Effects of Multifold Crossing. 



Mr. Veitch has raised several crosses of the fourth generation, 

 combining four or five species in the results. The following are 

 a selection to illustrate the fact that the species first used 

 frequently retain no visible trace of their existence in the latest 

 offspring, which is much more conformable to the form and 

 colour of the species last introduced into the cross. 



Hippolyta (fig. 44, k) = Queen of the Yellows x B. multicolor, 

 var. Curtisii. This contains jas., 2 jav., Brook., and mult., var. 

 Curtisii. The form is nearly identical with that of B. mult. 

 (fig. 43, d), but larger ; the increased size being probably due to 

 the effect of B. javanicum. The leaf is an enlarged form of that of 

 B. multicolor. This cross also illustrates the strong propotency 

 of this species, for there is no appreciable difference of any 

 importance in form or colour between Hippolyta and the second 

 generations, Nos. 32 and 301 =Pr. Eoyal x B. mult. var. Curt., 

 which contains jas., jav., and mult. only. 



Yellow Perfection=~Loic& Wolseley (fig. 44, m) x B. Teys- 

 mannii (fig 43,/). This contains jas., 2 jav., Brook., and Teys. 

 It is intermediate between B. Brookeanum and B. Teysmannii, 

 with the leaf more nearly that of the latter species. 



Primrose and No. 456 = Maiden's Blush x B. Teysmannii. 

 This contains jas., 2 jav., Brook., and Teys. In Primrose, 

 B. Teysmannii overpowers everything ; but in No. 456 B. 

 Brookeanum is more apparent in colour and form. 



Little Beauty and No. 318 (fig. 44, n) =Monarch x B. malay- 

 anum (fig. 43, ^7). This contains five species, and one of them 

 twice — viz., jas., 2jav.,Lobb., Brook., malay.; yet the result 

 is almost purely B. malayanum, the leaf only being larger, yet 

 even that has the russet scales of this species. 



Artemis= Ophelia x B. Teysmannii. This contains jas., 

 3 jav., and Teys. The large lobes may be attributed to B. 

 javanicum', but the size and colour are nearer to B. Teys- 

 mannii. 



Astasia — B. Teysmannii x Maiden's Blush. This contains 

 2 jas., jav., Brook., and Teys. B. Brookeanum is seen in the 

 slender tube, B. Teysmannii in the general form and colour, as 

 well as in the leaf. 



Juliet, Portia, Imogene, and Purity = B. Teijsmannii x
