Cassytlia consists of herbs resembUng Dodder in habit (fig. 64), having slender cyhndrical stems attached by suckers to their host-plant: leaves are absent or scale-hke. The small fiowers are generally collected in heads or spicate, having three sepals, three petals. 3 — 3 — 3 stamens and an inner whorl of three staminodes, as usual in the family. The petals are much larger than the sepals. The perianth- tube is Httle developed in the flower but increases consider- abh' in the fruit forming a succulent outer covering. The 40 genera contain about 1000 .species; the}^ are common forest-trees in tropical Asia and America. There seem to be two main centres of distribution: one is in tropical south-eastern.
