leaf has a terminating foliole or leafit; as in the fervice.tree. 
16. Pinnated alternately, when the leafits or folioles come 
out on each fide one after another ; as in indigo.

cepted vvith fmaller leafits between ; as in agrimony. 
18. Pinnated with a cirrhus, when a pinnated leaf ter- 
.wiuiates with a tendril; as the garden pea. 
u). Pinnated articulately, when the petiole or (lem of a 
ffinnated leaf is articulated, and the leafits fpring from the 
articulations; as fagara tragodes. 
20. Pinnated decurfivcly, when the bale of the folioles 
*re continued on the fides of the petiole or footflalk of a pin¬ 
nated leaf running down the (tern; as in the honey-flower. 
—Pinnated doubly, when the petiole of a pinnated leaf 
bears pinnated wings; as in fig. 3, and 4. 
21. Pinnated triply, or triplicate, when the petiole of a

Fig. 22. Qmnated, when a digitated leaf has five fo¬ 
lioles ; as the bramble or blackberry. 
23. Supra-decompofite, when many leafits are united oh 
a many-times divided petiole or footflalk ; as the yellow 
fumitory. 
24. Ternate, with the folioles petiolate, when a com¬ 
pound leaf has three petiolated folioles upon one petiole ; 
as the African fumach. 
25. Ternated (elfile, when the leafits grow immediately 
to the (lem, without any petiole; as the pigeon pea. 
26. Ternated doubly, when three folioles are let on one 
petiole, and each petiole is ternate; as in barren-wort. 
27. Ternated triply, when one petiole bears three fo¬ 
lioles, and each of the folioles is ternate ; as in the berry¬

Figures of the Determinate Leaves. 
Fig. 1. Apprefled, the di(k of the leaves prefitng or 
turning towards the (lem ; as in mithridate muflard .—See 
the annexed engraving. 
2. AdverCe, when the leaves turn towards the fouth, 
and not towards the (ky; as ginger. 
3. Alternate, when the leaves, inflead of growing out in 
pairs, are let one above another, in oppofite directions; as 
the African kiggelaria. 
4. Amplexicaiil, embracing the (lem, when the bafe of 
the leaf entirely (iirrounds the (lem tranfverfely; as the 
white hellebore. 
5. Approximate, when many leaves occupy the fame 
branch, lb as to leave fcarcely any fpace between them ; 
as the berry-bearing yew. 
6. Axillary, when the leaves grow out of the angles 
formed by the branches and the Hem ; as parthenium or 
feverfew with entire leaves. 
7. Bifarious, when the leaves diverge, or point from op¬ 
pofite fides; as the filverfir.—Bradtne, or floral leaves, are 
fucli as accompany the flowers; feefig. 17.—Cauline, leaves 
growing immediately on the (lem, without any petiole or 
footflalk; as in fig. 6. 
8 . Coma, orbufhy ; when a bunch of leaves terminate 
the ftalk, or flowering (lem ; as in the crown imperial. 
9. Connate, when two oppofite leaves grow together, 
or unite at the bafe, Co as to have the appearance of one 
leaf; as in laciniated teazel. 
10. Decurrent, or running down ; when the bafe of a 
felFile leaf extends itfelf downwards along the (lem, beyond 
the proper bale or termination of the leaf; as in peach¬ 
leaved campanula. 
11. Decollate, leaves divided in pairs, each pair grow¬ 
ing alternately on oppofite fides of the flem ; asOfwego tea. 
12. Demerfed, in aquatic plants, leaves funk below the 
furface of the water ; as the water-violet. 
13. Dependent, or hanging down ; leaves whofc apex 
points diredlly to the ground ; as moving French lioncy- 
iuckle. 
14. Diflich, leaves growing in two rows or lines, from 
the bafe to the apex ; as the deciduous cyprefs. 
15. Erect or upright, when the leaves form an acute angle 
with the ilem ; as corn-marigold with fpear-fliaped leaves. 
16. Fafciculated, many leaves grow ing in a tuft from 
the fame point ; as in the larch-tree. 
17. Floral; the bradjhc, or leaves that are annexed to, 
or grow near upon, the flower ; as in large-leaved rheo- 
broma, or chocolate-nut-tree. The leaves on the top of

18. Imbricated, growing together ere it, and mutually, 
covering each other like tiles; as in common cyprefs-rree. 1 
19; Index, the leaves bending inwards towards the
