mvobiGve{CyatMum). Each, stamen constitutes a male monandrous 

 flower, -whose lower portion at the articulation of the filament would 

 represent a receptacle. The alternate scales with the staminal 

 bundles would form the calyces or epicalyces of the male flowers. 

 The gynseceum, constituting a central female flower, the disk, 

 which is sometimes observed below the ovary, would be a oalycule or 

 female calyx. This interpretation, which we consider inadmissible 

 and useless, is the fashion at present, and most authors ^ follow it, 

 and will follow it doubtless for some time in their works. 



II. EICINUS SERIES. 



In Ricinus^ (fig. 153-162), the flowers are regular and monce- 

 , cious. On the convex receptacle of the male flower is inserted a 

 calyx, formed of flve sepals (or more rarely of a smaller number), 

 definitely disposed, in valvate prsefloration. Within are very 

 numerous stamens, whose ramifled filaments in polyadelphous bundles 

 are terminated by fine divisions, supporting at the apex a small 

 bilocular extrorse anther, with short almost globular cells, dehiscing 

 lengthwise.^ In the female fiowers there is only a calyx and a gynse- 

 ceum. The former is similar to that of the male flower. The free, 

 globular ovary has three cells, two of which are anterior. It is sur- 

 mounted by a cylindrical style, soon divided into three elongated 

 branches, flattened bi-partite, all bearing on their internal face and 

 reflexed edges large stigmatic papillse coloured red. In the inner 

 angle of each cell is a descendent ovule, directed like that of 

 Euphorbia, and capped by an analogous obturator. The fruit is 

 three-shelled,* smooth, or generally covered with prickles, which
