Text Appearing Before Image:
ke those of Tulips (Tulipa), have a small depression which secretephoney on the broad thickened base of the filament opposite the corolla. In thfwidely-distributed Meadow Saflron {Colchicum autumnale) there is an orange-coloured honey-secreting body on the stamens just above the place of unionwith the violet leaves of the perianth, and the honey there formed fills a channelwhich traverses the adjoining perianth-leaf. The same thing occurs in otherSafirons and also in the genus Trillium. In Geraniaceous plants, especially inErodium and Geranium, a wart-shaped, sometimes hollow, nectary arises onthe base of each of the five inner stamen-filaments on the side directed towardsthe sepals. The nectaries at the base of the thread-like filaments of manyCaryophyllacesB exhibit an immense variety of form. Sometimes all the stamensof a flower are a little thickened at their root, and secrete honey from a yellowtissue opposite the ovary (e.g. in TelepJiium. Imperati), or a pair of honey-secreting

Very often thenectaries of adjacent stamens, in the flowers of the above-mentioned plants, fusetogether into a ring, the fusion being only just indicated in the Geraniaceaj, butmore decidedly in many Caryophyllace^e (e.g. in Spergvla), and still more amongstLinaceous and Caryophyllaceous plants (Linum, Gypsophila, Dianihus, Lychnis).In the flowers of most Papilionacese the stamens form the nectar. Nine stamensare fused into a tube in which the ovary is inclosed. This ovary is at the baseof the flower narrowed into a stalk, while the tube, onthe other hand,
