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

Using the Braun-Blanquet and ordination techniques, nine dry-grass community types were recognized on Oahu,seven of which were dominated by exotic grasses and two by native grasses, Hctcrnpogna eontortus and Erarjrostis variabilis.These community types occured in summer-drought, summer-dry and humid climates.The distribution of certain community types could be correlated directly with rainfall and soil pH. In the summer-drought climate the occurrence of the community types was related to topography,wind exposure, rockiness of the land surface and stoniness of the soil.The nine community types were not related to the established soil series, organic matter content and watsr retaining' capacity of the surface soils.Three distinct soil-water regimes were recognized in five community types: drought, dry and wet types.Seasonal variations in soil-water content were correlated closely with the rainfall pattern.The introduction and spread of exotic species resulted in a gradual disappearance of the native grass communities in the summer-drought zone. In the summer-dry zone, Grevillea robiista. trees and Meliiiis minutiflora grass mats were invading the Rhynchelytrum repens community. Artdropogon virginiciis, introduced in 1932, formed a wide spread herbaceous community in the humid zone. In some places, this community was invaded by Dicranopteris linearis fern mats and trees of Acacia, koa or Metrosideros collina. Fire in both the summer-dry and humid zones maintained and extended the grass communities.

Abstract

Three species of green algae and one blue-green alga were recorded from eight samples of soil found associated with bryophytes in the Cibodas Forest Reserve. Chemical analysis of the soil showed severe leaching of soluable mineral substances associated with a low pH. The low light intensity under forest conditions and the low pH may account for the limited algal flora.

Abstract

In July and August 1972, I spent five weeks on an expedition to study rattans and other palms in the provinces of Jambi and West Sumatra. This central area of Sumatra was chosen because expeditions have already been made to South Sumatra in February 1971 and March 1972 and to North Sumatra and Aceh with the Kyoto University Expedition in August 1971, and therefore collections made in this central area would link up collections from the south and north and would hence add considerably to our knowledge of the palm flora of this rich island. After advice from the Department of Nature Conservation in Jambi and from Dr. M. Jacobs in Rijksherbarium (Leiden) had been considered, it was decided to work westwards from Berbak Nature Reserve on the east coast near Nipah Panjang, to the Bukit Barisan, the main range of Sumatra, to Gunung Kerinci Nature Reserve and G. Tujuh near Sungai Penuh and from there, across the western part of the Bukit Barisan to Padang and Bukittinggi. From Bukittinggi it was planned to visit the Kafflesia arnoldii Nature Reserve at Batang Palupuh, and then return to Jambi by way of Muara Tebo and Muara Tembesi, where reputedly there still exists lowland forest. By more or less confining our collecting activities to the normally neglected Palmae it was hoped that within the time available a large area could be covered reasonably, and a palm transect for central Sumatra made. Two assistants from Bogor accompanied me to help in the difficult task of collecting rattans: Dedy Darnaedi (Herbarium Bogoriense) and Abdul Hanan (Kebun Raya). These assistants were also given individual collecting assignments as part of a scheme for training assistants in field botany. Dedy was to collect Pteridophyta and Hanan to collect material for growing in the Kebun Raya. Soetrisno Soewoko, head of Nature Conservation in Jambi accompanied us throughout tha expedition.

Abstract

This is the first taxonomic revision of this pantropical genus of prickly climbers for the area, the Solomons inclusive.It deals with 21 species, of which 19 ore native (dealt with over the whole of their area),and 2 are widely naturalized, viz C. pulckerrima and C. sappan.Also mentioned are 3 occasional introductions. Full descriptions are given,keys to the native and to the cultivated species, the complete synonymy and typification with all important later references.Many new deductions have been made,some from adjacent regions. New species are C. opptrsitifolia, from Borneo, with truly opposite leaves and C Bolomonewsis from the Solomons; new combinations are C.andamanica based on Mezoneuron andamanicum Prain,C furfuracea based on M. furfuraceum. Prain, C. hymenocarpa based on M, hymeno carpum Prain,C latisiliqua based on latisiliquum (Cavan) Merr,C. mindorensis based on M. mindorense Merr., C. pubeecens based on M. pubescens Desf., C. scorteckinii baaed on M. scortechinii F.v.M. from Queensland and now on record from New Guinea, the last one closely resembling C. brachycarpa, another new combination based on M. braehycarpmn Benth, from New South Wales.No subdivisions of the genus are adopted or proposed. The long standing nomenclatural confusion hetween C. bonduc, C. bonducella,C. cristrt, and C. major has been visualized in a diagram. Specimens of importance for the knowledge of the area have been cited. Extreme and intergrading specimens are discussed. Eeference is made to the main ecomonic literature Indexes to all names and all specimens are given.
