The former is poor in Cruciferae, Caryophyllaceae, Umbelliferae, Primulaceae and Labiatae; but for the occurrence of Calluna in Newfoundland it would have no heaths.
Compositae are comparatively rare; so also Gramineae and Cyperaceae are in some places deficient, and Labiatae, Leguminosae and ferns in others.
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.
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.
