more than seven (fig. 369), as in many species of the Lupin. 
The term digitate is sometimes employed to characterise a com- 
pound leaf of five leaflets, but this name should be confined to 
a simple leaf, and used in the sense already noticed (page 168).

sense, they are also commonly, although improperly, termed 
palmate or digitate ; but when the leaflets of a palmately-veined 
leaf are arranged in a pedate manner, the leaf is properly termed 
pedate (page 168). 
Palmately-veined compound leaves may become still more 
divided. Thus, if the common petiole divides at its apex into 
three partial ones, each of which bears three leaflets (jig. 370), 
as in the Masterwort (Imperatoria Ostruthium), the leaf is 
termed biternate; or when the common petiole divides at its 
apex into three partial ones, and these again divide into three 
others, each of which bears three leaflets, as in the Yellow 
Fumitory (Corydalis lutea) and Epimedium, the leaf is triternate 
(fig. 871); or when such a leaf is still further divided, it is said 
to be decompound,
