Hsüopsida is parallel to the above three plant categories in Early Devonian and differs from them in that: the trimerophytes or Euphyllophytina have long fusiform sporangia terminating in trusses and P-type tracheids; the zosterophytes or Lycophytina are characterized by the exarch xylem; the rhyniophytes bear simple isotomous branches and S-type tracheids.

徐氏蕨类群与上述早泥盆世的三大类群并行，它不同于三枝蕨类或者是真叶植物的长纺锤形、成簇顶生的孢子囊和P-型管胞；不同于工蕨类或石松植物的外始式木质部；不同于莱尼蕨类植物简单的等二叉分枝和S-型管胞。

The plant with good growth is in big lotus below can wear unripe circuit small lotus, in addition annual spring the red that end still can take out similar bracketplant from phyllome bottom walks along a bine, front walking along a bine is long have lotus shape flocculus clump.

发育良好的植株在大莲座下面会着生一圈小莲座，此外每年的春末还会从叶丛下部抽出类似吊兰的红色走茎，走茎前端长有莲座状小叶丛。

Odd a shape compound leaf, flocculus 7-11(13), egg form or circle of regulations of state pouring egg, small change is simple, whole reason, opposite, grow 3.5-8.0cm, wide 2-5cm, tip acute is pointed, base ministry wide wedge or circle, without wool, below young leaf be grown closely fluff.

奇数羽状复叶，小叶7-11(13)，卵形或倒卵状矩圆形，薄革质，全缘，对生，长3.5-8.0cm，宽2-5cm，先端锐尖，基部宽楔形或圆形，无毛，幼叶下面密被长柔毛。

Xie Weiji counts a shape compound leaf, flocculus each other is unripe, 11-27 long elliptic or pod of form pouring egg is long and thin if point to shape, 3-12 part grows 2-3 in all centimeter, the section is broken easily, every contain condition of slightness of seed of * of a seed, kidney, black Brown.

有根瘤。叶为奇数羽状复叶，小叶互生，11-27枚长椭圆形或倒卵形荚果细长如指状，3-12节共长2-3厘米，节易断，每节含1粒种子*种子细长。肾状，黑褐色。

Flowers solitary, first leaves open, almost no flower stalk; sepals 5, flower buckle fold; petals 5, white or pink; stamen majority; carpels 1, there is a short pubescent.

花单生，先叶开放，几无花梗；萼片5，花扣反折；花瓣5，白色或粉红色；雄蕊多数；心皮1，有短柔毛。

Honeysuckle is half Changlu bush, bine half rampant, foliaceous egg circle, open the flower of horn form.

忍冬是半常绿灌木，茎半蔓生，叶卵圆形，开喇叭形的花朵。

According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder, is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.

根据多年的生产实践，从科学育苗、栽培管理、售前处理和病虫害防治等方面综合总结了叶子花的规模化矮化促成生产技术措施：选择泥炭土、蛭石和黄沙按3：2：1比例混合均匀的扦插基质，采用半木质化当年生枝条，剪成5~10cm长的2~3叶节一段，沾染1%自制生根粉的扦插育苗较组培育苗成本低，成活率高；结合修剪用2~5g/L的多效唑进行叶面喷洒能有效控制生长，矮化植株；选择2.5~4.0的丁酰肼叶面喷洒和每天保持不多于11h的短日照处理，能有效促进开花；销售前全株喷洒脱50mg/L NAA可延长花期20天左右；整个生产过程加强肥水管理、温湿度控制和环境清洁能有效防治病虫害发生。

Leaves opposite, shortly petiolate; leaf blade orbicular or ovate-cordate, 3--5-veined; stipules small, bristly, often fugacious.

叶对生，具短叶柄；心形叶片圆形或卵形，3-5脉；托叶小，刺人，经常先落。

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

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。
