" separate with tolerable certainty by grafting from the branches 

 " that bear them." A branch, also, on an old tree of the rose-coloured 

 variety has been seen to " revert to the pure white colour, an 

 " occurrence less common than the departure from it." ^^ 



Crato'gus oxyacaniha. — A dark pink hawthorn has been known to 

 throw out a single tuft of pure white blossoms;'^ and Mr. A. 

 Clapham, nurseryman, of Bedford, informs me that his father had a 

 deep crimson thorn grafted on a white tliorn, wliich durmg several 

 years, always bore, high above the graft, bunches of white, pink and 

 deep crimson flowers. 



Azalea indica is well known often to jd reduce new varieties by 

 buds. I have myself seen several cases. A plant of Azalea indica 

 variegaia has been exhibited bearing a truss of flowers of A. ind. 

 ghdsfatiesii " as true as could possibly be prodttced, thus evidencing 

 the origin of that fine vai'iety." On another plant of A. ind. varie- 

 fjata a perfect flower of A. ind. lateritia was produced ; so that both 

 (jledstanesii find lateritia no doubt originally appeared as sporting 

 branches of A. ind. varieyata!^ 



Hibiscus (Faritium trictispis). — A seedling of this plant, when some 

 years old, produced, at Saharunpore,^^ some branches " which bore 

 leaves and flowers widely dilierfnt from tlie normal form." " Tbe 

 abnormal leaf is much less divided, and not acuminated. The 

 petals are considerably larger, and quite entire. There is also in 

 the fresh state a oonspicvtons, large, oblong gland, full of a viscid 

 secretion, on the back of each of the calycine segments." Dr. King, 

 wlio subsequently had charge of these Gardens, informs me that a 

 tree of Paritlum tricuspis (prob^ibly the very same plant) growing 

 there, had a branch buried in the ground, apparently by accident ; 

 and this branch changed its character >^-ouderfully, growing like a 

 bitsh, and producing flowers and leaves, resembhng in shape those 

 of another species, viz., F. tiliaceum. A small branch sjjringlng 

 from this bush near the ground, reverted to the parent-form 

 Both forms were extensively propagated during several years by 

 cuttings and kept perfectly true. 



Althcea rosea. — A double yellow Hollyhock suddenly turned one 

 year into a pure white single kmd; subsequently a branch bearing 

 the original double yellow flowers reappeared in the midst of tlie 

 branches of the single white kiud.'^^ 



Felargonium. — These highly cultivated plants seem eminently 

 liable to bud-variation. I will give only a few well-marked cases. 

 Gartner has seen^^ a plant of F. zonule with a branch having white
