In the protologue, no
holotype
was indicated and the species was divided into two forms,
S. prattii
f.
striata
Koehne (1913: 468)
and
S. prattii
f.
laevis
Koehne (1913: 468)
and a single gathering,
Prat 234
and
Wilson 3006
, respectively, was attributed to the two, respectively. The two forms were not recognized by
Lu & Spongberg (2003)
. Since no
holotype
was designated for
S. prattii
in the protologue, both varietal names were validly published like Ex. 3 and 4 under Art. 26.2. According to the Art. 25.1, both
Prat 234
and
Wilson 3006
can be
lectotype
of the species. It is obvious that the specific epithet is in honor of Prat, the specimen collector, but it is however not automatically typified by
Prat 234
. Here
Prat 234
, the type of
S. prattii
f.
striata
, is designated as the
lectotype
of the name
S. pratii
.
