The Seed of Cardiospermum halicacabum L. A Criticism
Acta botanica neerlandica , Volume 9 - Issue 3 p. 330- 332
Van der Pijl (1957) has criticized my paper (1946) on the “Embryology of Cardiospermum halicacabum L.” in different points. I feel it is my duty to discuss the ideas which van der Pijl put forward with regard to my figures, which were drawn with the aid of a camera lucida. I wish to make three remarks in this respect.
