茎状的

Leaves basal and on stem, opposite, rarely in whorls of 3, lanceolate to ovate, pinnatifid to pinnatisect.

叶基生和在茎上，对生，很少3轮生，披针形的到卵形，对羽状全裂羽状半裂。

Petals yellow; flowers ca. 7 mm; middle outer sepal and apical appendage of keel pocketlike; stems without leaf scars and lenticels; leaf blade membranous, elliptic-lanceolate, ca.

花瓣黄色花约7毫米；中间外部萼片和龙骨瓣顶端附属物口袋状；没有叶痕和皮孔的茎；叶片膜质，椭圆状披针形，约3厘米宽，先端渐尖。

Male inflorescences spicate or scorpioid cymose; female inflorescences usually 2-8-flowered 1-flowered in S .

匍匐茎节不加厚；叶在上部的茎和分枝，肉质的，干燥时的厚纸质，椭圆状披针形， 1.5-4 * 0.5-1 厘米，侧脉4-6 每边。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有&盾状心皮&的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出&囊状心皮&的特点。

Plant stoloniferous, rhizomes absent; panicle contracted after anthesis.

有匍匐茎的植株，无的根状茎；圆锥花序收缩的在花后。

After histochemistry determination, it shows that dioscin take the form of liquid drop and exists mainly in the cells of parenchyma of ground tissue.

经组织化学测定，根状茎中薯蓣皂甙主要存在于基本组织的薄壁细胞中，呈液滴状。

Umbels compound, terminal on stem and branches; bracts absent; umbellules many-flowered, capitate; bracteoles several, lanceolate or ovate lanceolate, entire; pedicels obsolete.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
