FOR FORMS AND QUALITIES. 45 



Notches are blunt rounded teeth. The margin is called 

 crenated (crenatus), when it has indentations of this sort. 

 Varieties of the crenated are \\\q fmely-crcnated {cremdatus), 

 and the crcnated-dentated (crenato-dcntatus)^ when the notch 

 is not completely rounded, but is not properly pointed. 



Cilia are hairs, or bristles, which divide the margin. The 

 margin is then called ciliatus ; (Tab. VI. Fig. 11.) The 

 hairs frequently rise from sharp teeth, on which account the 

 margin is then said to be serrato-ciUatus. The hairs are 

 sometimes so stiff, and at the lower extremities so broad, that 

 they might be taken for spines or thorns. The margin is 

 then said to be ciliato-aculeatus, or spinoso-ciliatus. Some- 

 times the hairs have other round bodies, or glands, on their 

 points, the margin is then called gianduloso-cillatus ; (Tab. 

 VII. Fig. 1. 4.) 



When fine fringes, in the form of cilia, extend themselves 

 from the surface, \hQ \(\e2i o^ fringed {JimhriaUis), is gene- 

 rated.

With respect to the unseparated parts of a surface, we 

 have the following definitions. 



Large unseparated parts, which are broad and rounded, 

 are called lobes (lohi). When they are small and pointed, 

 they are calledyrm^^^ {lacinia). 



Hence we use the expression lobed {lohatus), when, in ge- 

 neral, there are lobes, without denoting their number ; thus, 

 also, three-lobed {trilobus), four-lobed {quadrilobus), and so 

 forth. 



When a part has lacinia, it is said, in general, to be cleft 

 (laciniatus), when the number of clefts is not mentioned ; 

 but, when these are counted, we observe whether the cleft 

 proceeds to the centre, or almost to the base. In the former 

 case, we say of the part, that it is tri- quadri- qinnqu€-fidum. 

 If the clefts go almost to the base, we call the part tri- quadri- 

 quinque-partiius. This distinction is chiefly important re- 

 specting the calyx.
