 opposite view, that the most higlily complex is the form whence 

 the less differentiated case of regular peloria is derived by a pro- 

 cess of degeneration, finds, so far as I know, no Avarranty, either 

 in organogeny or in anatomy. 



Regular Peloria. — 

 Prof, Asa Gray, as 

 before mentioned, has 

 described a case of 



peloria in 



regular 

 Cyprlpedium candi- 



dum associated Avith 

 a reduced number of 

 parts, forming thus a 

 regular symmetrical 

 and complete, but di- 

 merous, Orchideous 

 flower — the first ver- 

 ticil of stamens bar- 

 ren, the second an- 



theriferous, and alter- 

 nating with the car- 

 pels. Here we have, 

 as Gray remarks, 

 "clear, and perhaps 

 the first, direct de- 

 monstration that the 

 Orchideous typo 

 flower has two sta- 

 minal verticils, as 

 Brown always in- 

 sisted."* Mr.Tautz
