Stem has 4 corners with fins, climbing to the right, not spiny but sometimes rough or speckled at the base and green or purplish in color.

Leaves are ovate or heart or arrow-shaped or lance-shaped, single, alternate at the base, opposite at the top, bright green or often slightly purplish, 15-20 cm long and 10-15 cm wide.

Tubers and young leaves are cooked in various ways as food ingredients. The tubers can be processed as flour or thin pieces or for the manufacture of alcohol. Cultivars with purple tubers are used in making ice cream and candy. The tubers have a bland taste with a fluffier texture.

Swietenia mahagoni and Swietenia macrophylla, the differences

SPECIES HEAD TO HEAD - To date, mahogany ( Swietenia Jacq.) is recorded as having four species: West Indian mahogany or small-leaved mahogany ( Swietenia mahagoni (L.) Jacq.), big-leaf mahogany ( Swietenia macrophylla King), Honduran mahogany ( Swietenia humilis Zucc.) and Swietenia × aubrevilleana Stehlé & Cusin. The debate over the number of taxa in the genus is still not resolved. Some researchers believe that there are only two species: S. mahagoni and S. macrophylla . I agree with that opinion and the two species can only be differentiated by the size of the leaves. All species in this genus have similar morphology except for leaf size. The following is the key to identifying these two species. S. mahagoni has a stalk length of around 37 cm with 5-6 pairs of strands. The strands are about 10 cm long and about 3.5 cm wide. S. macrophylla has a stalk length of up to 45 cm with 4-5 pairs of strands. The strands are up to 31 cm long and up to 8 cm wide. By Aryo Bando...
