The plant pink lucieae , also Rosa Wichuraiana , Wichura Rose or Rose Memorial, belongs to the genus of roses ( Rosa ) within the family of the rose family (Rosaceae).
description
Appearance and leaf
Depending on the location, Rosa lucieae grows as a deciduous to semi- evergreen shrub . The long, prostrate, spreading or climbing shoot axes are more than 1, usually 3 to 5 meters long. Roots sometimes form at the nodes of the shoot axes. The stem-round stem axes have a red-brown bark , which is initially downy and hairy and soon becomes bald. The shoot axes are spiked with spines , sometimes in pairs. The curved or almost straight spines are often tinged purple and 4 to 5 millimeters long and about 2 millimeters wide, flat and gradually widening to a broad base.
The alternately arranged leaves are divided into petioles and leaf blades and a total of 5 to 10 centimeters long. The petiole and the rhachis leaf are sparsely spiky and sparsely hairy glandular and downy. The imparipinnate leaf blade usually contains five or seven, rarely nine pinnate leaves. The leathery leaflets are 1 to 3 centimeters long and 0.7 to 1.5 centimeters wide, elliptical, ovoid or obovate with an almost rounded or broadly wedge-shaped base and a long, rounded, blunt or pointed upper end. The leaf margins are sawn away. Both leaf surfaces are bare. The underside of the leaf is greenish and the upper side is dark green. There is a raised median nerve on the underside of the leaflets. The 5 to 9 millimeter long stalked terminal leaflet is 15 to 30 millimeters long and 12 to 20 millimeters wide and ovoid to obovate. The stipules are 10 to 12 millimeters long and 2 to 3 millimeters wide and are fused with the petiole for most of their length. The free area of the stipules is lanceolate with a short, pointed upper end, a glandular serrate or serrated edge and sparsely hairy glandular-downy hair. The 2 to 4 millimeters long, bald ears are erect with a frayed edge.
Inflorescence, flower and fruit
The flowers stand together individually or in groups of five to over 20 in umbrella-like inflorescences that have a diameter of 1.5 to 3 centimeters. The 0.6 to 2.5 cm long peduncle is initially sparsely hairy and soon bald and rarely sparsely hairy glandular and downy. The one to three early sloping, bald bracts are lanceolate with a length of 9 to 16 millimeters and a width of 2.5 to 5 millimeters.
The hermaphroditic flowers , which smell of apple or clover, have a diameter of 2 to 2.5 centimeters and are radially symmetrical and five-fold with a double flower envelope . The hemispherical or bottle-shaped flower cup (hypanthium), with a length of 4 to 6.5 millimeters and a width of 2 to 3 millimeters, has sparsely glandular and downy hair. The five relatively late falling sepals are 6 to 8 millimeters long and 1 to 1.5 millimeters wide and lanceolate or ovate-lanceolate with a pointed upper end and the edge is smooth to pinnate. The underside of the sepals is almost bare and the top is hairy densely downy. The five free white or bald, outside bare petals are obovate with a length of 13 to 15 millimeters and a width of 11 to 15 millimeters with a wedge-shaped base and rounded, blunt upper end. Sometimes there are two rows of petals. There are many stamens present. There are many (12 to 21) free carpels . The downy, hairy styles are fused into a column, are a little longer than the stamens and protrude above the corolla. The disc has a diameter of 3 to 4 millimeters.
In China, the flowering period extends from April to July and the rose hips ripen from October to November.
The rose hip, which is purple-black-brown or red when ripe, is 5 to 10 millimeters long and 6 to 18 millimeters in diameter ± spherical, prickly and sparsely hairy with glandular and downy hair. The one to eleven achenes are dark tan and 4 to 4.5 millimeters long and 2 to 2.5 millimeters wide.
Chromosome set
The number of chromosomes is 2n = 14, rarely 28.
Locations in culture
It is evergreen in mild locations and forms up to 5 meters long - often prostrate - trunks with greenish bark. The Wichura rose can be cultivated in most types of soil , but thrives best on heavy, non-damming soils and in sunny locations.
Systematics and distribution
It was first described in 1871 under the name ( Basionym ) Rosa lucieae by Adrien René Franchet and Alphonse Trémeau de Rochbrune in François Crépin : Bulletin de la Société Botanique de Belgique , Volume 10, Page 324; there "Luciae" written. The specific epithet lucieae honors Madame Lucie Savatier . In 1886 Rosa wichuraiana was first described by the Belgian botanist François Crépin in Bulletin de la Société Botanique de Belgique , Volume 25, 2, pages 189-192; it is now a synonym for Rosa lucieae var. lucieae . The specific epithet wichuraiana honors the German official Max Ernst Wichura , who collected this type of rose in 1859 during a diplomatic mission in Japan for the Botanical Garden in Berlin. More synonyms for Rosa lucieae Franch. & Rochebr. ex Crép. are: Rosa philippinensis Merr. , Rosa wichuraiana Crép. , Rosa Wichuraiana var. Poteriifolia Koidz.
Rosa lucieae belongs to the section Synstylae from the subgenus Rosa in the genus Rosa .
Rosa lucieae is common in Korea , the Philippines , Japanese islands, Taiwan, and the Chinese provinces of Fujian , Guangdong , Guangxi, and Zhejiang . For example, it is a neophyte from North America to Mexico and on the Pacific Islands .
From Rosa Lucieae Franch. & Rochebr. ex Crép. there are the varieties:
- Rosa lucieae var. Fujisanensis Makino (Syn .: Rosa fujisanensis (Makino) Makino ): It occurs only on the Japanese islands of western Honshu and Shikoku .
- Rosa Lucieae Franch. & Rochebr. ex Crép. var. lucieae (Syn .: Rosa acicularis var. taquetii (H.Lév.) Nakai , Rosa lucieae var. wichurana (Crép.) Koidz. , Rosa taquetii H.Lév. , Rosa wichurana Crép. ): It is in Korea , common in the Philippines , the Ryūkyū Islands , Taiwan and the Chinese provinces of Fujian , Guangdong , Guangxi and Zhejiang .
- Pink lucieae var. Onoei (Makino) Momiy. ex Ohwi (Syn .: Rosa onoei Makino ): It occurs only on the Japanese islands of central to western Honshu, Kyushu and Shikoku.
- Pink luciae var. Rosea H.L.Li : It is known only from the type of facility in Taiwan.
breeding
The genome of the synonyms Rosa wichuraiana can be found in a great many Rambler roses . Their up to 6 meter long stem axes are very flexible and therefore hang over heavily if they are not supported. The leathery leaves of the Wichura rose are healthy, 5 to 10 cm long, with a glossy top. From July to August, its apple-scented blossoms appear in small, cone-shaped, white panicles. It gets egg-shaped, deep red rose hips, which contrast nicely with the foliage.
There is a particularly showy sport , Rosa wichuraiana 'Variegata', with variegated white foliage. The varieties bred from Rosa wichuraiana bloom once, but very richly and for a long time. An exception is the 'New Dawn' variety , which has the ability to be remounted .
