以该属为研究基础，对所有代表种进行分析。除了在那些少数情况下，其中它们超过50个spp。对1287个属的种子内部形态进行了研究。特别注意的是集中在胚胎的大小，形状和位置在其与胚乳的关系。根据新的种子分类系统（包括12个基本种子类型），绘制了所有有胚乳属种子的横、纵剖面图，并将这些图分成67个图版。该报告提出了种子形态的系统发育意义的讨论，并包括一个“家谱”的种子描绘的12个种子类型作为连续的发展阶段沿着2条主要的进化路线。
Using the genus as the base of study and analyzing all representative spp. except in those few instances wherein they exceeded 50 spp. per genus, the gross internal morphology of seeds of 1287 genera was studied. Particular attention was focussed on the size, shape and position of the embryo in its relation to the endosperm. Drawings of cross and longitudinal sections of seeds were made in all genera having endosperm and the drawings were grouped into 67 plates according to a new system of seed classification involving 12 basic seed types. The report presents a discussion of the phylogenetic significance of seed morphology and includes a "family tree" for seeds depicting the 12 seed types as successive stages of development along 2 major lines of evolution.
