花枝多丛生，花单生枝顶，基部包围在上部叶丛中，无花梗；花萼筒带紫色，倒锥形，长10~12mm ，裂片与上部叶同形；花冠长钟形，长5~6cm ，径约2.5cm ，裂片卵圆形，褶整齐或微偏斜，边缘啮蚀状；雄蕊着生于冠筒下部，整齐，花丝蓝色，钻形，基部联合包围子房，花药黄色，狭矩圆形，花柱线形，柱头2裂，裂片反卷，线形。

Leaves alternate, stipulate, petiolate; leaf blade usually palmately veined, entire or various lobed.

叶互生，具托叶，具叶柄；叶通常为掌状脉，全缘或者各种各样的裂。

Leaves all alternate, simple, palmatilobate.

所有叶互生，为单叶，掌状浅裂。

Leaves alternate; petiole usually long, apex or base of leaf blade 2-glandular; leaf blade simple, penninerved.

叶互生 ；通常的叶柄长，叶片的先端或基部2腺；叶片单叶，羽状脉。

Leaves alternate, shortly petiolate, simple, penninerved.

托叶小。叶互生，短，具叶柄，单叶，羽状脉。

The flower has calorie of power, sepal egg shape wraps around needle form, petaline corydalis is lubricious, have canaliculus state, straight or go up a bit curved; Florescence 4 ～ May, purple floret, xie Rengqing of after autumn bine is green be like first, the companion other the flower has acicular small fruit, till at the beginning of the winter, ground upside divides ability wither, because this is wonderful ground by the plant, but sheet is planted the predestined relationship issues a Zhi Yulin or on the meadow of exposed to the sun, also but with other herb, wait like bison grass, dandelion mix kind, form level ground of beautiful compose flowers and plants.

紫花地丁叶基生，狭披针形或卵状披针形，边缘具圆齿，叶柄具狭翅，托叶钻状三角形，有睫毛。花有卡柄，萼片卵状披针形，花瓣紫堇色，具细管状，直或稍上弯；花期4～5月，紫色小花，秋后茎叶仍青绿如初，花旁伴有针状小果，直至冬初，地上部分才枯萎，因此是极好的地被植物，可单种成片植于林缘下或向阳的草地上，也可与其他草本植物，如野牛草。蒲公英等混种，形成漂亮的缀花草坪。

Changes of leaf pigment content,soluble sugar content,enzyme activity and photosynthesis characters in leaf of Photinia×frasery"Red Robin"were searched of five different shading treatments(100%,80%,50%,25%,10%transmission rate).The seasonal variation of leaf color and stability of anthocyanin were studied in this paper.Purpose of the research is to master the Physiological characters during leaf color transformation of Photinia×frasery"Red Robin",and provide evidences to promote introduction cultivation and the application under different garden environment of them.

本文以2年生红叶石楠(Photinia×frasery'RedRobin)扦插苗为试材，探讨了不同遮光处理透光率分别为100%(全光照、80%、50%、25%、10%条件下叶片色素含量、可溶性糖含量、苯丙氨酸解氨酶活性、抗氧化酶活性变化及光合作用日变化，同时对其叶色的季节变化及花色素苷的稳定性进行了初步探讨，以掌握红叶石楠叶色变化的生理特征，为红叶石楠的广泛引种栽培及在不同园林环境中的应用提供科学依据。

Leaves alternate, simple, pinnately veined, entire to irregularly serrate or lobed, rarely pinnatifid; stipules absent or rarely present.

叶互生，单叶，羽状脉，全缘、有不规则的有锯齿或者浅浅裂，很少羽状分裂；存在的无托叶或很少。

Inflorescence borne in axil of leaf or scalelike bract, a solitary, many-flowered umbel; peduncle usually compressed, without a scalelike prophyll at base.

叶或的花序生于腋鳞片状的苞片，一单生，多花的的伞形花序；花序梗通常压缩，没有一鳞片状的先出叶在基部。

Leaves toward base of stem: petiole ca. 0.8-1.3 cm, tomentose, prophyll up to 1/2 as long as petiole; leaf blade ovate or narrowly ovate, 10-18 × 5-10 cm, papery, glabrous to abaxially tomentose, adaxially pilose along veins, base cordate, oblique, apex acute or acute-acuminate; veins 9, apical pair arising 1-3 cm above base, others basal; reticulate veins conspicuous.

约的对于scircapetiole的基部的叶0.8-1.3厘米，被绒毛，先出叶可达1/2的倍于叶柄；叶片卵形或狭卵形， 10-18 * 5-10 厘米，纸质，无毛到背面的被绒毛，正面具柔毛的沿脉，基部心形，偏斜，先端锐尖的或锐尖尖；脉9，出现的顶端的对超过基部1-3厘米，其它人基部；网脉明显穗状花序对生。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
