Nomenclatural notes
:—
Donnell Smith (1909)
cited one gathering in the protologue:
von Tuerckheim
II 2060
with no herbarium specified. We traced several specimens in the herbaria
BM
, E, F, M,
NY
, and
US
belonging to the cited gathering:
Tuerckheim
II 2060
(
US
barcode 00624002),

barcode 000514916(

), E barcode E00190707, F barcode 0072757F, M barcode M-0171534,
NY
barcode 00007074,
US
barcode 00624001). These specimens completely agree with the protologue and with the current application of the name (
Gentry & Standley 1974
) and can be safely considered as original material (Art. 9.3. of the ICN,
McNeill
et al
. 2012
). One of the
von Tuerckheim
II 2060
specimens at
US
(
US
No. 1335153 [barcode 00624002]) is selected here as the
lectotype
for the name
Brachistus ceratocalycius
.
Taxonomic notes
:—
Lycianthes ceratocalycia
is an herb to shrub with purple, stellate corollas that occurs in southern
Mexico
and
Guatemala
.
It
was under-collected until quite recently and mainly known from the
type
specimens. One of its most distinctive characters is a rough, scurfy texture on the young branches formed by horizontal indentations
.
