description

The delicate-flowered gooseberry is an upright, dense and sparsely branched shrub with fine hairy and balding branches and one to three 2 to 19 millimeter long thorns at the nodes . The internodes are unproven, loose or densely covered with spines . The leaves have a hairy stalk 0.7 to 2 (rarely from 0.1 to 4) centimeters long. The leaf blade is simple, three- to five-lobed, rarely to seven-lobed, rounded or kidney-shaped-rounded, 0.5 to 1.5, rarely to 2.7 centimeters long, with a truncated or almost heart-shaped base. The lobes are elongated to wedge-shaped, sharply toothed, sometimes inflected with a rounded tip. Both leaf sides are glabrous or sometimes finely haired, rarely glandular hairy.

The flowers are white or light pink in color. They stand singly or in 1.5 to 2.5 cm long clusters of two to rarely four flowers with slightly downy hairy inflorescence axis. The bracts are lanceolate and 0.5 to 4 millimeters long. Two smaller bracts are formed per flower . The flower stalks are slightly hairy and 0.5 to 1 millimeter long. The flower cup is greenish white to white, rarely from 2.3, mostly 4 to 6 millimeters long, softly bristly on the outside and bare inside. The calyx lobes are horizontal, they are greenish white to white, lanceolate and rarely from 2.5, usually 3.5 to 7 millimeters long. The petals are erect, cream-colored with a red edge, white or pink, obverse lanceolate to spatulate-obovate, not clearly curved and 2 to 4.4 millimeters long. The stamens are almost as long as the petals; the stamens are straight, 1.3 to 3 millimeters long and glabrous; the anthers are cream-colored to purple, oval and 0.5 to 1.6 millimeters long. The ovary is softly hairy; the styles are 0.7 to 1 millimeter long, glabrous and almost fused to the scars . The fruits are edible, dark red to black, rounded with a diameter of 5 to 10 millimeters, glabrous, loosely hairy or hairy with glands. The delicate-flowered gooseberry flowers from April to June, rarely until July.

The number of chromosomes is 2n = 16.

Occurrence and location requirements

The natural range is in the US states Colorado , New Mexico , Texas , Arizona and Utah . The delicate-flowered gooseberry grows in coniferous forests at altitudes of 1700 to 3000 meters, on fresh, weakly acidic to weakly alkaline, sandy-loamy to loamy, nutrient-rich soils in light to partially shaded locations. The species loves warmth and is only moderately frost hardy .

Systematics

The Ribes Leptanthum ( Ribes leptanthum ) is a kind of the genus of currants ( Ribes ) in the family of gooseberry plants (Grossulariaceae). It is assigned in the subgenus Grossularia of the Grossularia section . The species was first scientifically described by Asa Gray in 1849 . The generic name Ribes is derived from the Arabic name of a type of rhubarb . The name was adopted for currants in the Middle Ages because of the sour taste of the berries of some species, which is reminiscent of the taste of rhubarb. The specific epithet leptanthum comes from the Greek and is derived from leptos for "thin" and anthos for "blossom" and thus refers to the delicate flowers.

use

The delicate flowering gooseberry is very rarely cultivated.
