Note on the plan for the Pteridophyte series of Flora Malesiana

Ferns are by far the largest division of vascular cryptogams, and, for purposes of publication of Flora Malesiana, they will have to be subdivided in a series of parts. This necessarily raises the problem of taxonomic subdivision of ferns into families or other major taxonomic units, a matter on which there is at present no general agreement among pteridologists, except that the more primitive families are generally recognized as distinct groups. As regards the majority of ferns therefore no formal arrangement into families will be attempted. There is however a fairly general agreement that certain groups of genera (e.g. the Davallia group) are natural groups. It is the intention to arrange the genera of ferns in such groups, and to publish the group-revisions in such sequence as may be most practicable. The author of the revision of any particular group must naturally decide the limits he will recognize for the group; and as the whole work will be by more than one author, some differences of opinion as to the delimitations of groups are probably unavoidable. It is believed that such differences of opinion will not be great, and if they occur their existence will be indicated by cross-references

Report of work on ferns carried out at Bogor 1957-1958

I spent the period from Oct. 8, 1957, to March 27, 1958, at Bogor, Indonesia. During that period I worked regularly in the Herbarium Bogoriense. The main part of my work consisted of a complete rearrangement of the fern herbarium, which consists of some 20,000- 30,000 specimens

An exchange of views on the Cyatheaceae

When Dr. R.E. Holttum kindly submitted the following essay review of two papers on Cyatheaceae, a suggestion that Dr. R.M. Tryon be enabled to reply was welcomed by both pteridologists. The editor feels grateful to them for their contribution. First Dr. R.E. Holttum: GASTONY, G.J. Spore morphology in the Cyatheaceae. I. The perine and sporangial capacity: General considerations. Amer. J. Bot. 61 (1974) 672-680. GASTONY, G.J. & R.M. TRYON. Ibid. II. The genera Lophosoria, Metaxyas Sphaeropteris, Alsophila and Nephelea. Amer. J. Bot. 63 (1976) 735-758
