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.
