The correctness of this statement is confirmed by the history of development. As far as I am aware, no one has profited by these inquiries of Brown, in order to solve similar anomalies which obscure the clear perception of affinity; for which ob- ject the Ranunculaceai present an excellent opportunity. The one-seeded plants of this family have been divided according to the difference of pendent and erect ovules (?) into Ranun- culacece and Anemoneae; and botanists have remained content with believing in such an important distinction even between plants so nearly allied to each other. But the ovule in these two divisions is at a not very early state exactly similarly con- structed, and is ovutum adscendens anatropum, figs. 1—2 ; at a subsequent period the ovarium either grows alone upwards, when we have an ovutum erectum anatropum, fig. 3, or the ova- rium is compelled to employ for its development the space. below the ovulum, which then curves from the placenta down- wards and becomes spurie pendulum, anatropum raphe aversa, fig. 4. In several species no difference is perceptible at the time of flowering (for instance between Ranunculus and Myo- surus); and in all the others intermediate forms run so gra-.
