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

TAN, A. L., KAMAL, N. M., TAN, H. P. & ROSLAN, I. 2015. Notes on morphological characteristics of Eurycoma spp. and its status in Peninsular Malaysia. Reinwardtia 14 (2): 259 - 263. - A study had been carried out on the genus Eurycoma Jack that aimed to ascertain the diagnostic characteristics of the two species that occur in Peninsular Malaysia. Samples were collected from 15 localities comprising of forest reserves and plantations throughout Peninsular Malaysia covering the 5 regions i.e. northern, western, eastern, southern and central. The sampling was done to capture the morphological variations from different habitat. In general, morphologically both species were very similar. They could be clearly distinguished using their fertile parts. Eurycoma longifolia Jack had long, drooped inflorescences while in E. apiculata A.W. Benn was usually short, pointed upwards. Small differences were also noted on the leaflet of E. apiculata where the apex of the leaflet was often abruptly pointed while its base was rounded with conspicuous petiolule. On contrary, E. longifolia leaflet apex was usually subacute with its base asymmetrical and decurrent to its petiolule. In addition, anatomical transverse section of E. longifolia leaflet midrib outline and margin were dissimilar with E. apiculata by having convex abaxial surface and blunt tip margin compared to the slightly arc-shape abaxial and tapered margin in E. apiculata. The abundancy of Eurycoma spp. had decreased.

Abstract

A key is given to 38 species of which 29 are either native or introduced in Malaysia; 9 others have been reported from Malaysia, but no material was found to justify these records. They have been marked by an asterisk before their number.Crotalaria grandiflora Reinw. has been reduced to C. tetragona Andr.C. lejoloba Bartl. is probably the oldest name for C.ferruginea Grah. ex Bth., but as no type material could be located the latter name has been maintained for the time being.Some sheets of the Philippines identified as C. acicularis Buch.-Ham. ex Bth. have proved to belong to C.humifusa Grah. ex Bth. which is a new record for these islands.C. medicaginea Lamk. and C. trifoliasU-um Willd.have sometimes been merged; they are kept apart in this paper.A new record for Malaysia is the African C. cleomifolia Welw. which has been introduced in the Malay Peninsula as a green manure; whether it has spread as a weed is uncertain.Another newly recorded species in Malaya is C.undtiella Lamk. collected in 1954 for the first time locally in abundance along the sandy beach.C. prostrata Rottl.is newly recorded for the Philippines.Among the species a few are indifferent to climate, but most apparently prefer the occurrence of a dry season in various degree. In mapping the areas it has been found that they can easily be arranged in the drought classes distinguished in the first instalment.An index to synonyms and a list of collector's numbers have been added at the end.

Abstract

An analysis of the composition and structure of lowland natural forests was carried out in Bodogol, Gunung Gede Pangrango National Park (GGPNP). The two study plots (P1CS and P2CS) were located on Cisuren and one plot (P3CP) on Cipadaranten hill. We recorded 107 species and 48 families with an average basal area of 19.73 m2/ha, and an average density of 348 trees/ha. The species richness was poorer than those of the typical lowland rainforests of Kalimantan and Sumatra but comparable to those of the montane forests of Java. The IUCN-Red Listed species were Castanopsis argentea and Castanopsis tungurrut (critical) and Saurauia bracteosa (vulnerable). Based on the two dominant species, the forests can be designated as the Maesopsis eminii-Syzygium acuminatissimum association and Syzygium acuminatissimum-Lithocarpus korthalsii association. Maesopsis eminii was dominant in P1CS (IV= 56.46%) and P3CP (IV=55.94%), while Syzygium acuminatissimum in P2CS (IV= 43.67%). Maesopsis eminii was a strongly aggressive and invasive species, that endangered the purity of the natural forest GGPNP, therefore, it must be eradicated. Vertically, P2CS and P3CP consisted of four strata, while P1CS had three strata. This one-hectare study can be considered as a minimal area to reflect the floristic representation of lowland forest and submontane forest.

Abstract

Pandanaceae is placed in the superorder Pandaniflorae and the order Pandanales, indicating its uniqueness when compared with the other seed plants. Pandanaceae contains three genera, Pandanus, Sararanga and Freycinetia. Limited collections seem to be one reason why botanical illustrations are made, so that people can enjoy their "collections" from a picture painted on canvas. Botanical illustration is one type of record that can also give evidence about whether the plant exists. In addition, botanical illustration can give information about the growth of the plant, and historical evidence can be traced. There is no doubt that Pandanus has also been well illustrated. Later, further developments in Pandanus research obviously influenced the illustrations of Pandanus.

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.
