The second analysis (Text-fig. 10) revealed four clus- ters (cutoff distance = ) with values less. OVW Text-figure 8.—Diagram showing two measurements made on bi- directional flabelloid colony forms: IVW. valley width, and OVW. corallum width. In addition to these two measurements, total number of septa per 5 mm (TNS-5) and number of major septa per 5 mm (NMS-5) were also counted. "Major septa" are septa that extend completely to the columella. than Because one of the four clusters was com- posed of only one specimen (CCD 2069), only three clusters (later identified as M. geisteri. M. grandis. and M. jiingi) were considered further, thereby yielding a total of five clusters among the flabelloid forms with bidirectional budding. Differences among the five clusters were examined using canonical discriminant analysis and Duncan's multiple comparisons tests comparing means for each variable. An initial discriminant analysis revealed that three of the 68 specimens (CCD 2186, 2073, 2069) were incor
