NOMENCLATURE. 



Chartaceous {chartaceus), is a firmer variety of the former, 

 as in the fruit-cover of the Notolgena, Venten. 



Inflated {inflatus), when a part has thin extended sides, 

 and is internally hollow. Calyx irtflatits Silenes Hermanniae ; 

 Faux hiflata Dracocephali. An inferior degree of this is ven- 

 tricose, (ventricosus). 



Crustaceous {crustaceus,Jragilis), when a part is dry, and 

 is composed of small pieces or scales ; as in the Peridise of 

 Physarum, and the fruits of Leucopogon, R. Br. 



Dry {exsuccus), is used chiefly with regard to fruits, and is 

 opposed to juicy, (pulposus, or succulentus). 



Bony (osseus), or stony (lapideus), denote the highest de- 

 gree of hardness ; as in the fruit of Scleria, Lithospermum, 

 Styphelia, and Ventenatia, Cav. 



Cartilaginous (cartilagineus), is an inferior degree of hard- 

 ness, but which still allows the parts to be separated with dif- 

 ficulty ; as the margins of many leaves, and the albuminous 

 parts of seeds. 



Cork-like {suherosus), and spongy (spongiosus), explain 

 themselves. 



Leathery (coriaceus), expresses the union of a certain de- 

 gree of hardness with elasticity, as in many leaves, and in the 

 corolla of many Styraceae. 



Horny (corneus), is something harder than the cartilagi- 

 nous. It is applicable chiefly to seeds. 



If we attend to the substantial configuration of the Organs, 

 we employ the following expressions. 



A part is said to be round (teres, cylindricus), of which 

 the section is more or less circular. From the gradations of 

 this form, there arise the ideas of half-round (semiteres), and 

 , roundish (teretiusculus). If the cylindrical body is very fine, 

 it is called capillaceous {capillaceus, 16.), or Jiliform, (fili- 

 Jbrmis) ; in which last case, the thickness may be somewhat 

 greater, and the section does not always exhibit a circle. 



Compressed {comprcssus), when the body has two flat sur- 

 faces, Avhich meet in projecting angles. When these angles
