Explanation of Terms. 201 



gradually tapering down instead of up ; egg-shape, when 

 it is of the general shape of an egg, with the broadest part 

 below the middle, but without regard to the form of the 

 base and the apex ; inversely egg-shape, when it is the 

 shape of an egg, but with the broadest part above the 

 middle ; oval, with the broadest part at the middle. 



(4) The leaf at its apex may be pointed, taper-pointed, 

 bristle-pointed, blunt, or rounded. 



(5) The leaf at its base may be squared, rounded, 

 pointed, wedge-shape (when it tapers to a point by straight 

 lines), or heart-shape. 



(6) The leaves as arranged upon the branch may be 

 alternate, when they follow one another upon different 

 sides of the branch ; opposite, when they are in pairs and 

 on opposite sides of the branches ; indeterminate, when 

 they are small and closely crowded up and down the 

 branches, e. g., the club-mosses. 



(1) Stipules are appendages of the nature of a leaf, but 

 of various forms, found in some plants in pairs at the base 

 of the leaf-stems, e. g., in the Pea. 



(2) Stipels are small stipules found in some plants at 

 the base of the leaflet-stems. 



(3) Bracts are small appendages of the nature of a leaf, 

 but of various forms, found oftenest in connection with, or 

 just below, the calyx. 



(4) The axil of a leaf is the angle between the leaf- 

 stem and the branch.
