which were thus legitimately fertilised; and they pro- 

 duced many dozen fruits, each containing two good 

 seeds. I fertilised in the same manner three heads 

 on the same long-styled plant with pollen from another 

 long-styled plant, so that these were fertilised illegiti- 

 mately, and they did not yield a single seed. Nor did 

 this plant, which was of course protected by a net, 

 bear spontaneously any seeds. Nevertheless another 

 long-styled plant, which was carefully protected, pro- 

 duced spontaneously a very few seeds ; so that the long- 

 styled form is not always quite sterile with its own 

 pollen. 



Faeamea [sp.?] (Eubiacb^). 



Fritz Miiller has fjiUy described the two forms of 

 this remarkable plant, an inhabitant of South Brazil.* 

 In the long-styled form the pistil projects above the 

 corolla, and is almbst exactly twice as long as that of 

 the short-styled, which is included within the tube. 

 The former is divided into two rather short and broad 

 stigmas, whilst the short-styled pistil, is divided into 

 two long, thin, sometimes much-curled stigmas. The 

 stamens of each form correspond in height or length 

 with the pistils of the other form. The anthers of 

 the short-styled form are a little larger than those 

 of the long-styled; and their pollen-grains are to 

 those of the other form as 100 to 67 in diameter. 

 But the pollen-grains of the two forms diiler in a 

 much more remarkable manner, of which no other 

 instance is known; those from the short-styled flowers 

 being covered with sharp points; the smaller ones 

 from the long-styled being quite smooth. Fritz Miiller 

 remarks that this difference between the pollen-grains 

 of the two forms is evidently of service to the plant j
