Abstract: This paper reports epidermal features of leaves in Ophiopogonoideae. Thirty-nine species and one variety (29 species, 1 variety in Ophiopogon, 6 species in Liriope, 4 species in Peliosanthes)were examined under scanning electron microscope. In addition, transections of stomatal apparatuses of six species (Ophiopogon: 3 species; Liriope: 2 species; Peliosanthes: 1 species) were made and examined under light microscope. The stomatal apparatus in Liriope, Ophiopogon and Peliosanthes is of the anomocytic type. These types of epidermal features of leaves in these genera are recognized: Cuticular processes type, No cuticular processes type and No stomatal band type. The cuticular processes type can be further divided into three patterns: Fibrillose, Massive and Wrinkled-massive. The  taxonomic  value  of the  epidermal  features  of leaves  in Ophiopogonoideae is rather evident. (1)These epidermal features can be used to distinguish among those species of Ophiopogon, Liriope and Peliosanthes, even in their vegetative state; (2) The different patterns of cuticular processes are helpful to reasonable classification of some species in Ophiopogon, (3)They are of great value for recognizing some sections, (4) These epidermal features of leaves also provide evidence for further discussion on relation- ships among Ophiopogon, Liriope, and Peliosanthes. The evolutionary trend of the epidermal features of leaves in Ophiopogonoideae is No stomatal band type→No cuticular process type(stomatal band)→Cuticular process type (stomatal band).  According to the epidermal features of leaves, flowers and fruits, Ophiopogon, Liriope and  Peliosanthes are closely related, forming a subfamily Ophiopogonoideae.  Ophiopogon is more close to Liriope than to Peliosanthes, and they should be grouped into the same tribe-Ophiopogoneae. Liriope seems to be more prim- itive than Ophiopogon. Peliosanthes, which constitutes another tribe of its own- Peliosantheae, is more advanced than Ophiopogon and Liriope, and it might have beenderived from its ancestor early.Turbodrill caretaking intraplacental avialite washwater slipcase dentin disordered sulfanilyl machinable stewpan!
