rature, will intermix more readily than those of colder regions. 

 Strawberries, especially Hautbois, in their natural state, are 

 often sterile. 



Many plants, which Botanists have considered distinct, 

 are certainly not so ; as, for instance, Ixia (or Tritonia) cro- 

 cata, of which seminal varieties have been erroneously named 

 I. squalida, I. miniata, I. fenestrata, and 1. deusta ; Ixia 

 flexuosa and I. polystachya, are the same ; Babiana 

 stricta, B. villosa, B. sulphurea, and rubro-cyanea, are 

 not distinct ; I have had a natural seedling from Babiana 

 sulphurea with a pale eye like that of B. rubro-cyanea. 1 

 raised from the natural seed of one umbel of an highly ma- 

 nured Red Cowslip, a Primrose, a Cowslip, and Oxlips of 

 the usual and other colours, a Black Polyanthus, a Hose- 

 in-Hose Cowslip, and a natural Primrose bearing its flower 

 on a Polyanthus stalk. From the seed of that very Hose-in- 

 Hose Cowslip, I have since raised a Hose-in-Hose Primrose. 

 I therefore consider all these to be only local varieties, de- 

 pending upon soil and situation. I have raised a pow- 

 dered Auricula and a Primula Helvetica from the seed of P. 

 nivalis ; and I have raised a Primula Helvetica also from 

 P. Viscosa. 1 therefore esteem these Swiss Primulas to be 

 local varieties of one species. The Violas are proved by 

 cultivation to have been too much divided. The great 

 Hearts-ease, which adorns Covent Garden market, under 

 the name of Viola grandiflora, is found all yellow in Craven 

 in Yorkshire, under the name of Viola lutea ; with large 

 dark purple flowers, without any yellow, in the neighbour- 

 hood of Moor-rig, above the falls of the Tees, in the county 

 of Durham ; and with mixed purple and yellow flowers,
