A taxonomic revision of Plagiogyriaceae (Pteridophyta) Naturalis
Zhang, Xian-Chun; Nooteboom, H.P..
A taxonomic revision of Plagiogyriaceae is presented. One genus and 11 species are recognised. One species, P. egenolfioides, is subdivided into four varieties. Only one species, P. pectinata, occurs in the New World, all others in the Old World. One species, P. glauca, and one variety, P. egenolfioides var. decrescens, extend east to the S Pacific islands (Solomons).

Access to the crown of canopy trees Naturalis
Nooteboom, H.P..
Many botanists collecting in the tropical rainforest face the problem of collecting from the often very tall canopy trees. Not always will tree climbers be available and even if they are they cannot always climb all trees, especially after a rain, or when lianas or nearby smaller trees are absent. A method was designed by Donald R. Perry (Biotropica 10, 1978, 155- 157) and later discussed by Dr. E. Torquebiau (BIOTROP) who drew my attention to this method and used it himself.

Conservation Naturalis
Nooteboom, H.P..
Japanese fear to loose income. As result of Japan’s strategy to exhaust the Southeast Asian forests before turning to its own sizeable reserves of timber now most of the forest in the accessible areas is gone. Japan imports more wood than any other country in the world. In 1980 it bought 55% of all the round wood, sawn wood, and plywood traded in the world. It also takes 54% of all exports of tropical hardwood, 86% of which come from South and Southeast Asia. Japan takes the lion’s share of the exports from Indonesia, Malaysia, and the Philippines and a large proportion of the export from Thailand — which is nearly out of timber now — and Papua New Guinea. The Malaysian Department of Forestry forecasts that their remaining forests will be exhausted by...

CITES: In February 1987 Singapore finally ratified the Washington Treaty on the international trade in threatened species, exceptions have been made for the trade in crocodile products. A serious breach has now been closed that was of some impediment to the trade between Singapore and many of its partners. FAO’s Tropical Forestry Action Plan. (Unasylva 38, 1986) develops a strategy for action in five fields, among which conservation of tropical forest ecosystems.

Ctenolophonaceae Naturalis
Hooren, A.M.N. van; Nooteboom, H.P..
The systematic place of the tropical lowland rain-forest tree Ctenolophon OLIVER has a chequered history. Originally it was referred to affinity with Olacaceae (OLIVER, 1873; MASTERS, 1875; ENGLER, 1889; BAILLON, 1892) or Icacinaceae (BECCARI, 1877). HALLIER ƒ. (1912, 1918) held another view and arranged the genus in the Celastrales, deriving this group from Linaceae. HUTCHINSON (1959, 1973) referred the genus to the Malvales.
