genera in India, which do not however include many 

 species of niiu.li economic importance. The variety, chiefly 

 in the arrar^gement and number of the carpels, and their 

 position relative to the tube of the calyx, may be reduced 

 to three Su!) types, each represented in India either by 

 native or cultivated species. 



Bramble {Rnbus) may serve as type of the Sub-order 

 Rosea?, n^.avked by numerous free carpels.

Cherry, or any species of Pruniis or Fygemn, of the Sub- 

 order Drupace?e, marked by a single free carpel, drupaceous 

 in fruit. And the 



Loquat [Eriobotrya), Phot'uiia, or Apple {Fyrus), of the 

 Sub-order Pomacece, marked by one or more carpels ad- 

 herent to the calyx-tube, so that the ovary is inferior. 



IMost ot the species of this large Family agree in their 

 perigynous stamens, which are usually indefinite ; poly- 

 petalous corolla, prone to become " double " at the expense 

 of the stamens, as in Rose and Kerria; and the essentially 

 apocarpous pistil. 



In Pomacece, if the fruit be cut across, it will be seen 

 that tlie carpels do not cohere inter se^ though pressed
