生叶

Inflorescence a racemose panicle, initially terminal to leafy shoot; spikelets 3–7, 2.5–4.3 cm, rachilla internodes 3–4 mm, white-gray setose, apex densely white-gray ciliate; florets 3–7, terminal one sterile.

花序一种总状的圆锥花序，对叶状枝最初顶生；小穗3-7，2.5-4.3厘米，小穗轴节间3-4毫米，白色灰色具刚毛，浓密白色灰色具缘毛的先端；小花3-7，顶生的那个不育。

Perennial herbs; leaves alternate, elliptic or obovate-elliptic, apex obtuse or retuse; racemes 1.2-2 cm; petals free, apical appendages not stalked.

多年生草本叶互生，椭圆形或倒卵形椭圆形，先端钝的或微凹；总状花序1.2-2厘米；花瓣离生，顶端附属物而不是柄。

Long branch is rufous, show "" the glyph bends, smooth, have stipular thorn or not apparent; Short branch is born in the each other on the long branch of biennial above; Fall off sexual rod is finer, without bud, bunch is born on short branch, after autumn and foliaceous all fall.

长枝红褐色，呈&之&字形弯曲，光滑，有托叶刺或不明显；短枝在二年生以上的长枝上互生；脱落性小枝较纤细，无芽，簇生于短枝上，秋后与叶俱落。

The results show that the secretory ducts are schizogenous cavity which are only distributed in the stem and the leaf.The initial of the secretory duct drives from the ground meristem.

结果表明，分泌道为裂生腔隙，只分布于茎和叶中；分泌道原始细胞起源于基本分生组织；分泌道原始细胞团裂隙的扩大靠鞘细胞的插入和上皮细胞自身的切向伸长；成熟的分泌道呈圆形或椭圆形，由一层上皮细胞和其外的1 ～2 层鞘细胞包被。

Leaves in a rosette or opposite, often upper leaves alternate; petiole winged. Racemes secund; bracts small.

叶在一莲座丛或对生，通常上部叶片互生；叶柄具翅总状花序偏向；苞片小。

Leaves needlelike, slender or stout, straight or twisted, triangular, flabellate-triangular, or semiorbicular in cross section, stomatal lines several, on 1, 2, or all surfaces, vascular bundles 1 or 2, resin canals 2-10 or more, marginal or median, rarely internal, base enclosed by persistent or deciduous, membranous sheath. Pollen cones usually borne in spikelike clusters at base of 1st-year branchlets, sessile, cylindric or ovoid; pollen 2-saccate.

叶针状，纤细的或粗壮，直的或扭曲，三角形，扇形三角形，或半圆形在横断面上，气孔线数个，在1，2上，或全部表面，在第1 年的小枝，无梗，圆筒状的或卵球形的穗状的簇生在基部里的雄球花通常着生；花粉2囊。

Leaves opposite, semiterete and fleshy, subulate, scale-like, or obscure, bases united, apex obtuse or acute, sometimes with an acicular awn; leaf axil usually cottony.

叶对生，半圆柱形和肉质，钻形，鳞片状，或不明显，基部合生，先端钝或锐尖，有时具针状芒；通常的叶腋棉状毛。

Leaves usually few, along stem, opposite, seldom alternate, equal to subequal in a pair; leaf blade surfaces sericeous to hirsute or woolly, often glabrescent, base attenuate to rounded.

很少的叶通常，沿茎，对生，很少互生，成对的等长到近等长；在多毛或具绵毛，通常被绢毛的叶片表面，基部渐狭到圆形。

Herbs perennial, suberect, often clumped, with fleshy turions that leave brown leathery basal scales. Stems 7-25 cm tall, simple or sparsely branched, strigillose throughout, lacking raised decurrent lines.

多年生草本，近直立，叶棕色革质基生鳞片的通常丛生，具肉质具鳞根出条的。7-25厘米高的茎，单或疏生枝，全部具短糙伏毛，缺乏凸起下延线。

Leaves alternate, rarely whorled, sessile or subsessile, usually linear to linear-lanceolate.

叶互生，很少轮生，无柄或近无柄，通常线形到线状披针形。

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。
