24 Brown: Apogamy in Phegopteris polypodioides 



hairs or outgrowths frequently formed at the base of the first 

 leaf or leaves of the young sporophytes. Figs. 1-4 show the 

 development of one of these apogamous sporophytes. In this 

 case the prothallium was lobed and the apogamous sporophyte 

 developed at the center of the cushion as a cellular mass (Fig. i). 



Figs. 1-6 



From this cellular mass, seven normal leaves were developed 

 before a root was formed. Soon after the first root formed, 

 another began to develop (Fig. 4). Meanwhile the old prothall- 

 ium became greatly reduced in size. The subsequent growth 

 of the apogamous sporophyte was normal and rapid. Figs. 

 5 and 6 represent other examples of apogamous sporophytes.
