INDIVIDUAL ABSOLUTE TERMS.

down to half the breadth of the leaf : 2. pinnatipartitus, 
when the lobes pass beyond the middle, and the parenchyma 
is not interrupted : 3. phmatisectus, when the lobes are di- 
vided down to the midrib, and the parenchyma is interrupted: 
4. pin7iatilobatus, 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, palmatipartitus, palmatisectus, pahnatilohatus ; and peda- 
tifidus, pedatipartitus, pedatisectuSi dLudi 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. 
5. Supradecompound (supradecomposifus') ; having various de- 
compound divisions or ramifications. In leaves it is applied to 
such as have the primary petiole divided into secondary ones, 
and the secondary into a third set ; as in the leaf of Daucus 
Carota. 
6. f Bifoliolate (f bifoliolatus, binatus) ; when in leaves the com- 
mon petiole is terminated by two leaflets growing from the 
same point ; as in Zygophyllum Fabago. This term has the 
same application as unijugus and conjugatus. We say trifo- 
liolate, or ternate, when the petiole bears three leaflets from 
the same point ; as in Menyanthes trifoliata: \ quadrifoliolate, 
if there are four from the same point ; as in Marsilea quadri- 
folia : and quinquefoliolate, or quinate, if there are five from 
the same point ; as in Potentilla reptans : and so on. 
7. f Vertebrate (fi vertebratus) ; when the leaf is contracted at 
intervals, there being an articulation at each contraction ; as 
in Cussonia spicata. Mirb,
