Abstract

|
We have studied epidermis and seeds on twelve species of violets and have found the following diffeences in characteristics; Epidermis are variable among the taxa. stomata are present at both surfaces of leaf blades on the taxa viola grypaceras, V.lactiflora, V.mandshurica, V. raddeana, V. seoulensis, V. takesimana, V. variegata and V. verecunda, while stomata are absent at adaxial surfaces of leaf blades on V. seoulensis and lactiflora are larger than the other taxa. Both taxa are shown as 48 chromosomes in somatic cells intead of the 24 or less chromosomes of the other taxa (1967). In general, call walls of abaxial surface are more waved than the adaxial. Seed size is variable even in the same taxa. The plants, Viola rossii and. V. aldida produce considerablly large seeds (Table 2.) Small seeds are shown by the taxa of V. grypoceras. Color differences of seeds are also shown by the taxa, as dark brown, dark gray and yellew brown The characteristics of epidermis and seed size and color are considered as very useful characteristics for the Viola identificiation and classification.
