Reinwardtia is a peer-reviewed scientific journal dedicated to advancing the understanding of plant science, with a particular emphasis on three core areas: plant taxonomy, plant ecology, and ethnobotany. The journal serves as a vital platform for disseminating research that explores the classification, identification, and relationships of plant species (taxonomy), the interactions between plants and their environments (ecology), and the traditional knowledge and cultural significance of plants (ethnobotany). Reinwardtia places a strong focus on the flora of Southeast Asia, a region known for its rich biodiversity and complex ecosystems. It extends its coverage to neighboring regions, including the tropical areas of Northern Australia, providing insights into the plant life of these biologically diverse areas. The journal seeks to contribute to the global scientific community by publishing original research articles, reviews, and notes that deepen the understanding of plant species in these regions and their ecological and cultural contexts.

Abstract

Lithocarpus Bl. (1826) is here considered to include the following genera: Synaedrys Lindl. (1836), Cyclobalanus (Endl.) Oersted (1867, p.p.),and Pasania (Miq.) Oersted (1867, p.p.).In Malesia 104 species are recognized, of which 25 are new to science and 7 are new combinations.Apart from these there are 10 more species which are considered as doubtful,as from the specimens so far examined it is difficult to decide their correct status. Pasania littoralis (Bl.) Oersted (basionym: Quercus littoralis Bl.)is excluded from the genus, and the species has been reidentified by Dr. A.J.G.H.Kostermans (Bogor) as Atuna scabra (Hassk.)Kosterm.In Malesia most species of Lithocarpus may be distinguished from those of Castanopsis by the ridged inner surface of their bark, uniseriate and multiseriate wood-rays,spiral arrangement of leaves and bud-scales,and by their cupule which always encloses one fruit only, and which are solitary or in dichasial clusters along the rachis, possessing interseminal cupule segments and a scattered pattern of vascularization.

Abstract

Amongst the lichens sent by the late Mr C. C. Schroter at Tjibodas (West Java),a peculiar blue-grey species drew my attention.At first sight I intended to assign it provisionally to Collemaceae indeterminatae,but on closer examination I doubted whether it was really a species of Collemaceae.Therefore.I examined it more carefully, with the following result.The granular thallus grows in smaller to larger patches over mosses,lichens, and detritus on bark.Soredia and isidia are absent and the thallus is not surrounded by a dark hypothalline line.The granular appearance of the thallus is caused by the relatively large gonidia, which belong to Stygonemataceae.The yellowish green cells are rounded,angular to semilunate, 8—12µ, wide and 10—15 µ long; one or more of them are enclosed within a gelatinous,colourless to pale citrine sheeth 4—6µ thick. These clusters of gonidia are held together by the thalline hyphae constituting in this way a homoiomeric thallus.There is some resemblance with the thallus of Moriolaceae but in this family the gonidia are totally surrounded with a network of short hyphae lying close together.In the thallus of Cyanoporina, as I call this new lichen, such a network does not exist.The hyphae lie irregularly around the gonidia and cover them but partly. These gonidial hyphae are 2—3µ thick and possess very short cells. The thalline hyphae are 3 µ,thick, with inconspicuous lumen.Even with the aid of a dissecting microscope the perithecia are almost invisible.Most of them are covered by the granules of the thallus.Yet the thallus is abundantly fruiting and in sections perithecia are always present. They are globose, 110—130µ in diameter, pale fulvescent to yellowish, with a pseudoparenchymatic wall 10—12 µ thick, composed of densely interwoven hyphae. I could, not discover a pore.The paraphyses are diffluent and only fragments were found.

Abstract

The American species of Phoebe Nees are relegated to Cinnamomum Trew; the reasons for this transfer are discussed. To retain nomenclatural stability the new combinations which have become necessary are presented, in anticipation of a general revision of the genus Cinnamomum; 68 new combinations and names are presented.

Abstract

Study in leaves anatomy of twenty nine samples of the species classified under Pandanus, Freycinetia and Sararanga of Pandanaceae had been undertaken to unravel generic relationship among of these taxa with a view to provide a set of diagnostic characters for taxonomic identification. The fourth genus of Pandanaceae, Benstonea is not included in this analysis since there are no representative samples. Four anatomical diagnostic characters had been identified at the generic level such as present and absent of papillae, stomatal arrangement types, present and absent of bundle sheath extension and hypodermal thickness and its shape. Pandanus has papillae, amphistomatous stomata, bundle sheath extension present and hypodermis thin and rectangular; Freycinetia lacked of papillae, stomata hypostomatous or amphistomatous, bundle sheath extension absent and hypodermis thick and hexagonal or rounded; meanwhile Sararanga has no papillae, stomata amphistomatous, bundle sheath extension absent and hypodermis thin and flatten. An identification key to those genera based on anatomical diagnostic characters is provided.

Abstract

In working up the sterculiaceous specimens from the Herbarium of the Indian Botanic Garden in Calcutta I have encountered a specimen of Durio which represents apparently a hitherto undescribed species. The description of this species is presented here. Gratefully I acknowledge my thanks to the Director of the Calcutta Herbarium for the loan of the specimen together with the excellent drawing from which the figure published here has been copied partly.

Abstract

ROBIANSYAH, I. 2017. Predicting habitat distribution of endemic and critically endangered Dipterocarpus littoralis in Nusakambangan, Indonesia. Reinwardtia 16(1): 11 - 18. - The tree species Dipterocarpus littoralis (Bl.) Kurz. is endemic to Nusakambangan and categorized as critically endangered. In the present study, the habitat suitability of the species in Nusakambangan was predicted using logistic regression analysis and Maxent model. Three topographic variables (elevation, slope, and aspect), distance from river and coastline, and one vegetation index (Normalized Difference Vegetation Index (NDVI)) as well as two water content indexes (Normalized Difference Water Index (NDWI) and Normalized Difference Moisture Index (NDMI)) were used as predictors of the models. Employing initial number of 82 presence and 250 absence data of D. littoralis, both models were able to predict the suitable areas for the species with fairly high success rate. The AUC and Kappa value for logistic regression were 0.77 ± 0.027 and 0.34 ± 0.058, respectively, while the respected values for Maxent were 0.91 ± 0.062 and 0.37 ± 0.025. Logistic regression analysis identified a total area of 26.13 km2 to be suitable for D. littoralis, while a smaller suitable area (7.85 km2) was predicted by Maxent model. Coastal areas in the west part of the island were predicted by both models as areas with high suitability for D. littoralis. Furthermore, distance from coastline and river, elevation, NDVI, NDWI and NDMI were suggested to be very important for the species ecology and distribution. The results of this study may serve as a basis for population reinforcement and reintroduction programs of D. littoralis and guide for ecosystem management of Nusakambangan Island as a whole.
