Two of these drops are in- dicated in Fig. 6. The presence of these drops has been observed from time to time for many years, and even Linnaeus saw them and knew that they were nec- tar. But no study of the glands which secrete this fluid appears to have been made, till , when they were briefly described by a Frenchman, M. Brong- niart. Notwithstanding this descrip- tion, even in the last year the glandular tissue has been wrongly described as disseminated in the ovary, by one of the highest authorities on the relations be- tween flowrers and insects. With a sharp razor the ovary may be cut from top to bottom in such a way that the section shall pass through the middle of a cell and the middle of the opposite partition. Such a section is shown, enlarged 11 diameters, in Fig. 7. The cell of the ovary is partly tilled by the ovules or young seeds (f), and a narrow pocket (d) is found extending down a short distance from the point where the drop of nectar was seen, into the tissue of the septum or partition. This is one of the nectar glands, and is a so-called septal gland of the ovary. A thin section across the ovary near its top, shows all three of the glands as very small crevices in the septal tissue. Such a section, at the point xy of Fig. 7, is shown in Fig. 8, where it is enlarged 17 diameters. The gland tissue, which differs very little from that surrounding it, is indicated by the figure 1. Septal glands similar to, though much larger than those of the hyacinth, are found in the ovaries of many lily-
