Abstract:
Based onherbarium and field observations and transplant experiment, Stemona sessilifolia (Miq.) Miq. was found to be a highly variable species in morphological characters such as habit, leaf shape, and the relative size of inner two perianth segments and the outer two perianth segments. In particular, the habit depends on whether the plant is growing in an open habitat, when it remains erect, or under forests when it is at first erect but then adopts a scandent habit. Thus it is clear that S. sessilifolia is a variable species and that S. shandongensis D. K. Zang must be treated as conspecific with it.Based on herbarium and field observations and transplant experiment, Stemona sessilifolia (Miq.)

Abstract Based on herbarium and field observations and transplant experiment, Stemona
sessilifolia (Miq.) Miq. was found to be a highly variable species in morphological characters
such as habit, leaf shape, and the relative size of inner two perianth segments and the outer
two perianth segments. In particular, the habit depends on whether the plant is growing in an
open habitat, when it remains erect, or under forests when it is at first erect but then adopts a
scandent habit. Thus it is clear that S. sessilifolia is a variable species and that S.
shandongensis D. K. Zang must be treated as conspecific with it.

摘要 根据对直立百部Stemona sessilifolia (Miq.) Miq.大量标本的研究和野外调查及引种栽培观察, 结
合对山东百部Stemona shandongensis D. K. Zang模式标本产地的调查, 发现直立百部的形态性状是多变
的。研究表明它的习性受生境影响而多变, 从直立半灌木到蔓生都有; 叶型多变; 花通常出自叶腋, 而
花梗有时与叶柄, 甚至主脉合生; 内轮花被片大多明显大于外轮。山东百部的形态性状处于直立百部的
变异范围内, 因此作为独立的种是难以成立的, 应处理为直立百部的新异名。

臧得奎和彭卫东(1996)依据来自山东泰山三阳观、凌汉峰和长清的标本发表了百部
科Stemonaceae百部属Stemona Lour.一新种——山东百部Stemona shandongensis D. K.
Zang, 其成立的主要依据是茎蔓生, 叶倒卵形, 先端突尖, 花梗与叶柄及叶片基部贴生,
花被片不反曲, 宽达0.4–0.6 cm, 外轮2片较狭, 而与近缘种直立百部S. sessilifolia (Miq.)
Miq.相区别。作者对中国科学院植物研究所标本馆(PE)、江苏省中国科学院植物研究所
标本室(NAS)、中国药科大学植物标本室(CPU)、安徽大学生物系植物标本室(ANU)、安
徽师范大学生物系植物标本室(ANUB)、中国科学院华南植物研究所标本室(IBSC)、杭州
植物园植物标本室(HHBG)、江西省庐山植物园标本室(LBG)、中国科学院广西植物研究
所标本馆(IBK)中所有的直立百部标本进行了仔细检查, 并对直立百部的多个生长地进
行了野外调查, 如山东泰山(山东百部模式标本原产地)、南京栖霞山、安徽合肥大蜀山和
安徽琅琊山, 同时还将上述每地各十余株直立百部引种到浙江大学植物园内进行观察。

研究发现, 直立百部是一个在形态上有较大变异的种。在林下幼期直立(图1), 以后
逐渐倒伏(图2), 或变为蔓生状, 在阳光充足的开阔地, 也可长成直立半灌木状; 不同居
群间和不同个体间的叶片形态大小变异较大(图3), 从卵状椭圆形、倒卵形、椭圆形到卵
状披针形均有, 先端以急尖、具短尖或骤尖为多, 间或有渐尖、钝形等多种变化, 基部常
下延; 甚至同一植株上叶形也有变化, 基部的常较宽圆, 上部的较窄而长; 花单生, 通常
出自茎下部鳞片状叶腋内, 或同时出现在鳞叶内和茎上部叶腋内, 花梗下部有时与叶柄
合生, 甚至与叶主脉基部合生, 同一植株上可出现多种着生方式; 花被片4枚, 2轮, 狭卵
形或披针形, 长1.3–1.8 cm, 外轮较狭, 宽0.35–0.55 cm, 内轮较宽, 宽0.4–0.65 cm, 或内
外2轮近等大, 同一植株上也有变化。从引种栽培的情况来看, 60多株植株中, 2005年有17
株开花, 共有花31朵, 其中来自琅琊山6株7朵, 栖霞山7株19朵, 南京中山植物园1株1朵,
泰山三阳观和黑龙潭3株4朵。所有观察的花内轮被片都大于外轮, 与陈汉斌(1990)对直立
百部的记载是一致的。在所有已观察的花中, 内轮花被片明显宽于外轮的有26朵, 内外两
轮几乎等大的只有5朵; 花被片的反曲现象只出现在花开放时的3–5天内, 此后花被片逐
渐闭合, 从而类似花蕾期的形态(图4)。从上述可见, 山东百部的主要特征处于直立百部
的变异范围内, 因此我们认为以茎蔓生, 叶倒卵形, 花梗与叶柄及叶片基部贴生, 花被片
不反曲, 宽达0.4–0.6 cm, 外轮2片较狭等性状为依据发表的新种山东百部是不能成立的,
应将其作为直立百部S. sessilifolia (Miq.) Miq.的异名来处理。
山东百部S. shandongensis的模式标本原存放在山东农业大学植物学教研室的标本柜
内, 作者曾经两次前往查看, 但是均未能找到, 后与臧先生联系, 被告知模式标本和其他
几份标本在校园搬迁过程中遗失。作者对其模式标本原产地, 以及南京、安徽滁州琅琊
山和合肥大蜀山等地直立百部的植株进行野外观察和移植, 结合标本馆查看标本, 最后
对山东百部S. shandongensis进行了归并处理:
