Discussion:
This new species is without close allies, being characterized by its very small flowers with urceolate corollas. ;,In foliage it may most nearly suggest D. humboldtii (Kl.) Nied. and D. pampii (described above), but the size and shape of the corolla and the minute anthers of D. micranthum make detailed comparisons superfluous.
