He also says that such a diploid egg is in reality already fertilized, 
und zwar in dem Sinne, dass der Zustand, den die Befruchtung in seiner 
Mutterpflanze schuf, in ihm noch fortdauert, da er nicht durch den Vorgang 
der Reduktionsteilung, gewissermassen durch Entfruchtung, aufgehoben 
wurde 
It is already from its organization endowed with the double 
number of chromosomes, so it goes on, so far as the chromosome 
number is concerned, developing like the cells of a bud or an 
adventive embryo. The development of these Anlagen would 
hardly be compared to genuine parthenogenesis, in spite of the 
fact that no fertilization takes place here. But WINKLER used a 
different terminology, based on a somewhat different conception, 
especially with reference to the importance of the haploid or 
diploid number of chromosomes. He (29) would call this “somatic 
parthenogenesis.”’ He defines parthenogenesis (p. 11) as 
die apomiktische Entstehung eines Sporophyten aus einem Ei, und zwar (a) 
somatische parthenogenesis, wenn das Ei einen Kern mit der diploiden, unre- 
ducierten chromosomenzahl besitzt (6) generative parthenogenesis, wenn der 
Kern des Eies mit der haploiden Chromosomenzahl ausgestattet ist. 
He defines apogamy as 
die apomiktische Entstehung eines Sporophyten aus vegetative Zellen des 
Gametophyten, und zwar (a) somatische Apogamie, wenn die Zelle oder der 
Zellkomplex, die den Sporophyten liefern, in ihren Kerne die diploide Chromo- 
somenzahl besitzen (b) generative Apogamie, wenn die Kern der Mutterzellen 
des Sporophyten nur die Haploide chromosomenzahl fuhren. 
That is, WINKLER would call the development, without the aid 
of a male gamete, of an egg (either haploid or diploid) partheno- 
genesis, the development of vegetative cells (from a gametophyte) 
apogamy. There can be no question concerning the latter, but 
there may be a difference of opinion as to whether the development 
of both diploid and haploid eggs without fertilization should be 
called parthenogenesis. 
In Atamosco the organization of the egg, with the exception of 
the presence of the diploid number of chromosomes, is perfect 5° 
far as morphological evidence goes. The whole egg apparatus 
is characteristically developed, being quite distinct in appearance
