Corm, a bulb-shaped, modified and swollen underground stem, in which reserve material is stored; e.g. a Crocus corm.
Corolla, the petals of a flower considered as a whole.
Corona, a circular rim within the corolla or perianth, such as the 'trumpet' of a Daffodil.
Cotyledons, the first pair of seed-leaves.
Crenate, applied to leaves with obtuse, rounded teeth, such as those of Violet and Ground Ivy.
Cryptogamic, plants reproduced by spores, like Ferns and Mosses, in which the stamens and pistils are wanting.
Cuneate Or Cuneiform, wedge-shaped; i.e. broadest above the middle and tapering towards the base.
Cuspidate, imperceptibly lengthened into a sharp point.
Cuticle, the outer skin of an animal or plant.
Cyme, an inflorescence in which the flowers are produced in successive, lateral axes; e.g. Myosotis, Lychnis.
Deciduous, applied to plants, and especially trees, whose leaves are shed each autumn.
Decurrent, applied to leaves which run down the stem.
Dehiscent, applied to fruits which open at one or more points to allow the seed to escape.
Dichotamous, applied to a stem, branch, panicle, or cyme which is forked again and again.
Digitate Leaves, are those whose lobes are disposed like the fingers of the hand, but from one centre, as in Lupine.
Dioecious Plants, are those having stamens and pistils in separate flowers on different plants.
Disc, the central part of a capitulum of Compositae; also the glandular space above the receptacle of some flowers.
Drupe, a fleshy, indehiscent fruit containing a stone in which the seed is enclosed; e.g. a cherry.
Ebracteate, without bracts.
Ecology, the study of plants in relation to their environment.
Elliptical, in the form of an oval with both ends tapering alike.
Emarginate, notched; usually applied to petals.
Endemic, peculiar to a district or country.
Endosperm, the store of food outside the embryo in certain seeds, and absorbed by it in germination.
Entire, applied to leaves which are not cut or toothed.
Epicalyx, the outer portion of a double calyx; e.g. in Dryas and Potentilla.
Epipetalous, applied to stamens borne upon petals.
Epiphyte, a plant which grows upon another, but not as a parasite. Lichens and many Orchids are epiphytes.
Evergreen, applied to plants with green foliage all the year, and to leaves which last more than one season.
Exalbuminous, seeds have no endosperm, and the embryo occupies the whole cavity.
Exstipulate, having no stipules.
Family, = Natural Order; a group of genera of greater or less affinity.
Fascicled, in bundles or tufts.
Filament, the slender stalk of a stamen.
Filiform, long and slender or thread-like.
Fistular, cylindrical and hollow, like many umbelliferous stems.
Flaccid, limp or flabby.
Flexuose, bent more or less in a zigzag.
Follicle, a carpel or seed capsule dehiscing longitudinally at the inner suture; e.g. Helleborus, Aconitum.
Free, not united.
Fruit, the seed or group of seeds with its whole covering.
Gall, a growth caused by an insect or fungus; e.g. an ' Oak apple'.
Gamopetalous Flowers, have the petals all united, as opposed to polypetalous.
Genus (Plural Genera), a group of species of greater or less affinity.
Gibbous, swollen at the base.
Glabrous, without hairs.
Gland, an organ of secretion.
Glandular, Hairs are those with enlarged apices containing a secretion, as in Drosera or Arnica montana.
Glaucous, covered with a pale bluish green bloom.
Glume, the bract which encloses the spikelet in Grasses and Sedges.
Glumella Or Glumule, the bract which forms the exterior covering of each flower of a spikelet in Grasses.
Gymnosperm, a flowering plant whose ovules are not enclosed in carpels. The Coniferce are the chief Gymnosperms.
Gyngecium, the carpels or female organs of a flower considered as a whole.
Habit, the outward form, shape, or build of a plant.
Habitat, the kind of locality in which a plant grows. Not the locality itself, which may be called a station.
Herbaceous, not woody.
