BOOK III. 
deep recess or sinus on each side ; as the leaves of Rumex 
pulcher. 
28. Lyre-shaped {lyratus) ; the same as panduriform, but with 
several sinuses on each side, which gradually diminish in size 
to the base ; as the leaf of Geum urbanum, Raphanus Rapha- 
nistrum. 
29. Runcinate, or hook-backed (runcinatus) ; curved in a direc- 
tion from the apex to the base ; as the leaf of Leontodon 
Taraxacum. 
30. Tapering (attenuatus) ; gradually diminishing in breadth. 
31. Wavy {undulatus') \ having an uneven, alternately convex 
and concave margin ; as the Holly leaf. 
32. Equal (cequalis) ; when both sides of a figure are symmetri- 
cal ; as the leaf of an Apple. 
33. Unequal {incequalis) ; when the two sides of a figure are not 
symmetrical ; as the leaf of Begonia. 
34. Equal-sided {(Bquilaterus) ; the same as equal. 
35. Unequal-sided {incequilaterus) ; the same as unequal. 
36. Oblique (phliquus) ; when the degree of inequality in the two 
sides is slight. 
37. Halved {dimidiatus) \ when the degree of inequality is so 
great that one half of the figure is either wholly or nearly 
wanting ; as the leaf of many Bryonias. 
C. With respect to the Apex, or Point. 
1. Kwx\c.di {aristatus) \ abruptly terminated in a hard, straight, 
subulate point of various lengths ; as the paleae of Grasses. 
The arista is always a continuation of the costa, and some- 
times separates from the lamina below the apex. 
2. Mucronate (mucronatus) ; abruptly terminated by a hard 
short point ; as the leaf of Statice mucronata. 
3. Cuspidate (cnspidatusy, tapering gradually into a rigid point. 
It is also used sometimes to express abruptly acuminate ; as 
the leaf of many Rubi. 
4. Cirrhous (cirrhosiis, apice circinatus) ; terminated by a spiral, 
or flexuose, filiform appendage; as the leaf of Gloriosa superba. 
This is due to an elongation of a costa. 
5. Pungent (^pungens) ; terminating gradually in a hard sharp 
point ; as the leaves of Ruscus aculeatus. 
6. Bristle-pointed {setosus, \ setiger^ ; terminating gradually in a 
very fine sharp point ; as the leaves of many Mosses. 
7. Hair-pointed (^piliferus) ; terminating in a very fine weak 
point ; as the leaves of many Mosses.
