“…in Pahang and the Neotropical naturalised species Spigelia anthelmia L. (both Loganiaceae ) in Selangor ( Julius et al 2013 ). Many other new species have also been described from various other plant families, including Aristolochiaceae ( Yao 2012 ), Balsaminaceae ( Kiew 2016 ), Capparaceae ( Julius 2022 ), Gesneriaceae ( Kiew and Lim 2019 ; Syahida-Emiza et al 2020 ), Orchidaceae ( Ong et al 2020 ; Ong 2021 ), Thismiaceae ( Siti-Munirah 2021 ; Siti-Munirah and Dome 2019 , 2022 ; Siti-Munirah et al 2021 ) and Zingiberaceae ( Sam et al 2009 , 2012 ; Sam and Ibrahim 2018 ). This highlights the rich biodiversity of Peninsular Malaysia and opportunities for more discoveries ( Middleton et al 2019 ).…”

Recent fieldwork in Terengganu, Peninsular Malaysia, resulted in the collection of an endemic new species of Ardisia, described here as Ardisia recurvipetala 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). Ardisia recurvipetala 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. Ardisia recurvipetala is known only from a single location in Terengganu and its conservation status is assessed as Data Deficient (DD).

The family Zingiberaceae or known as the ginger family of flowering plants famous for its medicinal values and is widely distributed especially in Southeast Asia. Malaysia is one of the countries with abundance of Zingiberaceous species. Usually, identification of the plant species begins by identifying the leaves. Identification based on leaf recognition is the most effective method because a healthy plant has leaves and it exists all the time, unlike fruits and flowers which may only exist at certain times. However, the leaf recognition considered as intricate task and challenging especially when using conventional approaches as most plants have similar shape and colour. Thus, the aim of this research is to develop an interactive application for classification and identification of selected Zingiberaceae species, namely: Zingiber officinale, Curcuma longa, Etlingera elatior and Alpinia galanga based on leaf recognition using multiclass Support Vector Machine (SVM). Six steps were constructed to develop an interactive application for classification of Zingiberaceae species: 1) Collection of leaf samples, 2) Creation of database from captured leaf images, 3) Image preprocessing, 4) Leaf image processing, 5) Classification of image textures using SVM and 6) Design of graphical user interface (GUI). The image features extraction in leaf image processing were based on gray-level co-ccurrence matrix (GLCM), Canny and Prewitt algorithms. The combination of GLCM and Prewitt achieved the highest accuracy which was recorded of 95% from the overall accuracy in classification of Zingiberaceae species. By using the automatic plant identification system, results will come up more accurate and faster.
