抄録

The author participated in the Nepalese research team sponsored by the Ministry of Education, the Japanese Government in 1975, and was helped by the Department of Agriculture in the Royal Nepal. Anaphalis specimens were collected in the trekking from Kathmandu to the Langtang Valley area of the Himalaya mountain region (Appendix table 1 and 2). Anaphalis A (Fig 1-A), which are highest and have many flowers (average 300), are distributed in 1,000m〜2,000m elevation, the center 1,200m (Fig. 3 and Table 1). Anaphalis B (Fig. 1-B), which are medium high and have many linear leaves with hair cells, occur in 1,500m〜3,500m elevation, the center 2,250m (Fig. 3 and Table 1). Anaphalis C (Fig. 1-C), which are smallest and have a few comparatively big flower (under 30 flowers), grow in 2,000〜3,500m, the center 3,000m (Fig. 3 and Table 1). The species grown in the highest place, have several leaves with many long hair cells and developed the rhizome systems. It is considered that changes of the leaf shapes and its numbers, the existences of hair cells on the leaves, the development of rhizome system and the decrease of flower numbers might originated in the result of adaptation for the cold temperature in the high mountain region.
