17, dorsal shoulder ; 18, outer shell; 19, inner shell; 20, pellicle fold 
Acute. Ending in a sharp point. Used in reference to leaves, nuts, buds, and 
lenticels. See apex of Long I. X. L. leaves (Pl. XXV, A) and apexes of 
Malaguena Jordan lenticels (Pl. XVI, C). Widely acute, broadly acute, or 
bluntly acute. See apex of Hudson leaf (Pl. XXIII, A) and apexes of 
Tarragona lenticels (Pl. XVII, £). 
Acute angled. Having acute angles. Used in referring to the angles which 
branches make with each other where they join. 
Apex. The tip or end. Used to indi- 
cate the end of the nut, leaf, or bud 
opposite the end attached to the stem, 
and also the ends of lenticels. (Fig. 5 
(6); fis) G) and tis.W Ge) 
Appressed. Flattened against or 
pressed against another body. Used 
in reference to buds pressed against 
twigs or spurs. 
Axis. A straight line through the cen- 
ter of the nut, extending from the 
center of the stem sear to the point 
of the apex. Used with reference to 
the nut while in the hull on the tree, 
the nut when hulled, and the kernel- 
When used with reference to the ker- 
ca nel, the line passes from the center 
APEX of the base scar to the apex. (Fig. 5 
(10) and fig. 6.) 
Base. The attached end. Used in ref- 
erence to nut, bud, leaf blade, and

Fic. 6.—Reams almond in hull before si the leaf. (Fig. 7, a.) be 
dehiscence, showing axis, ventral edge, oom. A fine powder or waxy dust 
dorsal edge, style, base, and apex which sometimes whitens leaves or 
twigs. 
Branching angle. The angle at which branches join. (See Acute and Ob- 
tuse. ) 
Bristle. The projecting ends of the veins in the depressions of the serrations 
or crenations of the leaves.
