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。

Inflorescence a raceme or compact thyrse, pendent, usually open before leaves appear; peduncle with 2 or 3 basal leaves; each flower usually with 1 bract and 2 bracteoles.

花序为一总状花序或小型聚伞圆锥花序，下垂，通常开阔的在叶出现之前；花序梗具2或3基生叶；每花通常具1苞片和2小苞片。

Experiments show that: The small Ficus wasps dig both biting bud bud bracts port channel port can also dig in the fruit wall channel of non-bud mouth.

实验表明：大叶榕的小蜂既能撕咬苞口苞片开掘苞口通道，也能在果壁上开掘非苞口通道。

Leaves simple, usually alternate, rarely opposite or verticillate, sometimes crowded at apices of branches; stipules usually small and caducous, sometimes larger, leaflike and persistent, rarely absent; petiole generally present, sometimes with apex 2-glandular and/or with additional glands along petiole length; leaf blade usually pinnate-veined, sometimes 3-5-veined from base or palmate-veined, with or without pellucid dots or lines, sometimes with a pair of glands at junction of blade and petiole, margin entire or toothed, teeth glandular or not. Inflorescences axillary, terminal, or cauliflorous, of various forms: racemose, spicate, cymose, corymbose, or paniculate, sometimes flowers fasciculate, or solitary; pedicels often articulate; bracts and bracteoles usually small to minute.

单叶，通常互生，很少对生或轮生，有时在枝端簇生；托叶通常小并且早落，有时大，叶状并且宿存，很少无；叶柄通常存在，有时先端有2个腺体，或沿着叶柄有腺体；叶片通常羽状脉，有时基部3-5出脉或掌状脉，有或无透明小圆点或线，花序腋生，顶生，或者茎生，或多种形式：总状，穗状，聚伞状，伞房状，或者圆锥状，有时花束状，或者单生；花梗通常有节；苞片和小苞片通常小到微小。

Lateral branches penetrating leaf sheaths. Leaves alternate. Inflorescences borne at each node, opposite leaves, emerging from mouth of leaf sheath, each a large panicle of numerous cincinni; cincinni each subtended by an involucral bract; bracts similar to leaves, becoming smaller toward apex of cincinnus.

叶互生 花序着生在每节，与叶对生，从叶鞘口那里出现，每一个为一大的多数蝎尾状聚伞花序的圆锥花序；蝎尾状聚伞花序各自以一总苞片被包着；类似于叶的苞片，向蝎尾状聚伞花序先端变小。

Basal leaves rosulate; leaves, involucral bracts, and bracts usually densely arachnoid; roots 1--1.5 mm in diam.

基生叶莲座状；叶，总苞片，和苞片通常浓密；根1 --1.5毫米直径 2 CYANOTIS arachnoidea 蛛丝毛蓝耳草

Flowers unisexual and plants dioecious; inflorescences without leaflike bracts or with few caducous leaflike bractlets; seeds abaxially longitudinally furrowed for 3/5 length

单性的花和植株雌雄异株；花序没有叶状苞片或具很少早落的叶状的小苞片； 3/5的期间的种子背面的纵沟 11
