Single shortest unrooted gene tree (Length 702 steps; consistency
index 0.6677) resulting from maximum parsimony analyses of published Internal
Transcribed Spacer One sequences. Sequences originally published in Schroth
et al. (2002) are indicated by their original three or four letter identifier;
all other sequences were originally published in Dawson and Jacobs (2001).
Bootstrap values > 50% are shown above each branch. The morphologies of
taxa in bold font (sp. 1, sp. 3, sp. 4, sp.6) are described by Dawson
