无萼的

The lack in Galitzkya of simple and forked trichomes and staminal appendages, and the development of thick, branched caudices and saccate, lateral sepals clearly distinguish it from Berteroa .

在单和分叉的毛状体和雄蕊的附属物的Galitzkya里的缺乏，后面属有单和分叉的毛状体，雄蕊的附属物和无气囊的萼片。

Scapose perennials with caudices covered with petioles of previous years; trichomes almost exclusively simple, restricted to leaf margins and sepals abaxially; stems leafless or with 1-3 leafy bracts

"扎矮76"的形态解剖特征与普通山定子和杂交后代中普通型植株对比，"扎矮76"和其它携带Dw主基因植株的：春梢短59.6-66.2％，梢长与梢粗比值小33.2-58.4％，节间短14.0-42.7％，春梢节数少40.7％，杂种苗下胚轴短65.0％，春梢叶柄形指数小34.5-50.2％，叶柄短25.2-45.7％，春秋梢交界处有瘤状突起，叶缘波状，萼片肥厚有刺状突起，萼部缢痕不明显，脱萼后萼痕较大、萼洼平或高于果面；新梢生长点宽而短，在距顶端1.0gmm处有较多体积较大、内容物较少、细胞核小或无的待化细胞。

Sepals 6.6-7.8 mm, mucro 1.6-2.5 mm, ratio of mucro/sepal length = 0.22-0.37, outside with 0.1-1.2 mm antrorse to patent nonglandular trichomes, inside glabrous.

萼片6.6-7.8毫米，短尖头1.6-2.5毫米，短尖头/萼片长度比率=0.22-0.37，外面具0.1-1.2毫米向前到开展的非腺毛，里面无毛。

Sepals imbricate or valvate, rarely spathaceous, mostly (2 or)3-6, rarely more, usually free or connate at base only, sometimes partly united into a tube, caducous or persistent, rarely accrescent. Petals 3-8, rarely more, often isomerous and alternating with sepals, free, imbricate or valvate, rarely contorted, similar to sepals or not, sometimes with a fleshy adaxial basal scale, or petals absent. Disk present, entire, lobed, or comprised of free or connate disk glands, these extrastaminal, interstaminal, or intrastaminal, or extragynoecial, or disk absent.

萼片覆瓦状或镊合状排列，很少佛焰苞，几乎(2或者)3-6，很少更多，通常离生或者只是基部合生，花瓣3-8，很少更多，通常与萼片同质并且互生，分离，覆瓦状或镊合状排列，很少旋转状，与萼片相似或不相似，有时在近轴基部有一个肉质的鳞片，或花瓣无。

Petals alternisepalous,(2-)4, absent in female flowers of some Myriophyllum , imbricate, longer than sepals, often deciduous with stamens.

花瓣与萼片互生，(2-)4，但是Myriophyllum的一些种类雌花无花瓣，花瓣覆瓦状排列，比萼片长，通常与雄蕊一起脱落。

Stamens 1 or 2 × as many as sepals; filaments short, slender; anthers basifixed, mostly oblong or linear, 4-loculed, dehiscing by slits, antisepalous anthers sometimes somewhat longer than antipetalous ones; pollen grains shedding at 3-celled stage. Ovary inferior, 1(or 2)- or 4-celled, septa solid or practically absent (present only at base and apex of ovary); styles as many as sepals, alternisepalous, free, mostly short, grading into globose or subulate stigmas, spreading in fruit; stigmatic papillae hairlike; ovules as many as styles, rarely 1, apical, pendulous, anatropous.

雄蕊1或2 *同数萼片；花丝短，纤细；花药基着，通常长圆形或者线形，4室，纵向开裂，对萼花药稍比对瓣花药长；花粉粒在3室的阶段散落子房下位，1(或者2)或4室，隔膜实心或几乎无(只在基部和子房先端存在)；花柱和萼片同数，与萼片互生，离生，柱头乳突毛发状；胚珠与花柱同数，很少1，顶生，倒生。

Sepals and petals 5, persistent after anthesis, sepals free, entire or rarely glandular-ciliate, petals entire or glandular-ciliate, apiculus absent.

萼片和花瓣5，宿存在花后，萼片离生，全缘或很少具腺具缘毛的，花瓣全缘或具腺具缘毛，细尖无。

Male flowers: sepals mostly 5, imbricate to valvate, free; petals 5, smaller or nearly equal to sepals; disk glandular, usually 5, and opposite sepals; stamens 10-20; filaments free, inflexed in bud; anthers muticous; pistillode absent.

雄花： 多数的萼片5，覆瓦状到镊合状，离生；花瓣5，小或近等长于萼片；花盘具腺，通常5，与萼片对生；雄蕊10-20；花丝离生，在芽中内折；花药钝；无退化雌蕊。

Calyciflorus clones were cultured at 15℃, 20℃, 25℃and 30℃with 3.0×106 cells/mL of Scenedesmus obliquus to investigate their differences in life history characteristics and their responses to increasing temperature.

结果表明，温度对萼花臂尾轮虫存活率和繁殖率的影响在不同克隆间存在着差异。20℃和25℃下，四个克隆轮虫的世代时间和净生殖率均分别无显著的差异；20℃、25℃和30℃下，四个克隆轮虫的平均寿命和出生时的生命期望亦然。

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

这两个团体间的分歧难以掩饰。

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。
