48 General Notices. 



in cultivation. I have now (June, 1831) flowering in the Edinburgh Botanic 

 Garden many seedling [)lant.s from S. atropurpurca, which are precisely 

 S. straminea, though the size of the flower varies in the different specimens. 

 I have also seedling plants of S. picta, in some of which the corolla, though 

 perfect, is not above a (piarter of an inch long, and pure white; in otliers, 

 the corolla never appears at all j yet, both last year and this, specimens of 

 this description have produced abundance of seeds. I hope these blunders 

 are excusable on the first introduction of a little-known genus into cul- 

 tivation, as 1 myself contributed to the confusion ; but the persevering in 

 them would be without apolog}. I learn from my accurate friend Mr. 

 Cruikshanks that the forms in Salpiglossis vary greatly in their w ild state." 



The case of seeds being duly produced from blossoms which have been 

 abortive in corollas, has been long exemi)lified in /'iola odorata, and V. 

 hirta ; although in these it usually occurs during the summer, and perhaps 

 autumn, after their proper season of blooming, namely, the spring. Da- 

 tura Tdtiila has also been witnessed by the Rev. Mi. Creed, a gentleman in 

 Norfolk or Sufl^olk, to bear apetalous blossoms, which were, nevertheless, 

 duly productive of seeds. 



Although the sportiveness of the salpiglossises above named is considered 

 not to have arisen from one kind having impregnated another, that new 

 kinds may be generated by cross-impregnation is proved by the existence 

 of the Salpiglossis Barclay oV/a, mentioned Vol. VII. p. 597. as a hybrid 

 from seeds of S. picta which had been impregnated with the pollen of 

 S. atropurpurea. — J. D. 



Additional Hybrid Calceolarias. — Professor Graham, in his description 

 of the new Calceolaria angustiflora (not angustifolia), published t. 3094^. in 

 the August number of Curtis's Botanical Magazine, exiiibits his reasons 

 for considering C. angustiflora a species ; and that it is not a British hybrid 

 he proves circumstantially. To these reasons and remarks he adds : — 

 " Still a contmued experience of the tendency to produce hybrids which 

 this genus possesses, renders me more and more sceptical about the title 

 which very appreciable varieties of form have to be considered specifically 

 distinct. In a former number of the Edinburgh I'liilosopliical Journal, I 

 noticed some nmle plants which had been raised by Mr. Gardner, at Gran- 

 ton, near Edinburgh, by artificially impregnating some of the most distin- 

 guishable kinds of Calceolaria. Since tiiat time, the same cultivator has 

 obtained all sorts of mixtures, and blended different species into one 

 another, through an infinity of gradations." 



In our Vol. VI. p. 493, 49 k, an extract from Professor Graham's com- 

 munication to the Edinbtirgli I'hiluxophical Journal is given ; in w hich the 

 hybrid calceolarias there noticed are said to have been raisetl by " Mr. Mor- 

 rison, gardener to Lord President Hope, at (iranton." ^^'hether the hy- 

 brids above alluded to, through some mistake in the names of the parties, 

 be the same witii those mentioned in Vol. VI. p. 493. or not, we cannot 

 tell, nor does it much matter. If they be identical, one interesting fact 

 remains, namely, that, subsetjuently to the notice referred to, additional 

 hybrids have been originated ni the vicinity of Edinburgh. To these, for 

 tne sake of consj)ectiveness, may be added the hybrid mentioned in p. 310. 

 of Volume VII. At the show, July .5., of the London Horticultural 

 Society, Miss Martineau exhibited " a (Calceolaria raised from seeil of C. 

 Fothergllh, fertilised by C. corymbosa." At the exhibition on June 21., 

 Mr. James Young produced " some fine specimens of hybrid calceolaj'ias." 

 Of these report has more than once reached us, and attested tiiem most 

 beautiful; but an advertisement in our August Number informs us that the 

 majority of these are identical with those above nameil, Messrs. Young 

 having " become the exclusive proprietors of the fine hybrid calceolarias 

 raised in Scotland, and partly described in the Gardener's Magazine, 

 Vol. VI. p. 494." Of tliese Messrs. Young offer five distinct varieties, a
