The trees of the Dense-Unproductive^ strain are the least productive of any of those of the Eureka variety under observation in the per- formance-record plats, and the light yield of these trees is coordinated with a correspondingly inferior quality of the fruits. In many ways they resemble the trees of the Shade-Tree strain. The crops of fruit are borne at about the same season, but the habit of growth of the trees, instead of being spreading, is more erect and dense, as shown in figure Fig. 6.—a typical lemon tree of the Dense-Unproductive strain of the Eureka variety, 10 years planted The vigorous and dense vegetative characteristics and lack of fruit are very marked. The trees usually have a large amount of vigorous vegetative growth, or suckers. The leaves are usually not as large as those of the Shade-Tree strain, but in general their shape and color are very similar. The number of leaves produced by the trees of this strain is greater than is the case with the trees of the Shade-Tree strain. The percentage of imperfect flowers of the trees of this strain is larger than in those of the Shade-Tree strain. This abnormal condition of the "blossoms is partly responsible for the light yield of fruits of the trees of this strain. The pistils are often small, rudimentary, or.
