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

Five species of Mastixia are found in Sri Lanka, of which M. congylos and M. nimalii are here described for the first time, whereas M. tetrandra var. thwaitesii is raised to specific rank as M. montana. M. arborea does not occur in Sri Lanka. A key to the species is presented and the specimens examined are enumerated.

Abstract

There are only two species of Mangifera, M. duperreana Pierre from Indochina and M. lagenifera Griff, from Malay Peninsula and Sumatra, which were described to have flowers with 10 (—12) stamens, of which 5 (or 6) are fertile. In the latest monograph of the genus by Mukherji (in Lloydia 12,1949: 73 — 136), they were placed in two different sections (without naming the sections). According to him, the floral morphology of these two species shows that they "possess the most primitive feature in the genus (pentacyclic flowers)" (cf. J. Linn. Soc. Bot. 55, 1953: 75). In the course of revising this genus for the Flora Malesiana, a new species having flowers with also ten stamens was discovered, which has been named and described here as Mangifera decandra (= ten-stamened; in Gk: deca-, ten; andro-, male) ; its epithet alludes to the significant number of stamens.

Abstract

1. An account of the genus Tetracera L. in the eastern Old World (Asia, Malaysia,Australia, New Caledonia) is given. The Malaysian species have already been in cluded in the revision of the Dilleniaceae in "Flora malesiana" (I 4: 141-149. 1951). 2. The main part of the present paper consists of a key to the species, followed by a systematic treatment of the 15 species admitted for the region. 3. Latin diagnoses are given for three new subspecies under Tetracera asiatiea (Lour.) Hoogl. and two new varieties under Tetracera nordtiana F. Muell. 4. A number of species are reduced either to the rank of variety or to synonymy. 5. Distribution-maps are provided for the species of which a relatively large number of specimens has been studied.

Abstract

Palms (Arecaceae) are an important component of many tropical rainforests. Many have also been cultivated widely for agricultural commodities with high economic value. They are also important components in rehabilitation of disturbed or marginal lands. Knowledge and application of germination strategies are essential in the cultivation of palms. Many species have seeds that do not germinate readily, even when light conditions are favourable. This research determined the effects of seed coats, light and temperature on germination of Arenga australasica (H. Wendl. & Drude) S. T. Blake ex H. E. Moore, Calamus australis Mart., Hydriastele wendlandiana (F. Muell.) H. Wendl. & Drude and Licuala ramsayi var. tuckeri Barford & Dowe. We examined physical treatments to promote germination or break dormancy, as well as different light and temperature conditions. The results showed that the hard seed coats of the four species slowed imbibition. Scarified seeds germinated best for A. australasica, C. australis and L. ramsayi. The germination of all seeds was inhibited by far red light. The red light requirement suggests that these species prefer to colonise open areas. This implies that dispersal agents, canopy gaps and forest margins may play important roles in promoting regeneration as well as conservation of these palm species.

Abstract

Study on leaf nutrient status in the primary lowland dipterocarp forest has been carried out at Mulawarman University research forest, Lempake, Samarinda. Six elements i.e. N, P, K, Na, Ca and Mg were analyzed. Results show that the dominant species and family seemed to be controlling and maintenance the main mineral nutrients in this forest ecosystem. There were a variation of mineral nutrients between species and also a fluctuation of mineral nutrients in the different period.
