Recent fieldwork in Terengganu, Peninsular Malaysia, resulted in the collection of an endemic new species of Ardisia, described here as Ardisiarecurvipetala Julius, Siti-Munirah & Utteridge. The species is a member of subgenus (§) Crispardisia on account of its vascularised glands (bacterial nodules) on the leaf margin and the terminal inflorescence on a specialised lateral branch subtended by a normal leaf (rather than a reduced bract-like leaf). Ardisiarecurvipetala is unique amongst all members of §Crispardisia by having leaf margins with both vascularised glands and pustule-like structures and can be further distinguished from other Peninsular Malaysian members of this subgenus by the lamina raised between the leaf venation giving a somewhat bullate appearance, unbranched inflorescences, brownish-red pedicels and recurved corolla lobes, each with a creamy-white apex and a small pink patch at the base. Ardisiarecurvipetala is known only from a single location in Terengganu and its conservation status is assessed as Data Deficient (DD).
A checklist of the bryophyte flora of Mount Tebu Forest Reserve in Terengganu, Peninsular Malaysia, is presented. A total of 189 taxa in 71 genera and 26 families were enumerated. This figure represents 63% of the 298 bryophyte species recorded so far for the State of Terengganu. Out of 189 taxa of bryophytes, 26 liverworts are new additions to the bryoflora of Terengganu. The most prominent liverwort family is represented by Lejeuneaceae, with 54 species from 17 genera, while the moss family is the Sematophyllaceae, with 34 taxa in 13 genera. The majority of the species are epiphytes, either corticolous or ramicolous. Almost half of the bryophyte species have wider elevational ranges and occur from the lowlands to the summit of Mount Tebu.
Two new species of Aglaia from Indonesia are described, Aglaia monocaula restricted to West Papua, and Aglaia nyaruensis occurring on Borneo (Kalimantan, Brunei, Sabah and Sarawak). A phylogenetic analysis using nuclear ITS and ETS, and plastid rps15-ycf1 sequence data indicates that the two new species of Aglaia are also genetically distinct. Aglaia monocaula belongs to sectionAmoora, while A. nyaruensis is included in section Aglaia. A dichotomous key, drawings and three-locus DNA barcodes are provided as aids for the identification of the two new species of Aglaia. In addition, the geographic range of Aglaia mackiana (section Amoora) is expanded from a single previously known site in Papua New Guinea to West Papua, Indonesia.
Ardisiakrauensis, a new species of Primulaceae from Peninsular Malaysia, is described and illustrated. The new species is assignable into subgenus (§) Pyrgus on account of specialised lateral reproductive branches bearing a terminal inflorescence subtended by foliose bracts. Morphologically, the new species mostly resembles Ardisiarigida in having elliptic leaves. However, the new species can be distinguished by the combination of its lateral veins number, the inflorescence branching pattern, the rachis and flower colour, and the stigma shape. Ardisiakrauensis is found in an entirely protected habitat, thus, it is assessed as Least Concern (LC).
