A study was conducted to examine the distribution pattern of four rhizomatous medicinal and aromatic plant species (MAPs) viz., Angelica glauca, Pleurospermum angelicoides, Rheum emodi and Arne- bia benthamii in different forest stands in Central Himalaya. Results show that A. Glauca and P. Angelicoides had a higher (50％) frequency at Chipkoan, Garpak and Phagati forest, R. Emodi had a higher (60％) fre- quency at Rishikund, Suki and Himtoli, and A. Benthamii had a higher (70％) frequency at Suki and Khambdhar The densities of A. Glauca (0.6 plants·m<'-2>) and P. Angelicoides (0.5 plants·m<'-2>) were higher at Chipkoan and Garpak sites than at other micro-sites, while densities of R. Emodi (0.8 plants·m<'-2>) and A. Benthamii (1.0 plants·m<'-2>) were higher at Suki and Khambdhar sites. A. Glauca had highest total basal covers (TBC) (1.2 cm<'2>·m<'-2>) at Chipkoan, P. Angelicoides had highest TBC (0.92 cm<'2>·m<'-2>) at Lati kharak site, A. Benthamii had the highest TBC (6.48 cm<'2>·m<'-2>) at Khambdhar, and R. Emodi had highest TBC (4.53 cm<'2>·m<'-2>) at Rishikund. For the four studied species, A. Glauca showed a contagious distribution, P. Angelicoides and R. Emodi showed the random and A. Benthamii showed the regular type of distribution.
