242 NATURAL mSTOBY OF PLANTS. 



size and form between the inner and outer petals begin to ^ow less 

 in Jll. brcvipes.^ Here the inner petals are not so narrow as the outer 

 ones, but attain to about two-thirds of their length. In these two 

 latter species also, the branch accompanying the Hower is much less 

 developed at the season of its expansion. 



Thus we gradually arrive at a stage which puts it out of our power 

 to make another genus for the curious species that we have named 

 M. madafjnHcnrienxix; whose small Howers have a campanulate corolla, 

 with six nearly equal lobes, which even appear arranged in a single 

 whorl when adult. The calyx is here short and gamosepalous, and 

 the corolla, instead of being reflexed from its base, is erect like a bell, 

 with thick walls, and ends in six acute vertical teeth. Its valvate 

 prailioration is very well marked. As to the androceum and ovary, 

 they are exactly those of the other species of this genus. The style 

 is much broader than the ovary itself, forming a large, fleshy, 

 papillose, depressed head, surrounded at tlie base by a sort of annular 

 cup. This species is frutescent and climbing. The leaves are alter- 

 nate and simple. The flower is borne on an erect slender peduncle, 

 accompanied by a young branch or leaf-bud, and is axillary to the 

 leaf. 



Only six species of Monodora are known, of which one-half belong 

 to the west of tropical Africa.^ The others grow on the east coast, or 

 in ^ladagascar.* We may define these plants as Aiionncccp, ^vith the 

 gyna^ceum of a Poppy — i. e., with the ovary and fruit unilocular and 

 of parietal placentation.
