with the segments of the calyx reflexed ; the 

 anthers (b) are more firmly attached to the 

 filament; the style (c) is not cleft, and the 

 stigma is two-lobed and capitate. The fruit (d) 

 has a thick opaque skin, and the eye of the 

 calyx is larger ; the leaves are also covered on 

 the under surface with glands or cells, filled with 

 a fragrant oil formed by the limb, as show^n at 

 (e), which represents the appearance of the leaf 

 when held up to the hght. There is often a soli- 

 tary flower on a separate pedicel, at the foot of 

 the raceme ; and there are frequently ten sta- 

 mens instead of five, and no petals, the petals hav- 

 ing been changed into stamens — a metamorphose 

 the reverse of that which generally takes place. 

 The most ornamental kinds of Currant are 

 R. multiflorum, with very long drooping racemes
