圆筒形的

Inflorescence spikelike, cylindrical, composed of spiny or bristly deciduous burrs arranged along an angular, often sinuous rachis; burrs sessile or with an obconical basal stipe, each composed of 1 or more sessile spikelets surrounded by an involucre of spines and bristles; bristles flexuous or more often spinous,± flattened, grooved on the outer face, united below, the degree of union varying from a small basal disk to a deep cupule, inner spines or bristles often ciliate around spikelets. Spikelets lanceolate, acute; glumes unequal, shorter than spikelet, lower sometimes suppressed; lower floret membranous, staminate or neuter; upper floret firmer, protogynous.

花序穗状，圆筒状，由落叶的毛刺沿着一具角安排的具刺的或具刚毛，通常波状的轴组成；毛刺无梗或具基部的倒锥状柄，每一个由1无梗或更多组成以总苞的刺和刚毛包围；或更多的刚毛曲折通常spinous，多少扁平，在外面上具凹槽，下面的合生，协会的度从一小的基部的花盘变化到一深的壳斗，小穗披针形，锐尖；不等长的颖片，短于小穗，降低有时压抑；更低的小花膜质，雄蕊花的或中性；坚定的上面小花，雌蕊先熟。

Inflorescence of paired racemes, or occasionally subdigitate, terminal and axillary, exserted or sometimes supported by a spatheole; racemes 1-sided, when paired often locked back to back and appearing as a single cylindrical raceme, spikelets of a pair similar or not; rachis internodes and pedicels stoutly linear to thickly clavate, U-shaped or triquetrous in cross section.

配对的总状花序，或偶有subdigitate，顶生和腋生的花序，有时被spatheole 支持的外露的或； 1边的总状花序，被配对背靠背锁住的通常并且出现不作为单个圆筒状总状花序，相似的对与否；节间的轴和对厚厚棍棒状，U形或者三棱的在横断面上略胖线的花梗。

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。
