AMARYLLIS PARKERI. 



[A. Belladonna var. bland a x Brunsvigia Josephinae] 

 By A. Worsley, F.R.H.S. 



This bi-generic hybrid should be of great interest to those who study 

 genetics, because the parents are so very dissimilar that we are presented 

 with no less than 17 divergent characters to work on, and the fact that 

 the hybrid is self-fertile will enable the subsquent generations to be 

 analysed. Moreover the history of the hybrid is fully ascertained, and 

 the reverse cross has been raised and flowered. 



In reference to the interesting notes published in the " Gardeners' 

 Chronicle," vol. xlv. (1909) pp. 37, 92, by Messrs. C. G. Van Tubergem 

 junior, Mr. W. Watson, and Mr. H. J. Elwes, I would note that it cannot 

 be said in the same breath both that the Kew form of A. Parkeri may 

 possibly be the progeny of the original cross made by Herbert, and also 

 that Messrs. Van Tubergen's cross may differ therefrom because it is the 

 reverse cross to that made by Herbert. This may be true of the A. Parkeri 

 raised by Mr. Parker, for this was raised on A. Belladonna, but Herbert's 

 hybrid was raised * the same way as Messrs. Van Tubergen's — that is, on 

 Brunsvigia — the only difference being that Herbert's male parent was the 

 var. A. blanda (now lost).
