a.) 75. Cuticular (reliquium cuticulare) having 

 received its form from the cuticle or epidermis 

 of the vegetable. 



next to the ligament (margo anterior* Linn.) and the upper 

 part or margin opposite to the hinge (margo superior. Linn.) 

 Entire (integer) without indentations of any kind. 

 Sinuate (sinuatus) with a bending or indentation in the upper 

 part of the margin as in many species of anomitce. The 

 term is also applied to the valves (raha sinuate?) when the 

 sinus or bending of the margin is continued by a channel 

 or groove (canalis) up one valve, with a corresponding con- 

 vex wave or ridge (lira) down the other. 

 THE SINUS (sinus) differs according to the margin and the ridge 



and channel. 

 * Margin. 

 fl.)Large (magnus) \\ hen it occupies not less than one half of the 



upper margin. 

 Small (parvus) when it does not extend through more than one 



third of the upper margin. 

 Long (longus) when tne depth of the sinus at the margin ex-* 



ceeds its breadth. 



Obsolete (obsoletus) scarcely distinguishable at the margin. 

 &.)Angular (angulatus) forming an angle at the margin. 



Rounded (rotundatus) forming a curve without any angle or 



break ; not angular. 



Cuneiform (cuneiformis) long, and ending 'in an acute angle. 

 Obtuse (obtnsus) rounded ; but fonning only a small segment 



of a circle. 



Truncate (truncatus) ending in a straight line at the margin 

 so that the sinus has somewhat of a square appearance or 

 seems as if it had been cut off, where it would otherwise 

 have formed a curve. 



rJPiaited (pUcatus) with large, angular indentations at the mar- 

 gin. 

 Waved (undatus) with large, obtuse or rounded indentation*
