No. 3 Shou-Biao Zhou, Xin Hong, Zhong-Lin Li & Fang Wen： Primulina diffusa (Gesneriaceae), a new species endemic to the karst limestone area in southwestern Guangxi, China
Annual Botanical Fennici 51: 212–216.

ABSTRACT

Primulina diffusa Xin Hong, Fang Wen & S.B. Zhou (Gesneriaceae), a new species growing in rocky crevices at the foot of a limestone hill near the Sino-Vietnamese border in southwestern Guangxi, China, is described and illustrated. It is morphologically similar to P. hochiensis and P. hochiensis var. rosulata, but can be distinguished by having single-flowered cymes; short peduncle (1–1.5 cm long); narrowly elliptical to subulate bracts, 2–2.5 × ca. 0.6 mm; 1–2 cm long pedicel; calyx lobes that are densely puberulent on both sides; and filaments that are geniculate near the middle.

No. 5  Fang Wen, Yi-Gang Wei & Hui-Zhen Lü： Primulina carinata (Gesneriaceae), a new species from Guangxi, China
NOVON 23:381–384.

ABSTRACT

Primulina carinata Y.G. Wei, F. Wen & H.Z. Lü (Gesneriaceae) is described and illustrated as a new species endemic to Guangxi, China. It is similar to P. parvifolia (W.T. Wang) Yin Z. Wang & J. M. Li, but can be distinguished by its lack of stolons, by its longer peduncle 12–20 cm or more (vs 5.3–5.6 cm in P. parvifolia), by the longer pedicels 10–12mm(vs. ca. 8 mm), by the ventral surface of the corolla tube longitudinally constricted, forming a keel(vs. the upper portion of corolla tube swollen, forming an elevated ridge), by the staminal sparsely glandular puberulent (vs. glabrous) ,and by filaments three staminodes (vs. two), with the lateral two at different lengths, ca. 4 mm and ca. 2mm (vs. the staminal pair at equal length,ca. 5 mm).

No. 6 Michael Möller , Wen-Hong Chen, Yu-Min Shui, H. Atkins &  D.J. Middleton： A new genus of Gesneriaceae in China and the transfer of Briggsia species to other genera
Gardens’ Bulletin Singapore 66(2): 195–205.

ABSTRACTSince the transfer of several species of Briggsia to Oreocharis, including the type species Briggsia longifolia, the remaining 16 species of Briggsia have been in taxonomic limbo. We address this unsatisfactory situation by transferring 10 further species into Oreocharis on morphological grounds and by raising a new genus, with two species, based on previously published molecular data and their morphological distinction from other genera. This leaves only four species for which, at present, no satisfactory solution is available but, for pragmatic reasons until further research can be done, we place them in Loxostigma to which they are morphologically most similar and in which one already has a combination. Several names are lectotypified.

Glabrella Mich. Möller & W.H.Chen, gen. nov.Differs from other Chinese genera of Gesneriaceae by the combination of indistinct short stem, 5–6 cm long; glabrous petiole and leaf blade, leaf base cuneate or narrowly peltate; fertile stamens 4, cohering in pairs at apex; capsule straight in relation to the pedicel, not twisted; and seeds unappendaged.

TYPE: Glabrella mihieri (Franch.) Mich. Möller & W.H.Chen (FIGURE 1)

Distribution. Two species, endemic to China.
Etymology. After the distinctly hairless leaves.

No. 7  Xin Hong, Ou-Wen Wang, Shou-Biao Zhou & Fang Wen：Primulina argentea (Gesneriaceae), a new species endemic to a karst cave in N Guangdong,  S China
Willdenowia 44: 377–383.

ABSTRACT

Primulina argentea Xin Hong, F. Wen & S. B. Zhou, sp. nov. (Gesneriaceae) is and illustrated from N Guangdong Province, S China. It is morphologically close to P. fengshanensis F. Wen & Yue Wang and P. orthandra (W.T. Wang) Mich. Möller & A. Weber, but is differentiated from its  congeners by several characters of the shape, texture and indumentum of the leaf blade and bracts, length of pedicels, size of calyx lobes, colour of corolla, indumentum of staminodes, etc. A description of P. argentea together with illustrations, distribution map, habitat description and a diagnostic comparative table with P. fengshanensis and P. orthandra are presented.

No. 8  Fang Wen, Yi-Gang Wei & Hui-Zhen Lü：Primulina glandaceistriata (Gesneriaceae), a new species from Guangxi, China
Phytotaxa 188 (1): 049–054.

ABSTRACT

Primulina glandaceistriata X.X. Zhu, F. Wen & H. Sun (Gesneriaceae) from Lingchuan County, Guangxi, is illustrated and described as a new species. It is morphologically close to P. dryas and P. beiliuensis, but can be easily distinguished by its leaf blades oval, ovate or nearly rounded, and both leaf surfaces being sparsely purple strigulose and the hairs with a papillose base; shorter peduncle 7.5–9.5 cm long that is densely erectly purple pilose; bracts inside densely erectly purple pilose; corolla pale purple to purple, inner surface glabrous and with sparse purple spots and two obviously brown stripes, and the outer surface piloglandulose; staminodes longer, ca. 7.5 mm long. The conservation status of this new species was assessed as “Critically Endangered” (CR).
