evenly rounded at the tip or sometimes truncate or subcordate, 25 to 
72 by 12 to 33 mm., usually 35 to 60 by 20 to 30 mm., the wingless 
basal portion being 4 to 5 mm. long and 1^ to 2 mm. in diameter. The 
blades are ovate acuminate or elliptical acuminate, evenly rounded or 
very bluntly pointed at the base and narrowed into a more or less acumi¬ 
nate or caudate apex, which is, however, abruptly rounded and usually 
emarginate at the very tip, 20 to 66 by 13 to 30 mm., usually 30 to 60 
by 18 to 30 mm. (See PI. I and figs. 6 and 7.) The petioles and 
laminae have rather numerous slender secondary veins that run nearly 
parallel and rather straight almost to the margin, making an angle 
with the midrib varying from about 45 0 to nearly 90°. (See fig. 5.) The 
internodes are 12 to 30 mm., usually 15 to 20 mm., long. 
The flowers are borne singly in the axils of the leaves (alongside of 
the spine when present); they seldom occur at the end of the twigs. 
The flower buds are cylindric or subcylindric, with a hemispherical tip and 
a truncate base, all parts being very prominently glandular dotted. (See 
figs. 4, 6, and 7.) The pedicels are short and slender, 4 to 6 mm. long, 
1 to 2 mm. in diameter, prominently glandular dotted, with a few very 
small bracts near the base. The calyx is fleshy, 4 to 6 mm. in diameter; 
the sepals are subtriangular, 3 by 3 mm., thick and fleshy, margins 
minutely ciliate. The corolla is white; when fully open it is about 25 to 
30 mm. in diameter, with cylindric-oval petals 12 to 18 mm. by 8 to 10 
mm. wide, and 20 stamens 8 to 10 mm. long cohering almost the whole 
length but separating into a few bundles in fully developed flowers. The 
anthers are 2 to 3 by 1 to 1^ mm. in size. The pistil is about 10 mm. 
long, stout, on a cushionlike disk 2% mm. high and 4 mm. in diameter, 
with a subglobose ovary 4 by 4 mm. The style is stout, 4 mm. long, 1 to 
1X mm. in diameter, caducous, leaving a very short basal portion attached 
to the fruit. The stigma is large, subglobose, 2 to 3 mm. in diameter, 
almost as large as the ovary, which is 8 to 11 celled, with numerous 
ovules in each cell. (See fig. 1, A.) 
The fruits are subglobose, slightly longer than wide, 8 to 11 cm. (3 % to 
4^ inches) long, 7 to 10 cm. {2% to 4 inches) in diameter, with a wrinkled 
and furrowed base and an inconspicuous, very low, and broad papilla at 
the top, tipped with the persistent base of the style and delimited by a 
shallow circular furrow, making a circle about 20 to 35 mm. in diameter, 
usually 25 to 30 mm. (See fig. 2.) The fruits look like very large, 
short and thick lemons. 
The peel is rather rough, resembling that of a large lemon, 6 to 10 mm. 
thick, usually 7 to 9 mm. There are from 8 to 11 segments. In a large 
11-celled fruit (Wilson No. 4737) the segments are 72 mm. long, 25 to 
35 mm. wide, and 20 mm. thick; in a small 8-celled fruit (Wilson No. 
4736) from the same locality they are 60 mm. long, 25 mm. wide, and 
18 to 22 mm. thick.
