Variant Hybrid Tigridias
It will be seen that the different tigridias hold rather closely to the same characteristic type of flower. There is, nevertheless, a good range of variation as to size, precise contour of petals, and color. Of course the hybrids show combinations of characters that are not united in any single one of their parents. There is the usual tendency to the segregation of these characters into many new groups in the second generation.
