See Bot. Zeititng, 1900, p. 234. 86 Sudden Appearance and Constancy. Another interesting^ constant variety is Chelidonuunma jus latipetahun. (Fig. 11), for the possession of whichI am indebted to Prof. J. W. >\Ioll in Groningen. Itdiffers from C. inajus in its petals which are so broadthat their edges overlap so that they form an unbroken.
