discussion
The only known collection of the present species was
rushed to the dryer because
of its condition at the end of a day of
collecting.
This species has an unusual 5' motif
(TCTGACCTCAAATCA) for nrLSU. For the list of known
taxa in section Vaginatae having this motif, see
the techtab of A.
penetratrix.
Stephen Russell and Igor Safonov have called my
attention to the similarity of the nrITS sequences of
the present species and A. justicei. The
number of such sequences (one for A. sp-A03,
seven for A. justicei) make up a very limited
sample. While there is variability in the
seven justicei sequences including SNPs, the
character positions in which the two species differ
are positions in which the available justicei
sequences are invariant. Unfortunately, we have
no example of nrLSU for the present species. The
situation provides insufficient data to inform a
decision of whether the two possible taxa should be
treated as one.
