notice occurs in a hybrid of the saffron (Crocus sativus). Stigmatic 

 characters in this plant have wandered so far that not only the anthers 

 and floral bracts, but also the foliage leaves are sometimes surmounted 

 by portions of clearly characterized stigma, furnished with papillae; 

 and even the sheaths below the leaves are tinged with saffron color. 



3. Translocation may be lateral. 



Peloria, whether regular or irregular, illustrates this form of 

 homoeosis. In the well-known Uropedium Lindenii (Selenipedium 

 cauda turn, Orchidaceae) the form of the remarkably long pendent 

 petals invades the labellum, entirely subduing the saccate character 

 of that member and converting the strongly zygomorphic into an 

 actinomorphic corolla. 19 Contrariwise, the irregular member may 

 impose its form upon the remainder of the corolla, as in the well- 

 known peloric Linaria vulgaris. 



4. The invasion of migrating characters may be partial in any 

 degree. 



The curious modifications of the pistil and its contents in abnormal 

 Drosera intermedia illustrate this truth in several different ways. 20 

 As vegetative influences begin to evince their presence in the flower, 

 the first modification of the gynoecium is an elongation of the ovary, 

 especially its lower part. The carpels, while still concrescent, ovulif- 

 erous, and terminated above by the usual stigmatic apparatus, in a 

 slight degree respond to the influx of foreign morphogenetic forces 

 by the lengthening of their basal portions, corresponding to the 

 petioles of foliage leaves: the carpels sensibly approach a petiolate 

 condition. In flowers yet more affected the carpels separate in 

 various degrees, finally falling apart altogether; their bases become

complanate and spathulate; the ovules after suffering a series of 

 changes are finally replaced by tentacles ; and the styles and stigmas, 

 still retained even when the carpel-foliage-leaves spread horizontally 

 from the center of the flower in rosette fashion, lose much of their 

 rightful character. Thus is the gynoecium transformed step by 

 step into a whorl of leaves. The metamorphosis of each part of
