Con motivo de la síntesis de Anthyllis para Flora iberica ha sido necesario revisar la nomenclatura y la taxonomía del agregado de Anthyllis henoniana, en el que se han incluido las Anthyllis sufruticosas inermes con glomérulos pauciflorus (4-7 flores), hojas subdísticas y folíolos pulvinulados. En este grupo se han reunido dos especies (A. henoniana Coss. y A. subsimplex Pomel) descritas de las estepas desérticas argelinas, junto a otra (A. sericea Lag.) descrita de los matorrales pedregosocalcáreos de Albacete. Los tres nombres han recibido diversos tratamientos taxonómicos, desde ser considerados como coespecíficos (JAFRI & ELGADI, Fl. Lybia 86:114.1980), hasta como tres entidades específicas independientes [BATTANDIER in BATTANDIER & TRABUT, Fl. Algérie (Dicot.) 1:250. 1889), o como dos especies distintas (GREUTER and al., Med-Checklist4:6-7.1989].

Some years ago a fossil lake basin was found in the northeastern part of the former Rhine-pied- mont-glacier, situated between the endmoraine system ofthe elassical Riß- andWürm glacia- tions, respectively. The lacustrine sediments contain the pollenflora ofthe Eemian interglacial. They are intensively thrusted. These sediments are eovered by a loam-layer, rieh in elasts. The thickness of this loam-layer varies between at least 170 and 400 cm. It consists in its major part of loess-loam and solifluction material. Yet just on top of the lake sediments mentioned an in- tensively compressed loam, characterized by quarzgrains with all features of glacially pressed material, together with striated elasts is met with. It strongly resembles atil!. Ifthis is true, the stratigraphie division ofthe last glaciation strongly deviates from the hitherto accepted scheme, incorporating an early glacier advance, long before the elassical young-endmoraine systems of the Würm glaciation were formed.
