FRUIT MORPHOLOGY OF GENUS PIMPINELLA L. (APIACEAE) IN TURKEY
Yeter Yeşil
Abstract
Pimpinella L. is one of the most complex genera in family Apiaceae that represented by 31 taxa (26 species and 8 endemic) in Turkey. In this study, fruit characteristics of 25 Turkish Pimpinella taxa were examined by using light and scanning electron microscopy. Considerably different types of fruit shapes and fruit surfaces at species and subspecies level and similarities between related taxa were observed. Fruit shapes of Turkish Pimpinella taxa have a range of shapes such as oblong-cylindrical, oblong, elliptic, ovoide-subglobose oblong-ovoid, ovate, ovoide-globose and subglobose. When the fruit indumentum is examined, the results are found as pubescens, strigose, rarely hispid, hispid, hispid-hamate, hamate trichomes or sometimes glabrous. On the other hand, the study included the fruit surface analysis of nine different ornamentation patterns such as; smoothe-rugose, rugose, rugulose, rugose reticulate, rugose-striate, striate, striate ruminate, and smooth-rugose. Furthermore, the fruit morphology and the most commonly used morphological features of whole plant parts of the studied taxa were examined through a qualitative analysis. As a result of the analysis, the Turkish Pimpinella species were categorized into two groups; such as Group A and B. Group A consisted of only white flowering species and the Group B indicated complexity in its kind. Therefore, Group B was divided into 2 subgroups, namely; Subgroup I and Subgroup II. Consequently, the study highlighted the facts that fruit morphological characteristics can provide valuable insight in addition to taxonomical criteria for the delimitation of infra-generic groups of species.
