2. Palmate Compound Leaves. — Such a leaf is lormed when 

 the epipodium divides into several equal or nearly equal branches, 

 each of which is separately winged ; and hence these leaves are 

 readily distinguished from those of the pinnate kind by their 

 leaflets coming off irom the same point, instead of, as in them, 

 along the sides of a common primary axis. We distinguish 

 several kinds of such leaves ; thus, a leaf is said to be hinate, 

 bifoliate, or unijugate, if it consists of only two leaflets 

 springing from a common point {fig- 153), as in Zygophyllum ;

it is ternate or trifoliate if it consists of three leaflets arranged 

 in a similaJT manner (figs. 144 and 154), as in the genus 

 Trifolium, which receives its name from this circumstance ; 

 it is quadrinate or quadrifoliate if there are four leaflets 

 {fig. 155) ; it is qidnate or quinquefoliate if there are five 

 (fig. 156), as in Potentilla argentea and P. alba; it is 

 septenate or septemfoliate if there are seven {fig. 157), as in 

 the Horsechestnut and some Potentillas ; and is muUifoliate
