TERMS.] VARIEGATION. 373 



4. Dotted (punctatus) ; the colour disposed in very small round spots. 



5. Clouded (nebulosus) ; when colours are unequally blended together. 



6. Marbled (marmoratus) ; when a surface is traversed by irregular veins of 

 colour ; as a block of marble often is. 



7. Tessellated (tessellatus) ; when the colour is arranged in small squares, so 

 as to have some resemblance to a tessellated pavement. 



8. Bordered (limbatiis) ; when one colour is surrounded by an edging of 

 another. 



9. Edged (maryinatus) ; when one colour is surrounded by a very narrow rim 

 of another. 



1 0. Discoidal (discmdalis) ; when there is a single large spot of colour in the 



centre of some other. 

 1 ] . Banded (fasciatus) ; when there are transverse stripes of one colour crossing 



another. 



1 2. Striped (vittatus) ; when there are longitudinal stripes of one colour crossing 

 another. 



1 3. Ocellated (pctllatus) ; when a broad spot of some colour has another spot of 

 a different colour within it. 



14. Painted (pictus) ; when colours are disposed in streaks of unequal intensity. 



15. Zoned (zonatus) ; the same as ocellated, but the concentric bands more 

 numerous. 



16. Blurred (lituratus). This, according to De Candolle, is occasionally, but 

 rarely, used to indicate spots or rays which seem formed by the abrasion of 

 the surface ; but I know of no instance of such a character. 



17. Lettered (grammicus) ; when the spots upon a surface assume the form and 

 appearance of letters ; as some Opegraphas. 



9. Of Veining. 



In terms expressive of this quality the word nerves is generally used, but very 

 incorrectly. 



1 . Ribbed (newosus, f nervatus) ; having several ribs ; as Plantago lanceo- 

 lata, &c. 



2. One-ribbed (unimemis, f wninervatus, costatus) ; when there is only one rib ; 

 as in most leaves. 



3. Three-ribbed (trinervis) ; when there are three ribs all proceeding from the 

 base ; as in Chironia Centaurium. Quinquenervis, when there are five ; 

 as in Gentiana lutea. Septemnemis, when there are seven ; as in Alisma 

 Plantago ; and so on. 



4. Triple-ribbed (triplinervis) ; when of three ribs the two lateral ones emerge 

 from the middle one a little above its base ; as in Melastoma multiflora. 

 Quintwplinervis, &c., are used to express the obvious modifications of this. 



5. f Indirecte venosus; when the lateral veins are combined within the margin, 



and emit other little veins. Link. 



6. f Evanescenti-venosus ; when the lateral veins disappear within the margin. Id. 



7. f Combinate venosus ; when the lateral veins unite before they reach the 



margin. Id. 



8. f Straight-ribbed (f rectincrvis, -\-paraUelinervis, directe venosus, Link) ; when 



the lateral ribs are straight ; as in Alnus glutinosa, Castanea vesca, &c.,
