difficult (see for example Fig. 3.10). Of the 33 remaining, 17 show no overlap in
the range of variation of their states (see for example Fig. 3.11). The remaining
16 quantitative characters were utilized even though they exhibit some overlap
between delimited states (see for example Fig. 3.12).
Seventy quantitative characters were initially evaluated for the cladistic
analysis of the supersection, but 31 were discarded due to lack of variability or
problems in delimiting character states (see for example Fig. 3.13). Of the 39
remaining, only one shows no overlap in the range of variation of its states (Fig.
3.52). The remaining 38 quantitative characters were utilized even though they
exhibit some overlap in the range of variation assigned to different character
states between taxa (Figs. 3.14-3.51). In all species descriptions (Chap. 8), the
flower diameters were mathematically determined: 2(sepal length) + hypanthium
diameter.
Distribution maps were produced in ArcView GIS Version 3.2 (Environmental
Systems Research Institute, Inc., Redlands, California, USA). Label data from
herbarium specimens were used to determine the latitudes and longitudes
employed in the construction of distribution maps. The gazetteer consulted for
localities in the United States was the Geographic Names Information System
(GNIS), developed by the U.S. Geological Survey (USGS) in cooperation with the
U.S. Board on Geographic Names (US BGN) (http://geonames.usgs.gov/). For
international localities, the primary gazetteer consulted was the Geographic
Names Database (http://gnpswww.nima.mil/geonames/GNS/index.jsp). The
Geographic Names Database is on the GEOnet Names Server (GNS), the official
