具波齿的

Culm sheaths tardily deciduous, with several marginal white stripes on each side, leathery, glabrous, apex obliquely truncate with unequal, triangular protuberance on each shoulder; auricles unequal, linear-lanceolate, small, usually wrinkled, abaxially hispidulous; oral setae well developed, 5–10 mm, undulate, hispidulous at base; ligule 5–7 mm, margin irregular, dentate, laciniate; blade erect, broadly lanceolate, abaxially glabrous, base nearly 1/2 width of sheath apex.

缓慢的竿箨脱落，叶耳不等长，线状披针形，小，通常起皱，背面；口头的刚毛发育良好，5-10毫米，波状，具短硬毛在基部；叶舌5-7毫米，边不规则，有齿，有穗；叶片直立，宽披针形，背面无毛，鞘先端的1/2 宽度的近基部。

The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.

例如，荫湿生环境下的羽枝青藓Brachythecium plumosum，其中肋细胞胞壁较薄，无导水主细胞和副细胞的分化，也没有厚壁细胞分化，能够在阴湿环境下吸收水分和养分；钝叶匍灯藓Plagiomnium rostratum具有与旱生藓类植物相似的中肋结构，叶片较厚，中肋具导水主细胞，中肋背面具厚壁细胞，这些特点使该种藓类植物能够分布于间隙性干旱胁迫的环境中；水灰藓Hygrohypnum luridum叶片纤细柔弱，仅1层细胞，细胞胞壁薄，叶表无附属结构，中肋细胞层数少，无导水主细胞分化，也没有厚壁细胞，这些特点使得水灰藓'能够生长在水生环境中；东亚小金发藓Pogonatum inflerum和波叶仙鹤藓Atrichum undulatum的叶腹面覆盖着栉片，东亚砂藓Racomitrium japonicum、大羽藓Thuidium cymbifolium、福氏蓑藓Macromitrium ferriei、东亚短颈藓Diphyscium fuhifolium、扭口藓Barbula unguiculata和角齿藓Ceratodon purpureus的叶片表面有乳头状突起或疣状物，这些附属结构使它们能够适应于旱生的环境中。

Cauline leaves shortly petiolate or sessile, not auriculate, entire, dentate, or serrate.

或者无柄的茎生叶具短叶柄，并非耳形，整个，有齿，或者使成锯齿波。

In contrast, P. obliquum has lamina with basal pinnae contracted, scales of petiole brown adaxially, scales of rachis up to 2.3×0.5 mm, pinnae green, chartaceous, matt adaxially, and serrulate on margin, and microscales 0.2-0.5×0.1-0.2 mm.

obliquum相似，但吞天井耳蕨的叶片基部最宽，向基部不缩短，叶柄鳞片近轴面深棕色，叶轴鳞片达3.6×0.8mm，羽片深绿色，近革质，向轴面有光泽，边缘具略波状微齿或近全缘，小鳞片达2×0.5mm；而斜羽耳蕨的叶片的基部缩短，叶柄鳞片向轴面棕色，叶轴鳞片达2.3×0.5mm，羽片绿色，草质，向轴面无光泽，边缘有锯齿，小鳞片达0.5-0.8×0.2-0.3mm。

Leaves alternate, spiral, petiolate; stipules deciduous, intrapetiolar, completely connate, leathery, often large, apex entire; leaf blade leathery or papery, pinnately veined, rarely 3-5-veined, margin entire, undulate, or crenulate; cystoliths punctiform.

叶互生，螺旋形，具叶柄；落叶的托叶，叶柄内，完全合生，似皮革，经常大，先端全缘；叶片革质或纸质，成羽状脉，很少3-5脉，边缘全缘，波状，或具细圆齿；钟乳体点状。

Leaf blade drying papery, glabrous, except veins abaxially sparsely puberulent, margin entire to indistinctly denticulate or repand; peduncle 6-16 cm, sparsely puberulent; calyx segments 4.5-7 mm, margin entire.

纸质，无毛的叶片干燥，除被微柔毛的脉背面稀疏，边缘全缘在残波状的具小齿或的不清楚之外；花序梗6-16厘米，疏生微柔毛；花萼裂片4.5-7毫米，边缘全缘。

Lower leaves entire or repand; fruit torulose, with stellate and subsetose simple trichomes; subapical horns 0.5-1.8(-2.2) mm, erect or divaricate-ascending, straight; valves not extended beyond horns into stylelike apex

没有突起或瘤的分枝；花序通常超过5厘米；叶缘具深波状有齿，用5-8 对的次脉。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
