Begonia, Geranium or Magnolia

Usage examples of genus.

But even admitting this derivation from a unity--a unity however not predicated of them in respect of their essential being--there is, surely, no reason why each of these Existents, distinct in character from every other, should not in itself stand as a separate genus.

The forest trees are almost solely the Ailanthus glandulosus and the Zelkowa keaki, often matted together with a white-flowered trailer of the Hydrangea genus.

Xylomelum pyriforme or native pear trees with their wooden fruit and unpleasant odour, and the Goodenia ovata with its dark serrated leaves and yellow flowers and the Pittosporum and Sassafras were all clasped together and held close by native jasmine, and up through it all the cabbage and bangalow palms and the Eucalyptus microcorys or tallow wood and the Swamp Mahogany or robusta of the eucalyptus genus stood into the humid air.

We may instance Rubus, Rosa, and Hieracium amongst plants, several genera of insects, and several genera of Brachiopod shells.

Genera which are polymorphic in one country seem to be, with some few exceptions, polymorphic in other countries, and likewise, judging from Brachiopod shells, at former periods of time.

Even with lichens removed, bryophytes is a busy realm, with over ten thousand species contained within some seven hundred genera.

In the Classical age - Locke and Linnaeus, Buffon and Hume are our evidence of this - the critical question concerned the basis for resemblance and the existence of the genus.

Why not bisect the unity, Motion, and so make Action and Passion two species of the one thing, ceasing to consider Action and Passion as two genera?

Conditions necessary for these movements--List of Genera and Families, which include sleeping plants--Description of the movements in the several Genera--Oxalis: leaflets folded at night--Averrhoa: rapid movements of the leaflets--Porlieria: leaflets close when plant kept very dry--Tropaeolum: leaves do not sleep unless well illuminated during day--Lupinus: various modes of sleeping--Melilotus: singular movements of terminal leaflet--Trifolium--Desmodium: rudimentary lateral leaflets, movements of, not developed on young plants, state of their pulvini--Cassia: complex movements of the leaflets--Bauhinia: leaves folded at night--Mimosa pudica: compounded movements of leaves, effect of darkness--Mimosa albida, reduced leaflets of--Schrankia: downward movement of the pinnae--Marsilea: the only cryptogam known to sleep--Concluding remarks and summary--Nyctitropism consists of modified circumnutation, regulated by the alternations of light and darkness--Shape of first true leaves.

Brassica oleracea, circumnutation of the radicle, of the arched hypocotyl whilst still buried beneath the ground, whilst rising above the ground and straightening itself, and when erect--Circumnutation of the cotyledons--Rate of movement--Analogous observations on various organs in species of Githago, Gossypium, Oxalis, Tropaeolum, Citrus, Aesculus, of several Leguminous and Cucurbitaceous genera, Opuntia, Helianthus, Primula, Cyclamen, Stapelia, Cerinthe, Nolana, Solanum, Beta, Ricinus, Quercus, Corylus, Pinus, Cycas, Canna, Allium, Asparagus, Phalaris, Zea, Avena, Nephrodium, and Selaginella.

It is a rule of wide generality, that whenever there is any difference in the degree of exposure to radiation between the upper and the lower surfaces of leaves and leaflets, it is the upper which is the least exposed, as may be seen in Lotus, Cytisus, Trifolium, and other genera.

In these two genera the elaters are attached to a sterile group of cells projecting into the upper end of the capsule, and on dehiscence remain connected with the tips of the valves.

As for the differentia being derived from the same genus as themselves, namely, Quality, and from no other genus, if we proceed on the principle that virtue is bound up with pleasure, vice with lust, virtue again with the acquisition of food, vice with idle extravagance, and accept these definitions as satisfactory, then clearly we have, here too, differentiae which are not qualities.

It remains to decide whether there can be any differentia derived from the genus to which the differentiated thing belongs, or whether it must of necessity belong to another genus?

Surely not: the differentiae must come from outside the genus differentiated: they must be differentiae of Being proper, but cannot be identical with it.
