sionally vary by layers; and some kinds arc so little certain in 

 character that they are called by floricultiirists "catch-flowers."^^ 

 Mr. Dickson has ably discussed the " running " of ]iarticoloured or 

 striped carnations, and says it cannot be accounted for by the 

 compost in wliich they are grown: "layers from the same clean 

 "flower would come part of them clean and part foul, even when 

 "subjected to precisely the same treatment; and frequently one 

 "flower alone appears influenced by the taint, the remainder coming 

 "perfectly clean." ^* This running of the jiarti-coloured flowers 

 fH^parently is a case of reversion by buds to the original imiform 

 tilt of the species. 



I will briefly mention some other cases of bud-variation to sho"w 

 h»w many plants belonging to many orders have varied in their 

 ficwers ; and many others might be added. I have seen on a snap- 

 dugon (Antirrhi)ium majus) white, pink, and striped flowers on 

 till same ])lant, and branches witli striped flowers on a red-coloured 

 va-iety. On a double stock (MathioJa incana) I have seen a branch 

 be.riug single flowers ; and on a dingy-purple double variety of 

 th( wall-flower (Clitiranthus chtiri), a branch which had reverted to 

 thi ordinary copper colour. On other branches of the same plant, 

 soue flowers were exactly divided across the middle, one lialf lieirjg 

 pu'ple and the other coppery; but some of the smaller petals 

 tovards the centre of these same flowers were pur])le longitudinally 

 striaked with coppery colour, or coppery streaked with ]n;rple. 

 A Jyclamen '"'-' has been observed to bear white and pink flowers of 

 tw) forms, the one resembling the Persicum strain, and the other 

 the Coum strain. Oenothera biennis has been seen^*^ bearing flowers 

 of three dift'erent colours. The hybrid GladioluacoloiUi occasionally 

 bears uniformly coloun.d flowers, and one case is recorded" of all 

 the flowers on a plant thus changing colour. A Fuchsia has been 

 seen"** bearing two lands of flowers. MirahiJis Jalapa is eminently 

 sportive, sometimes bearing on the same root ]iure red, yellow, and 

 wliite flowers, and others striped with various combinations ot 

 these three colours.*^ The plants of the Mirabilis, which bear 

 5uch extraordinarily variable flowers in most, probably in all, eases, 

 :)we their origin, as shown by Prof. Lecoq, to crosses between 

 liffereutly coloured varieties. 



Leaves and Shoots. — Changes, through bud-variation, in fruits and 

 lowers have hitherto been treated of; incidentally some remarkable 

 nodificatious in the leaves and shoots of the rose and Paritium, and
