The late middle Eocene lacustrine filling of a maar lake at Eckfeld (Eifel Hills, Rhineland-Palatinate, western Germany) has provided four specimens of male inflorescences (catkins) in different stages of anthesis, each with pollen preserved in situ. The appearance of the successive stages together with triporate pollen showing an irregular surface and a myricoid micro-ornamentation clearly suggests an assignment of the fossil catkins to the Myricaceae. The material is described as a new genus and new species and represents the oldest record of male catkins for the family. The in situ preserved pollen grains are comparable to dispersed grains of Triatriopollenites excelsus.

在埃克费尔德（德国西部的莱茵兰-普法尔茨州的埃菲尔山丘）的一个马尔湖中晚期始新世湖相充填提供了四个花序标本，分别位于花期的不同阶段，每个花序都保存在原位。连续阶段的出现以及呈不规则表面和杨桃体微装饰的三倍花粉清楚地表明化石柳絮属于杨梅科。该材料被描述为一种新的属和新的物种，代表了该家族中雄性柳絮的最古老记录。原位保存的花粉粒相当于三角松花粉的分散粒。
