On the whole, it consists of local species of some widely distributed northern genera, such as Carex, Poa, Ranunculus, &c., with alpine types of strictly south temperate genera, characteristic of the separate localities.
Hygrophytes.Plants which are sub-evergreen or evergreen but it scierophyllous, and which live in moist soils; e.g., Lastraea lix-mas, Poa pratensis, Carex ovalis, Plantago lanceolala, and ihillaea Millefolium.
During spring, autumn, and winter in particular, the blue-grass (Poa compressa and Poa pratensis) spreads a mat, green, thick, fine and soft, over much of the country, and it is a good winter pasture; about the middle of June it blooms, and, owing to the hue of its seed vessels, gives the landscape a bluish hue.
Of the best hay and pasture grasses, Agropyrum Elymus, Stipa, Bromus, Agrostis, Calamagrostes and Poa, there are 59 species.
The pili grass (Heteropogon contortus) is also noxious, for its awns get badly entangled in the wool of sheep. The native manienie (Stenotaphrum americanum) and kukai (Panicum pruriens), however, are relished by stock and are found on all the inhabited islands; the Bermuda grass (Cynodon dactylon), a June grass (Poa annua), and Guinea grass (Panicum jumentorum) have also been successfully introduced.
