The former is poor in Cruciferae, Caryophyllaceae, Umbelliferae, Primulaceae and Labiatae; but for the occurrence of Calluna in Newfoundland it would have no heaths.
The principal orders, arranged according to their numerical importance, are as follows: - Leguminosae,Rubiaceae, Orchidaceae, Compositae, Gramineae, Euphorbiaceae, Acanthaceae, Cyperaceae and Labiatae.
Compositae are comparatively rare; so also Gramineae and Cyperaceae are in some places deficient, and Labiatae, Leguminosae and ferns in others.
Such are Papilionaceous flowers, Violaceae, many Labiatae, Scrophulariaceae and others.
The orders most abundantly represented are the Compositae, Cruciferae, Labiatae, Caryophyllaceae and Scrophulariaceae.
At this time he based his classification, like Caesalpinus, chiefly upon the fruit, and he distinguished several natural groups,, such as the grasses, Labiatae, Umbelliferae and Papilionaceae.
On the drier and higher mountains of the interior of the chain, the forests become more open, and are spread less uniformly over the hill-sides, a luxuriant herbaceous vegetation appears, and the number of shrubby Leguminosae, such as Desmodium and Indigofera, increases, as well as Ranunculaceae, Rosaceae, Umbelliferae, Labiatae, Gramineae, Cyperaceae and other European genera.
The herbaceous vegetation does not differ greatly, generically, from that of the east, and many species of Primulaceae, Ranunculaceae, Cruciferae, Labiatae and Scrophulariaceae occur; balsams abound, also beautiful forms of Campanulaceae, Gentiana, Meconopsis, Saxifraga and many others.
A peculiar character is imparted to the vegetation of this province by the growth over large tracts of evergreen shrubs and large herbaceous plants belonging to the Cistineae and Labiatae.
So also in Labiatae, such as dead-nettle (Lamium), the different whorls of inflorescence are developed centripetally, while the florets of the verticillaster are centrifugal.
This mixed character presents difficulties in such cases as Labiatae, where the leaves, in place of retaining their ordinary form, become bracts, and thus might lead to the supposition of the whole series of flowers being one inflorescence.
When a flower can be divided by a single plane into two exactly similar parts, then it is said to be zygomorphic. Such flowers as Papilionaceae, Labiatae, are examples.
52); or along with the corolla, as in Ranunculus, and is deciduous; or it remains after flowering (persistent) as in Labiatae, Scrophulariaceae, and Boraginaceae; or its base only is persistent, as in Datura Stramonium.
The labiate corolla characterizes the natural order Labiatae.
The union is usually most complete at the base; but in Labiatae the styles are united throughout their length, and in Apocynaceae and Asclepiadaceae the stigmas only.
Amongst gamopetalous plants several of our largest living families, including Campanulaceae, Labiatae, Solanaceae and Primulaceae, are still missing; and of Boragineae, Scrophularineae, Gentianeae and Caprifoliaceae there are only faint and doubtful indications.
Among the land plants may be noted the blue anemone; the ranunculus along the road-sides, with a strong perfume of violets; the Malta heath, which flowers at all seasons; Cynomorium coccineum, the curious " Malta fungus," formerly so valued for medicinal purposes that a guard was set for its preservation under the rule of the Knights; the pheasant's-eye; three species of mallow and geranium; Oxalis cernua, a very troublesome imported weed; Lotus edulis; Scorpiurus subvillosa, wild and cultivated as forage; two species of the horseshoe-vetch; the opium poppy; the yellow and claret-coloured poppy; wild rose; Cartaegus azarolus, of which the fruit is delicious preserved; the ice-plant; squirting cucumber; many species of Umbelliferae; Labiatae, to which the spicy flavour of the honey (equal to that of Mt Hymettus) is ascribed; snapdragons; broom-rape; glass-wort; Salsola soda, which produces when burnt a considerable amount of alkali; there are fifteen species of orchids; the gladiolus and iris are also found; Urginia scilla, the medicinal squill, abounds with its large bulbous roots near the sea; seventeen species of sedges and seventy-seven grasses have been recorded.
In a pentamerous flower one sepal may be superior, as in the calyx of Rosaceae and Labiatae; or it may be inferior, as in the calyx of Leguminosae (fig.
This occurs in Labiatae and Scrophulariaceae (fig.
