in middle. Dorsal edge very plump, rather straight, curving mostly at apex; 
ventral ridge narrow, only slightly elevated, most prominent at base; dorsal 
suture frequently shows. Base has tendency to be slightly constricted; usually 
slightly pointed, sharply sloping; dorsal shoulder drops off suddenly near edge 
of stem scar (less than one-fourth of nut is to dorsal side of axis). Ventral 
shoulder sloping; frequently depressed. Stem scar small, oval, depressed; 
sometimes at right angles to axis or more often sloping ventrally. Apex plump, 
bluntly obtuse, wing distinct, but not prominent at apex; ventral edge much - 
curved; dorsal edge sharply curved at extreme tip; very slight blunt point 
at tip. 
Shell: Usually light brown, soft; easily cracked with fingers. Outer shell 
medium thick, brittle. Pits moderately numerous, of varying sizes, round to 
irregular, not very deep; also usually found in dorsal ridge, especially near 
apex, where they are smaller than elsewhere. Ventral edge grooved lightly; 
grooved at base, long and at acute angles to wing, especially in depressed por- 
tion. Canals small to medium, oval, quite numerous, traversing the shell for the 
most part longitudinally. Fibers small to medium. Some spongy material be- 
tween outer and inner Shell. Inner shell fairly thin, brittle, dark brown, 
marked with light-colored streaks or spots, wavy. Ventral streak frequently 
vellowish brown, sometimes dark brown, long; medium width to wide; widening 
sradually from apex to base, base bluntly round. 
Kernel: Rather large (14 by ? by 4 inches). Some doubles (12 per cent); 
fairly plump, ovate. Viewed edgewise, long ovate with straight sides, sharply 
curving at apex. Dorsal edge slightly longer than ventral and thinner. Ven- 
tral edge much curved and plump at base; dorsal edge quite straight. Fre: 
quently side has depression due to tendency to form doubles. Base slopes ven- 
trally. Dorsal shoulder square or round humped and thinner near ventral 
shoulder. Ventral shoulder roundly sloping. Apex bluntly pointed and thin. 
Pellicle usually rich brown in color, rather thin, smooth at base, slightly 
pubescent at apex; veining very distinct; base scar small, dark brown, round 
or wide oval, and frequently pubescent; pellicle fold prominent on apex half 
of ventral edge. Flavor pleasant, good, nutty, and sweet. 
Distinguishing characteristics.—Soft shell, crumbly on outer surface, ventral 
edge much curved, often depressed at base, dorsal edge nearly straight, base 
scar ventrally sloping or at right angles to axis, apex plump with ventral edge 
approaching axis almost at right angles, ridges parallel with wing common on 
ventral side; often light-colored streaks on inner surface of shell. Kernels 
frequently double and with longitudinal depression on side. 
The nut resembles in shape the Fair, Ne Plus Ultra, and Bigelow. It can 
be distinguished from these three varieties by the ridges and longitudinal 
depressions on the ventral edge parallel to the wing. 
COMMENTS 
This soft-shelled variety has an excellent flavor. It does not usually bear 
well, however, and is not recommended for further planting. 
37. IVICA 
Origin.—Ivica nuts are imported in large quantities from Spain. The variety 
is not grown in California with the exception of a few trees which bear nuts 
closely resembling the imported Ivica. These trees are probably Ivica seedlings. 
Description 
Hulled nut—(Pl. VII, BE.) Size somewhat variable, average large (13 by 1 
by & inches). 
Shape: Large, moderately long, flat, rather wide ovate. Ventral edge much 
curved, especially at apex; part at base depressed or sloping; longitudinal 
groove and ridge common; wing thick, but not prominent. Dorsal edge rather 
straight; dorsal ridge narrow and prominent. Base slightly constricted a little 
like Jordan; ventral shoulder sloping and slightly depressed; dorsal shoulder 
square, but drops off soon after leaving stem scar; stem scar large, oval, de- 
pressed, at right angles to axis or sloping slightly either dorsally or ventrally. 
Apex pointed, usually somewhat thin; wing visible, but lacks prominence; ven- 
tral edge sharply curved; dorsal edge curved or straight at apex. Extreme 
apex slightly scimitar shaped,
