Summary: We describe and illustrate Nervilia singaporensis Niissalo, a small Southeast Asian terrestrial orchid which has only been collected in Singapore. This is a mostly cleistogamous species, superficially similar to other cleistogamous species in the Nervilia adolphi/punctata species alliance. Most flowers never open but develop immediately to seed capsules. Unlike many species in the genus, N. singaporensis lacks strict vegetative, dormant and flowering seasons and flowering and fruiting plants can be found year‐round, sometimes simultaneously with the leaves. This genus is poorly understood in Malesia, which could explain why this species has not been recorded in other countries.

Summary: A description and illustrations are provided for Hanguana neglecta Škorničk. & Niissalo, an interesting forest herb known only from Singapore and Peninsular Malaysia. This species can be readily identified by its small habit with predominantly upright leaves, trilobed clover leaf‐shaped stigma, black fruits, and characteristic seeds that feature a deep excavation and a wedge‐shaped ostiole.

Summary: A description and illustrations of Zingiber singapurense Škorničk., a critically endangered ginger, are presented with notes on cultivation and recent conservation efforts. The species is endemic to Singapore and known under the common name, SINGAPORE GINGER. Key characters for the recognition of this species include narrow dark green leaves and an inflorescence composed of a peduncle and an orange‐red fusiform spike bearing pale yellow flowers. Interestingly, this species is pseudoviviparous, producing young plantlets at the end of mature and old leafy shoots, which readily root upon contact with the ground.
