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 as- 
sume the form and appearance of letters ; as some Ope- 
graphas. 
9. Of Veining. 
In terms expressive of this quality the word nerves is ge- 
nerally used, but very incorrectly. 
1. Ribbed (nervosus, f nervatus) ; having several ribs; as Plan- 
tago lanceolata, &c. 
2. One-ribbed (uninervis, | uninervatuSy costatus) ; when there is 
only one rib ; as in most leaves. 
3. Three-ribbed {trinervis) ; when there are three ribs all pro- 
ceeding from the base ; as in Chironia Centaurium. Quinque- 
nervis, when there are five ; as in Gentiana lutea. Septemnervis, 
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. Quintiiplinervis, Szc. are used to 
express the obvious modifications of this. 
5. j- 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. lb. 
7. t Combinate venosus ; when the lateral veins unite before they 
reach the margin. lb, 
8. Straight-ribbed (f rectinervis, \parallelenervis, directe venosus. 
Link) ; when the lateral ribs are straight ; as in Alnus glu- 
tinosa, Castanea vesca, &c. Mirb. When the ribs are straight 
and almost parallel, but united at the summit ; as in grasses.

9. f Curve-ribbed [\curvinervis, f converginervis) ; when the ribs 
describe a curve, and meet at the point ; as in Plantago

rupted at intervals. De Cand,
