the upper surface of the petal and the basal lobes of 

 the versatile anther ; in just the same way as the 

 organ bearing it was an intermediate structure between 

 a petal and an anther. In one petal the corona-lobes 

 were each obviously direct downward extensions, in 

 petaloid form, of the anther-lobes, while at the same 

 time continuous on the outer margin with the normal 

 ligular outgrowth from the petal ; and this outer 

 petaloid portion of the corona was a result of the outer 

 petaloid portion of the anther. This was, perhaps,

the best case for demonstrating the absolute oneness 

 of the anther-lobes with the corona, the texture and 

 colour of the normal corona being always present. In 

 another petal, besides the downward-pointing narrow 

 anther-lobes having the colour and consistence of a 

 corona, there were two upwardly-directed, broad, 

 petaloid lobes as well, so that in this case the corona 

 was divided into two parts, exactly corresponding to 

 the two parts into which the petal was divided, viz., 

 upper anther-lobes and lateral petaloid portions. In a 

 third petal the basal anther-lobes were partly poUeni- 

 ferous and partly corona-like (fig. 124),
