exceedingly variable, sometimes all cordate and the upper small ones clasping the 
stem, sometimes all narrow with very few on the stem, the petiole in some 
specimens dilated at the base, and stem-clasping or shortly decurrent. Flowers 
sweet-scented, especially at night, of a pure white or greenish outside, in loose 
terminal racemes often branching into irregular panicles, and excedingly variable 
in size, on short or long pedicels. Bracts usually small and linear or none under 
the upper pedicels, but sometimes all larger and leafy. Calyx varying from 3 to 
G lines long, the lobes usually very narrow and as long as the tube. Corolla-tube 
slender or broad, varying from 4in. to 2in. in length, usually slightly swollen 
under the throat ; limb spreading Hat, from ^ to 1 in. diameter, the lobes short 
and broad, emarginate obtuse or almost acute, the 2 upper ones usually rather 
smaller than the others. Filaments adnate high up; anthers ovate or oblong, 
4 usually at the throat of the corolla, the fifth much lower down. Capsule ovate, 
slightly acuminate, rather shorter than the calyx-lobes. Seeds very small and

According to Ur T. L. Bancroft, an extract of this plant i- very poisonous, in every respec 1 
resembling the physiological action of Tobacco (N. Tahacum, Linn.) He state-, that it contains 
a small amount of nicotine. 
Var. parviflora . Corolla much under lin. long. Leaf -petioles sometimes auriculate, some- 
times not. Panicle large and loose. — The common form north and south. 
Var. lonyiflora. Corolla-tube at least 2in. long. Leaves various Amby Creek and other 
inland localities. 
From Mr. G. L. Debney, of Monkira, 1 have a specimen of a form intermediate between var - 
parviflora and var. longi flora, which appears to be a more robust, plant than either. It might 
bear the distinctive name of var. Dclmeyi : and I would advise it being used a< Ihe mother plant 
in obtaining a cross between it and some of the cultivated tobaccos.

Garden forms between the two species, 1’. ay ctiyini flora. Juss.. and 1‘. riolnrea, Lindl.. are 
often met with near towns as strays from garden culture.
