Bentham erroneously described the corolla shape as “fere campanulata,” since an examination of the type collection shows a broadly infundibuliform corolla 8 mm long with a tube 6 mm long and 4-4.5 mm wide at the summit, and the other collections of this taxon repeatedly have a subcylindric to elongate infundibuliform shape.
As indicated above under the discussion of C. naiguatensis Steyerm., Wernham's description of C. erubescens applies mainly to the two specimens cited by him (Martin s n and Herb. Rudge), and I have selected the Martin specimen as lectotype (K) for that binomial, synonymous with C. nitida var nitida. The fruiting specimen at K of Martin s n, indicated by Sandwith as “isosyntype coll.,” is well matched in its foliage and length of the infructescence by Steyermark 88584. It is to be noted that a similar development of granular excrescences or granular-pulverulence is prevalent over the surface of the calyx tube and hypanthium on the Martin specimens at K, the Schomburgk 1055 collection at K, and material collected subsequently here referred to C. nitida var nitida.
