小梗

Sessile spikelet narrowly lanceolate, ca. 4 mm, tinged reddish brown; lower glume subleathery in lower part, 2-keeled, papery and asperulous toward apex with obvious anastomosing veins, keels winged upward, apex bicuspidate; upper glume pilose on keel, apex acuminate or with 1–2 mm awnlet; awn of upper lemma 1–1.2 cm. Pedicelled spikelet resembling sessile, both glumes 1-keeled, cuspidate or mucronate.

狭披针形的无梗小穗，约4毫米，微染红棕色；更下部的颖片近革质在下部，龙骨状的2，纸质和向先端具明显网结脉，向上龙骨状具翅，先端；上面颖片关于龙骨状，先端渐尖具柔毛或具毫米awnlet；象无柄的上面外稃1-1.2 厘米Pedicelled小穗的芒，1 翻转的两颖片，骤尖或短尖。

Inflorescences axillary; spikes terminal and axillary or only terminal, densely arranged into 4--11 spikelets; lateral spikes almost sessile; bracts longer than first bractlet, margin broadly membranous and wider than herbaceous part, apex rigidly and thickly cuspidate; each flower subtended by a bractlet; first bractlet similar to bracts but slightly shorter.

花序腋生只顶生的穗状花序顶生和腋生或，浓密排列为4-11小穗；侧的穗状花序几无梗；苞片长于第一个小苞片，边缘宽膜质和宽比草质深裂，刚硬和厚骤尖的先端；每花以一小苞片被包着；首先除了稍短小苞片类似苞片。

Inflorescence terminal, usually of digitate, subdigitate, or corymbiform racemes, infrequently paniculate; racemes shortly pedunculate, composed of several spikelet pairs (if paniculate, more than 8 spikelet pairs present), basal homogamous spikelet pairs absent; rachis internodes and pedicels slender with a median translucent stripe between thickened margins.

通常是指状，subdigitate，或伞房花序状的总状花序的花序顶生，很少发生圆锥状；总状花序有短花序梗，由组成数个对(如果圆锥状，超过对宿存8小穗)，无的基部同性花小穗对；节间的轴和有在加厚的边之间的一个中间的半透明的条纹的花梗纤细。

Pedicelled spikelet larger than sessile, resembling homogamous spikelets, awnless; callus slender, pedicel-like; true pedicel reduced to a stump.

Pedicelled比无梗大的小穗，象同性花的小穗，awnless；胼胝体纤细，象花梗一样；真实的花梗退化至一根残干。

Sessile spikelet lanceolate, 4–5 × 1.2–1.4 mm; lower glume leathery with expanded rounded flanks below middle, herbaceous, strongly veined and sharply 2-keeled above, glabrous or villous, keels usually winged, apex 2-toothed; upper glume attenuate into mucro or awnlet to 2 mm; awn of upper lemma 1.2–1.5 cm. Pedicelled spikelet laterally compressed, similar to sessile, upper lemma awned.

无梗小穗披针形， 4-5 * 1.2-1.4 毫米；下部颖片革质具膨大圆形侧面中间以下，草质，龙骨状的脉粗壮和锐的2在上面，上面颖片渐狭窄成为短尖头或awnlet到2毫米；上面外稃的芒类似于无柄，上面的外稃具芒的1.2-1.5 厘米Pedicelled小穗侧面压扁。

Wings of nutlet ca. 1/2 as wide as nutlet or more; female inflorescence pedunculate.

约的小坚果的翅的宽是小坚果或更多的宽的1/2；雌花序有花序梗。

Leaves suborbicular; peduncle 3-4 mm; wings of nutlet ca. as wide as or slightly narrower than nutlet

叶近圆形；花序梗3-4毫米；小坚果的翅约和或比小坚果稍狭窄一样宽 31 Betula rotundifolia 圆叶桦

Sessile spikelet broadly oblong or obovate, 8–10 × 2.5–3.5 mm; lower glume leathery toward base, flanks rounded in lower 1/3, villous with stiff ca. 3 mm hairs, papyraceous and puberulous above, keeled and winged above middle, wings ca. 0.8 mm wide with ciliolate margin, apex truncate-denticulate; upper glume keeled and winged above middle, villous on midline below wing; awn of upper lemma weakly geniculate, up to 1.5 cm. Pedicelled spikelet laterally compressed, otherwise resembling sessile, awnless.

无梗小穗宽长圆形或倒卵形， 8-10 * 2.5-3.5 毫米；对于基部革质的更低的颖片，从侧面包围圆形的在下部1/3，具长柔毛具硬的约3毫米毛，在上面纸质和被微柔毛，上面颖片龙骨状和具翅的在中部以上，在低于翅的midline上的具长柔毛；身体虚弱膝曲的上面外稃的芒，可达1.5 厘米Pedicelled小穗侧面压扁，否则象无柄，awnless。

Even adjacent spikelets may differ in this character, which is not related to whether the spikelet is sessile or pedicelled.

即使临近小穗5月在这特征方面不同，与没有关系是那些小穗在无梗或的。

The strongly bilateral racemes have all the sessile spikelets on one side and all the pedicelled spikelets on the other.

强烈两侧总状花序有的全部无梗小穗在一侧和的全部pedicelled小穗在另一个上。

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
