 Great Annual Sunflower. 



Triplinerce, f. 92, triply-ribbed, when a pair of 

 arge ribs branch off from the mam one above 

 the base, which is the case in many species of 

 Sunflower or Hdlanthus, Laurus Cinnamomum 

 and Camphor a, as well as Blakea triplinervis, 

 Aublet Gulan. t. 210. 



Coloratum, coloured, expresses any colour in a leaf 

 besides green, as in Arum bicolor, Curt. Mag. 

 t. 820, Amaranthus tricolor, and others of that 

 genus, Justicia pi eta, Hedysarum pictum, Jacq. 

 Ic. Rar. t. 567 , Tradescantia discolor, Sm. Ic. 

 Plot. t. 10, Pulmonaria qfficinalis, Engl. Bot.

Variegation, variegated, is applied to a sort of 

 variety or disease, by which leaves become irre- 

 gularly blotched with white or yellow, like those 

 of Striped Grass, Arundo color at a, FL Brit. ; 

 as also the Elder, the Mentha rotundifolia, 

 Engl. Bot. t. 446, and the Aucuba japonica, 

 which last is not known in our gardens in its na- 

 tural green state. 



Nudum, naked, implies that a leaf is destitute of 

 all kinds of clothing or hairiness, as in the genus 

 Orchis. Nudus applied to a stem means that it 

 bears no leaves, and to a flow r er that it has no 

 calyx.
