Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . e said to be monadelphous ; as in the Lupine, &c. (Fig. 462) and united by theirfilaments into twosets, they aie diadel-phous, as in mostplants of the Pulsefamily, where ninestamens form one setand the tenth is soli-tary (Fig. 461); andin Dicentra (Fig. 369 - 371), where the six stamens are equally com-bined in two sets. When united or ar-ranged in three sets or parcels, they aresaid to be triadelphous, as in the com-mon St. Johnswort; or if in several,polyadelphous; as in Linden. Whenstamens are united by their anthers intoa tube or ring, they are said to be syn-genesious (Fig. 463, 464). This occursin the Avhole vast order of the five filaments are distinct;whereas in Lobelia, and also in theMelon and Gourd (Fig. 465, 466), boththe filaments and the anthers are united; that is, the stamens aremonadelphous as well as syngenesious. 519. As to insertion, stamens are hypogynous (466) when borneon the receptacle, that is, when not adnate to any other organ;. FIG. 461. Diadelphous stamens (9 and 1) of a Pea. 462. Monadelphous stamens of aLupine. FIG. 463. Five syngenesious stamens of a Composita. 464. The same, laid open. FIG. 465. Column of stamens, at once triadelphous and syngenesious, of the Gourd: thefloral envelopes cut away. 466. A cross-section of the united anthers, nearly the natural A sinuous anther of the Melon.
