Inflorescence terminal, a thyrse or raceme, often lax; bracts each subtending a cincinnus of flowers, or flowers replaced by bulblets; bracteoles free to base.

In this research, we employed shoot-tips of wild Chinese tulip tree in Mount Emei as explants for tissue culture, and mesured the content changes of super oxygen-anion free radicals O2(superscript -, hydrogen peroxide (H2O2) and malondialdehyde during the secondary culture.

本研究以峨嵋山野生鹅掌楸茎尖芽为外植体进行组织培养，并对其继代培养再生过程中超氧阴离子自由基O2 (上标-、过氧化氢(H2O2)和丙二醛含量的变化进行了测定。

Inflorescences racemelike or spikelike; peduncle base sometimes with persistent bud scales; rachis usually slightly zigzagged.

The excised leaf of Phalaenopsis RSW1 was used as explants, the effects of basic media, kinds and concentrations of 6-benzyl aminopurine (6-BA) and thidiazuron, dark culture phase, and leaf age on adventitious shoot regeneration from leaves of Phalaenopsis RSW1 were investigated.

以蝴蝶兰品系RSW1离体叶片为外植体，探讨了基本培养基、6-苄基腺嘌吟(6-BA)和噻重氮苯基脲、暗培养时间及叶片生育期对叶片不定芽发生的影响。

Stamens usually twice as many as petals and in 2 whorls, rarely as many as petals by loss of 1 whorl, isomorphic or dimorphic; filaments distinct, often geniculate, inflexed in bud; anthers typically 2-celled, introrse, basifixed, dehiscent by 1 or 2 apical pores or by short longitudinal slits; connective often variously appendaged.

雄蕊通常是花瓣数量的两倍并且2轮，有时1轮而与花瓣同数，同形或二形；花丝离生，通常膝曲，在芽期内折；花药通常2室，向内，基着，通过1-2顶孔或短纵裂裂缝开裂（Astronia ，Memecylon；药隔通常有不同的附属物。

Bud scales at base of branchlets appressed; 1st-year branchlets glabrous.
