So grafted trees, l. 167. Mr. Knight first observed that those apple and pear trees, which had been propagated for above a century by ingraftment were now so unhealthy, as not to be worth cultivation. I have suspected the diseases of potatoes attended with the curled leaf, and of strawberry plants attended with barren flowers, to be owing to their having been too long raised from roots, or by solitary reproduction, and not from seeds, or sexual reproduction, and to have thence acquired those hereditary diseases.[Back to Canto]

Enamoured Psyché, l. 223. A butterfly was the ancient emblem of the soul after death as rising from the tomb of its former state, and becoming a winged inhabitant of air from an insect creeping upon earth. At length the wings only were given to a beautiful nymph under the name of Psyche, which is the greek word for the soul, and also became afterwards to signify a butterfly probably from the popularity of this allegory. Many allegorical designs of Cupid or Love warming a butterfly or the Soul with his torch may be seen in Spence's Polymetis, and a beautiful one of their marriage in Bryant's Mythology; from which this description is in part taken.[Back to Canto]

While Beauty broods, l. 261.

Alma Venus! per te quoniam genus omne animantum
Concipitur, visitque exortum lumina cœli.

From the nectar'd cup, l. 268. The anthers and stigmas of flowers are probably nourished by the honey, which is secreted by the honey-gland called by Linneus the nectary; and possess greater sensibility or animation than other parts of the plant. The corol of the flower appears to be a respiratory organ belonging to these anthers and stigmas for the purpose of further oxygenating the vegetable blood for the production of the anther dust and of this honey, which is also exposed to the air in its receptacle or honey-cup; which, I suppose, to be necessary for its further oxygenation, as in many flowers so complicate an apparatus is formed for its protection from insects, as in aconitum, delphinium, larkspur, lonicera, woodbine; and because the corol and nectary fall along with the anthers and stigmas, when the pericarp is impregnated.

Dr. B. S. Barton in the American Transactions has lately shown, that the honey collected from some plants is intoxicating and poisonous to men, as from rhododendron, azalea, and datura; and from some other plants that it is hurtful to the bees which collect it; and that from some flowers it is so injurious or disagreeable, that they do not collect it, as from the fritillaria or crown imperial of this country.[Back to Canto]

With appetencies just, l. 271. As in the productions by chemical affinity one set of particles must possess the power of attraction, and the other the aptitude to be attracted, as when iron approaches a magnet; so when animal particles unite, whether in digestion or reproduction, some of them must possess an appetite to unite, and others a propensity to be united. The former of these are secreted by the anthers from the vegetable blood, and the latter by the styles or pericarp; see the Additional Note [VIII]. on Reproduction.[Back to Canto]

Of bright Vallisner, l. 280. Vallisneria, of the class of dioecia. The flowers of the male plant are produced under water, and as soon as their farina or dust is mature, they detach themselves from the plant, rise to the surface and continue to flourish, and are wafted by the air or borne by the current to the female flowers. In this they resemble those tribes of insects, where the males at certain seasons acquire wings, but not the females, as ants, coccus, lampyris, phalæna, brumata, lichanella; Botanic Garden, Vol. II.
