Khasi papeda
Citrus latipes (Swingle) Tanaka
Description
Khasi papeda (Citrus latipes) is a unique and scientifically significant species within the Rutaceae family. Known for its remarkable resilience, this plant has drawn significant attention from citrus breeders looking to develop cultivars capable of surviving in cooler climates where standard citrus varieties would fail.
The origin of this species is traced to the mountainous regions of Northeast India, particularly the state of Meghalaya. Its native habitat consists of humid subtropical forests at varying elevations, which has naturally selected the plant for tolerance to both moisture and fluctuations in temperature.
Botanically, the Khasi papeda is characterized by its wide, winged petioles and thorny branches. The trees are medium-sized, often reaching several meters in height. The fruits are typically small to medium, with a thick, aromatic rind and highly acidic pulp, containing numerous seeds, which makes them less desirable for fresh consumption but excellent for rootstock development.
Agricultural requirements include well-draining, slightly acidic soil enriched with organic matter. While it is more cold-hardy than many commercial citrus species, it still requires protection from severe frost. Consistent watering is essential, especially during the growth phase, though soil saturation must be avoided to prevent root diseases.
The economic and agricultural utility of Citrus latipes is primarily linked to its role in hybridization programs to improve the hardiness of other citrus fruits. It is also used locally for its essential oils and culinary seasonings. Typical pests include citrus mites and aphids, while root rot remains a concern in poorly drained soils.
