It is worth noting that some dark pink doubles were very beautiful 

 flowers : my experiment was not on a large enough scale to make certain 

 of my figures but they pointed to a 1 to 1-5 ratio, the wdiite double being 

 the 1. 



Hainj leaf steinn and front of leaf . In reality all stems are to some 

 extent hairy, but some appear to be " hairy " because the hairs stand 

 out from the stems and are more numerous. On the other hand, the 

 front of the leaf may be quite glabnjus. 



In a cross Virginiana x Cliiloensis the i^,'s had " hairy " stems and 

 the front of the leaves was hairy. The jP/s selfed produced 



32 " Hairy " stems 10 n(.)t " hairy " 



29-1-3 (marked '. " consider hairy ") Hairy front of leaf 10 Olabrous. 



Clearly a 3 to 1 in each case. 



An F., generation, from a selfed F^ of a cross CIdloensis x Virginiana, 

 have yielded plants showing marked segregation of numerous characters 

 — too numerous for me to go into carefully in the short time at my 

 disposal.
