 much larger, with erect purplish calyces and erect dull purplish- 

 orange-coloured petals, broadly obcordate, clawed. Stipules small, 

 ovate and toothed. There is a not uncommon plant, the G. inter- 

 medium Ehrh., which some call a species, but is now proved to be a 

 hybrid between these two^ : in it the flowers are sometimes erect, some- 

 times drooping, petals roundish and clawed, calyx and corolla inter- 

 mediate as to position and colour, heads of fruit usually sessile, with the 

 upper joint of the awn hairy but shorter than the lower one, and the 

 stipides round and toothed; but it varies in these respects, sometimes 

 resembling the one parent more than the other.

 these hybrids are stated to be fertile, forcing uron us the conclusion that the two 

 parents are themselves mere forms of the same species: or that, which is less 

 probable, true hybrids are fertile in the vegetable kingdom.
