Comment on E. paniculata, E. maculata and E. longipes :
In regard of the protologues of E. paniculata Gray and E. maculata Rose, Walther's original decision to synonymise the latter was very appropriate. However instead of sticking to it he unnecessarily redescribed E. maculata from a plant not from the type locality and another E. maculata clone as spec. nov. E. longipes. A species occurring in more than a dozen Mexican states cannot help being somewhat variabel regarding size and shape of the leaves, however as numerous herbarium specimens from a great number of different localities clearly show, the inflorescences - often very diverse on one and the same plant - of plants in the northern states do not differ from those of plants in central Mexico. It is pointless to treat E. maculata as an independent species. And E. longipes is best completely disregarded – Felipe Otero's re-collection of 1970 of this plant at the type locality resulted in a plant with extremely short pedicels !
