The combined plastid matrix consisted of 41 accessions corresponding
to 32 Oxalis species, and it comprised 2661 aligned sites
among which 2039 were constant, 266 uninformative and
356 parsimony-informative characters (13.38%). The aligned matrix
for nrITS sequences comprised 46 accessions from 32 Oxalis
taxa. The data matrix had 765 characters, of which 335 were constant,
128 uninformative and 302 parsimony-informative (39.48%).
Parsimony analyses of the plastid and nrITS datasets yielded topologies
with 845 steps (consistency index [CI] = 0.844, retention index
[RI] = 0.941) and 1095 steps (consistency index [CI] = 0.646,
retention index [RI] = 0.819), respectively. The resulting topologies
from the phylogenetic analyses were very similar to each other
(Fig. 1), although there was incongruence in the placement of O.
