Table 3. Conflicts between the tree and taxonomy annotations in LTP.

	Genus	Family
Singletons	1,206	79
Non-singletons	1,328	326
Pure taxa	898 (68%)	171 (52%)
Impure taxa	430 (32%)	155 (48%)
Pure leaves	273	295
Impure leaves	12,680	12,658

Notes:

LTP does not annotate ranks above genus.

Columns are: Singletons, the number of singleton taxa; Non-singletons, the number of non-singleton taxa; Pure taxa, the number of non-singleton taxa which are pure; Impure taxa, the number of non-singleton taxa which are impure; Pure leaves, the number of pure leaves, i.e., the number of leaves found under the LCA for exactly one taxon; Impure leaves, the number of leaves which are not pure.
