ON VARIEGATION IN PLANTS. 
Amorpha glabra, var. foliis iritervenio-flavo-reticulatis. 
Note. This is also one of the most beautiful forms of variegation. 
B. Nerves and veins discoloured, intervenium green. 
Ptelea trifoliata, var. foliis venis-flavo-reticulatis. 
Cytisus triflorus, var. foliolis venis-flavo-reticulatis. 
Pyrus Malus, var. foliis albo-reticulatis. 
Sambucus nigra, var. foliis venis-albo-aut flavo-retieulatis. 
Acer campestris, var. foliis albo-reticulatis. 
Oxalis acetosella, var. foliis venis-albo-reticulatis. 
Geum urbanum, var. foliis flavo-reticulatis. 
Note. This is also one of the most beautiful forms of vegetation. 
VII. Leaves vittate, striped with longitudinal parallel or converging bands. 
Funkia lancesefolia, var. foliis albo-vittatis. 
Hemerocallis fulva, var. foliis albo-flavo-purpureo-vittatis. 
Fritillaria Imperialis, var. foliis albo-vittatis. 
Convallaria majalis, var. foliis albo-vittatis. 
Digraphis aruudinacea, var. foliis albo-purpureo-vittatis. 
Note. Many other monocotyledonous plants have this form of variegation, which, physio- 
logically viewed, belongs to those in which the influence of the nerves is all-powerful ; for in 
Funlda ovata, for instance, and Convallaria majaUs, the nerves only are variegated ; while in 
Digraphis it is the intervenium which is white. 
VIII. Leaves marbled, with three or four tints at the upper surface, distributed on the paren- 
chyma between the principal nerves, and following their direction. 
Viburnum Lantana, var. foliis flavo-vir idi, flavo-niarmoratis. 
Quercus Robur, var. foliis albo-flavo-marmoratis. 
Acer rubra, var. foliis albo-flavo-viridi-marmoratis. 
Acer pseudo-platanus, var. foliis flavo-viridi, rubro-albo-marmoratis. 
^Esculus Hippocastanum, var. foliis flavo-albo-marmoratis. 
Prunus Laurocerasus, var. foliis flavo-viridi, flavo marmoratis. 
Crataegus Oxyacantha, var. foliis albo-flavo-rubro-marmoratis. 
Ulmus campestris, var. foliis albo-flavo-viridi-marmoratis. 
Note. This is the commonest of all forms of variegation ; it is frequent in nearly all trees, but 
in herbaceous plants somewhat more rare. 
IX. Leaves or leaflets, white, yellow, or red at one side of the mid-vein, and the other green. 
Viburnum dentatum, var. foliis flavo-dimidiatim-variegatis. 
Betula nigra, var. foliis flavo-purpureo-dimidiatim-variegatis. 
Ulmus glabra microphylla, var. foliis flavo-dimidiatim-variegatis. 
Syringa vulgaris, var. foliis albo-dimidiatim-variegatis. 
Euonymus europseus, var. foliis flavo-dimidiatim-variegatis. 
Rhanmus Frangula, var. foliis flavo-purpureo-dimidiatim-variegatis. 
Buxus sempervirens, var. foliis flavo-dimidiatim-variegatis. 
Acer campestris, var. foliis flavo-viridi-purpureo-variegatis. 
1 * * Action proceeding from the base to the summit, from the summit to the base, or by a transverse 
band, perpendicular to the principal nerves. 
X. Leaves with the base only or the apex only discoloured. 
A. Discoloured at the base. 
Cornus san guinea, var. foliis basi-albo-variegatis. 
Cornus alba, var. foliis basi-albo-variegatis. 
B. At the apex. 
Cornus mascula, var. foliis apice-albo-variegatis. 
XL Leaves fasciated, having one or several discoloured transverse bands perpendicular to the 
direction of the midrib. 
Cornus mascula, var. foliis albo-fasciatis. Viburnum dentatum, var. foliis flavo-fasciatis. 
' * * * Action general, pervading the ichole of the leaf. 
XII. Leaves entirely yellow or white
