Abstract

YUSOFF, N. S. S. M., KALU, M., & SIAM, N. A. 2025. The application of leaf anatomy identifying species of Orchidantha N.E.Br. (Lowiaceae Ridl.) in Malaysia. Reinwardtia 24(1): 17‒25. — Lowiaceae only consists of one genus, Orchidantha, which with thirty-four species has the lowest number of species among the eight families within order Zingiberales. Recently, Orchidantha has garnered attention for its potential medicinal value in treating fever, cough, chest, and back pain. The species are often only found in a small area. The morphology of the flower of Orchidantha is essential to identification but often the flowers are rarely found. As a result, this study aims to investigate vegetative anatomical characteristics of the petiole, midrib, and lamina, which could be used for species identification independent of availability of flowers; by identifying shapes and special characteristic of labellum, stigma, and viscidium. The results of this study shown a marked difference in shape and depth of the petiole grooves, petiole margin, and the number of vascular systems. In conclusion, the study demonstrates that the anatomical‒petiole grooves, petiole margin and number of vascular systems, are useful for identifying species.

Hanguana rubinea Škorničk. & P.C.Boyce (Hanguanaceae), a new record for Indonesia. Reinwardtia 24(1): 33‒39. — Hanguana rubinea Škorničk. & P.C.Boyce, originally described from and reported to be endemic to Singapore, has been discovered on Batam, Riau Islands, Sumatra and is reported here as a new record for Indonesia. The distinguishing features of H. rubinea include the silky indumentum on the abaxial surface of its leaves, the striking ruby-red hue of fruits, and the unique bowl-shaped seeds. Description and colour plates prepared from the ripe fruiting material in Batam are included together with additional notes and a map reflecting the current distribution of this species

WIDJAJA, E. A., LARASATI, I. & SUKAESIH, Y. Y. 2025. Critical notes on bamboos from Flores Island. Reinwardtia 24(1): 41‒50. — Based on the results of extended field exploration, including the taxonomic study of bamboo growing in Flores, two new species, namely Dinochloa nigroviolacea and Gigantochloa kelimutuense will be described and illustrated. It was also observed that the Timorese black bamboo Gigantochloa lako, which has not been reported before from Flores, was found growing wild in the interior of Ende Regency. Furthermore, our studies indicated that Chloothamnus schmutzii should be reduced to synonymy of Chloothamnus reholttumianus, which grows wild and has spread from Ngada Regency to West Manggarai Regency; this species is also found in East Sumba and Sumbawa. The results of our observations indicate that at present there are 17 species of bamboo growing in Flores, belonging to Bambusa (4 species), Chloothamnus (1 species), Dendrocalamus (1 species), Dinochloa (2 species), Fimbribambusa (1 species), Gigantochloa (4 species), Phyllostachys (1 species), Schizostachyum (2 species), and Thyrsostachys (1 species). They can be distinguished using the key provided

Abstract

The monotypic genus Cullenia was established by Wight (Icones PI. Ind. or. 5 (1) : pi. 1761-62 & text, 1851), who differentiated it from Durio Adans. mainly by the lack of a corolla and the position and shape of the anthers.The only species, originally described as Durio ceylanicus by Gardner, was cited by Wight as Cullenia excelsa Wight. K. Schumann corrected the specific epithet rather casually and atributed it (wrongly)to Wight. Bentham (in Benth. & Hook.,Gen. pi. 1: 212. 1867); Baillon (Hist. pi. 4: 159. 1872), Masters (in Hook, f., Fl. Br. Ind. 1: 350. 1874) and Beccari (Malesia 3: 219. 1889) accepted the genus.Bakhuizen van den Brink (in Bull. Jard. bot. Buitenzorg III, 6: 228.1924) incorporated the genus in Durio.In my opinion Cullenia represents a "good" genus by its lack of corolla.Alston, although accepting Bakhuizen's reduction, informed me personally, that he, too, is inclined to consider Cullenia different from Durio.The pollen were described as being naked and pedicellate by Gardner; this wrong statement was corrected by Wight; the anthers are pedicellate and one-celled.In this paper a new Cullenia species is described, which strengthens the position of the genus; both species are restricted to the rain forest region of Ceylon and the Southern Indian Peninsula.

Abstract

Some general notes are given on the morphology of the inflorescence and flowers in the genus Dichapetalum and on the nomenclature of the generic name Dichapetalum. An attempt has been made to revise the c. 40 species described in it from the Indo-Australian area. It appeared necessary to reduce a large number of specific names to synonymy. In the present paper 16 species have been recognized among which 4 are new. Besides, a number of infraspecific taxa have been distinguished. Pentastira Ridley, referred to the Icacinaeeae, has been reduced to Dichapetalum. A census is given of Indo-Australian species including one extra-Malaysian one, 16 D. vitiense.

Abstract

From an examination of anatomical characters it appears that the genus Scyphostegia is not related to Monimiaceae and Moraceae but represents a separate family related to Flacourtiaceae.
