Description – Pride of Burma

This stunning tree is the only member of the genusAmherstia (3). The extravagant flowers are seen hanging from the long inflorescence, or flower stalk, which is a bright crimson red at the end (2). There are 5 petals although 2 of these are minute and the rest are of unequal size. The petals are also crimson; the two medium sized petals are yellow at the tip and the largest petal is broad and fan-shaped with a wavy upper margin and a yellow triangle of colour extending from the lip down into the flower (3). This large petal may be 7.5 centimetres long and over 4 centimetres wide at the end (2). There are either 9 or 10 stamens, 9 of which are partially fused into a pink sheath; the stamens are of two differing lengths with the longer ones having larger anthers(3). The compound leaves bear 6 - 8 large leaflets; these are broadly oblong in shape and are a whitish colour underneath (2). The fruits, or seedpods, are 11 to 20 centimetres long (4). They are roughly scimitar-shaped and the woody outer case opens to disperse the seeds (3).

Glossary

  • Anther: part of the stamen (the male reproductive organ of a flower) that produces pollen. (See http://www.rbgkew.org.uk/ksheets/pdfs/flower.pdf for a fact sheet on flower structure)
  • Endemic: a species or taxonomic group that is only found in one particular country or geographic area.
  • Genus: a category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.
  • Inflorescence: the reproductive shoot of the plant, which bears flowers (See http://www.rbgkew.org.uk/ksheets/pdfs/flower.pdf for a fact sheet on flower structure)
  • Leaflets: the individual 'leaf-like' parts of a compound leaf.
  • Stamens: the male reproductive organ of a flower, it is made up of an anther (the pollen-producing organ) and a filament (stalk). (See http://www.rbgkew.org.uk/ksheets/pdfs/flower.pdf for a fact sheet on flower structure).
