ID notes: L. asperulifolia is a very distinctive species, easily recognized vegetatively by its whorls (or opposite on smaller plants) of sessile, rounded-based, acuminate, bluish-green (to yellowish-green when shaded or otherwise stressed) leaves on an unbranched stem 0.5-1 m in height. Young or depauperate plants may produce only opposite leaves and no flowers. When stems are injured or subjected to herbivory, they produce branches below the damaged site.
