In respect to form, the fruit is called oblate when its transverse diame- 
ter exceeds its axial diameter; spherical when the two diameters are 
about equal, and oval when the axial exceeds the transverse diameter. 
It is said to be hemispherical when the contour of a section through the 
axis approaches a semi-circle, and pyriform when it is pear-shaped. 
The outline of the fruit means the contour of a transverse section 
through its center. The outline is said to be angular when the con- 
tour is distorted in obscure angles, and corrugated when it bends into 
scallops or folds. It is regular when it exhibits neither angles nor 
corrugations, but approaches a circle. 
The cavity and basin have the same significance as in pomology, i. e., 
the former representing the depression about the stem, and the latter 
in the opposite part of the fruit. The basin is said to be ringed when 
it is bounded by a more or less distinct and regular corky ring, and 
fissured when it contains distinct irregular depressions reaching nearly 
or quite to the center of the fruit. 
The center of the fruit is said to be well filled when the cells are 
chiefly disposed about the outside, leaving the center largely occupied 
with the pulp. 
The terms applied to the foliage are used in their strict botanical 
sense. 
The flavor of the fruit is not often specified, as I have been able to 
detect little difference in this respect except as between fruits of dif- 
ferent color. The fruits of the white and yellow varieties are less acid 
than those of the scarlet ones, and those of the purplish red tint are in 
general rather harsher in taste than those of other shades. But with 
a very few exceptions, other differences have not seemed sufficiently 
marked for specification. 
Analytical Key. 
As an aid in naming varieties, the following analytical key is 
arranged : 
1. Plant strongly scented, stem hairy, leaves unequally one to two 
pinnate (Ly coper sicum esculentum). 
A. Stem weak; plant decumbent. 
a. Leaflets numerous, toothed, more or less pinnate 
(var. vulgar e). 
*. Fruit more than two-celled, with a more or 
less distinct cavity about the stem. 
J. Fruit deep scarlet. 
§. Outline angular or corru- 
gated. Nos. 1-24, incl.
