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

"Fruit small, round to oval; often necked; color deep reddish orange; sharply acid; nearly seedless. Tree moderately vigorous, upright, nearly thornless; leaves mainly unifoliolate.

This Oval kumquat and Rusk citrange hybrid first fruited at Sinton, Texas, and was named and described in 1923 (Swingle and Robinson, 1923, p. 235). It is an attractive ornamental and the fruit is beautifully colored but highly acid."
