          Abstract

          Two new species of Gesneriaceae , Paraboea myriantha sp. nov. and P. brevipedunculata sp. nov. are described and illustrated with photos. They grow in the Caryota obtusa forests from Yunnan Province of China. P. myriantha is closely related to P. glutinosa (Hand.-Mazz.) K.Y.Pan, but differs mainly in corolla outside glandular-puberulent, adaxial corolla lobes semicordate, corolla tube obliquely campanulate, and filaments glandular-puberulent. P. brevipedunculata is closely related to P. crassifolia (Hemsley) B. L. Burtt, but different mainly in simple dichasia with 1 and 2 flowers, peduncles 0.5–2 cm long and capsules slightly twisted. The geographical relationship between the two new species and their similar species has been discussed.

              A REVISION OF PARABOEA (GESNERIACEAE)

              The genus Paraboea Ridl. ( Gesneriaceae ) is revised. It is found in Bangladesh, Bhutan, Burma, Cambodia, southern China, India (Assam), Indonesia (Sumatra, Java, Borneo, Sulawesi), Laos, Malaysia (Peninsular and Borneo), Philippines, Thailand and Vietnam, mostly from limestone habitats. Eighty-nine species and five varieties are recognised. Four new species and one new variety are described: Paraboea apiensis Z.R.Xu, Paraboea argentea Z.R.Xu, Paraboea graniticola Z.R.Xu, Paraboea paraprimuloides Z.R.Xu and Paraboea harroviana var. ovata Z.R.Xu. In addition two taxa are highlighted as possible new species but are not described here due to insufficient material. The treatment includes one new combination for a species, Paraboea harroviana (Craib) Z.R.Xu, one new combination for a variety, Paraboea schefferi var. ambigua (C.B.Clarke) Z.R.Xu, one new status for a variety, Paraboea rufescens var. tomentosa (Barnett) Z.R.Xu, and one new name, Paraboea primuloides Z.R.Xu. Fifty-one line drawings are included. A key is presented and all taxa are described. Preliminary conservation assessments are given.
