Background : This text was conducted to evaluate the distribution, shape characteristics and habitat condition of Crypsinus hastatus in Buyeo Korea. Methods and Results : In Buyeo, Crypsinus hastatus was distributed at an altitude of 31.2 m, a slope of 82.5% and a distance from river water of 27.2 m. The leaf blade was oblong, 2.7 ㎝ long, 1.2 ㎝ wide with a petiole length of 2.3 ㎝. The total population comprised 2,100 individuals, with the highest proportion being individuals with a leaf blade of length 0.5 - 1 ㎝. The temperature and light intensity of the growth point were lower, but the humidity higher, than that of growth around. The chemical properties of the soil were as follows: pH 4.42, organic matter 77.99 g/㎏, electrical conductivity 0.50 dS/m, nitrate nitrogen 20.50 ㎎/㎏ and available phosphate 165.7 ㎎/㎏. Exchangeable cation content of potassium, magnesium, sodium and calcium was 0.35, 0.70, 0.09 and 2.04 c㏖+/㎏, respectively. Conclusions : In Buyeo, Crypsinus hastatus was distributed in 5.3 ㎡ area of Nakhwaam, Naeseongri and Jeongamri. However, the population of the medicinal resources seemed to decrease owing to the poor environmental conditions of the habitat.
