It exhibits clustered green stems and pale green petals,with an average of 6.8 flowers per stem. Under a planting density of 45 000 clusters · hm^-2,the average fresh stem yield reaches 1 644.0 kg · hm^-2 from the third year after transplantation. The dried product contains 12.0% extractives,with stem crude polysaccharides,total polysaccharides,and mannose contents of 28.7%,26.3% and 20.6%,respectively. The crude polysaccharide content in fresh and dried flowers is 6.6% and 8.6%,respectively. This cultivar is suitable for cultivation in warm,humid forested areas such as Qianxinan and Qiannan,primarily via epiphytic tree planting. It demonstrates strong stress resistance under natural cultivation conditions,combining high yield with superior quality,making it highly valuable for widespread application.
