PLATE 57 



Somatic chromosomes of different derivatives produced by a triploid C. 

 capillar is plant compared with a normal diploid chromosome complex (the capital 

 letters representing the three chromosome types: A, the largest chromosome, C, 

 the smallest chromosome, and D, the satellited chromosome). X 3650. 



g, Triplo-A (simple trisomic). 



h, Triplo-D (simple trisomic). 



i, Triplo-AC (double trisomic). 



j, Triplo-AD (double trisomic). 



fc, Triplo-CD (double trisomic). 



I, Chromosomes of a triploid plant possessing an additional proximal fragment 

 of the satellited chromosome. 



m, Chromosome complex of a normal diploid plant.
