Psilophyta (division) (Plantae (kingdom), Eukaryota (domain), ... Living Organisms (hierarchy name)) |
|
Note: Group consisting of two extant genera, Psilotum and Tmesipteris. They are chiefly tropical, clump-forming plants of skeletal appearance resembling whisk brooms. These plants are primitive in structure, lacking both roots and leaves, or having structures on the aerial shoot that are foliar. They are structurally similar to the fossil genus Rhynia. Recent molecular systematic studies suggest that the family is actually related to primitive ferns.

Additional Notes: |
|
| Chinese (traditional) ..... 含兩個現存屬的植物群，分別為松葉蕨屬與梅溪蕨屬；主要為熱帶的叢生植物，纖瘦如撢帚。這些植物的構造原始，不具根與葉，或在氣生芽上長有葉狀構造，與雷尼蕨化石屬的結構相似。近來的分子系統研究指出，松葉蕨門實際上與原始蕨類有關連。 |
| Dutch ..... Group van twee bestaande genera, Psilotum en Tmesipteris. De soorten uit deze stam komen voornamelijk in de tropen voor. Het zijn skeletachtige planten die groepen vormen en op strobezems lijken. Ze hebben een primitieve structuur zonder wortels en bladeren of hebben andere structuren op de spruiten die op bladeren lijken. Morfologisch lijken ze op het fossiele genus Rhynia. Recent systematisch moleculair onderzoek duidt erop dat ze verwant zijn aan primitieve varens. |
