石韦（Pyrrosia lingua(Thunb.)Farw.）、截基石韦（Pyrrosia subtruncata Ching in Bull）、光石韦（P. calvata(Bak.)Ching.）、绒毛石韦（P. subfurfuracea（Hook.）Ching）、庐山石韦（Pyrrsia sheareri(Bak.)Ching）、柔软石韦（P. porosa (C.Presl)Hovenk）和平绒石韦（var.mollissima(Ching)Shing in W.T.Wang(Bowennia:erroIala) 对石韦、截基石韦、光石韦、绒毛石韦和庐山石韦的叶柄基部、中部和顶部进行横切，发现石韦属植物叶柄的横切而为圆形或近圆形，表皮下有厚角组织，石韦属植物叶柄各部位分体中柱数目不一样，大多都是基部较多，横切面上都有两个较粗大分体中柱，与其他小分体中柱排列成典型或不典型的“” ，木质部管胞呈“一”字形或弧形。维管束为周韧维管束，木质部由筛胞、薄壁细胞组成，韧皮部由筛分子、纤维、薄壁细胞组成，与纤维和薄壁细胞相间排列，筛胞分子的横切面形状为多边形或近圆形。5种石韦叶柄粗细不一样，光石韦和绒毛石韦叶柄粗壮，分体中柱也相对较多。 刚刚走进科研道路，遇到很多困难，最主要的是我的英语不是很好，翻译文章毫无头绪，希望前辈们多多指点谢谢 |

| To the cyclophorus lingua, the truncation base cyclophorus lingua, the light cyclophorus lingua, the down cyclophorus lingua and pyrrosia sheareri's petiole base, middle and the crown carries on the transverse cutting, discovered that the cyclophorus lingua is the plant petiole the transverse cutting, but is the circular or near circular, under the epidermis has the collenchyma, the cyclophorus lingua is the plant petiole various spots fission stele number is dissimilar, mostly is the base are many, on cross section two thick fission stele, with other small fission stele arrangement already promulgated law code or atypical “”, the xylem tracheid assumes “one” the glyph or the arc. Bundle for week strong Bundle, the xylem by the sieve cell, the parenchyma cell is composed, the bast by sieves the member, the textile fiber, the parenchyma cell to be composed, with the textile fiber and the parenchyma cell interaction arrangement, the sieve cell member's cross section shape is the polygon or near circular. 5 kind of cyclophorus lingua petioles thick thin are dissimilar, the light cyclophorus lingua and the down cyclophorus lingua petiole is sturdy, the fission stele relatively are also many. |

On the base of the petiole, and the top of the central cross section the Pyrrosia lingua(Thunb.)Farw、Pyrrosia subtruncata Ching in Bull P. calvata(Bak.)Ching.、P. subfurfuracea（Hook.）Ching and Pyrrsia sheareri(Bak.)Ching）、 and found that plants Pyrrosia petiole cross-section for the round or nearly round, subepidermal thick horn, Pyrrosia leafstalk plant in various parts of the split is not the same as the number of columns, most of them are the base of the more surface cross-section has two thick body Oita columns, and other small sub-body arranged in columns typical or not typical "," tracheid xylem was "one" or curved shape. Vascular bundle vascular bundle for the week of tough, xylem by sieve cells, parenchyma cells of the phloem sieve element from the fibers, thin-walled cells, and white fibers and parenchyma cells arranged molecular sieve cells of the cross-sectional shape for the polygon or nearly circular. Pyrrosia five kinds of different thickness petiole, light and villi Pyrrosia Pyrrosia sturdy petiole, split in the column is also relatively high. |
