15. Digitato-pinnate (digitato-pinnatus) ; when the secondary petioles, on the 

 sides of which the leaflets are attached, part from the summit of a common 

 petiole. Mirb. 



12 9 16 



10 23 



16. Twin digitate -pinnate (bidigitato-pinnatus, biconjugato-pinnatus) ; the 

 secondary petioles, on the sides of which the leaflets are arranged, proceed 

 in twos from the summit of a common petiole ; as in Mimosa purpurea. 



1 7. Bigeminate (biff&wnahu t biconjugatiis) ; when each of two secondary petioles 

 bears a pair of leaflets ; as in Mimosa unguis Cati. Mirb. 



18. Tergeminate (tergeminus) ; when each of two secondary petioles bears 

 towards its summit one pair of leaflets, and the common petiole a third 

 pair at the origin of the secondary petioles ; as hi Mimosa tergemina. 



1 9. Thrice digitate-pinnate (f tridigitato-pinnatus, ternato-pinnatus) ; when the 

 secondary petioles, on the sides of which the leaflets are attached, proceed 

 in threes from the summit of a common petiole ; as in Hoffmannseggia. 



20. f Quadridigitato-pinnatus t as in Mimosa pudica, and f Multidigitato-pin- 

 natus, are rarely used, but are obvious modifications of the last. 



21. Bipinnate (bipinnatus, f duplicato-pinnatus) ; when the leaflets of a pinnate 

 leaf become themselves pinnate ; as in Mimosa Julibrissin. 



22. Bitemate (biternatus, f duplicato-ternatus) ; when three secondary petioles 

 proceed from the common petiole, and each bears three leaflets ; as in 

 Fumaria bulbosa, Imperatoria Ostruthium, &c. Mirb. 



23. Triternate (tritematus) ; when the common petiole divides into three 

 secondary petioles, which are each subdivided into three tertiary petioles, 

 each of which bears three leaflets ; as the leaf of Epimedium. 



24. Tripinnate (tripinnatus) ; when the leaflets of a bipinnate leaf become them- 

 selves pinnate ; as in Thalictrum minus, or CEnanthe Phellandrium. 



25. Paired (conjugatus, unijuyus, f imijugatus) ; when the petiole of a pinnated 

 leaf bears one pair of leaflets ; as Zygophyllum Fabago. Bijugus is when 

 it bears two pairs ; as in Mimosa fagifolia : trijugits, quadrijugus, quinque,- 

 jugus, &c., are also employed when required. Multijugus is used when 



the number of pairs becomes very considerable ; as in Orobus sylvaticus.
