]. The stems are collected wherever they occur because of their high economic value. Due to its restricted distribution, production occurs only in a few places and no reliable figures are available on annual output. After harvesting the canes are sold to middlemen and then shipped to manufacturers in cities on the mainland for making furniture and handicrafts[

They have excellent quality and growth form, and a great potential to be planted in subtropical and tropical areas. On a small scale, it can be planted in agroforestry systems as a potential source of income for rural people[

Although seedlings require the support of pre-existing tree crops and forest canopy, they also require adequate sunlight for healthy and fast growth. The annual average growth rate of the stems growing under semi-shade canopy conditions is three times as high as that of stems growing in dense forest. However, young seedlings cannot withstand full sunlight throughout the day as young leaves may become scorched[

On a small scale, seedlings can be planted in scattered clumps in agroforestry systems; on a commercial scale the species can be planted in lines, on a grid of about 4 metres x 5 metres in logged-over forests or in planted broadleaved forests but the forest canopy should be manipulated to allow light to reach the seedlings. Group planting, 2 - 3 seedlings per clump, is considered to be suitable for this species[

It is estimated that 10 - 11 years after establishment the plantation will be ready for initial harvest, with an estimated yield of about 3.5 tonnes per hectare. It is also estimated that within a 25-year management period, canes may be harvested 5 times in a rotation of 5 years, providing a total yield of about 11.5 tonnes per hectare[

Although we have no further specific information for this species, many members of this genus have potentially edible young shoots. Indeed, in Laos the shoots are considered to be a delicacy and over half the species growing there are said to be cooked and eaten as a vegetable. The top 100cm of the plant is used. If the leaf sheaths are left in place until just before cooking then the shoot will remain fresh for up to one week[

The long and slender stems of Calamus species are put to various uses according to their size, length, flexibility, elasticity and toughness. The most slender canes are employed entire for binding purposes, and in making chairs, blinds, mats, wicker or basketwork, fishing implements, etc. Twisted together, they make very strong cables. The largest and more resistent canes are used entire as cables, the framework of wicker chairs etc. Usually, however, for many purposes the stems are split throughout their length into 2 - 4 or more strips from which the inner soft brittle and spongy portion is removed by means of a knife or same other instrument, so as to leave the external portion, which is hard, tough, flexible, elastic and has its outer surface very clean and smooth as if it had been varnished[

Strips vary in width according to the use to which they are to be put. Those for delicate work, such as the network of furniture, small bags, hats, etc, are from 1 - 3mm wide; those employed as lashings in native housebuilding or in fastening the removable head of the Malay axe to its handle are from 5-6 mm wide[

Collecting and preparing the stems is very simple. The stem is cut near the ground and detached from the trees by taking a strong hold of its base and thus pulling down the entire plant with its leaves. The most recent growth at the top of the plant is removed and then, handling it from the upper end, the stem is forcibly drawn in the opposite direction between two pieces of wood, thus removing the spiny coverings. It is then cut into lengths of about 5 metres, each piece is bent into two equal parts and the stems are fastened into bundles ready for market. The most valued stems are not thicker than a man's little finger and have a fine polished straw-yellow glassy surface[

Propagation

Seed - it has a fairly short viability and is best sown as soon as it is ripe. It germinates 5 - 60 days after sowing with a few seeds germinating after 120 days; after 2 - 3 months the seedling-leaf emerges; after 3 years, the first stem may exceed 1 metre in length[

Seed propagation includes removing the fruit wall and fleshy seed-coat, cleaning the seeds, sowing seeds in sand beds for germination, and transporting the sprouted seed (the first foliage leaf unexpanded) in potting bags into a nursery under semi-shade. Seedlings 11 - 15 months old and with 6 - 7 leaves are usually ready for planting out[
