Pentachondra pumila is somewhat similarly furnished with a densely-bearded corolla-tube, and is probably fertilized in the same manner. In the summer of 1876 I had a plant of this in flower under glass, and, though it produced numerous blossoms, no fruit resulted. In each case, after the gradual withering of the corolla, it was found that the ovary had shrivelled also. Dracophyllum longifolium has very conspicuous fragrant clusters of flowers. These contain a great deal of honey, and are therefore no doubt visited by insects. They are hermaphrodite, but I have not seen any special contrivance to render self-fertilization impossible. Birds occasionally visit the flowers. Nat. Ord. Myrsineæ. The only New Zealand genus is Myrsine, of which two species—M. urvillei and M. divaricata—are common in the neighbourhood of Dunedin. I have examined the flowers of the former, and find them mostly diœcious. The male flowers have an imperfect ovary, while the female flowers have stamens with small anthers, which, however, contain no pollen. This is morphologically so slight a remove from hermaphroditism that I think the latter must frequently occur. In all cases I have noticed they have, however, been functionally diœcious. The flowers are produced in great numbers, are small and rather inconspicuous, have no scent and no honey, while their pollen is light and very incoherent, all of which considerations lead me to consider them as always anemophilous. Nat. Ord. Apocyneæ. The only plant of this order found here—Parsonia albiflora—has puzzled me a good deal. It is a straggliug climber producing panicles of pendulous white flowers. These have a funnel-shaped corolla, the lobes of which bend back. The stamens are syngenesious—that is, their anthers are united together. These anthers are arrow-shaped, with very acute apices, and when joined together they form a sharply-pointed conical cap (not unlike some forms of metal drills) which fits closely on the summit of the stigma. Of each anther, one cell only produces pollen, which seems to me to be always applied directly on the stigma. In fact, this introrse dehiscence of the anther, and the application of the pollen on the stigma, is given by Le Maout and Decaisne* * “Descriptive and AnalyticalBotany,” by Le Maout and Decaisne, p. 550. Edited by Sir J. D. Hooker. (Longmans and Co.) as a characteristic of the order. At first sight this would make us at once conclude that the flowers were self-fertile, in which case insect-aid would not be absolutely necessary. But what appears a still greater difficulty is that the pollen is all contained inside a cap, from which I have not seen it shed, and which does not readily open from any side. Yet the flowersare usually fragrant, and contain a large quantity of honey. I am inclined to think that, had I examined the flower at different stages of
