be a slight reduction in these features traceable to the other parent. 
The pods were nearly as wide as those of Telephone, but were shaped 
like those of No. 1 (dominance of the blunt apex). The size of the 
seeds was intermediate ; the shape (apart from the question of 
smoothness or wrinkling) much nearer to that of Telephone. 
2. Telephone x Native pea No. 1.—Eighteen pollinations were 
attempted, 12 successfully, with 27 seeds as the result. With the 
exception of 2 seeds contained in a single pod, all these seeds were 
fully yellow as regards cotyledon colour. All the seeds were nearly 
smooth in surface ; some of them showed a very slight dimpling ; 
but all were smoother than any which I could find among the same 
generation of pure bred Telephone seed. In general form and size, 
on the other hand, they closely resembled the smoothest seeds of 
Telephone, which are also closely similar to those of Telegraph, 
differing entirely in these respects from No. 1. 
One cross out of the 12 gave rise to 2 fully green seeds, resembling 
in shape the other examples of the same cross. Occurring as they 
did on a green seeded plant the suspicion arises that these seeds may 
have been the result of accidental self fertilization. But I do not 
believe that this can have been the case ; firstly because the seeds 
were smooth, and secondly because their offspring behaved, so far 
as the evidence went, like those of a cross between smooth and 
wrinkled. The individual plant from which the pollen was taken 
was not specially examined, but all the seeds were gathered from the 
whole row of plants used for this purpose, and none of the cotyledons 
showed any trace of greenness. 
Of the above-mentioned crosses, 6 which were made in November, 
1902, resulted in 10 seeds, from only 4 of which fertile offspring were 
obtained. In both cases the seeds were sown shortly after they 
were gathered, and the plants closely resembled those from the 
reciprocal cross. 
C.— The Offspring of Cross-bred Plant —F 2 . 
1. Native pea No. 1 x Telephone. —The seeds produced by the 
cross-bred plants exhibited four distinct combinations of cotyledon 
characters, being in almost all cases readily distinguishable as
