Bayesian majority consensus tree of <i>Primula</i> based on the four DNA markers (ITS, <i>mat</i>K, <i>trn</i>L-F and <i>rps</i>16) with main diagnostic characters (inflorescence types and calyx shape) mapped on.

<p>Numbers before and after the slash on the branches are parsimony bootstrap values (≥ 50%) and Bayesian posterior probabilities (≥ 0.5), respectively.

The Bayesian consensus tree of <i>Lysimachia</i> based on four molecular markers (<i>rbc</i>L, <i>mat</i>K, <i>psb</i>A-<i>trn</i>H, and ITS).

<p>The Bayesian posterior probabilities are shown below the branches and Maximum Likelihood (ML) bootstrap values above. Clade A, B, and C indicate subg. <i>Lysimachia</i> sect. <i>Hypericoideae</i>, subg. <i>Palladia</i> + subg. <i>Heterostylandra</i>, and subg. <i>Idiophyton</i> respectively. The boxed taxa represent the new species. Vertical bars with labels on the right side represent the series of sect. <i>Hypericoideae</i> proposed by Chen & Hu [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132713#pone.0132713.ref008" target="_blank">8</a>].</p

<i>Lysimachia huangsangensis</i> (Primulaceae), a New Species from Hunan, China

<div><p>A new species, <i>Lysimachia huangsangensis</i> (Primulaceae), from Hunan, China is described and illustrated. The new species is closely related to <i>L</i>. <i>carinata</i> because of the crested calyx, but differs in the leaf blades that are ovate to elliptic and (3–)4.5–9 × 2–3.4 cm, 2–5-flowered racemes, and the calyx lobes that are ovate-lanceolate and 5–6 × 3–4 mm. The systematic placement and conservation status are also discussed.</p></div
