or flags of invitation to honey-loving insects. These flowers are also sweet-scented. The genus Erechtites has inconspicuous greenish flower-heads, which never expand much. They have no scent, and no honey, and are probably self-fertilized. The genus Senecio exhibits a great diversity in its flowers. S. lautus has yellowish, but by no means conspicuous flowers. These are scentless, but contain a little honey, and, as has been already remarked, are proterandrous. S. lagopus and S. bellidioides (probably two extreme forms of the same variable species), and the beautiful S. lyalli, have very conspicuous flowers, which are also scentless, and produce very little honey. S. rotundifolius, which grows so abundantly round the coasts and in the bush of Stewart Island and the West Coast Sounds, has comparatively inconspicuous flowers, but these are of an overpowering fragrance, and the tubes of the florets almost overflow with honey. Lastly, Microseris forsteri has solitary flower-heads destitute of scent, and with very little honey, but they are bright yellow, very conspicuous, and proterandrous. Nat. Ord. Stylidieæ. The flowers of this order are characterized inter alia by being gynandrous, i.e. having their style and stamens united into a column. Instead of aiding in self-fertilization, as might at first be supposed, this arrangement more commonly prevents it. The order is represented by three genera in New Zealand. Phyllachne (Forstera) sedifolia has extremely variable flowers as to size, those which grow on the hills near Dunedin being seldom more than a fourth of an inch in diameter, while some gathered by me on Frazer Peaks, Stewart Island, were over three-fourths of an inch, and furnished with a very beautiful dark-purple eye. All I have gathered have been hermaphrodite, but according to Hooker they are sometimes unisexual. These flowers are scentless, but so strongly proterandrous as to be practically diœcious. The two stamens shed all their pollen, and wither completely, before the stigmas commence to expand and recurve. The flowers are furnished with two epigynous glands, whose function I have not made out; it may be to secrete honey, of which the flowers contain a little. They are manifestly entomophilous. Stylidium subulatum is a very doubtful member of this genus. Its column is short and straight, and in no way irritable, whereas one of the characteristics of the genus is a bent, irritable column which springs up with considerable force on a touch, and throws the pollen out of the
