Origin

 

The Chiefland Budwood Facility (2010) provided the following notes under Verna (clone DPI-203-9): "Entered by Jamal Uddin in 2008. Restricted"

Description

 

Crown compact or dense, not weeping. First-year twig surface glabrous; second- or third-year twig striate; thorns straight; prickles absent or not persistent. Petiole glabrous, length short, wings absent. Leaflets one, margin bluntly toothed, shade leaflet blades weakly conduplicate, sun leaflet blades weakly conduplicate. Scent of crushed leaflets freshly lemon-like. Fruit as broad as long or longer than broad; rind yellow-orange (11), orange (12), or red-orange (13); rind texture slightly rough (4-5); firmness leathery; navel absent; flesh yellow; taste sour.

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

"Fruit medium in size, oval to broad-elliptical; neck or collar short; nipple well developed. Seed content variable, but usually few to none. Color bright yellow at maturity. Rind medium-thick (thinner in summer crop); surface somewhat pebbled, rough; tightly adherent. Crop comes mainly in winter but holds well into summer, with undesirably large fruit, however.

Tree very vigorous, upright-spreading, large, and productive."
