Nine other orders, Geraniaceae, Rhamnaceae, Rosaceae, Myrtaceae,
Primulaceae, Loganiaceae, Liliaceae, Thymelaceae, and Cucurbitaceae, have
six or seven species each; and among the more important orders which have
less than five species each are Ranunculaceae, Cruciferae, Vaccinacae,
Apocynaceae, Boraginaceae, Scrophulariaceae, Polygonaceae, Orchidaceae, and
Juncaceae. The most remarkable feature here is the great abundance of
Lobeliaceae, a character of the flora which is probably unique; while the
superiority of Labiatae to Leguminosae and the scarcity of Rosaceae and
Orchidaceae are also very unusual. Composites, as in most temperate floras,
stand at the head of the list, and it will be interesting to note the
affinities which they indicate. Omitting eleven species which are
cosmopolitan, and have no doubt entered with civilised man, there remain
nineteen genera and seventy species of Compositae in the islands. Sixty-one
of the species are peculiar, as are eight of the genera; while the genus
Lipochaeta with eleven species is only known elsewhere in the Galapagos,
where a single species occurs. We may therefore consider that nine out of
the nineteen genera of Hawaiian {325} Compositae are really confined to the
Archipelago. The relations of the peculiar genera and species are indicated
in the following table.[77]
