Figure 7 - Original material of Convolvulus binghamiae Greene, Santa Barbara, 1886, E.L. Greene s.n. (NDG [NDG-66275]). Flower buds with large clasping bracts typical of the Calystegia sepium complex are noteworthy (a), as is the solitary flower (b) with a broad calyx, broad corolla tube, and a smallish, but otherwise typical clasping bract for the Calystegia sepium complex (Image courtesy of Barbara Hellenthal at the Notre Dame Herbarium).

Figure 4 - Map of historical and recently discovered Calystegia felix occurrences in the Chino Basin. The circled E marks the plant discovered in 2011; normal circles are 2013 occurrences, the largest a cluster of three populations. The broken circle is the approximate location of Johnston's collection in 1917. The perimeter of the Chino artesian belt and "moist land" prior to 1904 is delineated by the thick black line. The street map was adapted from the City of Chino draft general plan EIR, July, 2010, and the artesian belt is based on Mendenhall (1907).

Figure 9 - Emergent Calystegia felix on crusted, moist, Chino silt loam, amongst urban landscaping. It is unknown if large groups of emergent plants such as these represent one to just a few clones, or many genotypes (Photo M. C. Provance, 2013).
Figure 3 from: Provance M, Sanders A (2013) Lucky morning glory, Calystegia felix (Convolvulaceae): a new species from Southern California, with notes on the historical ecology of the Chino ciénega belt. PhytoKeys 32: 1-26. https://doi.org/10.3897/phytokeys.32.6020
Figure 3 - Calystegia felix in bloom at the type locality, in a planter bed in Chino. This plant, discovered in 2011, is the only one we have seen that produces corollas with reddish-purple midpetaline stripes. Also, note the blushed sepals (Photo M. C. Provance, 2011).

Figure 1 - Calystegia felix Provance & A.C. Sanders, sp. nov. The holotype, A.C. Sanders & M.C. and T.A. Provance 40174 (UCR [UCR-246125]). The flowering branchlets are from a single ramet (Photo M. C. Provance, 2011).
Figure 3 from: Matern A, Drees C, Hardtle W, von Oheimb G, Assmann T (2011) Historical ecology meets conservation and evolutionary genetics: a secondary contact zone between Carabus violaceus (Coleoptera, Carabidae) populations inhabiting ancient and recent woodlands in north-western Germany. ZooKeys 100: 545-563. https://doi.org/10.3897/zookeys.100.1546
Figure 3 - Correlogram showing the result of spatial autocorrelation analysis at three allozyme loci. Genetic distances D (Nei 1972) are indicated for the population pairs of the respective distance classes (squares). Dashed lines show the 95% confidence interval (1000 permutations) under the null hypothesis of spatially random differentiation. Significant deviations from the mean are indicated by filled squares (p < 0.05).

Figure 4 - Maximum width of the aedeagus tip A and the quotient of maximum and minimum width of the aedeagus tip B are plotted for each population. Boxes display 25–75%- quartiles and bars indicate medians. Whiskers show the total range of values without outliers. Outliers are indicated as circles and extreme outliers as diamonds. Numbers of measured individuals per population are shown in brackets. Pie charts show frequencies of elytral sculpture classes "0" (white), "1" (grey), and "2" (black) in each population. Significant differences between populations are indicated by the lines marked with asterisks.

Figure 1 - Carabus violaceus populations studied and proportion of specimens with different elytron sculptures (pie charts). White sections indicate the frequencies of smooth elytra, black sections indicate the frequencies of more than three striae per elytron, and grey sections indicate the frequencies of intermediate phenotypes, i.e. class "1". Numbers next to the pie charts indicate population number followed by sample size in brackets. The location of the study area is indicated as a white square on the map of Germany. Woodlands in the study region northwest of the town of Bramsche according to TK 50 3512 Bramsche (Landesvermessungsamt Niedersachsen 1998) are presented as striped patches. Size and position of ancient woodlands (black patches) are taken from the map by LeCoq (1805). In this study, these are called "Börsteler Wald" (in the north) and "Gehn" (in the south). White patches within woodlands indicate openings. Hedges are not shown.
