摘要
Trichome forms and stomatal distribution and types were undertaken. The results show that trichome forms are stellate, peltate and stellate-peltate. There is a difference in the position of stomata among the taxa of Hippophae. H. thibetana, H. salici-folia. H. gyantsensis, H. neurocarpa and H. rhamnoides ssp. turkestanica have stomata on both foliar surfaces, while other subspecies have stomata only on the lower surface. Stomata are of the Actinocytic type.
