144 ILLUSTRATIONS OF INDIAN BOTANY. 



Examples of some of these are given in the supplementary plate 147 h. Of the series, the 

 most difficult to understand is Mimusops. The flower of this genus is very complex. It consist? 

 of t^vo rows of sepals, of two series, or whorls, of lobes to the corolla. The outer series has 

 twice as many lobes as there are sepals, or lobes to the calyx (12 or 16), these are arranged in 

 pairs alternate with the midribs of the sepals ; within is a second series equaling the number of 

 sepals and opposite their midribs : opposite these stand the fertile stamens, and alternate with 

 them the sterile ones. The arrangement may be thus illustrated. Let S stand for sepal, C for 

 corolla, a for anther, or fertile stamen, and f for the petaloid sterile filament. Then let us 

 take an 8-partite species, say Mimusops Elengi, as being most common, for the example, 

 though that is not constantly 8 as I have repeatedly found decandrous flowers on the same 

 fpecimeu with octandrous ones.

This is a rude but sufficiently expressive diagram and one easily given and understood. It 

 would be still better shown by five concentric circles intersected by transverse lines. 



As stated above the number of parts of the flower of Mimusops is liable to vary. In 

 M. Elengi I have not seen fewer than 8 parts to the whorl, but often 10 and even 12. In 

 M. hexandra octandrous flowers are of frequent occurrence, but I have not yet seen more. 

 De Candolle's division into 8-androus and 6-androus species must, therefore, be received with 

 some degree of latitude. I had very nearly referred a specimen of the latter form, having 

 8-androus flowers mixed with hexandrous ones, as a new species to the octandrous section, and 

 probably would have done so, had I not given it to the draftsman to make a drawin(T, when he 

 lortunately stumbled on a hexandrons flower, which led to more minute examination and showed 

 that the two forms were mixed on the same branch, in the same way as I had already seen in
