Abstract

DURING a recent visit to Madrid for another purpose, I was able to visit some of my colleagues there, and was delighted to find that research work in genetics was continuing. Prof. I. de Zulueta, in the intervals of hiding the more precious contents of the biological museum in cellars, was continuing his work on the polymorphic beetle Phytodecta variabilis. Prof. Galan, of Salamanca, was very appropriately breeding the explosive cucumber, Ecballium elaterium. This plant is hermaphrodite in one half of Spain, di” cious in the other. Crosses between a di” cious plant and hermaphrodites from different areas seemed to reveal the existence of strong and weak local races, differing, like those of Lymantria, in respect of sex-determining factors.
