auxiliary cell, but it may happen that two carpogonial branches are borne on the 
same supporting cell (fig. 508 D). DARBISHIRE (1895, p. 33) describes the carpogonial 
branch as four-celled, but he considers the supporting cell as the first cell of the 
carpogonial branch. — Numerous procarps were examined in specimens from various 
localities and gathered at different seasons; they showed considerable differences 
and the great majority 
of the procarps were 
not completely devel- 
oped. The procarps are 
easily recognizable by 
their abundant proto- 
plasmic contents and 
their staining power 
with hematoxylin. 
The supporting cell is

of the carpogonial 
branch; it must be

regarded as the auxiliary cell. In referring for details to my paper of 1929 and to 
the figures from there reproduced here, I shall only mention the principal facts. The 
carpogonial branches are often only two-celled (fig. 507), and the last cell is most 
frequently not developed as a carpogonium but roundish like the other cells of the 
branch, also in the three-celled carpogonial branches. The best developed carpo- 
gonial branches were met with in May and June, when long, projecting trichogynes 
were often observed (fig. 506). But most of the carpogonia observed had an abortive
