" vexillar-pelory," as lias been seen in Lupinus poly- 

 phyllus, OytisuH Laburnum, Trlfollum repeiis, and 

 CUtoria ; (2) the " standard " and " keel "-petals 

 become developed like the "wings," giving rise to 

 " alar-pelory," as in Genista genuennis. In these peloric 

 flowers it was noticed that all the stamens were free. 



In the Labiatae three forms of pelory have been 

 observed. Peyritsch has paid special attention to the 

 matter in this order. He found that the peloric 

 flowers were nearly always terminal to the main axis 

 of the whole inflorescence, rarely lateral (PL XLII, 

 fig. 5) ; and the sepals of such flowers often leafy 

 and four in number, decussating with the two upper- 

 most pairs of foliage-leaves. Occasionally the peloric 

 flower was the terminal one of a half-verticillaster. In 

 most cases all the petals resembled the lateral petals 

 of the lower lip. In rarer cases, e. g. in the lesser 

 calamint (Calamintha Nepeta) they all resembled the 

 middle lobe of the lower lip, very rarely the petals of 

 the upper lip. 



Peyritsch also observed in Salvia Pitcheri and the 

 wild sage (8. pratensis) terminal bisymmetric peloric 

 flowers in which two opposite petals resembled the 

 lateral lobes of the lower lip of the normal flower, 

 whilst the two others resembled the middle lobe of 

 the lower lip. Such flowers Penzig terms "hemi- 

 peloric." 



In terminal peloric flowers of Streptocarpus (Ges- 

 neraceas) the dark-purple coloration of the three 

 anterior petals has occurred also in the tw^o posterior 

 ones. 



The most commonly cultivated and most striking 

 form of the " Gloxinia" (Sinnivgia speciosa) is that in 

 which the flower is erect and peloric, instead of having 

 the position and shape of all other normal flowers of 

 the same order (Gesneracere). 



In the Compositaa we frequently find the occurrence 

 of pelory in the corolla of the normally ligulate ray- 

 florets which then become not only actmomorphie, but
