Tengar
Ceriops sp.
Family Rhizophoraceae
updated
Jan 2013
Where seen? Usually neat and tidy trees or bushes. Sometimes seen in our mangroves.
Features: A short tree sometimes
just a bush, older plants may have well developed knee roots. The
leaves are thick and spatula-shaped so they are sometimes mistaken
for Teruntum (Lumnitzera
sp.). Tengar (Ceriops sp.) have a flattened knife-like stipule (leaf bud at the tip of a branch). For young plants, it is difficult to be sure whether they are Tengar putih or Tengar merah without the flowers and propagules. To distinguish from Pisang-pisang (Kandelia candel), Tengar leaf stalks usually not pinkish.
Human
uses: Tengar (Ceriops tagal) is valued as timber,
firewood and a source of dyes. It is also used in traditional medicine.
Status and threats: Tengar putih
(Ceriops tagal) is listed as 'Vulnerable' and Tengar
merah (Ceriops zippeliana) as 'Endangered' on the Red List
of threatened plants of Singapore. |
