(BM).
There has long been confusion over the correct name for this species.
Dunal’s (1813)
re-naming of Jacquin’s
Aquartia aculeata
as
Solanum aquartia
was illegitimate, but the name was used for many years. By the time
Schulz (1909)
made the correct combination
Solanum aculeatum
, the name
Solanum aculeatum
St.
- Lag. had been validly (but illegitimately) published as a replacement for
Solanum aculeiger
Dunal
(now recognised as a synonym of the Brazilian species
S. thomasiifolium
Sendtn.
, see
Solanaceae Source
, http://www.solanaceaesource.org). The oldest available name for this species is
S. tetramerum
.
No specimen of
Aquartia aculeata
attributable to Jacquin has been found, despite intensive searches in many herbaria (principally BM, LINN and W) where such a sheet, if it had ever existed, might have been preserved. No original material was cited in the protologue (Jacquin, 1760), so any type selected must be a neotype. The illustration of
A. aculeata
in Jacquin’s first illustrated edition of the
Selectarum Stirpium Americanarum Historia
(Jaqcuin, 1763), a copper engraving taken from original drawings done by Jacquin in the field (see
Wiltshear, 1913
) is very accurate, and I have chosen it here as the neotype of the species (
Fig. 5c
).
Solanum inclusum
was described without specific collection or locality but said to be widespread across the Caribbean and in northern South America (
Grisebach, 1861
). Various subsequent authors have suggested that Grisebach’s
S. inclusum
included both
S. tetramerum
and
S. polygamum
. No specimens have been identified at GOET that can be directly linked to Grisebach’s naming of
S. inclusum
. In his Cuban catalogue
Grisebach (1866)
cited specimens as
S. inclusum
that are now identified as
S. tetramerum
(
Linden 1986
,
2000
). Specimens indicated as type material of
S. inclusum
in some herbaria (i.e.,
Wright 1350
in GH) are in fact
S. torvum
. Since
Grisebach (1861)
did not indicate any specimens or specific localities for his name, these sheets cannot be considered type material. I neotypify Grisebach’s
Solanum inclusum
here with the BM duplicate (
Fig. 5d
) of
Linden 1986
in order to stabilise usage (synonymy) of this ambiguous name.
No duplicates of
Ekman H.7289
, the type of
Solanum
miragonae
, are extant at B, and the only sheet of this collection encountered is at S, so this is the clear choice as the lectotype (
Fig. 6a
). It may be that the S sheet is the holotype, as
S. miragonae
was described in a Swedish journal along with other taxa whose types are in S, but as there is no evidence of this, I prefer to lectotypify the name here.
Solanum aculeatum
var.
fuertesii
was described using several collections:
Fuertes 384, 386
and
396
. Of these,
Fuertes 384
has been located in several herbaria, the NY duplicate is here selected as the lectotype (
Fig. 6b
). In describing
variety
luxurians
, with larger, more repand leaves, several syntypes were cited:
Ekman H.2318
,
Ekman H.6732, Ekman H.8548
,
Ekman H.9979
and
Ekman H.8773
. The duplicate of
Ekman H.9979
in S (
Fig. 6c
) has an annotation label in Schulz’s hand with the varietal name
luxurians
, and is the logical choice for a lectotype.
