definitely what its bearing habits will be, the character of the fruit 
is so unusual as to make it worth while to test the variety in the 
United States. Most round avocados have medium-sized or large 
seeds. This one, however, has an unusually small seed, and if it 
proves desirable in other respects it will be well worth cultivating. 
In quality it is good. 
The parent tree is growing in the finca La Candelaria in Antigua. 
The elevation is approximately 5,100 feet. The tree has been planted 
to shade coffee bushes and is still young, its age not being more than 
5 or 6 years. It is tall and slender in habit, about 20 feet high, with 
a trunk 6 inches thick at the base. As is customary in fincas, the 
tree has not been allowed to branch low, the first branches being 
more than 6 feet from the ground. The growth looks unusually 
strong and healthy, the young branchlets being stout, long, stiff, and 
well formed. The bud wood is excellent, having the vigorous buds 
well placed. 
Little can be determined regarding the flowering and fruiting 
habits of the tree at this early day. When it was first seen, early 
in May, 1917, it had only three fruits on it. It may have borne 
more, as the crop had already been harvested from most of the trees 
in the finca. The ripening season is probably March to May. 
The hardiness of the tree can not be determined until it is tested 
in the United States, as it is never very cold at Antigua. 
The fruit is round, about a pound in weight, green, with a mod- 
erately thick skin. The flesh is of good color and quality, and in 
quantity much greater than in the average round avocado, since the 
seed is quite small. 
The variety may be described as follows : 
Form oblate; size medium, weight 16 ounces, length 3* inches, breadth 3| 
inches ; base slightly flattened, the long slender stem inserted without depres- 
sion almost in the longitudinal center of the fruit ; apex flattened, slightly de- 
pressed around the stigmatic point; surface pebbled, deep yellow green in 
color, with numerous minute yellowish dots ; skin not very thick for this race, 
one-sixteenth of an inch or slightly more, hard, granular toward the flesh; 
flesh cream colored around the seed, becoming pale green close to the skin, 
very slightly discolored, with brownish fiber tracing, but with no fiber; flavor 
rich and pleasant ; quality very good ; seed very small for a round fruit, oblate, 
weighing less than 1 ounce, tight in the cavity, with both seed coats adhering 
closely to the cotyledons. 
TERTOH. (No. 30.) S. P. I. No. 44856. 
The Tertoh avocado is a famous variety from Mixco, near the city 
of Guatemala, noted for its immense size and excellent quality. 
(PL XXII.) 
The parent tree is growing in the sitio of Leandro Castillo, just 
above the plaza of Mixco, at an elevation of approximately 5,700 feet.
