removal of aquilonia. To circumvent this problem, they might have split B. integrifolia 
into four species (corresponding to the four phenetic-geographic clusters), but they 
refrained because of the existence of intermediates between most of the clusters. Instead, 
they described the four forms as subspecies of B. integrifolia.

Fig. 2. Shortest tree (396 steps) for geographic forms of Daviesia tilicifolia (in plain font) and related 
species (in italics, preceded by 'D.'). Found using branch and bound' in PAUP 3.f.l (Swofford 
1990) from data in Table 3. Numbers on internodes indicate bootstrap values from 100 replicates. 
The tree is rooted using the outgroup D. vn/attiam. Note that D. ulicifolia is paraphyletic by 
inclusion of four other species.

Fig. 3. Cladogram of Banksin integrifolia comprising four subspecies (.integrifolia, monticola, compar 
and aquilonia) and its sister-group, comprising the species B. canei and B. saxicola, from Tliicle 
(1993b). Note that if aquilonia were segregated as a species, the remainder of B. integrifolia would 
be rendered paraphyletic.
