FLOWERS. 39 



Hence, Flowers produced in dark or shady 

 confined situations are either imperfect, or des- 

 titute of their habitual size and beauty. 



Double Flowers are those in which the sta- 

 mens are transformed into petals ; or in which 

 the latter, or the sepals, are multiplied. They 

 should not be confounded with Proliferous and 

 Discoid Compound Floicers. This difference 

 will be explained immediately. 



Although no certain rules for the production 

 of double flowers can be laid down, yet it is 

 probable that those flowers have the greatest 

 tendency to become double, in which the parts 

 are habitually multiplied. 



Plants whose flowers have naturally nume- 

 rous stamens and pistils, are those which 

 usually become double, these being the parts 

 generally transformed into petals. 



Double Flowers are therefore least to be ex- 

 pected in plants with fewest stamens. 



Whenever the parts of a Flower adhere by 

 their edges, forming what are called one sepal- 

 led {gamosepaloiis) calyxes or one petaled 

 (gamopetalous) corollas, or where the stamens 

 are combined either into one or few parcels, the 

 tendency to multiplication seems checked, but 

 this is by no means general, as we have double
