and the radicle has less space to develop. The first two 

 leaves are opposite as in many previously mentioned species, 

 lanceolate and serrate ; but in vigorous seedlings a pair of 

 lobes is developed at the base. The second pair are digitately 

 tripartite with lanceolate, serrate divisions, the middle one of 

 which is much the largest. The third and fourth pairs are 

 digitately four- to five-partite with lanceolate segments ; and 

 the ultimate leaves have numerous lanceolate, acuminate, 

 radiating segments. The cotyledons of C. gigantea are downy, 

 but otherwise similar to those of C. sativa. The first two 

 leaves are lanceolate-oblong, while the second pair are deeply 

 tripartite at the base, with the terminal segment much the 

 largest. 



The cotyledons of Girardinia heterophylla differ from those 

 of Cannabis in being relatively wider, emarginate, petiolate 

 and alternately penninerved, and from Urtica dioica in shape, 

 venation and their much greater size. The two primordial 

 leaves are opposite, oblong and coarsely serrate. The coty- 

 ledons of Forskohlea viridis are relatively narrower than those 

 of the last, and pubescent, but otherwise resemble them. The 

 two first leaves are opposite, lanceolate and distantly serrate. 



The seventh type is represented by Humulus japonicus, 

 which has linear, obtuse, or acute cotyledons, slightly connate 

 at the base, and showing a sunk midrib only. They are also 

 finely glandular-pubescent, equal in length, and 2-8-3 cm. 

 long by 2*5-3 mm. wide. The stipules are interpetiolar, and 

 the two from adjoining leaves are connate into one blunt piece. 

 The two first leaves are trifid, and the two following five-lobed 

 and five-nerved. 



Celtis occidentalis, L. 



Pistil syncarpous, superior ; ovary one-celled, one- sometimes two- 

 ovuled, surmounted by the deeply bi-fid or -partite style ; ovules 

 subapical, pendulous, campylotropous, collateral when two are 

 present ; radicle dorsal, superior, close to the apex of the cell, 

 elongated. 



Fruit a rather fleshy berry or drupe, ovoid, slightly oblique and 

 tipped with the short, persistent, hardened base of the style, one- 

 celled, one- sometimes two-seeded, deep green when young, becoming 

 pale or yellowish ultimately slightly reddish, glabrous ; rnesocarp
