"The Origin of Species by means of Natural Selection, 6th Edition"

In different plants the parts of the flower are
homologous, and in general these parts are regarded as homologous with
leaves.
HOMOPTERA.--An order or sub-order of insects having (like the Hemiptera) a
jointed beak, but in which the fore-wings are either wholly membranous or
wholly leathery, The Cicadae, frog-hoppers, and Aphides, are well-known
examples.
HYBRID.--The offspring of the union of two distinct species.
HYMENOPTERA.--An order of insects possessing biting jaws and usually four
membranous wings in which there are a few veins. Bees and wasps are
familiar examples of this group.
HYPERTROPHIED.--Excessively developed.
ICHNEUMONIDAE.--A family of hymenopterous insects, the members of which lay
their eggs in the bodies or eggs of other insects.
IMAGO.--The perfect (generally winged) reproductive state of an insect.
INDIGENES.--The aboriginal animal or vegetable inhabitants of a country or
region.
INFLORESCENCE.--The mode of arrangement of the flowers of plants.
INFUSORIA.--A class of microscopic animalcules, so called from their having
originally been observed in infusions of vegetable matters. They consist
of a gelatinous material enclosed in a delicate membrane, the whole or part
of which is furnished with short vibrating hairs (called cilia), by means
of which the animalcules swim through the water or convey the minute
particles of their food to the orifice of the mouth.
