XLII. Account of a newly produced Hybrid Passiflora. By 

 Joseph Sabine, Esq. JP. R. S. $c. Secretary. 



Read, November 7, 1820. 



In the Paper on the production of Hybrid Vegetables, 

 which was read before the Society in December last, Mr. 

 Herbert has stated his belief that an intermixture might 

 be obtained between " the Scarlet Passiflora Princeps,* 

 and the hardy Passiflora cserulea." The experiment, which 

 had then been begun, has since been successfully completed 

 at Fulham, in the nursery of Messrs. Whitley, Brames, 

 and Milne, by Mr. Thomas Milne, a Fellow of this So- 

 ciety, and one of the partners in that firm. The flower which 

 was exhibited at the Meeting, on the fifth of September last, 

 was produced by a plant raised from the seed of P. race- 

 mosa impregnated by P. ca;rulea. 



The Passiflora racemosa, since its introduction into this 

 country, has not produced fruit spontaneously, the cause 

 of which may be attributed to some imperfection in the 

 state of its farina, occasioned probably by want of a proper 

 temperature. In the experiment I am now about to record, 

 this defect was supplied from the more perfect stamina of 

 the P. caerulea. During the months of May, June, and July, 

 1819, about thirty flowers of a plant of the first named 

 species were impregnated artificially by Mr. Milne, with 



* Now usually called Passiflora racemosa.
