The other form of flower is much smaller, seldom exceeding five-eighths of an inch in length, pale green and pink in colour, and with very short stamens furnished with abortive anthers, which contain no pollen. These flowers, though hermaphrodite in structure, are pistillate in function, and may often be seen with their stigmas smeared with the blue pollen of the larger form. In the “Handbook of the N.Z. Flora,” p. 728, the length of the stamens has been taken as a character separating F. procumbens from the other two, the latter having the stamens as long as or longer than the calyx-lobes, and F. procumbens having them shorter. I have, however, repeatedly found true F. excorticata with both forms of flowers, and F. procumbens also with both, and this is one of my chief objections to admitting the validity of the three species. Both forms of flowers are scentless, but produce a large quantity of honey within the calyx-tube. They appear to be fertilized only by tuis and honey-birds. As in the case of the other plants frequented by these birds, viz., Clianthus, Sophora, and Metrosideros lucida, the Fuchsia flowers are pendulous, affording no resting place for insects, while the great quantity of honey secreted would drown any but a large form furnished with a long trunk. I believe that the dimorphism manifested by our Fuchsias is a modification tending in the direction of separation of the sexes, and which would ultimately lead to the production of diœcious plants. This is remarkable, as occurring in an order characterized among other marks by the hermaphroditism of its flowers. Probably the polygamy already noticed as occurring in Leptospermum scoparium among the Myrtaceæ is a further development of the same tendency. The genus Epilobium is credited in the “Handbook of the N.Z. Flora” with seventeen species (or, as they might more correctly be called, varieties of about ten or twelve tolerably distinct forms). It is one of those remarkable genera probably undergoing rapid modification and development at the present time, in which the variety of form is so great that it becomes impossible to define the species with any accuracy. The various forms range from minute-flowered like E. nummularifolium var. brevipes to the large handsome-flowered E. pallidiflorum. All are strictly hermaphrodite, and I have not been able to notice any very appreciable difference in time between the maturing of the stamens and pistil. They all seem to be self-fertilized, though the finer-flowered forms are probably largely aided and crossed by insects. I have grown E. nummularifolium and E pubens, and carefully isolated them under glasses when about to flower, so that all access of insects or of wind was prevented, and they have produced a vast number of
