80 ESTABLISHMENT OF VARIETIES IN COLEUS. 



PLATE 2 Continued. 



FIG. 15. A leaf with no yellow and with almost no red on the under surface. A type quite 

 like that described for the original Coleus blumei. This type appeared thus 

 far only as a fluctuating variation as a winter condition of a few plants of the 

 type of figure 10. At the time this was painted, January 24, 1914, the oldest 

 leaves of the plant were typical for type 10 and the younger leaves were uni- 

 form for the coloration here shown. The under surface of this leaf had only 

 a few red blotches similar to those of figure 10a. 



17. A leaf with irregular pattern, developed from type of figure 2. 



18. One of the leaves of the plant shown in figure 21, showing the absence of yellow in 



half of a leaf. 



19. Leaf painted on January 18, 1914, showing rather marked increase of yellow in the 



type of figure 2 during winter. Painting was made after the yellow areas had 

 begun to turn to white. 



20. Painted on July 5, 1913. Typical of the most extreme fluctuation of type figure 2 



in regard to increase of yellow. 



PLATE 3. 



FIG. 21. Young plant 12514, grown from a bud showing sectorial loss of yellow, by bud 

 variation in half of the bud. Photographed and painted on November 9, 1912. 



22. One of the leaves in a branch showing sectorial loss of green in the pattern of 



figure 6. In this leaf the loss appeared in one side of the leaf. Painted on 

 December 4, 1913. 



23. Leaf classed as green-yellow spotted-red blotched. The red epidermal blotches are 



large and much coalesced, which is a frequent variation from the condition of 

 figure 5. 



24 and 24a. Lower and upper surfaces of the same leaf from a young plant grown 

 from a bud variation which involved a sectorial loss of red, giving solid red 

 upper center from solid red on both surfaces. In this leaf these two types are 

 sharpty limited to one half of the leaf. The young plant exhibited loss of 

 yellow by fluctuating variation. The leaf painted was an upper leaf showing 

 no yellow, but at the same time the older basal leaves possessed much yellow, 

 as in type of figure 10. 



25. Leaf painted on March 25, 1913, showing sudden bud variation affecting only the 



half of a leaf. The plant possessed leaves of the type figure 2 shown in the 

 left side. A reversal of the relative position of the green and the yellow gave 

 the pattern of figure 6 in the right side of the leaf, as shown. 



26. Taken on March 28, 1913, showing the fluctuational decrease of yellow, giving a 



poorly defined yellow border. During the following summer the plant returned 

 to the typical form of type 2. This leaf is quite typical of the increase of green 

 during winter seen in numerous plants of type 2, as mentioned on page 22 of 

 the text.. 



27. Painted on July 27, 1913, showing an irregular pattern with yellow at the border 



about the apex of the leaf and illustrating a fluctuation produced from both 

 types 2 and 4. Leaf also shows irregular distribution of epidermal red. 



28. Leaf classed as green-red blotched, but with few large blotches somewhat run 



together. 



29. Leaf also classed as green-red blotched, but with fine blotches much coalesced. 



PLATE 4. 



Three plants photographed on January 16, 1914, all descended from branch 2 of plant 1. 

 Plant 125111 has leaves uniformly entire and of the pattern green-yellow-red blotched (fig. 2). 



Tips pinched off to prevent early flowering in greenhouse. 

 Plant 1251412 has leaves uniformly entire and of the pattern green-red blotched. 

 Plant 123153. Old leaves entire, youngest leaves deeply laciniate. Typical condition 

 during early winter for plants showing the fluctuation in leaf shape.
