down to half the breadth of the leaf ; 2. pinnatipartitus, 
when the lobes pass beyond the middle, and the parenchyma 
is not interrupted ; 3. pinnatisectus, when the lobes are di- 
vided down to the midrib, and the parenchyma is interrupted ; 
4. pinnatilobatus, when the lobes are divided to an uncertain 
depth : lyrate and the like belong to this modification. He 
has similar variations of palmatus and pedatus ; viz. palmati- 
Jidus, palmatipartitusy palmatisectus, palmatilobatus ; and peda- 
tifidus, pedatipartitus, pedatisectus, and pedatilobatus. 
12. Comb-shaped (^pectinatus) ; the same as pinnatifid ; but the 
segments very numerous, close, and narrow, like the teeth 
of a comb ; as the leaf of Lavandula dentata, all Mer- 
tensias. 
C. With respect to composition or ramification. 
1. Simple (simplex) ; scarcely divided or branched at all. 
2. Quite simple (simplicissimus) ; not divided or branched 
at all. 
3. Compound (compositus) ; having various divisions or ramifi- 
cations. As compared with the two following, it applies to 
cases of leaves in which the petiole is not divided ; as in the 
orange. 
4. Decompound (decompositus) ; having various compound divi- 
sions or ramifications. In leaves it is applied to those the 
petiole of which bears secondary petioles ; as in the leaf of 
Mimosa purpurea.
