On The Agaric Genera Hohenbuehelia and Oudemansiella Part I. Hohenbuehelia [Page 7 - 47]
Abstract:
The construction of the fruit-body and the affinity of the genus are discussed. It is considered that it comes between Pleurotus and Oudemansiella, having the basidia of the former and the pleurocystidia of the latter. Eighteen species are described for Malesia, of which 15 are new. Notes are given on several extra- Malesian species. New taxa: H. concentrica, H.griseipendens, H. incarnata, H. lanceifera, H. malesiana, H. mellea, H. minutissima, H. pachyhyphata, H. pahangensis, H. perstriata, H. quadruplex, H. singaporensis, H. suppapillosa, H. vermiculata, H. bullulifera Singger v. brasiliensis. New combinations: H. cystidioides (C.G.Lloyd), H. subtorulosa (Cke).

On the Agaric Genera Hohenbuehelia and Oudemansiella Part II: Oudemansiella Speg. [Page 49 - 75]
Abstract:
This is mainly an account of Malesian species, of which O. crassifolia, O. lianicola and O. submucida are new, but notes are added on several temperate and South American species. The structure of the pileus introduces a new criterion into the specific classificalion of the genus. The connection with marasmioid Xerula is discussed. A species from Japan, referred tentatively to O. radicata var. hygrophoroides (Sing. et Clemoncon) Pegler et Young is intermediate in that it has the marasmioid subacerose basidioles in the hymenium. It is suggested that the narrow basidia of Hohenbuehelia and Pleurotus and the subacerose basidioiles in the hymenium. It is reaffirmed that the pleurocystidia conform with the basidiograph locus of Oudemansiella and it is suggested that the narrow basidia of Hohenbuehelia and Pleurotus and the subacerose basidiioles of Marasmius correspond with the developing and uncharged basidia of Oudemansiella.

Citrus Fruits of Assam: A New Key to Species, and Remarks on Citrus assamensis Bhattacharya and Dutta, 1956 [Page 105 - 112]
Abstract:
The revision of Citrus in Assam by Bhattacharya and Dutta, 1956, is a work on citriculture and citrus taxonomy the importance of which is not limited to the Asean region; it contains a new species, C. assamensis, and a key to all the Assam citrus, as well as full descriptions of all taxa including the floral features The utility of this work is enhanced by illustrations but constructional errors in the key have prevented its correct and effective use. A new key expressing the authors' intentions, as well as remarks on Citrus taxa and relationships and notes on the typification of C. assamensis are represented in this paper.

Supplement to the Rutaceae in Peninsular Malaysia [Page 121 - 140]
Supplement to the Rutaceae in Peninsular Malaysia [Page 121 - 140]
Abstract:
Since the publication of the Rutaceae in the "Tree Flora of Malaya" (vol.I.,1972), there have been a number of changes both bibliographic and taxonomic which ought to be accommodated in this account. The genus Terminthodia has been subsumed within Tetractomia; a new genus Maclurodendron has been established to include some species formerly placed in Acronychia; and Tetradium has been revived to hold certain species of Euodia. The remaining species of Euodia are now believed to be most correctly placed in Melicope. They are herein revised by T.G.Hartley. His account shows that Melicope is represented in Peninsular Malaysia by 10 species. Among these, M. corneri T. Hartley is proposed as a new species, M. pahangensis T. Hartley as a new name, and M. pachyphylla (King) T. Hartley and M. macrocarpa (King) T. Hartley as new combinations. In the Aurantioideae, there are now improved treatments of Glycosmis and Citrus, and the plant referred to as "Citrus sp. A" in the 1972 treatment was subsequently described as a new species, C. halimii. Some controversial matters such as the discrimination ot certain genera and species are discussed herein. Finally the key to genera, which was imperfect, has been reworked and corrected. This account thus summarizes these details and presents, where useful, a new treatment to substitute for the old; it should be used in conjunction with the 1972 treatment. To facilitate use, the keys, generic, and specific accounts are set out here in the same form as in that volume.

