摘要:

按照花粉外壁表面纹饰的不同,可将春黄菊族中下列各属分为两大类群:(1)明显具刺:亚菊
属Ajania Poljak., 女蒿属Hippolytia Poljak., 百花蒿属Stilpnolepis Krasch.。 (2)具退化状小刺:紊蒿属
Elachanthemum Ling et Y.R.Ling,线叶菊属Filifolium Kitam., 画笔菊属Ajaniopsis Shih,喀什菊属
Kaschgaria Poljak.),栉叶蒿属Neopallasia Poljak.,绢蒿属Seriphidium Poljak.。根据花粉形态特征,
我们认为将紊蒿属和百花蒿属仍分为两个相互独立的属较为适宜。

Abstract:

This paper deals with pollen grains of 9 chinese genera of Trib. Anthemideae
Cass., which include the genera: Ajania Poljak., Hippolytia Poljak., Stilpnolepis Krasch.,
Elachanthemum Ling et Y. R. Ling, Filifolium Kitam., Ajaniopsis Shih, Kaschgaria Poljak.,
Neopallasia Poljak., Seriphidium Poljak.,
     Pollen grains of these genera are isopolar, radially symmetrical, 3-colporate, NPC 345,
spheroidal, sometimes suboblate or subprolate. Polar axis 20.0-30.0μm equatorial axis 20.0
-30.0μm. The exine consists of three layers: tectum, columellae and nexine. Exine thickness
3.2-5.6μm, usually the columellae is the thickest.
     According to the differences of exine ornamentation, they are divided into two main
groups: 1. with distinct spines, including the genera Ajania Poljak., Hippolytia Poljak.,
Stilpnolepis Krasch., 2.with indistinct spinules, including the genera Elachanthemum Ling et
Y.R.Ling,   Filifolium Kitam.,   Ajaniopsis Shih,   Kaschgaria.,   Neopallasia Poljak.,
Seriphidium Poljak.
