CLASSIFICATION OF PLANT ABNORMALITIES ^^^ 



Apostasis. — The monstrous disunion of parts normally united as 

 in the elongation of a flower axis, as a result of which the whorls are 

 transformed into spirals. One, however, uses the term for the sepa- 

 ration of single floral phyllomes, for example single sepals from the 

 calycine whorl. 



Atrophy. — Wasting away; degeneration of organs; abortion. 



Autophyllogeny (Ch. Morren). — The budding of one leaf from 

 another, as from the midrib. 



Balance Organic (Moquin-Tandon). — One uses this expression for 

 cases that by atrophy of single organs of a plant is compensated by 

 h3^ertrophy of others. 



Biastrepsis (C. Schimper). — This is analogous to the torsion, or 

 twisting of other authors. 



Blastomany (A. Braun). — Abnormal tendency of single plant 

 individuals to develop an unusual number of leaf buds (axillary or 

 adventitious). 



Calycanthemy (Masters).- — Transformation of sepals to petaloid 

 structure. 



Calyphyomy (Ch. Morren). — Adhesion of one or all of the sepals to 

 the back of the petals. 



Cenanthy. (Ch. Morren). — Kevos = empty + avOos = flower: Abor- 

 tion, or suppression of the stamens and pistils of a flower, leaving the 

 perianth empty. 



Ceratomany. — ^Abnormal formation of horn-like, or hooded, fre- 

 quently nectariferous structures in a flower. Clos has employed the 

 same term for the increase in the spurs in many families (Orchzdace.*;). 



Chellomany (Ch. Morren) .'—The doubling of the lip, or labellum, 

 in orchids, as in Orchis morio. 



Chloranthy. — The transformation, or change of all or most of the 

 floral parts into leaf-hke green parts; frondescence. 



Chorisis. — The separation of a leaf or phylloid part into more than 

 one; dedoublement, doubling. 



Cladomany. — ^An abnormally richly branched plant. 



Cohesion. — A union between the members of one and the same 

 whorl (particularly in flowers), or between the parts of a composite 

 organ. 



Coiyphylly. — An abnormality in which a leaf ends the axis. This 

 leaf is sometimes colored.
