This paper made a systematic research on Lonicerafulvotomentosa Hsu et S.C. Cheng, which grows well inkarst areas, from its biological characteristics, such asmorphology, growth and physiology. The main conclusions asfollows:(1)From the viewpoint of morphological anatomy, it hastypical xerophyte structures such as well-developed epidermisand tissues that transport water effectively, small leaf area,dense floss under the leaf surface, high stoma density, thesmall opening degree, thick cuticle, well-developed xylem andpalisade tissues, etc. The pollen of L. fulvotomentosa isseems to be spherical, and has 3 grooves, much bulge on theepidermis evenly. The shape of pollen is an important featureon taxonomy. The ripe fruit has from 1 to 18 seeds, some fruitbranch has 135 berry, its diameter is up to 0.8 centimeter.(2)From the viewpoint of growth, L.
