Ever)* part of tllrk I)latlt whic~h, when removed, is capable of

The pl:>*tutl, or propagata,ble part, often detaches itself
naturall?-. (‘ertain willows shed their twigs, and these parts
falling in . dctachtable vegetative bodies or cells.
There art‘ whole ranges of plants that exist in cultivation
and :trc ;~bundant ly propagated independently of seeds. Even
though the plant produce good seed, the leafy and stem structures
may afford the quickest and easiest means of propagation.
The class of “bulb plants,” represented by the lilies
and ulnar)-llis aud gladiolus, are of this order. The hop is
habitually propagated by cut.tings, as are many of the ornamental
trees and shrubs ; special varieties of rhododendron
and the tree-fruits are multiplied and at the same time preserved
“ true to name ” by means of grafting ; the cranberry
is grown from slips : blackberry from root-cuttings J red raspberry
from suckers ; strawberry from runners; many kinds
of*I+gonias year after year by cuttings of stems and leaves ;
roses getltlrntiot-1 after generation by cuttings.
In great numbers of domestic plants, seed-propagation
rarely intervenes. The cultivator is so accustomed to this
fact that he rightly accepts it as the order of nature.
