cious variety. If fruits of some varieties are left on the trees too 

 long, the seed may sprout in the cavity as shown in the cross sec- 

 tion of this variety. (Photo by Division of Citriculture.) I. J. Condit.

Figure 26 — Harman (Natural size). This fruit is a Mexican type that 

 has shown a marked tendency to become disfigured by the cracking of 

 the skin, this seeming to be a varietal characteristic. It is also 

 rather prone to rot at the end. Seed large and loose in cavity. H. J.

Figures 27 a and 27 b — Fuerte (Natural size). A midwinter variety of good 

 quality, maturing normally between January 15 and April 1. Average 

 weight 10 to 14 ounces. Budded trees have fruited this winter in sev- 

 eral places. (Photo by Citrus Experiment Station.) H. J. Webber. 



Figure 28 — Bud variation in Fuerte avocado (One-half natural size.) 

 On right, normal Fuerte fruit; on left, round fruit of Redondo type 

 produced on the same budded tree of the Fuerte on the ranch of 

 Mr. J. T. Whedon, at Yiorba Linda, California. The tendency of this 

 variety to produce two types of fruit is said to be the cause for the 

 naming of two varieties, "Fuerte" and "Redondo," when they were 

 imported from Mexico. The Redondo is now known to be the round 

 fruited bud variation of the Fuerte. (Photo by Citrus Experiment

Figure 29 — Lyon (Natural size). This is one of the thick, hard-shelled 

 varieties that is attracting considerable comment. Season of ripening. 

 April to June. A prolific and precocious variety beginning to ripen 

 fruit two years from the bud. Tree a tall upright grower. (Photo by 

 Citrus Experiment Station.) H. J. Webber.
