It is quite unreasonable reducing Elachanthemum Y. Ling et Y. R. Ling into
Stilprolepis Krasch. and it is so wrong idea attributing the achenes and cupuliform corolla (as
a matter of fact, the cupuliform corolla is originally from the Stilpnolepis Krasch., not from
Elachanthemum Y. Ling et Y. R. Ling) of Elachanthemum Y. Ling et Y. R. Ling to “earlier
Development” in the paper published in Act. Phytotax. Sin. 23(6): 470-472. 1985.
In Elachanthemum Y. Ling et Y. R. Ling, bracts of capitula herbaceous, obviously floccose
on the abaxial surface and membranaceous only on the margin, corolla of bisexual florets tubu-
lar, achenes oblique, obovoid, and the exine of pollen grains minutespinulate, but in Stilpnole-
pis Krasch., on the contrary, whole bracts membranaceous, glabrous, corolla of hermaphrodite
florets cupuliform or campanulate, achenes long-clavate or fuciform and the exine of pollen grains remarkably spiny. 相似文献

虽然玄参科的马松蒿Xizangia serrata D.Y.Hong与齿叶翅茎草Petrygiella artschioides Hand.-Mazz.系同物异名,但齿叶翅茎草与翅茎草属其余4种植物在习性、叶、花萼等外部形态上有显著差异,在种皮方面的差异尤为突出。马松蒿属Xizangia 作为属的地位是合适的。因此,本文作了一个新组合,即XI-zangia bartschioides(Hand.-Mazz.)D.Y.Hong,而把Ptertrygiella bartschioides Hand.-Mazz.和Xizangia serrata D.Y. Hong均作异名处理。 相似文献
