tubular perianth {P,p), on which is inserted a yellow outgrowth 

 — the corona (cti). 



In the SNOWDROP {Galanthus nivalis), the bulb consists 

 of the swollen bases of the two foliage-leaves of the previous 

 year inserted on a short axis. The plant has only two foliage- 

 leaves each year. The inflorescence-axis bears a spathe and a 

 single pendulous flower. The two whorls of the perianth are 

 composed of separate perianth-leaves ; the outer whorl differs 

 in appearance from the inner whorl, so that we may speak 

 definitely of three sepals and three petals. The stamens are 

 not inserted on the perianth, they are epigynous. Each anther 

 opens by two terminal pores. (See also page 32.)
