Figure 3.6. View of a longitudinal section through the flower of P. coriacea
demonstrating method of measurement. a. Length of androgynophore. b.
Width of androgynophore. c. Width of limen floor. d. Height of limen. e. Width
of limen. f. Height of nectary. g. Length of ovary. h. Width of ovary. Note that
the operculum is straightened and (shaded) measured from base to tip.
Seventy quantitative characters were initially evaluated for the Neighbor
Joining analysis of the P. suberosa complex, but 25 were discarded due to lack
of variability or lack of non-ambiguous gaps in the pattern of variation, making
state delimitations difficult (see for example Fig. 3.7). Of the 45 remaining, six
show no overlap in the range of variation of their states (see for example Fig.
3.8). The remaining 39 quantitative characters were utilized even though they
exhibit some arbitrariness in state delimitation (see for example Fig. 3.9).
