some other plants, is illustrated in Sir J. Lubbock's work already referred to, at p. 114, to which the reader is referred for details. I have observed it in the following New Zealand Composites: Olearia ilicifolia and O. nitida, Celmisia longifolia, Lagenophora forsteri, Cotula coronopifolia (though not so decidedly as in the other species named), Cassinia fulvida, Senesio lautus and S. rotundifolius, and in Microseris forsteri. It is probably the rule in all the bright-flowered species. Of the genus Olearia, probably all are very attractive to insects—O. nitida, O. dentata, and O. ilicifolia, have their flowers arranged in large conspicuous corymbs, and are sweet-scented. I have not seen honey in them. O virgata has small sweet-scented heads, which are much less conspicuous than the preceding, while O. hectori has its flowers most deliciously scented, like ripe peaches. Of the genus Celmisia, the larger flowered species examined—namely, C. coriacea and C. hectori, though very conspicuous, have no fragrance and very little honey. The same remark applies to C. sessiliflora, in which the individual heads, though small, are produced in such immense numbers as to render the cushion-like masses in which the plant grows extremely conspicuous. In C. longifolia the flower-heads are solitary, but are slightly fragrant, and the tubes of the disc-florets contain a little honey. In Vittadinia australis the flower-heads are also produced singly. They are not so conspicuous as the last-named, and, though slightly fragrant, are probably more commonly autogamous. The protrusion of the stigmas from the hermaphrodite florets of the disc is very slight, and they are frequently found smeared with the pollen of the same floret. The ray-florets, however, being pistillate only, require the visits of insects to bring pollen to them from other flowers. Lagenophora forsteri and its small variety L. petiolata have small but conspicuous scentless flowers. The genus Cotula I have hardly looked into. C. coronopifolia has very conspicuous yellow flower-heads, which are destitute of fragrance and produce little or no honey. The minuter flowered forms, as C. dioica, C. minor, etc., do not seem to possess any attractions for insects. The absolutely unisexual species are probably anemophilous. The flower-heads of Cassinia fulvida are very conspicuous by association, and are sweet-scented. Ozothamnus glomeratus has also sweet-scented florets, which are much less conspicuous than the last. Gnaphalium bellidioides and G. trinerve are very conspicuous, owing to the large pure white involucral leaves which surround the flower-heads. These perform the function of the ray-florets in other Composites, acting as lures
