OF THE OVULES.

In a species of Triumfetta (see p. 260), of which I 

 examined dried specimens, the 

 ovary was open and partly folia- 

 ceous ; it bore on its infolded 

 margins ten erect leaflets, repre- 

 senting so many o\niles ; each 

 leaflet was conduplicate, the back 

 being turned towards the pla- 

 centa. 



On the other hand, there are 

 cases in which the leafy coat of 

 the ovule, in place of being a 

 distinct organ, seems to originate 

 from the margin of the carpel- 

 lary leaf itself to be, as it were, 

 a lobule or small process of the 

 carpel, and not an absolutely 

 new growth. Thus, Planchon,^ 

 from an examination of some 

 monstrous flowers of Drosera in- 

 termedia ^ was led to the inference 



that the oviQes are analogous to &c., TrifoUum repem.

 leaves. This acute botanist was
