1. It seems that cleistogamous flower may allow the plant to reproduce and assure some seed set even in conditions of unfavorable habitat.Chasmogamy sire outcrossing seeds to adaptive new habitats.

即使在不利生境中,闭锁花也能保障植物繁殖和一定的种子产生.而开放花则产生更多的异交种子以适应新的生境.

2. Cleistogamous plants produce flowers which either open only partly or not at all.

已知细胞质雄性不育植物有更高的产量；

3. Flowers zygomorphic, often reduced, cleistogamous, sometimes autogamous and intermediate.

开花左右对称，降低的通常，，有时自花受精和中间。

5. claws usually conspicuously exserted beyond calyx (but cleistogamous forms occur), oblanceolate, 8--10 mm, hairy at base;

瓣爪通常显著外露超过花萼(闭花受精形式发生)，倒披针形，8-10毫米，有毛的在基部；

6. pedicels of cleistogamous flowers produced from basal leaf axils much shorter than leaves, those on stolon much longer than leaves;

由基部叶腋生的闭花授精花的花梗远短于叶，由匍匐茎上的生的远长于叶；

7. Flowers bisexual, zygomorphic, solitary, often dimorphic (cleistogamous flowers later than chasmogamous ones);

花两性，左右对称，单生，通常二形(闭花授精花比开花受精的晚)；

花单生，腋生，多数沉水和。

9. Flowers open, cleistogamous, or sterile.

10. Petals usually longer than sepals (but sometimes smaller, cleistogamous flowers present), apex emarginate or shallowly bifid or toothed.

花瓣通常长比萼片(但是有时小，闭花受精花宿存)，先端微缺或浅2裂或齿。

11. Homogamy occurs in the closed cleistogamous flowers that appear late in the season in certain plants.
