Fruit and Seed. The carpels vary from one to four, but 

 three is the most common number. There are usually two in 

 the species of Acer and Negundo, although three occasionally 

 occur. In Dodonsea there are five or six. Dobinea is a re- 

 markable exception, inasmuch as the ovary consists of a single 

 carpel with a solitary erect ovule. In other cases the carpels 

 are united to form an ovary of many cells with axile placentas, 

 or the ovary may be deeply lobed, sometimes divided to the 

 base into as many lobes as carpels, arranged excentrically 

 around a gynobasic style, as occurs in some Ochnaceae and 

 Phytolaccacese. The ovules are one or two, rarely more, 

 in each cell, anatropous, campylotropous, or amphitropous, 

 attached to an axile placenta, and ascending with a ventral 

 raphe and inferior micropyle. They are very rarely horizontal 

 and numerous, or inverted. The fruit contains as many cells 

 as there were carpels in the ovary, but is sometimes one-celled 

 by abortion, and in Dobinea is always one-celled. When
