Description and Ethnobotany
| Growth Form | A majestic, solitary, small to medium-sized, under-storey palm bearing large, impressive simple leaves with the blade lanceolate in outline and no visible stem as it is usually underground. |
|---|---|
| Trunk | Trunk acaulescent (stemless or apparently so, or with the stem subterranean) thus usually not visible, solitary, ringed with leaf scars. |
| Foliage | Fronds large, glossy, up to 3.5 m long and 30 cm wide, simple, erect to spreading, lance-shaped with folds, covered with soft, brown scales on the underside, armed with small, sharp teeth along the margins. |
| Others - Plant Morphology | Flower: Inflorescences cream, sessile (attached directly at the base); flowers with tubular, inflated bracts. Fruit: Fruits globose, brown, knobbly, with numerous corky protuberances. |
| Cultivation | It is strictly an under-storey palm and requires filtered light, and a moist and humid environment. Prefers moist, well-drained soils that are fed occasionally. Propagate by seeds. |
| Etymology | Its genus epithet 'Johannesteijamannia' is honoured after Johannes Elias Teijsmann (1808 to 1882), a Dutch gardener and botanist at the formally Buitenzorg Botanical Garden, Java (now Kebun Raya Indonesia, Bogor). Its species epithet 'lanceolata' means 'lance-shaped' in Latin, in reference to the shape of its fronds. |
| Ethnobotanical Uses | Others: The fronds are commonly used for thatch by the natives. |
