Fig. 2. Schismatoglottis bauensis A.Hay & Chi. C.Lee. A. Plants in habitat on karst limestone formations at the type locality, Gua Peri Peri (Fairy Caves) near Bau, Sarawak. B. Limestone deposits on plant in habitat. Note that the deposits are whitish. It appears that the habitat is not wet enough to allow algae to grow on the leaf surface deposits. C. Inflorescence at pistillate anthesis. D. Detail of the junction of the spathe limb and lower spathe. E. Spadix at pistillate anthesis (spathe artificially removed). F. Inflorescence at staminate anthesis, just after pollen release. Note that the spathe limb has by now been shed. B-F from P.C.Boyce & Wong Sin Yeng AR-2053. All images © Peter C. Boyce.
