244 APOSTASIA. 
ous: and differs only from the common form of pollen in 
having but one tegument. It appears to be lanceolate-ovate, 
with one or three elevated lines of a wbiter colour than the 
remaining part. Immersed in water, the lines generally dis- 
appear, and it appears like an oval or roundish vesicle, very 
transparent, containing very minute granules anda viscid 
fluid. There is no ternary or quaternary cohesion, Mr. 
Bauer’s figure of the transverse section of an anther, gives an 
idea of its having partially a double wall, or that the outer 
wall of each cell is composed of two lamine. In that I have 
examined, the parietes are simple. With respect to the 
ovula, the foramen is close to the hilum, and is distinct 
enough about the time of expansion. 
The style is recurved in a groove between the cells of the 
right anther, the connectivum of which is larger than that of 
the left. I have said right and left, the correctness of which 
may be doubted as the odd sepal, is perhaps posticous.
