lvi OUTLINES OF BOTANY. 
Plants which have usuaily 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 
etals. - 
‘ 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 monecious or dicecious 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,
