The characteristic of clonal plant, Potentilla anserina were studied in alpine Kobresia humilis meadow by investigation and statistics in this paper.The results are as followed. P.anserina with one stolon is the most and its proportion is 52.86%.The proportion of P.anserina with four stolons is only 4.29%.The ramet number,spacer number,total stolon length and specific stolon internode weight are decreased with the increase of stolon number in P. anserina clone.The second or third ramet are always the highest and the end ramet is higher.The second,third or fourth spacer are the longest and the end spacer is loner while the first one is always the shortest.The total dry weight of the clone is increased slowly while the dry weight proportion of stolons and ramets for reproduction are increased with the increase of stolon number in P.anserina clone.
