具鞘的

F. bidentis leaf was of isobilateral type, and had thicker epidermis cell wall and cuticle, obvious cryptopores, and highly developed palisade tissue, with typical C4-plant Kranz anatomy. The collenchymas and vascular tissue in stem and the aerenchyma in root were well developed. Secretory structure was found in all vegetative organs. According to the analyses of soil physical and chemical properties and relevant ecological factors, F.

结果表明：黄顶菊叶片表皮具较厚的角质层、下陷气孔，叶片为等面叶、全栅型，叶肉细胞环绕维管束鞘细胞紧密排列，是典型C4植物的Kranz花环结构；茎中厚角组织和维管组织发达，根中还存在通气组织；根、茎、叶中均存在分泌结构。

They all have the typical structure of leaf of C4 plant, but out of the ordinary is that the structure of the midrib is alike the parallel veins and there is a layer of fiber cells between the phloem and the bundle-sheath of vein in the midrib and big parallel veins while the outer wall of the bulliform cells is less cuticularized.

摘 要：以7个杂交狗牙根品种的叶片进行解剖研究，结果表明，各品种均具禾本科 C4植物叶片典型结构，其独特处是：中脉结构与平行脉相似；中脉维管束、平行脉大维管束的维管束鞘内侧韧皮部外有一层纤维细胞；泡状细胞外壁很少角化。

Filaments free, very short; anthers free or mostly connivent into a sheath around ovary, 2 anterior ones with spurlike or wartlike and nectariferous appendages at base, these extending into anterior spur, connectives produced apically into conspicuous, membranous appendages.

花丝离生，非常短；花药离生或多数在子房周围靠合成为鞘，前面2枚基部具距状或瘤状和分泌蜜汁的附属物，这些延伸进入前面的距中，药隔顶部生明显、膜质附属物。

Results (1)Most neoplasms in fourth ventricle had characteristic MRI appearances,such as meningioma,medulloblastoma,epidermoid cyst.

结果 (1)不同的中颅窝肿瘤各具不同MR特征性表现，如三叉神经鞘瘤、脑膜瘤、骨母细胞瘤等。

Leaves petiolate, sheath narrow; blade ternate-pinnate or pinnatisect, membranous; ultimate segments filiform to lanceolate.

叶具叶柄，鞘狭窄；叶片回三出羽状或羽状全裂，膜；末回裂片丝状的到披针形。

Neurothekeoma and plexiform fibrohistiocytic tumor are dermal neoplasms that share many clinical and histologic features and whose histogenesis is equally disputed.

神经鞘黏液瘤和丛状纤维组织细胞性肿瘤好发于皮肤，两者的临床特点和组织学特征有许多相同之处，但两者的组织发生仍具争议。

Culm internodes only apically pruinose; sheath scars glabrous; leaf blades 1.5–2.2(–2.8) cm wide, glabrous

节间只顶部具粉霜的Culm；鞘痕无毛；叶片1.5-2.2(-2.8)厘米宽，无毛 55

Leaves long-petiolate; petiole expanded at base into short sheath; blade orbicular or reniform.

叶具长叶柄；叶柄膨大的在基部成为短鞘；叶片圆形或肾形。

Base foliation sword form, long 20-50 centimeter, wide 2-4 centimeter, erect or bend a bit, without apparent midrib, virescent or celadon, often provide whitening, base ministry scabbard shape, constant belt is rufous, tip gradually pointed.

基生叶剑形，长20-50厘米，宽2-4厘米，竖立或稍弯曲，无明显的中脉，淡绿色或灰绿色，常具白粉，基部鞘状，常带红褐色，先端渐尖。

Proximal cauline leaves not sheathlike; sepals less than 4.5 mm; fruit shortly stipitate or sessile.

下部的茎生叶并非鞘状；萼片不到4.5毫米；果具短柄或无梗。
