| 摘 要： | 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.
