of a greenish-grey colour, more or less flecked with purple 
spots ; the grey colour showed, however, a tendency to become 
first orange and then brown on exposure. The seeds were 
strongly dimpled (starch grains of the round type) ; they 
were large and of a characteristic somewhat flattened form. 
The pods were very wide, and were constricted between 
the seeds, the parchment layer being undeveloped. 
The “female” parent had smooth spherical seeds, with a 
nearly transparent testa. The flowers were white and the 
axils green ; the pods were inflated and small (narrow). 
The seeds immediately resulting from the cross were 
indistinguishable from the ordinary spherical seeds of the 
native pea. The cross-bred plants (F x ) had coloured flowers 
and axils, and the testas were coloured like those of the 
“male” parent. The seeds were intermediate in size and 
some were of a somewhat square shape, unlike that of either 
parent, whilst others showed a nearer approach to the flat¬ 
tened form of French sugar seeds. All were distinctly 
indented. The pods were inflated, but showed some signs of 
a reduced development of the parchment layer, especially 
towards the base (inflated pod almost completely dominant). 
The width of the pods was intermediate between those of the 
two parents. 
In (F 2 ) the following groups of plants were to be distin¬ 
guished :— 
(«) Pods inflated ; seeds indented ; testa grey, with 
purple spots ... ... ... 39 
(6) Pods inflated ; seeds indented ; testa grey, without 
purple spots ... ... ... 11 
(c) Pods inflated ; seeds smooth or nearly ; testa 
colourless ... ... ... 12 
( d ) Pods soft ; seeds indented ; testa grey, with purple 
spots ... ... ... 11 
(e) Pods soft ; seeds indented ; testa grey, without 
purple spots ... ... ... 5 
(/) Pods soft; seeds smooth or nearly; testa colourless 8 
The ratio between the number of plants with inflated pods 
and the number of plants with soft pods, was thus 62 : 24 or 
2*6 : 1 .
