 clearer o-reen, it is called aruginosus. Prasinus is a slight 

 variety of it, with which a little ash-grey is mixed.

The surface of the parts has sometimes no covering, and' 

 no })roniinent substances. It is- then called even (Iwvis). A 

 higher degree of this evenness is denominated &Jiming {niti- 

 dus. The liig-hest deo:ree, which exhibits the surface a.s a 

 mirror, is called lueid or splendent (luddus, spkndens) ; and 

 when there is at the same time a gloss upon the part, it is 

 said to be veniicosus. Opake {opacns) is the op{X)site of 

 lucid, as it is also of transparent, (23.) 



The want of hairs, or of substances resembling hairs, con- 

 stitutes the surface smooth (glahei'.) The term mains is also 

 used, to express the want of hairs or of a covering. 



Surfaces that are uniformly even are called ccqualnles: 

 tiiose that are not uniform, but which have pi ominences and 

 hollows, although they are at the same time smooth, are-said 

 to be incequahilcs,

With respect to tlie hairs in particular, they are in general 

 called pubes, and pubescens denotes a gentle and almost indis- 

 tinguishable covering of hairs. Soft {mollis^ moIUssimus) is 

 nearly the same. 



If the hairs are soft, somewhat long and bent, the covering 

 is said to be pilosus ; but it is denominated viUosus or shag- 

 gy, when the soft hairs stand parallel and erect. 



When the hairs, again, have other hairs attached to them, 

 the idea of plumes is generated (plumosus). In Hieracmm 

 undulatnm^ Ait. the whole surface is covered with these. lu 

 Damplera^ R. Br. the hairs of the whole are plumose.
