IV. CHIRANTHODENDRON SERIES. 
Chiranthodendron (figs. 103-105) has regular hermaphrodite 
apetalous flowers. Upon the depressed receptacle is inserted a 
campanulate, coloured, thick, coriaceous perianth, whose divisions are 
united toward the base, and in the bud are ranged in quincuncial 
præfloration. At the foot of each is found a nectariferous dimple. 
More internally the receptacle bears the gynæceum, and around it 
enveloping it like a sheath the androceum is found, formed of five 
monadelphous stamens alternating with the divisions of the calyx. 
Chiranthodendron platanoides.
