6. EVOLVULUS L. (1762) 391

Note — Van Ooststroom (1934) has recognised 15 different varieties of Evolvulus alsinoides , the boundaries of which are far from clear-cut. The three varieties existing in Timor are not always easy to separate, and some transitional forms seem to occur, as Van Ooststroom himself observed (Van Ooststroom & Hoogland 1953).
