is recommended at present

Other notes:

There is a traditional story in northern Namibia about Tapinanthus: The plant is called bird-lime because the pulp of the berry is so sticky that it is smeared onto branches near water holes. Birds resting there will get caught by the glue and can easily be caught.

The woody infestation points of old Tapinanthus specimens are very beautiful. They are often used in decorations and are called "woodroses".

At least one other species of Tapinanthus is found in the area: T. glaucocarpus. It should be recognised on a lot of dense hairs.
