A series of crosses between the lime and the kumquats was made at Eustis, Florida, in June, 1909, in the Citrus grove of Mr, F.W. Savage. These crosses resulted in a number of hybrids varying in character, but all having fruits much like the lime in quality. This included the Eustis, Lakeland, and Tavares varieties. Eustis first fruited during the summer of 1918 in the greenhouse of the Department of Agriculture at Washington, D. C. The Eustis limequat fruit is of striking appearance, strongly resembling a West India lime in color, size, and texture. The color is a light yellow, resembling the color of grapefruit. When cut, the fruit shows its lime-like character. It is very juicy, thin-skinned, has few seeds, and the flavor can hardly be distinguished even by an expert from the true lime. Moreover, the rind is edible, like that of the kumquat so that the whole fruit may be utilized. It is particularly promising as a fruit for crystallizing. The spines on the bearing wood are very inconspicuous, a decided point in favor of this hybrid in contrast with the viciously spiny character of the common lime. Some of the other limequats exhibit rather long spines, even on the small twigs. Observations covering several seasons indicate that this limequat possesses much of the immunity to disease and insect pests enjoyed by the kumquat, The kumquat is the most resistant to Citrus-canker of all citrus varieties, a resistance amounting to practical immunity, an advantage the limequat has in some degree. Fruit oval (occasionally nearly spherical) slightly asymmetrical, mature fruits having a long diameter averaging 1 5/8 to 1 7/8 inches, diameter in cross section, 1 1/8 to 1 1/2 inches; calyx persistent; color light yellow (“picric yellow'*)”- rind thin 1/16 inch, very smooth and glossy, translucent; oil cells spherical, rather prominent having no bitter flavor; segments 6 to 9; seeds 5 to 12 , usually averaging 1 to the segment, small to medium size, 1/4 to 3/8 inch in length; pulp of light greenish color closely resembling lime, tender and juicy, flavor sharply acid (like the lime the fruit can be used when full sized but not fully colored); tree evergreen, vigorous, having a tendency to produce long shoots which bend downward with the weight of the fruit resemble the lime in producing a succession of crops, though not so markedly everbearing spines on bearing twigs very small, not injuring the fruit; flowers 5-petaled pure white (not streaked with pink as those of the lime and of most other limequats)’ leaves unifoliate, rather thick, dark green above, lighter below, tapering at both base and apex, 2 to 3 inches long, slightly folded along the midrib, having short, narrow petioles closely resembling leaves of the round kumquat except for larger size. The limequats are to all practical purposes hardy limes, but with the added advantage that the hybrid has proved immune to lime withertip, a specific lime disease caused by a parasitic fungus (Gloeosporium limetticolum Clausen) to which the pollen parent is immune.
