Families 1, 4, 5, and 6 were derived from plants of the 
lieptandra form proper, the total offspring of 159 included :— 
8 extreme heptandrci form ( i.e., with all, or nearly all, the 
flowers non-petaloid). 
143 lieptandra form proper (i.e., with a large number of flowers 
having a petaloid upper lip). 
1 intermediate lieptandra form (i.e., with some flowers having 
both the upper and the under lip petaloid). 
7 particular form not recorded. 
159 
In the one intermediate lieptandra plant recorded in this group 
of families normal flowers were not produced. The furthest point 
reached in the reversionary series was that in which the lower lip 
was deeply lobed, and only united for a short distance with the 
upper lip to form a tube. 
Families 2 and 3 were derived from plants of the intermediate 
lieptandra form ; the total offspring of 97 included : — 
7 extreme lieptandra form, 
36 lieptandra form proper, 
49 intermediate lieptandra, 
5 particular form not recorded, 
97 
About two-thirds of the intermediate lieptandra plants eventually 
produced some normal flowers. 
From the facts given above it is evident that the lieptandra 
character is inherited, and that from lieptandra parents only lieptandra
