Indian Abutilon (Abutilon indicum), a native shrub thought to be nationally extinct was rediscovered on Coney Island. Its subspecies, A. indicum subsp. indicum was found on Coney Island, an area predominated by Casuarina (Casuarina equisetifolia) trees. Similarly, Cyperus dubius, a sedge rediscovered in various local coastal parks in 2022 was also found among Casuarina groves. Casuarina trees are known to release allelopathic compounds that inhibit seed germination, this poses a barrier for the survival of rare native species that share the same habitat. As such, conservative measures like selective replacement with non-allelopathic native species can potentially aid the survival and regeneration of these rediscovered Singapore natives.

In recent years, several new species of flowering plants have been discovered in Vietnam, particularly in the far north and the Central Highlands region. Notably, four Gesneriaeae species have been uncovered, namely, lithophytic Allocheilos villosus with dense hairs covering on all parts of the plant, Didymocarpus tamdaoensis which is only known from one collection made at Tam Dao National Park, Didymocarpus dalatensis with downy stems and white tubular flowers, and Loxostigma vietnamensis which is endemic to the montane forest of Vietnam. These discoveries deepen our understanding of Vietnam’s rich biodiversity.

A collaboration between NParks and researchers across Singapore has identified pathogenic fungi that attack mature trees in our urban landscape. The DNA sequence of tissue samples from trees with rot, the fungal fruiting bodies and surrounding soil were analysed for unique patterns associated to individual fungal species. By comparing the results with healthy trees, 17 fungal species that cause root and trunk rot in commonly planted tree species were identified. This information leads the way for development of early detection and intervention tools of fungal disease in trees.

Botanists discovered a most unusual palm that flowers and fruits completely underground! <i>Pinanga subterranea</i> is believed to be pollinated by beetles and seed dispersal is aided by wild boars. The palm was first noticed in Lanjak Entimau Wildlife Sanctuary, Sarawak by a Malaysian botanist in the late 1990s. A team of Royal Botanic Gardens, Kew later found the palm growing abundantly in the same area in 2018. While this finding has only been recently published, the fruit is a common part of the diet of the indigenous people. This shows the importance of the knowledge of indigenous people in supporting and enriching scientific information.

Herbarium specimens of Dendrobium singaporense and Bulbophyllum gusdorfii collected nearly 30 years ago in 2001 and 1993 respectively, were uncovered in the herbarium of the Lee Kong Chian Natural History Museum, National University of Singapore. The local conservation status of these species are currently extinct and these herbarium specimens suggests that it should be reconsidered to extant. However, without any current wild sightings, the species will again cross the threshold to being presumed nationally extinct, as any species not seen in the wild for 30 years is categorized as nationally extinct in Singapore.
