or humped dorsal shoulder; and abundant, short pubescence. The I. X. L. 
nut is distinguished from the nuts it resembles by the base, which is commonly 
sloping ventrally or at right angles to the axis. It resembles in shape the 
Batham, Henle, Smith, and Trembath. For points of difference between it 
and Batham and Henle, see distinguishing features under those varieties. 
The I. X. L. is easily distinguished from the Smith by the shorter and wider 
kernel, which lacks the deep longitudinal crease so common in the side of the 
Smith kernel. 
The I. X. L. kernels are shorter and very much less pubescent than the 
Trembath kernels, and the dorsal shoulder of the I. X. L. kernel is square or 
humped while in the Trembath the dorsal shoulder is round. 
COMMENTS 
There was a period in which it was difficult to market the entire crop of 
I. X. L. almonds, but at present it is one of the best sellers to the market 
for unshelled nuts, and there is little danger of overproduction. The nut is 
large, regular, and, in general, attractive in appearance. From the growers’ 
standpoint the variety has proved on the whole unsatisfactory. It is subject 
to injury by spring frosts because of its early blooming (February 10 to 
March 15, depending on locality and season), is a very light bearer in most 
localities, produces many gummy nuts, and in some seasons most of the nuts 
are sticktights. It does well in the Banning district in southern California 
and in the foothill sections west of the Sacramento River. In most other dis- 
tricts the variety has not paid the growers for the cost of production. For 
this reason many growers have grafted their I. X. L. trees over to other 
varieties, or to other fruits, or have converted the trees into firewood. Further 
plantings of the variety are not to be recommended except in the most favor- 
able localities. It is a good pollinizer for the Ne Plus Ultra, but the I. X. L. 
and Nonpareil will not pollinize each other. The I. X. L. tree is less susceptible 
to disease than some other varieties. 
OTHER TYPES 
Many nuts closely resembling the I. X. L. are grown in California. None 
of the types are superior or equal to the I. X, L. 
39. JORDAN (MALAGUENA JORDAN) 
Origin—This type of Jordan almond is exported in large quantities from 
Spain. Great quantities of the kernels are imported into the United States, 
where they find a good market. Walter T. Swingle, Office of Foreign Seed and 
Plant Introduction, United States Department of Agriculture, secured scions 
of the Malaguena Jordan from Pedro Giraud in Spain, and propagation of 
the variety from these scions was begun at the United States Plant Introduction 
Garden at Chico, Calif., in 1912. Since that time trees of the Malaguena Jordan 
have been distributed to practically every almond-growing district in the 
country, but no large plantings have been made. 
Description 
TREE 
Very upright (ratio of width of head to height, 1:14). Not very dense. 
Trunk medium stocky; bark rough. 
Main branches.—Slightly crooked, long, upright, quite stocky. Branching 
angle acute. Wood medium tough, with many knots. Bark light reddish 
brown, rough on old branches; exfoliates in moderately thick flakes; striations 
common. 
Twigs.—Quite numerous and slender, giving the tree a willowy or feathery 
appearance. Branching angle sharply acute. Bark rather thin and tough, light 
green, commonly with brownish patches. 
_ Lenticels.—Very numerous, large (on bark 8 to 10 years old, ss by % to # by 
+ inch; on bark 5 to 6 years old, s» by 7s inch), long, narrow, with longitudinal 
cracks; raised, gray; shape usually long-elliptical, but variable: sides near 
middle tend to be straight in old lenticels; ends sharply acute or shortly 
acuminate. (See Pl. XVI.)
