Tridax daisy (Tridax procumbens)

Gletang or tridax daisy (Tridax procumbens) is a plant species in Asteraceae, annual with spear roots, at first lying down then standing up to 80 cm high, branching since at the base and growing wild in many places that are dry and sunny.

T. procumbens has a tube stem, green or purplish in color and long white hair. The leaves are facing, stemmed, elongated round, 2.5-6 cm long, 2-4.5 cm wide, rough-jagged to pinched, succulent, green and hairy.

Compound flowers in terminal humps, 2x1 cm, and long stems. Bell shaped bandage. Females as 5-6 edge flowers with oval-wide tongue, 3-4 wings and white or pale yellow. The flowers of the discs have a large, dense crowding, hermaphroditus, bright yellow crown and yellow stamens.

Hard fruit has corners, 2 mm thick, dark brown or black, tight hair with 15-20 pappus that are feather-like, strong and pointy. The seeds are spread by various butterflies and winds, quickly becoming weeds but not a serious problem.

Tridax daisy grows on dry soil, lots of sun or little shade, especially on sandy and rocky soils, grass fields, dry rice fields, curb or railroad, river banks, sand dunes and abandoned lands on the coast to altitude of 1,500 m.

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...
