APOGAMY IN ATAMOSCO 
LULA PAcE 
(WITH PLATES XIII AND Xtv) 
Atamosco texana Greene (Zephyranthes texana) is one of the 
Amaryllidaceae, and is called amaryllis, atamosco lily, or rain lily. 
The so-called rain lilies in this region bloom in the summer and 
autumn for a few days after each rain. This one is not quite so 
well known here as the white lily, Cooperia Drummondii, which is 
about twice the size and much more abundant in this locality; but 
100-200 miles farther-west Atamosco is the more plentiful. ; 
The first collection of material was made for clas> ~ 
ovules and embryo sac are very large; but very early 1 une prepala- 
tion of this material interesting things were noticed. So the 
material on hand was carried to Bonn and worked over there so far 
as the stages permitted. I regret exceedingly not being able to 
complete it at that time under the direction and with the suggestions 
“and criticisms of Professor SrrasBuRGER. But it gives me great 
pleasure to acknowledge my indebtedness to him for his kindly 
interest and stimulating suggestions during the first part of the 
work. 
Material 
The material was all collected in one locality, near Waco, 
Texas; and in this particular place Atamosco is quite abundant over 
two or three acres. But as the flowers are solitary and often pre- 
cede the leaves, it is not easy to find young stages. I now have 
plants under cultivation and hope to get these desired stages later. 
Two collections have been made, one in 1909 and the other m 
tg11. The intervening year I was abroad and no collection could 
be made. The material was fixed in chromacetic acid (0.25 per 
cent chromic acid and 1 per cent acetic acid). In some cases about 
10 drops of 1 per cent osmic acid was added to 50 cc. of the above. 
Alcohol-acetic (three parts absolute alcohol and one part acetic 
acid) and alcohol-formalin (two parts of so per cent alcohol and one
