IV. TETRANTHERA SERIES. 
Tetranthera’ (figs. 256, 257) has dicecious flowers* The perianth 
has six divisions, and the androceum, sterile in the female flowers, 
consists of from nine to twelve stamens, inserted round the rudi- 
mentary gyneceum, which is sometimes altogether absent. These 
stamens open by four introrse valves.‘ In the female flower is a 
fertile gyneeceum formed of a uniovulate ovary surmounted by a 
style, whose dilated stigmatiferous head is more or less markedly 
lobed.’ The fruit is a one-seeded berry, supported on the shallow 
receptacle which alone persists at its base after the fall of the 
perianth. In certain species we find from twelve to fifteen or 
eighteen fertile stamens, or even from thirty to thirty-six. In this 
case, more than three (sometimes as many as six) may possess two 
basilar lateral glands. In other species the re- 
ceptacle forms a deeper cup with truncate edges, 
and may be deep enough to conceal half the fruit. 
For these species a special genus, Cylicodaphne, 
has been created. Of the true Zetrantheras some 
ninety species are known, trees or shrubs from 
tropical Asia and the neighbouring parts of Oceania; 
and some are Australian or American. Their leaves 
are alternate or rarely opposite, penniveined. The 
flowers. are united in groups of at least four to form 
little pedunculate umbels or capitula, protected by involucres of 
from four to six imbricate bracts. ‘These little inflorescences spring

pores or folds in 7. macrophylla ; and spherical, 
with some. twelve non-granulated spots, in Tomes 
tetranthera, which appears to belong to this 
genus. 
5 The male and female flowers are pretty 
frequently constructed on the 4-type in cul- 
tivated species. This is the case with the one 
whose diagram is given in fig. 257, and which 
had eight perianth-leaves, twelve stamens, all 
introrse, and a sterile ovary.
