Comparative morphology and anatomy of Backebergia militaris (Echinocereeae–Cactaceae) cephalium [PDF]

Plant Systematics and Evolution, 2015
The morphology and anatomy of the Backebergia militaris cephalium is characterized in comparison with its vegetative branch and with apical and lateral cephalia of other species. Our working hypothesis was that the B. militaris cephalium is more similar to the apical or lateral cephalia of other taxa than to its own vegetative branch.

Identification of New Cactus Alkaloids in Backebergia militaris by Tandem Mass Spectrometry

Journal of Natural Products, 1984
Tandem mass spectrometry, applied to simple extracts of Backebergia militaris, indicated the presence of a number of new alkaloids, including fully aromatic oxygenated isoquinolines, their di- and tetra-hydro analogs, and beta-phenethylamines. These conclusions were supported by separation using radial tlc and comparison with authentic compounds ...
