furnished additional data on the inheritance of certain types of 
albinism, and as a result of a cytological investigation of the albino 
seedlings concluded that plastids are entirely absent in plants of 
that type. Linpstrom (43), in a comprehensive study of chloro- 
phyll inheritance in maize, described the behavior of eight distinct 
types, including those already reported on. In every case the 
inheritance was shown to be Mendelian. Two of these types, 
albino and yellow, are seedling characters, the plants failing to 
mature because of the absence of a sufficient amount of chlorophyll. 
In a third type, known as “‘virescent,”’ the seedlings at first are 
yellowish white, but later become green, and in the mature condi- 
tion cannot be distinguished from normal green plants. The five 
other characters described by Linpstrom as “‘golden,’’ “ greenish- 
striped,’ ‘‘japonica white striped,” ‘japonica yellow striped,” 
and “fine striped,” are manifested only in the mature plants; 
the young seedlings have a wholly normal appearance. From these 
studies Linpstrom concluded that plastid inheritance in maize 
is typically Mendelian. 
At the present time, however, cases are known in which the 
inheritance of certain aberrant chlorophyll types is not Mendelian. 
ANDERSON, in genetic studies as yet unpublished, has found that 
in a certain strain of maize there are produced some plants which 
are uniformly green, others uniformly yellowish green without suffi- 
cient chlorophyll to reach maturity, and still others with distinct 
yellowish green and green stripes.t Breeding experiments so far 
carried out have failed to show any inheritance of the unusual 
character through the male parent. The plants which are yellowish 
green lack a sufficient amount of chlorophyll to reach maturity, 
and no offspring have been obtained from them. The striped 
plants, either when self-fertilized or when pollen is used from a 
green plant of an unaffected strain, produce some green plants, 
some yellowish green plants, and some striped plants in varying 
proportions, which seemingly depend upon the amount of yellowish 
green tissue in the region of the plant producing the ear. Ears 
have been obtained which have produced only yellowish green
