Corolla noted by Barter “deep orange sometimes red.” This species is so like 
L. elegans that T. Anderson has inscribed Barter, 3381, as LD. elegans, T. Anders., 
though it is typical Z. Barterit. The “bracts” in ZL. elegans are homologous with 
the floral leaves in ZL, Barteri, and similar to them; the inflorescence of L. elegans 
might be theoretically called a linear panicle, the cyme under each floral leaf being 
teduced to a single flower with 2 bracteoles.
