Ovary 3- (rarely 2–4-) celled, with a single ovule in each cell; styles as many, from once to thrice 2-cleft.
The plants of this order are, with few exceptions, formed of celled surfaces and show the earliest type of an expanded leaf.
Ovary 2- (or in n. 5 falsely 3–4-) celled, with 1–several ovules in each cell.
The ovary is sessile, that is, it directly rests upon the main stem, and is usually three to five celled.
The berry (c) is four345 -celled, each cell containing a one-seeded nut.
And as he strove to lift it he felt in that unmistakable omnipotency of weight that it was seamed and celled with gold.
