anthers and stigma, but the styles diverge in a different direction from the stamens, and only their tip is stigmatic. L. micrantha, which is a very abundant plant in the dense bush bordering the West Coast sounds, is also furnished with pure white, delicate, hermaphrodite flowers. These have no scent, nor have I been able to detect any honey, and they are probably self-fertile, though occasionally visited by insects. Nat. Ord. Naiadeæ. The only species of the order which I have looked into is the ubiquitous Potamogeton natans. According to Delpino, quoted by Sir J. Lubbock,* “British Wild Flowers,” p. 159. this plant is proterogynous. I could not distinguish this peculiarity as being very well marked. The flowers are hermaphrodite, and probably can fertilize themselves; but they are also anemophilous, and produce a quantity of light powdery pollen, which is easily shaken out of the anthers. Triglochin, which also has one species in New Zealand, T. triandrum, is stated by Axell† Loc. cit., p. 161. to be proterogynous. I have not observed this plant carefully. Nat. Ord. Liliaceæ. Callixene parviflora, a beautiful little snowdrop-like plant, is common in the woods of the West Coast, the Bluff, and Stewart Island. I have not been able to notice any contrivance to secure cross-fertilization, and, with the exception of the prominent colour, the flowers have no great attractiveness to insects, being destitute of scent and honey. Cordyline australis—the common cabbage-tree—produces great massive panicles containing thousands of whitish flowers. These are hermaphrodite, but are evidently greatly dependent on insects. They are powerfully fragrant, and secrete a good deal of honey. I have seen them surrounded by great numbers of insects, chiefly Diptera, which, on bright sunny days, swarmed on them in hundreds. Astelia—which is usually separated into a distinct order, Asteliœ—is characterized among other things by its polygamo-diœcious flowers. A. nervosa is the only common species in this part of Otago, and is unique in its fertilization, for its flowers are very inconspicuous owing to their colour and are produced quite among the large foliage leaves, while lastly the plants themselves grow in the bush. Its habitat debars it from being wind-fertilized, the plants usually occurring in sheltered parts of the bush, where even a strong wind is little felt. The flowers are completely diœcious in function, but hermaphrodite in structure, though always more or less imperfect. The panicles of male flowers are much more lax and prominent than those of the female flowers, and are lighter and more con-
