In one case I found a poorly developed gland on the tip, 
pointed trichome in an adult leaf, but this, though a very iz 
intermediate stage, is certainly an exceptional occurrence. Asa 
these points are well developed early in the ontogeny of the | 
it seems very doubtful whether each one passes through 4 | 
glandular stage in its development. 
As regards the small glands still present, it may be pretty 
concluded that they are a somewhat retrograde condition of 
tive glands. One of such retrograde glands is represented in fg 
of equal relative size with the other figures of trichomes. These 
of much more frequent occurrence on the petiole, where aso 
stalked glands persisted longest unmodified, than on the lamina. its 
also worthy of note that they reach their highest development # 
earlier period in the unfolding of the leaf than do thet 
points, another fact which gives evidence of their direct 
a primitive structure. —CARLETON E. Preston, Harvard Univ
