FIGURE 4 in Asarum chueyi (Aristolochiaceae), a new species from the foothills of the Blue Ridge Mountains of Tennessee and Virginia, USA
FIGURE 4. UPGMA phenogram of stamen filament characters and EFA shape descriptors of calyx tube shape of the flowers of A. contractum (red), A. chueyi (black), A. heterophyllum (green), and A. minus (pink).
FIGURE 5 in Asarum chueyi (Aristolochiaceae), a new species from the foothills of the Blue Ridge Mountains of Tennessee and Virginia, USA
FIGURE 5. Photographs of A. chueyi flowers from Tennessee (A–C) and Virginia (D and E) populations. Typical flower with one sepal removed (A, D), entire flower (B, E) and floral orifice (C). Note that the thecae have not dehisced in A. Scales are not constant between photographs, nor are flowers depicted at their true sizes.
FIGURE 3 in Asarum chueyi (Aristolochiaceae), a new species from the foothills of the Blue Ridge Mountains of Tennessee and Virginia, USA
FIGURE 3. Illustrations of A. chueyi showing A) a whole plant (prepared from the holotype; scale represents 6.5 cm), and B) a flower with a single sepal removed to reveal the reproductive column, C) a dissected sepal, and D) an entire flower (each prepared from field-preserved flowers from Tennessee and Virginia; scale represents 2.3 cm). Illustrations prepared by Ryan A. Folk.
FIGURE 2 in Asarum chueyi (Aristolochiaceae), a new species from the foothills of the Blue Ridge Mountains of Tennessee and Virginia, USA
FIGURE 2. Ordination represented by coordinates 1 and 2 resulting from Nonmetric Multidimensional Scaling of Elliptical Fourier shape descriptors of calyx tube shape of A. contractum (+), A. chueyi (circles), A. heterophyllum (triangles) and A. minus (squares). The biplot depicts the impact of stamen filament morphology on data point spread.
FIGURE 1 in Asarum chueyi (Aristolochiaceae), a new species from the foothills of the Blue Ridge Mountains of Tennessee and Virginia, USA
FIGURE 1. Example of an A. chueyi (1195) calyx tube silhouette, with the sepal lobes cropped, used for Elliptical Fourier Analysis. The proximal and distal portions of the flower are to the left and right, respectively.
FIGURE 2. A in Asarum rosei (Aristolochiaceae), a new species from the Blue Ridge Escarpment of North Carolina, USA
FIGURE 2. A) Gynostemium with extrorse thecae, broad stamen filaments, and well-developed style extensions. B) Calyx tube typical of the species. Note that the tube is broadest above its midpoint.
FIGURE 1. A in Asarum rosei (Aristolochiaceae), a new species from the Blue Ridge Escarpment of North Carolina, USA
FIGURE 1. A) Habit of mature A. rosei individual at anthesis. B) Flowers of A. rosei showcasing entirely white trichomes covering sepal lobes. Photographs taken by Mark Rose.
FIGURE 4. A in Asarum rosei (Aristolochiaceae), a new species from the Blue Ridge Escarpment of North Carolina, USA
FIGURE 4. A) Photograph depicting type locality and associate species. Photograph taken by Mark Rose. B) Leaf of A. rosei. Note the conspicuously crenulate margins.
FIGURE 3 in Asarum rosei (Aristolochiaceae), a new species from the Blue Ridge Escarpment of North Carolina, USA
FIGURE 3. White multicellular trichomes of sepal lobes. Note the transition to red trichomes that occurs in the background of the photograph, as the frame progresses into the calyx tube.
FIGURE 3 in Asarum koreanum (Aristolochiaceae), a new species from Korea
FIGURE 3. Morphological characteristics of Asarum koreanum. A. Habit; B. Rhizome; C. Leaf (adaxial); D. Leaf (abaxial); E. Cataphyll; F. Apical view of flower; G. Lateral view of flower; H. Pistil and stamen; I. Seed (Photographs: Hyosun Leem).

FIGURE 1. The difference in the density of the glandular trichomes on the adaxial surfaces of the calyx lobes between Asarum koreanum and Asarum sieboldii. A1–A2. A. sieboldii; B1–B2. A. koreanum. (Photographs: Hyosun Leem; modified from Leem & Oh 2019).
FIGURE 4 in Asarum ampulliflorum (Aristolochiaceae), a new species from Taiwan
FIGURE 4. Comparison of stigma and style morphology of Asarum ampulliflorum (A), A. asaroides (B), A. macranthum (C), and A. satsumense (D).
FIGURE 3. A in Asarum ampulliflorum (Aristolochiaceae), a new species from Taiwan
FIGURE 3. A histogram showing differences in the ratio of the perianth tube length to the diameter at the widest points of perianth tube and the ratio of the perianth tube length to limb-lobe length among Asarum ampulliflorum (am), A. asaroides (as), A. macranthum (ma), and A. satsumense (sa). The lines in the plot indicated the range of each character from each species.
