Description: [syn. Datura Gardneri Hook.f.] Shrub or small tree, 6-15 feet, glabrous to minutely pubescent; leaves ovate to narrowly elliptic, entire; flowers large, 8-12 inches long, odding but not completely pendulous, calyx 2-5 toothed, slightly inflated, persistent and generally enclosing the fruit; corolla white, more campanulate than trumpet shaped, constricted for a short distance beyond the calyx, teeth 1.5 inches long or less, flaring but not recurved, anthers connivent; fruit fusiform, 4-6 inches long, somewhat rugose.
There are no herbarium collections of any species of this genus made from confirmed wild plants.
No botanist specialising in this genus has ever reported seeing wild plants of any species.
(Verbal) Reports by non-specialist botanists of the occurrence of ‘wild’ plants are either misidentifications (usually of Datura), or misinterpretation of remnants or localised escapes from cultivation, usually along creeks and occurring by vegetative propagation from stem fragments. In all such instances investigated in Ecuador and Colombia, the plants are of the anthropogenic hybrid Brugmansia x candida (Hay et al. 2012: 172-177). It is quite clear that such instances do not represent self-sustaining sexually reproducing populations.3
The complete lack of evidence of fruit dispersal or spontaneous seedlings, combined with the presence of large numbers of fruits containing viable seed, suggests their dispersers are extinct. Hence, all the species should best be regarded as extinct in the wild.3
