Hemiboea guangdongensis comb. & stat. nov., a cryptic species segregated from H. subcapitata (Gesneriaceae) based on morphological and molecular data

The taxonomic problem of cryptic species has long been recognized. Hemiboea subcapitata C. B. Clarke is a widespread and morphologically diverse species including two varieties, H. subcapitata var. subcapitata C. B. Clarke and H. subcapitata var. guangdongensis (Z. Y. Li) Z. Y. Li. However, genetic distance and molecular phylogenetic analyses based on nuclear ITS and four plastid DNA sequences (atpB‐rbcL, matK, rbcL, rpS16 intron) revealed that H. subcapitata var. guangdongensis is sister to H. subacaulis, and separated from H. subcapitata var. subcapitata, suggesting that it should be raised to the rank of an independent species as H. guangdongensis (Z. Y. Li) X. Q. Li & X. G. Xiang, comb. & stat. nov. Morphologically, the new species can be distinguished from H. subacaulis by its calyx 5‐sect from base, segments narrowly oblong‐lanceolate (versus calyx 5‐sect from base or 2‐lipped and adaxial lip 2‐lobed from below middle, segments ovate), peduncle glabrous (versus pubescent), and vermiform sclereids dispersed in leaf mesophyll (versus without sclereids).

Weber]较近,但叶宽卵形,叶基部近心形,叶缘具浅钝齿或呈浅波状齿,花冠紫色,花冠、花序梗、花梗、苞片及花萼均被紫色短柔毛而区别与后者; 分子生物学证据表明,在系统发育上与桂林小花苣苔[P. repanda var. guilinensis(W. T. Wang)Mich. Möller & A. Weber]近缘,但两者在形态学上相差较远。     

Paralagarosolen Y. G. Wei,a new genus of the Gesneriaceae from Guangxi,China

Wang) Yan Liu in having narrowly ovate to ovate leaf blade, leaf blade margin interrupted shallowly crenate, broadly lanceolate bracts, being 1–3‐flowered and possessing hairs on the upper part of the anthers where connected with the filaments; from P. shouchengensis (Z. Y. Li) Z. Y. Li in having narrowly ovate to ovate leaf blade, leaf blade margin interrupted shallowly crenate, broadly lanceolate bracts and possessing hairs on the upper part of the anthers where connected with the filaments.
