Re[2]: natural variegation - terms


     Thanks for this and the reference. The adaptive significance is what I 
     am after some ideas on. Schismatoglottis is interesting since 
     populations (within a species) occur in the wild in which there are 
     individuals with markedly different clonally stable variegation 
     patterns and individuals with no variegation at all.

Dear Alistair and Dewey;
        In the recent book "Variegated plants in Color" by Hirose and
Yokoi, Mr. Hirose refers to natural patterns you mention as 'Pattern 
Variegation'. They occur in a wide range of plants from Begonias to Aroids, 
Caltheas, Coleus and more.
        This is opposed to 'True Variegation' the result of one or more
mutations and very rarely viruses. True variegation can also be found in 
some plants with pattern variegation and in some cases it is difficult to 
tell which came first as some plants showing variegation have been in 
cultivation for so long that the natural (original) patterns are little 
known.
        I don't think there is any relationship between pattern variegation
and true variegation. That is, pattern variegation plants are not more 
likely to produce true variegation than plants which normally show no 
variegation. There are also abundant examples of true variegation plants 
with no pattern variegation species in the same genus and vice versa.
     
        Once can only assume that pattern variegation exists because of its
adaptive value.
