NOTES ON SOME HYBRID TUBEROUS SOLANUMS. 



129 



The description of the hybrids, which is given in the R.H.S, 

 jouENAL, vol. XXXV. p. cGxxvii., is taken from an average plant [No. 2] , 

 but the calyx of the hybrids varies somewhat ; in the case of one plant 

 the tip is awl-shaped like that of ^S*. tuberosum. A remarkable fact 

 in regard to one of the plants [No. 3] is that its last blooms were 

 siar-sliaped, like those of S. Commersonii (cf. fig. 58 with fig. 59, b),

although all the earlier ones were pentagonal like those of iS'. tuhe- 

 rosum. Before the last blooms were formed the plant had been sent 

 long distances by rail, with insufficient protection, and exposed to frost 

 for a time, so that the fiower-buds were probably injured, and this may 

 have caused the loss of the dominant factor for form. The colour re- 

 mained lilac unchanged.* Photographs of these are shown at fig. 58. 

 Fig. 60 shows the berries of both parents and the hybrid. 



* It may be worth recording that upon a plant of S. tuberosum , which had 

 a similar transit by rail, the berries on one branch were round, with spots very
