224 REGULAR PELORIA. 



character, as in Dendrobkim normale, Oncidmm heterau' 

 thumy Thelymitray etc. Fig. 121, reduced from a cut in 

 tlie ' Grardeners' Chronicle,' 1854, p. 804, represents an 

 instance of this kind in Cattleya marginata. 



From the same journal the following account of 

 a case of peloria in Fhalcenopsis Schilleriana is also 

 cited as a good illustration of this peculiar change. 

 The terminal flower differed entirely from all the 

 others ; instead of the peculiar labellum there were 

 three petals all exactly ahke, and three sepals also 

 exactly alike ; the petals resembled those of the other 

 flowers of the spike, and the upper sepal also ; but the 

 two lower sepals had no spots, and were not reflexed 

 as in the ordinary way : thus, these six parts of the 

 flower were all in one plane, and being close together 

 at their edges, made almost a full round flower ; the 

 column and pollen-glands were unaffected. Pro- 

 fessor Reichenbach also exhibited at the Amsterdam 

 Botanical Congress, of 1865, a flower of Selenipedium 

 caudatum with a flat lip. 



M. Gris^ has placed on record some interesting cases 

 of peloria of this kind in Zingiber' zerumbet ; in the more 

 complete forms the androecium or staminal series was 

 composed of six distinct pieces, the three inner of 

 which were fertile, while in the ordinary flower the 

 androecium is composed of two pieces, '* a lip" and a 

 fertile stamen. "Is it not a matter of regret," says 

 M. Gris, *' to be obliged to call the latter the normal 

 flower?" 



Under this head may likewise be mentioned those 

 cases in which the normal, or at least the typical sym- 

 metry of the flpwer is restored by the formation of 

 parts usually suppressed ; thus Moquin cites an abnor- 

 mal flower of Atripleoi^ hortensis described by M. Fenzl 

 as having a true calyx within the two bracts that 

 usually alone encircle the stamens. Adanson, also 

 cited by Moquin, found a specimen of Bocconia with a