The Taxonomy, Distribution and Ecology of the Epiphytic Malesian Ant-Fern Lecanopteris Reinw. (Polypodiaceae) [Page 293 - 335]
The Taxonomy, Distribution and Ecology of the Epiphytic Malesian Ant-Fern Lecanopteris Reinw. (Polypodiaceae) [Page 293 - 335]
Abstract:
Lecanopteris comprises 13 epiphytic species with expanded rhizomes which shelter ants in a mutualistic association. Taxonomic descriptions and a key are given. In subgenus Myrmecopteris, L. sinuosa occurs throughout Malesia, in most habitats below 800m a.s.I., especially in the ant-epiphyte communities of dry forest. Lecanopteris crustacea is confined to Bomean. Sumatran and Malaysian lowland dipterocarp canopies. Its sister species, L. sarcopus occurs in intact and disturbed forest from 400-1200m in the Philippines and Sulawesi. Lecanopteris mirabilis is found in New Guinea, Ambon and Seram, and is locally abundant in undisturbed mid-montane forest. Subgenus Lecanopteris consists of three groups. typified by L. curtisii, L. pumila and L. darnaedii. Lecanopteris curtisii forms distinct races in New Guinea, the Philippines, Sumatra, Java and Borneo. It is a rare member of intact or old disturbed hill forest between 400m and 1200m. The L. pumila group contains three endemics of lower montane forest in Sulawesi: L. celebica, L. casnosa and L. balgooyi, and a Philippine endemic, L. luzonensis, Lecanopteris pumila is found in mid-montane forest and ridgetops in Malaysia, Sumatra and Borneo, where it forms distinct races. The L. darnaedii group is endemic to Sulawesi; the three species are allopactric and found in undisturbed mid-montane forest. Myrmeco-epiphytic communities, inhabited by Iridomyrmex cordatus, are found in Bornean heath forest and New Guinean savannah. The ants contribute to the spread of ant-epiphytes by planting their propagules in the ant carton surrounding L. sinuosa. The only ecological characteristic common to Lecanopteris apart from myrmecophytism is heliophily, confining individuals to habitats with open canopies or tree crowns. No preference is manifested for host species, but Lecanopteris tends to grow on rough-barked trees.

Notes on the Development of the Fruit-bodies of Four Malayan Species of Amanita (Basidiomycetes) [Page 43 - 45]
Notes on the Development of the Fruit-bodies of Four Malayan Species of Amanita (Basidiomycetes) [Page 43 - 45]
Abstract:
The development of the fruit-bodies was observed under natural conditions in the forest. Those of A. elata, A. princeps and A. virginea took 12-14 days to reach maturity when they persisted for merely 1-3 days. Expanded fruit-bodies soon became fly-blown and this hastened their decay. A. elata and A. princeps fructify early in the fungus season, as do most Malayan species, but A. virginea appears towards the end of the season. The presence of these species is revealed only for a few days twice each year.

A Botanical Survey of Pulau Ubin [Page 51 - 71]
Abstract:
An intense botanical survey of Pulau Ubin, a 1019, 2 ha island within the Republic of Singapore, found at least 332 native and naturalized vascular plant species. These are listed in the paper together with 40 species found to have escaped from cultivation. Previous botanical records for Pulau Ubin are also collated. The contemporary flora is dominated by early successional and ruderal species in addition to mangrove and beach forest elements. The low diversity and relatively high frequency of aliens (71 out of 332 spp.; 21 per cent of the flora) reflects the high degree of human disturbance on the island.

Karyomorphology of Some Myrtaceae from Singapore [Page 135 - 139]
Abstract:
Karyomorphology of five species in three genera of Myrtaceae, namely Callistemon, Melaleuca, and Syzygium, is investigated. All five species examined have similar chromosome features at mitotic interphase, prophase, and metaphase. Mitotic metaphase of their somatic cells consistently show 2n = 22, of which 18 chromosomes have centromeres at median position and four at subterminal or terminal position. Syzygium aromaticum has a secondary constriction in the longest pair of chromosomes as in several other related and unrelated species of the family, a fact suggesting that the presence of the secondary constriction may be of some taxonomic use.
