Abstract

  1. The genus Pleocnemia Presl is redefined and differentiated from Tectaria Cav. and Arcypteris Underw., the latter genus being very closely related to Pleocnemia. 2. The configuration of the perispore proved to be of importance for the characterisation of the .species. In this regard three types are distinguished, perispore 1 forming crisped anastomosing wings, perispore consisting of many slender spines, and, an intermediate type, perispore forming many small separate wings.3. Tentatively 15 species are recognized. Of these, Pleocnemia winitii Holttum,P. acuminata Holttum, P. pleiotricha Holttum, P. presliana Holttum, P. dimidiolobata Holttum, P. tripinnata Holttum, and P. seranensis Holttum are described as new, aa well as one variety, P. conjugata var. elatior Holttum. 4.The following new combinations are made:P.hemiteliiformis (Racib.)Holttum (basinym:Pleocnemia leuzeana var. hemiteliaeformis Racib.),P.olivacea (Copel.)Holttum (basinym: Tectaria olivacea Copel.),P. kingii (Copel.) Holttum (basinym: Tectaria kingii Copel.), and P. chrysotricha (Bak.) Holttum (basinym: Nephrodium chrysotrichum Bak.). 5. Reductions to synonymy are: Pleocnemia javanica Presl to P. conjugata (Bl.) Presl, and Dictyopteris compitalis v. A. v. R. to P. hemiteliiformis (Racib.) Holtt

Abstract

Atuna Rafinesque(Sylva Tellur.153. 1838)with a single species Atuna ra-cemosa Rafin. has priority over Cyclandrophora Hasskarl (in Flora 25(2), Beibl. 1: 47. 1842) and as it has been described properly it has precedence over Cyclandrophora. I formerly (in Candollea 20: 118. 1965) preferred to reinstate Cyclandrophora as there is a generic name Atunus [Rumph.] Lamarck 1797, a synonym of Heritiera Dryander (Sterculiaceae). After sounding out some experts in this matter,it has become evident, that the chances to conserve Cyclandrophora against Atuna are slight and hence I give here the new combinations of the species of this genus.

Abstract

RAHMAH, KARTAWINATA, K., NISYAWATI, WARDHANA, W. & NURDIN, E. 2016. Tree species diversity in the lowland forest of the core zone of the Bukit Duabelas National Park, Jambi, Indonesia. Reinwardtia 15(1): 11 - 26. — An analysis of the composition and structure of a one-hectare plot of forest on a lowland hill slope in the eastern core zone of the Bukit Duabelas National Park, Jambi, was conducted in October and November 2012. The objective of the study was to obtain a descriptive account of the structure and tree species composition of a lowland forest in the eastern core zone of the park. The plot was divided into 100 subplots of  (10 m × 10 m) each and the seedling subplots (5 m × 5 m) were nested in the sapling subplots. A total of 414 trees were recorded with DBH (Diameter at Breast Height) ?10 cm, representing 113 species and 38 families, with the total BA (Basal Area)  of 25.71 m2 and Shannon- Wiener diversity index of 4.29. Prunus arborea with IV (Importance Value) of 19.19 is the dominant species and the other prevalent species were, Dracontomelon dao (IV =11.46) and Hydnocarpus sp. (IV =11.38). A total of 44 species (38.9%) had each density of 1 tree/ha, which may be considered locally rare. Ficus fistulosa had the highest density (24 trees/ha) and Prunus arborea had the highest BA (3.28 m2 = 12.8% of the total). Only 10 species had F (frequency) of 8-18%, of which Hydnocarpus sp. had the highest (18%); the remaining species had F<8%, which may be considered locally rare. Moraceae (IV= 34.05) was the dominant family. The two richest families were Moraceae (11) and Clusiaceae (9). A total of 61 species were registered in the Sumatra checklist and one of them was endemic (Baccaurea dulcis). A total of 13 species are listed in the IUCN Red List. The forest is a developing community after disturbance in the past with poor regeneration. Species with complete representation of trees, saplings and seedlings will probably remain in the forest in the future.

Abstract

A preliminary taxonomic study was carried out on seven Acanthaceae species namely as Andrographis paniculata,Pseuderanthemum graciliflorum,P. carruthersii, Asystasia gangetica ssp. micrantha, Ruellia repens, Justicia comata and J. betonica.The study was undertaken to investigate the morphology of trichomes present on the surfaces of flower petal. The variations found in this study are in their types and density. Based on observation, two forms of trichomes are present in all species studies which are glandular and non-glandular trichomes. There are seven types of trichomes found in this study. Trichomes types are shown to have systematic significance that can be used to differentiate and identify certain Acanthaceae species studied.

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.
