RASMUSSEN, F. N., 1985. The gynostemium of Bulbophyllum ecornutum (J. J. Smith) J.J. Smith (Orchidaceae) . Stages in the development of the gynostemium of Bulbophyllum ecornutum demonstrate that the pollinium stalk is a hamulus in this and in a closely related species, B. gibbolabium . A hamulus arises by apical growth and reflexion of the median carpel. Hamuli have recently been discovered in several orchid genera, and a transverse fold of the rostellar apex is already known from a large group of orchids. The closely related B. cornutum has a quite different gynostemium structure. 相似文献
