MIMULUS LUTEUS. 



CHAP. III. 



Several flowers on this plant were crossed with pollen from other 

 flowers on the same plant, and several other flowers were 

 fertilised with their own pollen. The seed thus produced was 

 allowed to germinate on bare sand; and the seedlings were 

 planted in the usual manner on the opposite sides of six 

 pots. All the remaining seeds, whether or not in a state of 

 germination, were sown thickly in Pot VII. ; the three tallest 

 plants on each side of this latter pot being alone measured. As I 

 was in a hurry to learn the result, some of these seeds were sown 

 late in the autumn, but the plants grew so irregularly during 

 the winter, that one crossed plant was 28J inches, and two 

 others only 4, or less than 4 inches in height, as may be seen 

 in Table XXI. Under such circumstances, as I have observed 

 in many other cases, the result is not in the least trust- 

 worthy ; nevertheless I feel bound to give the measurements.
