OUTLINES OF BOTANY. 



Plants which have usually conspicuous petals will occasionally appear 

 without any at all, either to the flowers produced at particular seasons, or 

 to all the flowers of individual plants, or the petals may be reduced to nar- 

 row slips. 



Flowers usually very irregular, may, on certain individuals, lose more or 

 less of their irregularity, or appear in some very different shape. Spurs, 

 for instance, may disappear, or be produced on all instead of one only of the 



One part may be occasionally added to, or subtracted from, the usual 

 number of parts in each floral whorl, more especially in regular polypetalous 

 flowers. 



Plants usually monoecious or dioecious may become occasionally herma- 

 phrodite, or hermaphrodite plants may produce occasionally unisexual 

 flowers by the abortion of the stamens or of the pistils. 



Leaves cut or divided where they are usually entire, variegated or spotted 

 where they are usually of one colour, or the reverse, must also be classed 

 amongst those accidental aberrations which the botanist must, always be on 

 his guard against mistaking for specific distinctions.
