Solanum pachyneurum O.E. Schulz in Urb., Symb. Antill. 6: 195. 1909

Type: Cuba. Guantánamo: Santiago, prope Monte Libanon [Monte Libano], 1843, J. Linden 1944 (lectotype, K [ K000196232 ], designated here; isolectotype, BM [BM000886751]).

Distribution. Endemic to eastern Cuba, in forests at about 700 m elevation.

Representative specimen. Cuba, Guantanamo, Herbario Flora de Cuba (HFC) 52625 (B).

Schulz (1909) cited three collections in his original description of Solanum pachyneurum – Wright 382, Eggers 5197 and Linden 1944. Wright 382, original material of both Solanum pachyneurum and S. pachyneurum var. glabrescens (a synonym of S. pachyneuroides , see above), consists of a series of mixed sheets of S. pachyneurum and S. pachyneuroides . It is not clear whether the two taxa occur sympatrically, or whether Wright assigned his numbers to plants collected after the fact, common practice at the time (and very likely). The latter case is suggested by the labeling of the sheet of Wright 382 at GH (see Fig. 4b ). The sheet that Schulz examined in B has been destroyed, and other sheets of Wright 382 are mostly of S. pachyneurum , but some are a mixture of S. pachyneurum and S. pachyneuroides (see above). For this reason, it is more sensible to choose one of the many other syntypes of S. pachyneurum as the lectotype to avoid confusion. A sheet of Linden 1944 was not found at B and is presumably destroyed, but well preserved duplicates have been located at BM and K. Neither the K nor the BM sheet has any locality data, but the sheet at K ( Fig. 4c ) is better preserved, has reproductive parts and has therefore been selected as the lectotype.
