SIR J. LUBBOCK—PHYTOBIOLOGICAL OBSERVATIONS. 69 
and 148 show, that the new growth has a distinctly foliar 
character. 
In @Enothera Lindleyana and E. amena the development is 
very similar to that of Clarkia gaurioides. (Œ. tenella belongs 
also to this group.

The same is the case with the earlier stages in Clarkia integri- 
petala ; but in this species, while the original cotyledon is all but 
glabrous, the foliar portion resembles the leaves in being conspi- 
cuously pubescent on the upper surface. The passage from the 
one portion to the other is abrupt; and, the veins being also 
‘well-marked in the foliar part of the cotyledon, the contrast 
between the two regions is very conspicuous. 
` In Eucharidium concinnum the cotyledons follow a similar 
Course of development; but the upper surface of the original 
cotyledons are glandular, though less conspicuously so than the 
foliar portion. The passage also is less abrupt. The foliar
