Ochlandra scriptoria

Ochlandra sciptoria commonly known as Patching bans in Hindi, Kachur in Bengali, Boro bans in Assamese, and Kachur in Marathi, is a clumping bamboo species native to India, especially in Assam, West Bengal, Bihar, and parts of Bangladesh. It thrives in tropical and subtropical forests, typically found in lowland and riverine areas, at altitudes ranging from 300 to 1,200 meters above sea level. Ochlandra scriptoria prefers fertile, well-drained soils with moderate moisture content and tolerates a variety of soil types, with a preference for slightly acidic to neutral conditions.

This bamboo species has a dense growth habit, with culms reaching heights of 3 to 8 meters and diameters of 2 to 4 cm. The culms are greenish-yellow to light brown in color, and the internode length ranges from 20 to 40 cm. The culm sheaths are green when young and turn yellowish with age. The adaxial surface of the sheaths is glabrous, while the abaxial surface is covered with soft hairs. The margins of the sheaths are ciliate.

The leaves of Ochlandra scriptoria are lanceolate to elliptic in shape with pointed tips. The leaves measure 15 to 25 cm in length and 2 to 4 cm in width, with a smooth to slightly rough surface texture.

The inflorescence of Ochlandra scriptoria consists of dense, elongated panicles with multiple spikelets. The flowering glumes are small, ovate, glabrous, and have prominent veins. The stamens are short, exserted, and have glabrous anthers. The bamboo has a long flowering cycle, blooming once every 30 to 50 years. Flowering has been reported sporadically in Assam, West Bengal, and Bangladesh. The bamboo produces small seeds, which are dispersed by wind, although seed germination is slow and requires high humidity.

Propagation of Ochlandra scriptoria is most commonly done through culm cuttings, where mature culms are planted to sprout new shoots. Clumps can also be divided and transplanted to establish new plants. Seed germination is a less commonly used method due to its slow germination rates.

This bamboo species is widely used in various applications, including crafting and furniture, where it is used to make baskets, mats, and furniture. It is also suitable for construction, especially for light construction and scaffolding. Additionally, Ochlandra scriptoria is used in the pulp and paper industry and for making edible young tender shoots, which are consumed as a vegetable in certain regions.

In summary, Ochlandra scriptoria is a versatile bamboo species with applications in crafting, construction, paper production, and as a food source. Its slow-growing nature and long flowering cycle make it a unique species within the bamboo family.
