Hymenodictyon orixense (syn. Hymenodictyon excelsum) is a species of flowering plant in the family Rubiaceae. It is found in the Indian Subcontinent, south-central China, Mainland Southeast Asia, and the Philippines.

A tree. It loses its leaves during the year. It grows 25 m tall. The bark is smooth and grey. The leaves are often grouped near the ends of branches. The leaves are narrowly oval and 9-22 cm long by 6-14 cm wide. The flowers are near the ends of branches. They are white or brown. The fruit is an oval capsule 2-3 cm long. There are many flat seeds.

Medicinal Uses

The leaves are used medicinally to relieve tooth ache.

Distribution

It is a tropical plant. It grows in forests along rivers between 100-1,700 m above sea level. In Sichuan and Yunnan.

Where It Grows

Asia, Bangladesh, Cambodia, China, Himalayas, India, Indochina, Indonesia, Laos, Malaysia, Myanmar, Nepal, Philippines, SE Asia, Thailand, Vietnam,

Cultivation

Plants can be grown by seeds.

Propagation

Seed - direct seeding is not recommended as the seed is very small (about 170 000 seeds/kg) and easily washed away. The seed usually germinates easily, but loses its viability within a year. It should be sown in seed-beds and lightly covered with fine soil or fine sand and watered frequently, but sparingly. The first seedlings appear after 10 days, when 2 - 3 months old they can be pricked out into containers. The more vigorous seedlings can be planted out after one year, others should be kept in the nursery for another year. Seedlings are light-demanding and easily killed by weeds.

Other Uses

The heartwood is white when fresh, becoming yellow-grey or pale grey-brown on exposure, not clearly demarcated from the sapwood; grain straight; texture moderately fine to slightly coarse and even. The wood is soft to moderately hard and moderately strong. It works very easily and turns well. The wood is not durable when exposed to the weather or in contact with the ground and is moderately resistant to preservative treatment. It is somewhat liable to borers, especially when left debarked. The wood is used locally in house building, e.g. for planks, and sometimes for boats; it is also used for boxes, scabbards, packing-cases, implements, toys and matches. In India it has been recommended for cheaper grades of furniture, warper bobbins and wood-wool board.

Notes

The leaf is used as medicine to relieve tooth ache.
