FIGURE 3. The continuous variation of leaf shape in one population.
Figure 3 from: Dickinson T, Christensen K, Zarrei M, Kuzmina M, Talent N, Lin C (2014) Crataegus ×ninae-celottiae and C. ×cogswellii (Rosaceae, Maleae), two spontaneously formed intersectional nothospecies. PhytoKeys 36: 1-26. https://doi.org/10.3897/phytokeys.36.6784
Figure 3 - A Neighbor-joining tree calculated by BOLD for ITS2 DNA barcode sequences amplified directly from genomic DNA (labels include corresponding collector and GenBank number; see dx.doi.org/10.5883/DS-CRATMONO and Table 1 for details). Dashed lines indicate the sectional affinity of the sequences B The corresponding Neighbor-Net network for the cloned ITS2 sequences has three branches representing: (a) ribotypes from individuals of Crataegus monogyna, and from its hybrids with both Crataegus suksdorfii and Crataegus punctata; (b) ribotypes from individuals of Crataegus suksdorfii and Crataegus ×cogswellii; and (c) ribotypes from individuals of Crataegus punctata and Crataegus ×ninae-celottiae (Table 3). The numbers shown are the % bootstrap support for each of the three branches.

Figure 4 - Geographic distribution of Crataegus ×ninae-celottiae K.I. Chr. & T.A. Dickinson nothosp. nov. and Crataegus monogyna in Ontario. Filled square, holotype of Crataegus ×ninae-celottiae; Crosses, TRT specimens of Crataegus ×ninae-celottiae; asterisks, Crataegus ×ninae-celottiae specimens cited by Wells and Phipps (1989); stars, specimens of Crataegus monogyna in MT, MTMG, QFA, TRT, and UBC. Crataegus punctata occurs throughout the region depicted (Phipps and Muniyamma 1980; this paper also maps additional records for Crataegus monogyna).

Filled square, holotype of Crataegus ×cogswellii; crosses, TRT specimens of Crataegus ×cogswellii; circles, diploid Crataegus suksdorfii; stars, Crataegus monogyna (specimens in OSC, TRT, UBC, and WTU).

Figure 7 - Holotype of Crataegus ×cogswellii K.I. Chr. & T.A. Dickinson nothosp. nov. (♀Crataegus suksdorfii × ♂Crataegus monogyna): TRT00002574, U.S.A., Oregon, Linn Co., Cogswell-Foster Preserve, 44.333082°N, 123.122547°W, 3 Sep 2009, Dickinson & Dickinson 2009-40.
Figure 2 from: Dickinson T, Christensen K, Zarrei M, Kuzmina M, Talent N, Lin C (2014) Crataegus ×ninae-celottiae and C. ×cogswellii (Rosaceae, Maleae), two spontaneously formed intersectional nothospecies. PhytoKeys 36: 1-26. https://doi.org/10.3897/phytokeys.36.6784
Figure 2 - A Principal components analysis of 39 Fourier amplitudes for 86 subterminal short shoot leaves from 20 Crataegus individuals at the Cogswell-Foster Preserve in Linn Co., Oregon (one Crataegus suksdorfii (s), seven Crataegus monogyna (m), and 12 putative hybrids (h), Crataegus ×cogswellii). Leaf outlines illustrate the shape contrasts responsible for the ordination: in grey, six subterminal leaves from short shoots of a single individual (OR1–8) B Principal components analysis of 39 Fourier amplitudes averaged for leaves sampled regardless of position on short shoots of 64 herbarium specimens from the Cogswell-Foster Preserve and (circled points) other locations in the Pacific Northwest (Table 1). In both A and B the two PCA axes shown are significant according to the broken-stick criterion (Frontier 1976). In B arrowed point 1 represents the single individual of Crataegus suksdorfii for which individual leaves are represented in A, while arrowed point 2 represents the averaged data for the six leaves of Crataegus monogyna shown in grey in A.
Figure 1 from: Dickinson T, Christensen K, Zarrei M, Kuzmina M, Talent N, Lin C (2014) Crataegus ×ninae-celottiae and C. ×cogswellii (Rosaceae, Maleae), two spontaneously formed intersectional nothospecies. PhytoKeys 36: 1-26. https://doi.org/10.3897/phytokeys.36.6784
Figure 1 - Principal components analysis biplot for five morphometric descriptors averaged for each of 41 Crataegus herbarium specimens from the Cogswell-Foster Preserve and other locations in the Pacific Northwest (Crataegus suksdorfii (s), Crataegus monogyna (m), and the putative hybrid, Crataegus ×cogswellii (h)): relX, leaf length above the widest point, scaled by the width; relZ, leaf length below the widest point, scaled by the width; invDI, inverse dissection index = 2(Aπ)1/2/P, where A is the leaf area and P is the leaf perimeter; STAM, number of stamens per flower; STYL, number of styles per flower. Both axes shown account for significant portions of the total variance according to the broken-stick criterion (Frontier 1976).
