Seite 163 - It succeeds well in the common garden soil, and will grow in rather a shady situation, where many plants that are more tender will not thrive. It is readily increased by dividing at the root, or by seeds, which ripen plentifully* Our drawing was taken from a plant at the Garden belonging to the Apothecaries' Company, at Chelsea, last Summer.
Seite 97 - A dose of thirty grains has been found not only to excite vomiting, but to produce headache, vertigo, and temporary blindness. The germination of this plant is very curious, and has been thus described by Mr. NUTTALL. " The seed does not appear to possess any thing like a proper cotyledon ; the embryo, formed in the exact posture of the growing plant (with the radicle downwards), differs not from it in any particular but that of size. In place of a cotyledon there is a sheathing stipule, similar...
Seite 97 - ... its functions ; this callus, or seminal tubercle, is roundish, and turbinate, nearly as large as a filbert nut, very solid, and carneous, possessing in a high degree the alliaceous foetor of the grown plant ; the mutual point of attachment subsisting betwixt this body and the embryon, is at first a minute and nearly central funiculus, which...
Seite 97 - ... of the grown plant ; the mutual point of attachment subsisting between this body and the embryo is, at first, a minute and nearly central funiculus, which enlarges and becomes more distinct during the progress of germination ; but what appears to be most singular with respect to it is the length of time that it continues attached to the growing plant, lying apparently inert at the base of the caudex for twelve, or even eighteen months.
Seite 120 - Stamina approximate aut coarctata (nee coalita) ad apicem dentium tori pentagoni 5 dentati inserta. Filamenta basi dilatata oblonga vel triangularia, antheras demissius gerentia; lobi antherarum basi divergentes ; stamina 2 anteriora dorso appendices varias nectariferas in calcar intrantes gerentia. Ovarium nunc superum, nunc basi toro concavo cinctum et ideo semiinferum.
Seite 97 - ... proper cotyledon; the embryo, formed in the exact posture of the growing plant (with the radicle downwards), differs not from it in any particular but that of size. In place of a cotyledon there is a sheathing stipule, similar to that which is ever after produced ; in fact, it is viviparous. The embryo is seated in a small umbilical or hemispherical depression, in the upper end of what may be called a vitellus rather than a perisperm, judging by its functions : this callus, or seminal tubercle,...
Seite 6 - S. alpina, in being altogether more robust ; in bearing more flowers on each scape ; the segments of which are larger, and spread more flatly open ; the termination of the filament beyond the anther, is simple and subulate, and the petioles are densely hairy. In S. alpina, the scape is few-flowered ; the flowers are more finely fringed, and bell-shaped ; the filament beyond the anthers terminates in a bifid point; the leaves are narrower, more entire, and the petioles smooth.
