Fruit red or reddish brown. Bark of the trunk separating into long thin persistent scales; fruit maturing in one season. Leaves closely appressed to the branchlet, obtusely pointed. Leaves conspicuously glandular-pitted, ternate or opposite; fruit red, subglobose, ¼′ in diameter. 2. J. Pinchotii (C, H). Leaves eglandular or slightly glandular; fruit reddish brown. Leaves ternate, rarely opposite; fruit short-oblong, ¼′—½′ in diameter. 3. J. californica (G). Leaves opposite, rarely ternate; fruit subglobose, ⅛′—¼′, in one form ¾′ in diameter. 4. J. utahensis (F, G). Leaves not closely appressed, spreading at the apex, long-pointed, glandular or eglandular; fruit subglobose, ⅓′—½′ in diameter. 5. J. flaccida (L). Bark of the trunk divided into thick nearly square plates; leaves eglandular or occasionally glandular-pitted; fruit subglobose to short-oblong, ½′ in diameter, ripening at the end of its second season. 6. J. pachyphlæa (H). Fruit blue or blue-black, with resinous juicy flesh, subglobose to short-oblong, 1/12′—⅓′ in diameter; seeds, 1—4; cotyledons 2. Leaves denticulately fringed, opposite or ternate; fruit maturing in one season.
