Discussion

The names Bryophyllum tubiflorum and Kalanchoë tubiflora are widely used in horticultural as well as botanical works, with K. delagoensis usually listed in synonymy as a nomen nudum. H. R. Toelken (1985) wrote that the three-word original diagnosis of K. delagoensis was enough to distinguish it from other species treated. R. W. Long and O. Lakela (1971) misidentified it as K. grandiflora A. Richards.

The subcylindric part of the leaf seems to be the petiole, bearing a greatly reduced blade with one to four pairs of teeth (P. Boiteau and L. Allorge-Boiteau 1995).

This prolific species is an aggressive weed, well established in southern Florida and coastal southern Texas. In Australia, where it is called “mother of millions,” it is a serious pest because it is highly poisonous to cattle (P. I. Forster 1996).
