344 Burt . — The Development of 
Phalloideae has been recently made by A. Moller 1 , still, up to 
the present time, only two of the Phalleae have been described 
and figured in their youngest stages, on account of the great 
difficulty of procuring such stages. Both investigations were 
made by Ed. Fischer. The first of these, published in 1890, 
was on Ithyphallus impudicus 2 , and the second, in 1895, on 
Mutinus caninus 3 . In both these investigations, however, 
the supply of material was deficient in important young stages. 
In the case of I. impudicus , this resulted in an erroneous view 
of the course of development at a point of great importance 
in determining the relationship between the Phalleae and 
Clathreae. A more correct view is presented in the recent 
paper on M. caninus , yet here also the lack of closely 
connected stages compels the author to make the reserva- 
tion that the course of development outlined in the earlier 
paper may, after all, be the true one, thus leaving the question 
still open. But these points, and that in regard to the origin 
of the gleba, will be treated more explicitly in the following 
pages. 
The material used in my investigation was collected in 
Somerville, Mass., in July, 1894. In this connexion I desire 
to express my thanks to Mr. B. M. Duggar and to Mrs. H. A. 
Ricker for directing me to a locality where this plant — which, 
in our region, is usually found growing solitary or in clusters 
of but few individuals — was growing in great luxuriance and 
abundance in a neglected area. 
. Through the kindness of Prof. Farlow this material has 
been compared with authentic specimens of Corynites Rave - 
nelii , B. and C., in the Curtis Herbarium, and it is undoubtedly 
of the same species. There does not seem to be good ground 
for regarding C. Ravenelii , B. and C., as specifically distinct 
from Mutinus caninus (Huds.), Fr.
