It is closely related to<em> S. benthamii</em> C.B.Clarke but differs in the leaf and culm surfaces, culm shape, the absence of wings at the leaf sheath, contraligule features, nutlet morphology and micromorphology, and leaf and culm anatomy. An emended section of the key to the species in the Flora of Thailand account of <em>Scleria</em> is provided.</p> Wipawan Kiaosanthie Wanwipha Chaisongkram Kamolhathai Wangwasit ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 2018-09-21 2018-09-21 46 2 113 122 10.20531/tfb.2018.46.2.01 Miscellaneous Cucurbit News V https://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/128698 <p>Two recently described species are transferred from <em>Zehneria</em> to <em>Pilogyne</em>, namely <em>Pilogyne</em><em> subcoriacea</em> (Y.D.Zhou &amp; Q.F.Wang) W.J.de Wilde &amp; Duyfjes and <em>Pilogyne longiflorum</em> (G.W.Hu &amp; Q.F.Wang) W.J.de Wilde &amp; Duyfjes. A new species from Thailand is described, <em>Sinobaijiania frondosa</em> W.J.de Wilde &amp; Duyfjes. For <em>Thladiantha angustifolia</em> W.J.de Wilde &amp; Duyfjes a range extension into China is noted.</p> Willem J.J.O. de Wilde Brigitta E.E.

It is compared with similar species from Thailand (<em>Brassaiopsis ciliata</em> Dunn and <em>B. griffithii</em> C.B.Clarke) and Peninsular Malaysia (<em>B. sumatrana</em> Ridl.). They are primarily distinguished by differences in inflorescence size and position and in details of the indumentum. Two names sometimes confused with the new species,<em> Panax palmatus</em> Roxb. and <em>Hedera polyacantha</em> Wall., are lectotypified and discussed in connection with <em>Brassaiopsis hainla</em> (Buch.-Ham. ex D.Don) Seem. in order to distinguish them from the new species.</p> Hans-Joachim Esser ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 2018-10-08 2018-10-08 46 2 129 133 10.20531/tfb.2018.46.2.03 Dendrobium chrysocrepis (Orchidaceae), a new record for Thailand https://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/105391 <p>In this paper we report the first confirmed find of<em> Dendrobium chrysocrepis</em> in Thailand. A morphological description, a line drawing and a colour plate are presented (all based on Thai material), whereas some background information on the globally rare species is provided.</p> Orporn Phueakkhlai Somran Suddee Trevor R.

Schindl. subsp. <em>prainii</em> (Collett &amp; Hemsl.) Iokawa &amp; H.Ohashi, <em>C. decora</em> (Kurz) Schindl., <em>C. harmsii</em> Schindl., <em>C. parviflora</em> (Kurz) Schindl., <em>C. pinetorum</em> (Kurz)&nbsp;Schindl. and <em>C. sulcata</em> Schindl. The reinstatement of <em>C. parviflora</em> is proposed here and <em>C. cytisoides</em> f. <em>parviflora</em> is reduced to a&nbsp;synonym of C<em>. parviflora</em>. A key to the species and descriptions with notes on their distribution, ecological data, vernacular names&nbsp;and photographs are also provided.</p> Jiratthi Satthaphorn Peerapat Roongsattham Pranom Chantaranothai Charan Leeratiwong ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 2018-10-29 2018-10-29 46 2 138 150 10.20531/tfb.2018.46.2.05 Chelonopsis thailandica, a new species and new record of Chelonopsis (Lamiaceae) from Thailand https://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/130861 <p><em>Chelonopsis thailandica</em> A.J.Paton, Suddee &amp; Bongch. is described and illustrated here. The new species belongs in <em>Chelonopsis</em> Sect. <em>Aequidens</em> being a small shrub with an equally lobed calyx, lanceolate leaves and eglandular hairs. The new species differs from the other species in the section in having a remotely toothed leaf margin and denser indumentum. This is the first species of <em>Chelonopsis</em> to be recorded from Thailand. Only one specimen has been seen and it is possible that the habitat where the collection was made in Chiang Mai Province no longer exists.</p> Alan Paton Somran Suddee Bhanubong Bongcheewin ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 2018-11-01 2018-11-01 46 2 151 154 10.20531/tfb.2018.46.2.06
