218 LOCK : 



Thirty-six plants were obtained from the cross between 

 No. 76/07 and a typical N. langsdorfii (A). These plants were 

 all closely similar in habit and the shape of the flowers. In 

 these respects typical N. langsdorfii would appear to be almost 

 completely dominant over the hybrid type. From Table VI. 

 it may be seen that the size of the flowers is again intermediate. 



(2) N. langsdorfii typical (A) x N. alata (of hybrid 

 origin — with mauve flowers). (No. 75/07.) 



Of 11 plants, 6 had eorallas of a yellowish colour tinged with 

 purple, whilst in 5 the eorallas were pale-yellow without any 

 trace of a purple tmge. The hybrid origin of the alata parent 

 is thus clearly indicated. In other respects the 9 plants 

 grown in the open were all closely alike. The shape of the 

 flowers was somewhat nearer that of N. alata than that of the 

 other parent. Plate IX. shows one of two very stunted plants 

 grown under glass. 



The following plants were raised in F 2 : — 



No. 75/07 self-fertilized = (No. 73/08), 12 plants. 

 No. 75/07 X N. langsdorfii (A) = (No. 99/08), 4 plants. 

 N. langsd. A X No. 75/07 = (No. 100/08), 29 plants. 

 N. alata (of hybrid origin, but with white flowers) X 

 No. 75/07 = (No. 103/08), 16 plants. 



The tube lengths of one flower from each of these plants 

 are recorded in Table VII. The same remarks apply as in 

 the preceding case.
