Cultivar or taxon

 

Citrus x floridana (J.W. Ingram & H.E. Moore) Mabb. [=Citrus x aurantiifolia (Chrism.) Swingle X Citrus japonica Thunb.] (sensu Mabberley 2004); Citrus aurantiifolia (Christm.) Swingle X Fortunella sp. (sensu Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002)

Origin

 

Hodgson (1967) noted that:

"Eustis and Lakeland are sister hybrids of the West Indian lime and the round kumquat (Fortunella japonica), and Tavares is a similar hybrid with the oval kumquat (Fortunella margarita). They were made by W. T. Swingle of the U.S. Department of Agriculture in Florida in 1909 and were named and described in 1913."

Description

 

Crown compact or dense, not weeping. First-year twig surface glabrous; second- or third-year twig surface striate; thorns straight; prickles absent or not persistent. Petiole glabrous, length short; wings absent, if present, narrow or wide, adjoining the blade. Leaflets one, margin entire, crenate/crenulate, bluntly toothed or serrate/serrulate, shade leaflet blades flat or weakly conduplicate, sun leaflet blades weakly conduplicate or strongly conduplicate. Scent of crushed leaflets freshly lemon-like. Fruit as broad as long or longer than broad; rind medium green (4), light green with some break to yellow (5), green-yellow (6), yellow (7-10), or yellow-orange (11); rind texture smooth (1-3) or slightly rough (4-5); firmness leathery; navel absent; flesh yellow.

Swingle and Reece (1967) provided the following additional notes on the group:

"These hybrids have been described by Swingle (1914-1917, vol. 4, p. 1882, fig. 2176); by Swingle and Robinson (1923, pp. 235-38, pls. 4, 5); by Hume (1926, pp. 134-35, fig. 88); and by Hodgson (see [Hodgson 1967]).

Most of the named varieties of limequats, Eustis, Lakeland, etc., are hybrids of Fortunella japonica with Citrus aurantifolia 'Mexican,' the round kumquat being the pollen parent. Another named variety of limequat, the Tavares, has the oval kumquat as the pollen parent (Citrus aurantifolia 'Mexican' X Fortunella margarita)."

Hodgson (1967) provided the following additional notes on the group:

"Eustis and Lakeland are sister hybrids of the West Indian lime and the round kumquat (Fortunella japonica), and Tavares is a similar hybrid with the oval kumquat (Fortunella margarita). They were made by W. T. Swingle of the U.S. Department of Agriculture in Florida in 1909 and were named and described in 1913."

"Of the limequats, which are bigeneric hybrids, three varieties have been named (for description see Webber, 1943, pp. 667-68)—Eustis (fig. 4-90), Lakeland, and Tavares. Their importance is approximately in that order. All are characterized by fruits that closely resemble the West Indian lime in size, form, and composition and hence are reasonably acceptable substitutes. Eustis and Lakeland also closely approach the West Indian lime in color. Tavares, however, exhibits some of the orange coloration characteristic of the kumquat and the pink coloration of the flower buds which occurs in the West Indian lime. All of the limequats are more cold-resistant than the lime parent but considerably less so than the kumquat."

Notes

 

Hodgson (1967) additionally noted that: "None of the limequats has achieved commercial importance for the fruit, but Eustis and Lakeland are grown somewhat as ornamentals. In California, they are popular as potted or tubbed plants for patios and terraces."
