Discussion:

Type. Izamal, Yucatan, Mexico, 1895, George F. Gaumer 589.

Although the type collection was described as having 4 corolla lobes, my dissection of the type specimen at the Missouri Botanical Garden Herbarium shows 5 corolla lobes present on all the corollas examined. Likewise, the original description gives the length of the corolla tube as 2.5 mm, whereas dissection of type material reveals a length of 3.5 mm when the corolla is dissected after boiling, and a total corolla length of 6 mm. Dissection of material from Colombia and Venezuela shows a corolla variation of 5-6 mm in length and so far as known, 5-lobed. Since the fruit was not known at the time of the original description, the following may be presented: fructibus globosis negris 8-11 × 8-11 mm glabris, seminibus 4-11. In the Venezuelan and Colombian specimens the seeds average 4-7, in the Curacao material eight are present, whereas in those from Tamaulipas (King 4504) as many as 10-11 are present, although only six are in the Tamaulipas collection of King 3788.
