*Cestrum aurantiacum Lindley, Edwards's Bot. Reg. 30: misc. 71, no. 65 (1844); 31: t. 22 (1845)

T: Described from plants cultivated in Chiswick Gardens from seed said to be native to Chimalapa, Guatamala; n.v.

Occasionally cultivated as garden plant; now an uncommon weed in south-eastern Qld and coastal N.S.W. with one record from Mt Gambier in S.A.

Occurs in waste places mostly in urban areas.

Toxic to sheep and cattle.

Flowers are reported to have a citrus-like aroma at night.

There is variation in this species with respect to hair covering in the material in AD at least. In some specimens the calyces, pedicels and inner face of the corolla lobes are glabrous (Bates 30977), while in others they are clearly pubescent (Annett s.n.). As well as this the shape of the calyx lobes is also variable, with some specimens being more or less ribbed (Bates 30977); this specimen is also glabrous within the corolla tube except at the point of insertion of the stamens, whereas the other specimen is hairy within the tube proper and on the lower half of the filaments. 

There could be two species being confused here and more investigation of the specimens involved is required.
