Authors: Mat Yunoh Siti-Munirah, Nikong Dome

Abstract: Thismia latiffiana Siti-Munirah & Dome, a new species from Terengganu, Peninsular Malaysia, is described and illustrated. The new species differs from all other species of Thismia, described so far, in having golden trichomes that are present on the outer surface of its floral tube and mitre, as well as pyramidal protuberances on the inner surface of the floral tube. Additionally, it is remarkable in its supraconnective apically bearing two long trichomes. Thismia latiffiana is assigned a preliminary conservation status as Critically Endangered (CR) according to IUCN Criteria.

Thismia belumensis (Thismiaceae), a remarkable new species from The Royal Belum State Park, Gerik, Perak, Peninsular Malaysia https://phytokeys.pensoft.net/article/59336/ PhytoKeys 172: 121-134

DOI: 10.3897/phytokeys.172.59336

Authors: Mat Yunoh Siti-Munirah, Zainol Suhaimi-Miloko, Mohammad Ismail Zubir Ahmad

Abstract: This report describes Thismia belumensis Siti-Munirah & Suhaimi-Miloko, a novel species of achlorophyllous herb discovered in the Royal Belum State Park, Peninsular Malaysia. This new species is unlike any previously described species of Thismia. In particular, T. belumensis possesses a unique annulus, which has been expanded and modified into a cucullate (hood-like) structure. This structure covers the apical floral tube and has an opening on one side facing a thickened part of the annulus, and the off-centre floral aperture confers a zygomorphic symmetry to the flower, indicating T. belumensis is more similar to Thismia labiata J.J.Sm. This morphological detail makes this new species distinct from all other described species of Thismia. In this report, we provide descriptions, illustrations, colour plates, and the provisional conservation status of Thismia belumensis.

Gymnosiphon syceorosensis (Burmanniaceae), the second new species for the Philippines https://phytokeys.pensoft.net/article/48321/ PhytoKeys 146: 71-87

DOI: 10.3897/phytokeys.146.48321

Authors: Daniel L. Nickrent

Abstract: A new holomycoheterotrophic member of Burmanniaceae, Gymnosiphon syceorosensis, is described from Mt. Hamiguitan located on the island of Mindanao, Philippines. This species differs from the recently named G. philippinensis from Cebu in a number of quantitative and qualitative characters. Phenetic (neighbor-joining) and phylogenetic (maximum parsimony) analyses of characters from Asian and Australian Gymnosiphon species were conducted and diagnostic taxonomic features were discussed. This new species appears to be most closely related to G. affinis J.J. Sm. from New Guinea but differs in a number of floral features including inner perianth lobe shape, stamen position in floral tube, and anther connective shape.

Thismia domei and T. terengganuensis (Thismiaceae), two new species, and T. javanica, a new record from Terengganu, Peninsular Malaysia https://phytokeys.pensoft.net/article/34728/ PhytoKeys 124: 123-137

DOI: 10.3897/phytokeys.124.34728

Authors: Mat Yunoh Siti Munirah, Dome Nikong

Abstract: Two new species of the mycoheterotrophic genus Thismia Griff. (Thismiaceae), Thismia domei Siti-Munirah and T. terengganuensis Siti-Munirah from Peninsular Malaysia, are described and illustrated. Thismia domei, characterized by its perianth lobes that are upright and curve inward, but are imperfectly connate, falls within section Odoardoa. Thismia terengganuensis is characterized by its mitre with three appendages on its apex, so falls within section Geomitra. Both new species are unique and totally different from other described species, T. domei by the trichomes on its outer perianth tube surface and T. terengganuensis by its mitre with slender appendages. Thismia javanica J.J.Sm, also from Terengganu, is a new record for Peninsular Malaysia.
