Stewartianum IB Balfour & WW Smith（1922：127）及其近缘种Lilium stewartianum IB Balfour & WW Smith（1922：127）的连续变异。habaense（1986：51）和L. Xanthellum FT Wang et Tang（1980：283）。特别是L. habaense与L. stewartianum的雄蕊具有稍短的花丝（Wang et al. 1986）。黄百合与其他两个种的区别在于，蜜腺具小乳突，沿着内部花被片的基部形成两条沿着脊（图1）（Liang 1980）。我在田间观察到，花粉囊长度和蜜腺形态的变化是广泛的，基本上是连续的，并且取决于开花阶段。因此，在连续变化的基础上，我建议容纳L。habaense和L. xanthellum在L. Stewartianum
Continuous variation among Lilium stewartianum IB Balfour & WW Smith (1922: 127) and its close allies, L. habaense (1986: 51) and L. xanthellum FT Wang et Tang (1980: 283) have been observed by the author. In particular, L. habaense is distinguished from L. stewartianum on the basis of stamen having slightly shorter filaments (Wang et al. 1986). Lilium xanthellum is distinguished from the other two species by means of papillose nectaries that form two ridges along the bases of the inner tepals (Fig. 1)(Liang 1980). I have observed in the field that the variations in anthers length and nectary morphology are extensive, largely continuous, and dependent upon the phase of flowering. Therefore, on the basis of continuous variation I propose to accommodate L. habaense and L. xanthellum within L. stewartianum.
