Jason,
Ischia /White Ischia/ Singleton/ Brocket Hall is a different cultivar. Hope this helps. Here is what Condit and others say:
"Although trees were grown at the early California Experiment Stations, the varietyfailed to receive favorable attention on account of the small size of the fruit. In good weather the figs dry partly on the tree and drop with little spoilage; they are also good or homemade preserves and pickles.The tree has a dense habit of growth, with numerous small, short twigs; terminal buds are olive green in color. Leaves small, glossy above, mostly 3-lobed; upper sinuses shallow and narrow; base truncate, sometimes decurrent; margins crenate (plate 13). Description of figs is from specimens grown at Riverside.
Breba crop small or none; fruits below medium, spherical, with very short neck; stalk short and thick; eye rather large, open; color of skin green, tinged with violet; pulp light strawberry; quality poor.
Figs of second crop borne profusely; size small, averaging 18 grams in weight, up to 1-1/2 inches in diameter by 1-1/4 inches from base to apex; shape oblate to spherical, with or without short neck; stalk short and thick, or up to 1/2 inch long, sometimes swollen toward the apex; ribs narrow, prominent; eye medium, open, scales pink; surface dull, with faint bloom; white flecks scattered and inconspicuous, as shown by Condit (1941a, fig. 9, H); skin checking crisscross, discolored or blemished by circular brown spots at complete maturity; color green, flushed with violet; meat white, thin; pulp very light strawberry; flavor sweet; quality fair. (Plates 9; 15, D.)
Caprified specimens slightly larger and heavier; pulp deep strawberry; flavor somewhat acid."
