Sessile spikelet narrowly lanceolate, ca. 4 mm, tinged reddish brown; lower glume subleathery in lower part, 2-keeled, papery and asperulous toward apex with obvious anastomosing veins, keels winged upward, apex bicuspidate; upper glume pilose on keel, apex acuminate or with 1–2 mm awnlet; awn of upper lemma 1–1.2 cm. Pedicelled spikelet resembling sessile, both glumes 1-keeled, cuspidate or mucronate.

狭披针形的无梗小穗，约4毫米，微染红棕色；更下部的颖片近革质在下部，龙骨状的2，纸质和向先端具明显网结脉，向上龙骨状具翅，先端；上面颖片关于龙骨状，先端渐尖具柔毛或具毫米awnlet；象无柄的上面外稃1-1.2 厘米Pedicelled小穗的芒，1 翻转的两颖片，骤尖或短尖。

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。
