8. Pinnate (pinnatus)\ when simple leaflets are arranged on 
each side a common petiole ; as in Polypodium vulgare. 
9. Pinnate with an odd one (impari-pinnatus) \ when the petiole 
is terminated by a single leaflet or tendril ; as in Pyrus aucu- 
paria. If there is a tendril, as in the Pea, it is called 
cirrhose. 
10. (^pari-pinnatus^ abrupte pinnatus^ \ when the 
petiole is terminated by neither leaflet nor tendril ; as Orobus 
tuberosus. 
11. f Alternately pinnate (^-\ alternatim pirmatus) \ when the leaf- 
lets are alternate upon a common petiole ; as in Potentilla 
rupestris. Mirb. 
12. Interruptedly pinnate ( 2 when the leaflets 
are alternately small and large ; as in the Potato. 
13. f Decreasingly pinnate decrescente pinnatus)\ when the 
leaflets diminish insensibly in size, from the base of the leaf 
to its apex ; as in Vicia sepium. Mirb. 
14. f Decursively pinnate (f decursive pinnatus) ; when the petiole 
is winged by the elongation of the base of the leaflets ; as in 
Melianthus. Mirb. This is hardly different from pinnatifid. 
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. 
16. Twin digitato-pinnate {bidigitato-pinnatus^ bicovjugato-pin- 
natus) ; the secondary petioles, on the sides of which the
