B. Isocarpce. Carpels equal in number to the sepals and petals, usually five, 
rarely four, and coherent into a generally superior ovary (except Order i, Family i, 
where there are only two median carpels) ; diminution of the number of stamens 
does not occur (except in Order i, Family i); in Orders 2 and 3, on the other 
hand, a perfect staminal whorl is usually interposed ; in Order i the stamens are 
superposed on the petals, and a number of seeds spring from an elevated axial 
placenta in the unilocular ovary; in Orders 2 and 3 the ovary is multilocular and 
many-seeded.

II. Eleutheropetalse or Dialypetalae. 
Petals free, sometimes wanting. 
C. EucyclcB, Corolla very rarely wanting ; stamens very commonly twice or 
three times as many as petals by the interposition of a perfect or even double 
(Orders 6, 7) whorl, or by the interposition of an imperfect whorl differing in number 
from the corolla (Order 5) ; in the isostemonous flowers the stamens are sometimes 
superposed on the petals (Order 4), or the original stamens branch (especially in 
Orders 2, 3, and 8); the number of carpels often the same as that of the sepals 
and petals (Orders 7, 8), but commonly less — two, three, or four ; ovary unilocular 
with parietal placentae in Order i, in the others multilocular; seed generally without 
endosperm.
