Description
D. Regia is a tall tree achieving a peak of extra than 15 m and a girth of 2 m. under favourable conditions. The bole is brief. The trunk is buttressed and the stem form above the buttress is normally ordinary in taper. The trees are nearly evergreen, with huge-spreading, open, umbrella-formed crowns.

They are inexperienced and flaccid whilst younger and are compressed, firm and alternatively thick when mature. Seeds are massive, yellowish, rectangular, arranged at right angles to the period of pod and transversely mottled. The seeds have a difficult, bony testa.
Plant Cultivation
A plant of low to medium elevations inside the moist tropics, being found at elevations from sea degree to 2,000 metres. It grows in regions in which the mean annual temperature ranges from 14 – 26°c. The mean annual rainfall is over seven-hundred mm. It can achieve regions with both excessive and scanty rainfall. Trees can develop at better altitudes than recommended, however flowering turns into erratic.
The species appears to tolerate many types of soils from clay to sandy. However it prefers sandy soils. Prefers a pH within the variety five. 5 – 6.5, tolerating 4.5 – 7.5. Established flora are very drought tolerant. Trees starts flowering in their 4th or fifth years. In wet places, the tree starts to develop young foliage earlier than the flowering season and does no longer flower prolifically. It additionally plant life much less prolifically on the shady sites than on the sunny websites. Planting of timber on dry sites therefore promotes copious flowering.
Uses
We’ve visible no reviews that the mature seeds of this plant are eaten. Research has shown that they may be a potential nutritious food for humans. They incorporate around 48% carbohydrate, 8.7% protein and 17.2% fats, plus a great variety of minerals. Although alternatively excessive in sodium. Antinutritional compounds which includes tannins, saponins and oxalates are present, but in decrease concentrations than in many usually eaten meals. The sodium to potassium ratio is as an alternative high and will cause coronary heart issues in later life. If the seed becomes a prime part of the food regimen – although eating the seeds with foods wealthy in potassium and coffee in sodium could restore a stability. The seed includes round 17.2% of a candy-smelling, amber-coloured oil.
The tree yields a thick mucilage of gum, produced in yellowish or reddish-brown warty tears. The gum is soluble in water, forming a thick opalescent mucilage. It carries a big amount of calcium oxalate.The seeds incorporate round 17.2% oil. This oil includes regular glycerides, low unsaturation and could be very good for the production of soaps and shampoos.
Propagation
Seed – has a hard, woody testa and takes a long term to germinate. It may also lie for two – 3 years within the soil with out germinating and typically take 12 – 349 days to germinate. Alternatively, pour a small amount of just about boiling water over the seed. Ensuring it cools down earlier than the seed is cooked, then soak the seed for 12 – 24 hours in heat water previous to sowing.
After treated seeds are sown in unshaded nursery beds, they germinate within five – 10 days, with a germination charge of up to 90%. Seeds may be stored for a long time if insect attack is averted, which may be finished through adding ash to the seeds. Seed storage behaviour is orthodox and a germination price of 47% has been recorded after 9 years of storage at room temperature; and not using a loss in viability following 4 years of storage.
