Abstract
Morphological, anatomical and molecular characters of 31 taxa of Amaryllidaceae sensu lato (s.l.) representing 29 species and two varieties were investigated. The foregoing data estimated based on the differences among the studied taxa in the morphological characters viz. whole plant, habit, root, stem, leaf, inflorescence, flowers, fruit and pollen grains characters in addition to the anatomical traits viz. root, stem, leaf, scape, a portion of the middle lamina characters and lamina epidermal characteristics and molecular characters viz. start codon targeted (SCoT) polymorphism using the polymorphic information content (PIC) and the similarity distance among the studied taxa (Dice′s coefficient: DC). The data were numerically analyzed using NTSYS-pc program (version 2.02) (Rohlf, 2005) and the principle component analysis (PCA) (Dice, 1945; Sneath & Sokal, 1973).
The main objective of the current investigation is interpreting the similarities and dissimilarities among the studied taxa to facilitate the separation and support the systematic position of these taxa within their specific categories. The conclusion of the study supports the separation of the examined taxa in two separate families; family Agavaceae which include the genera Agave and Furcraea and family Amaryllidaceae which divided into three subfamilies; Hypoxidoideae, Amaryllidoideae and Allioideae. Moreover, this study supports the transferance of Molineria capitulata from family Hypoxidaceae to
subfamily Hypoxidoideae under family Amaryllidaceae and also, does not support the grouping of Agave polianthes in family Agavaceae and confirms returning the species name to Polianthes tuberosa. However, the present study confirms the inclusion of Allium species and Tulbaghia violacea in tribe Allieae of subfamily Allioideae and Agapanthus africanus in subfamily Agapanthoideae in the family Amaryllidaceae.
