74 SIR J. LUBBOCK—PHYTOBIOLOGICAL OBSERVATIONS. 
resembling the leaf characteristic of the species. We can there- 
fore have little, if any, doubt that this growth is influenced by 
the form of the leaf. 
The species in which a connexion may perhaps be traced 
between the characteristics of the leaves and those of the coty- 
ledons are so few, that I may mention here that of Embelia 
Ribes (fig. 155). The leaves are simple, alternate, exstipulate, 
Fig. 155. 
Sun 
Seedling of Embelia Ribes. Half nat. size. 
petiolate, alternately and incurvinerved, rather thick and indis- 
tinctly reticulate, shining on both surfaces, bright green above, 
paler beneath, and punctate with dark green sunken glands even- 
tually becoming blackish, thinly glandular pubescent on both 
surfaces; petioles semiterete, channelled above, closely glandular 
pubescent, tapering downwards. The first leaf is broadly ovate, 
or short elliptic, acute, and serrate except towards the base. The 
second is similar, but less broad ; the third, fourth, and fifth lan- 
ceolate, each rather narrower than the preceding. 
The cotyledons are ovate, obtuse or subacute, indistinctly 
alternately incurvinerved, and reticulate, distantly serrate in the 
upper half, petiolate and tapering into the petiole, glabrous, 
bright green and shining above, paler beneath, thinly glandular 
on both surfaces, and dotted with sunken black glands ; petioles 
semiterete, slightly furrowed above, finely glandular pubescent.
