Lycianthes heteroclita
(Sendtn.) Bitter var.
gracilis
Bitter (1919: 496)
Type
(
lectotype
, designated here):—
PANAMA
.
Canal Zone
:
Railroad
relocation
between Gorgona and Gatun
,
10–50 m
,
Pittier 2281
(
US
No. 676535 [digital photo!], isolectotype
US
No. 676536 [not found])
.
Nomenclatural notes
:—
Bitter (1919)
cited three gatherings in the protologue:
Pittier 2281
,
Williams 818
,
Tonduz 14727,
and he cited the herbaria housing the specimens he examined (and sometimes the accession number). We were able to locate part of the original material that he examined at the herbaria G-BOIS and
US
:
Pittier 2281
(
US
No. 676535 [annotated by Bitter as
L. geminiflora
],
US
No. 676536 [not found at
US
]);
Williams 818
(
US
No. 678304 [not found at
US
]);
Tonduz 14727
(G-BOIS-00415144! [annotated by Bitter as
L. heteroclita
ssp.
coalescens
Bitter (1919: 496)
]. The original material pertaining to
L. heteroclita
var.
gracilis
is problematic in that part of it is missing and the
two specimens
that we were able to locate were annotated by Bitter with a different name. Despite having annotated the
US
specimen of
Pittier 2281
as
L. geminiflora
, the specimen label specifies the floral color (violet) mentioned in Bitter’s description of
L. heteroclita
var.
gracilis
which differs from that of
L. geminiflora
(white). Therefore the specimen of
Pittier 2281
at
US
(
US
No. 676535) is selected here as the
lectotype
for the name
L. heteroclita
var.
gracilis
.
Taxonomic notes
:—This variety of the widespread
L. heteroclita
was described from
Costa Rica
and
Panama
as a variant with purple, stellate corollas (as opposed to the more common white color found further north). This color variant is the only color variant known from
Costa Rica
and
Panama
and merits further study.
