Comparative Vegetative Anatomy And Systematics Of The Angraecoids (Vandeae, Orchidaceae) With An Emphasis On The Leafless Habit, Barbara S. Carlsward, William Louis Stern, Benny Bytebier
Comparative Vegetative Anatomy And Systematics Of The Angraecoids (Vandeae, Orchidaceae) With An Emphasis On The Leafless Habit, Barbara S. Carlsward, William Louis Stern, Benny Bytebier
Faculty Research & Creative Activity
The vegetative anatomy and morphology of 142 species of the angraecoid orchids (Angraecinae + Aerangidinae) and 18 species of Aeridinae were examined using light and scanning electron microscopy. Leafless members of Vandeae were of particular interest because of their unique growth habit. Leafy and leafless members of Angraecinae and Aerangidinae were examined and compared with specimens of Aeridinae. Vandeae were homogeneous in both leaf and root anatomy. A foliar hypodermis and fibre bundles were generally absent. Stegmata with spherical silica bodies were found associated with sclerenchyma and restricted to leaves in almost all specimens examined. Distinct inner tangential wall thickenings …
