A fpear-iharped leaf [lanceolatiim) is fliaped 

 like the point of a fpear ; it is oblong, and gra- 

 dually narrowed from the middle to both" 

 ends, where it ends in points, as in the narrow^^ 

 leaved Plantain, &c. fee fig. 6. 



A linear or narrow leaf {Uneare) is that, 

 which commonly is narrowed toward the two 

 ends, but the fides are parallel its whole length, 

 as Rofefnary, &c. fee fig. 7. 



An awl-(haped leaf (fubulafiim) is fomewhat 

 like the former on its upper furface, but the 

 under part is thicker in the middle, growing 

 narrower to a point at the top, like the point 

 of an awl, as in the Mefemhryanthemum fca-- 

 hrim, Lin. fee fig. 8. 



A triangular leaf {iriajigulare) is one with 

 three redangular fides, and three angles, the 

 two lower being even with the bafe, as in the 

 MefembryanthemumbelUdijloriimy fee fig. 12. 



A deltoide leaf {deltoides) is one with four 

 angles, the two at the top being at a greater 

 diftance from the center, than thofe of thj3 

 fides, as in the SeaOracb^ fee fig. 58. 



A quinqueangular or five cornered leaf 

 {quinqiie angular e) is one whofe fides are ftrait 

 to the middle and are not broken, as in that 

 of Lavateria Olbia^ fee fig, 20. a^ b, this fome-
