MATERIALS FOR A REVISION OF LAURACEAE IV*

In the genus Actinodaphtie Nees one new combination and one new species ace presented; in LAndera Thunb. one new combination, 4 new species and one new forma; in lAtsea Lam. one species has been reduced to synonymy, one nomen novum is presented, 5 new species are described and of 6 species new cecords are given; one species has been reinstated. The obscure Mackilus sericea Bl. is a3sumed to be conspecific with Persea bombyeina (King ex Hook, f.) Kosterm. In the genus Persea Mill. one nomen novnm, two new combinations and one new species are created and proposed. In the genus Phoebe Nees one new combination and two new species are presente

THE GENUS CYNOMETRA (LEGUMINOSAE) IN CEYLON

In Ceylon 2 species of Cynometra occur, the wide spread C. iripa of the mangroves, which was enumerated as Cynometra ramiflora var. heterophylla by Thwaites and wrongly included in C. ramiflora by Knaap-van Meeuwen and the new species C. zeylanica Kosterm., formerly thought to be the Malesian C. ramiflora. The latter, as defined by Prain and based on a Rumphian plate, does not occur in Ceylon. Cultivated is the Malesian C. cauliflora with a white- and a pink-flowered forms

New species are described in Actinodaphne (2), Beilschmiedia (1), Cinnamomum(14), Endiamdra (20), Lindera (1), Litsea (8).New combinations are made in Cinnamomum (2), Litsea (2), Neolitsea (1).New names are proposed in Persea (2), Beilschmiedia (1).One variety is created in Cryptocarya.Endiandra fragrans Allen is reinstated.Reductions, are made in Actinodaphne (2), Beilschmiedia (2), Cryptocarya (15),Endiandra, (6), Endlicheria (1), Haasia (1), Lindera (3), Litsea (41), Persea (1), Phoebe(1), Tetranthera (12).New records are cited for most species.First record of Caryodaphnopsis tonkinensis from New Guinea

A MONOGRAPH OF THE GENUS DIPLODISCUS* Turcz. (TILIACEAE)

1. Seven species of the genus Diplodiscus are described, of which three (D. microlepis, D. parviflorus and D. decumbens) are new to science, and one (D. hookerianus) was formerly described as Pentace (for the description of D. decumbens cf. p. 264).2. The area of distribution of the genus covers the Malay Peninsula, Borneo and the Philippines.3. The affinities of the genus are discussed.4. A key to the species is presented

DURIO MACRANTHA KOSTERM., SPECIES NOYA (BOMBACACEAE) FROM NORTH SUMATRA

An interesting species of Durio from Sumatra is described and illustrated from a living specimen growing in Bogor

BERRYA ROXB. and CARPODIPTERA GRIS.

In his monographic treatment of Tiliaceae, Burret {in Notizbl. bot.Gart. Berlin 9: 607. 1926) pointed out the close affinity of Berrya andCarpodiptera, the former represented in Asia and the Pacific area, thelatter from Africa and America

NOTES ON TWO LEGUMINOUS GENERA FROM EASTERN INDONESIA

 1. A new monotypic genus, Kalappia Kostermans, is established for a tree of commercial importance from Celebes, K. celebica Kostermans. The genus is assigned to Caesalpiniaceae (Tribus Cassiae).2. The Papilionaceous genus Desmofischera Holth.(only species: D.monosperma Holth.) is reduced to a synonym of Monarthrocarpus Merr.[only species: M. securiformis (Benth.) Merr.]. Additional collections, from Morotai, are cited
