 divided. .nearly to the base, 

 as Helleborus viridis : and 

 according to the number of 

 its divisions it is bipartite, 

 tripartite, or multipartite. 



A multipartite leaf 

 folium multipartitum 

 (figure 56). (From the 

 Latin, multus, many ; and 

 pars, part much divided.) 

 Having very deep and very distinct divisions. 



A laciniate leaf folium laciniatum 

 (fig* 57)* (From the Latin, lacinia, 

 a lappet; a separate fold of a garment.)

EXAMPLES OF COMPOUND LEAVES. 

 Compound leaves may be referred to two classes or divisions ; 

 one containing digitate, and the other pinnate leaves, accordingly 

 as they are supposed to resemble fingers (digitus) or feathered 

 stems (pinnatus). First, of digitate leaves : 



A conjugate or binate leaf (fig- 58). 

 (Conjugate, from the Latin, conjugatum, 

 which is formed from con, together, and 

 iugum, a yoke, yoked together. Binate, 

 from the Latin, bis, two, and natus, grown.) 

 When a common petiole bears two leaflets on
