  • K. angustifolia is vegetatively very similar to K. cheb and K. scortechinii, and in leaflet shape is perhaps intermediate between the two; it is, however, ecologically quite isolated, K. cheb and K. scortechinii both being plants of lowland and hill Dipterocarp forest. K. scortechinii, besides being Malayan rather than Bornean, has ocreas bearing numerous short triangular spines. K. cheb has distinctly broader leaflets than in K. angustifolia, and its ocrea is of a much stiffer texture. However, the only clear cut vegetative difference is the abundance of floccose white indumentum with black scales on the young ocreas of K. angustifolia as opposed to the absence of floccose white indumentum and presence of black scales in K. cheb. Unfortunately, there is still very little herbarium material of K. cheb and K. angustifolia. (J. Dransfield, A Synopsis of the Genus Korthalsia (Palmae: Lepidocaryoideae). 1981)A
