Description: Since the completion of Radlkofer’s monumental work on the Sapindaceae in Engler’s series “Das Pflanzenreich” 50 years have now elapsed, almost 40 since its publication. It is still the basis of virtually all taxonomic studies in the family. Some of the gerontogean genera have since been the subject of revisional work (Leenhouts 1969, 1971), but for the neogean representatives there are only some regional treatments (e.g. Rambo 1952; Barkley 1957; Reitz 1962; Soukup 1969), apart from descriptions of new taxa scattered through the literature. When studying the taxa native to Suriname in connection with the preparation of a supplement to the family treatment published previously in the “Flora of Suriname” (Uittien 1937) it soon became apparent to me that the genus Talisia was particularly incompletely known when Uittien published his account of the family, actually not much more than an extract from Radlkofer’s work. The number of species known or to be expected from Suriname proved to have doubled; this is not due to inadequateness of Uittien’s work but to much more extensive collecting. Two of the species met with since could not be identified with any species dealt with by Radlkofer or described after his time: these are described as new below. In order to establish that they were truly undescribed the descriptions and, where possible, types and/or other authentic specimens of all species described after Radlkofer were checked. A list of these follows; it may serve as a kind of bibliographic supplement to Radlkofer’s monograph. The two species marked with an asterisk have been posthumously listed in the supplement to his work.

Description: In a forthcoming publication (Kramer, in prep.) floristic and taxonomic data of the pteridophyte flora of Suriname will be assembled, with keys and notes on their local distribution and ecological preference. The present paper deals with the geographical distribution of Suriname pteridophytes beyond the boundaries of Suriname (Fig. 2), a subject that lies beyond the scope of a local fern Flora. In the past, some (but relatively not very many) authors of fern Floras included a paragraph on the distribution of the taxa (Posthumus, 1928; Christensen, 1932; Backer & Posthumus, 1939). In some other fern Floras some space is devoted to ecology, but very little to geography (Holttum, 1954). In still others, considerations of a general kind on ecology and geography are altogether lacking (Vareschi, 1969). Lyell (1870), in his rather little-known book on the distribution of ferns, tried to bring together all the data known at his time; his work is now, of course, almost exclusively of historical significance.

Description: In the spring of 1968 and 1969 the two senior authors visited the Maltese Islands of Malta and Gozo and collected and photographed plants. The entire herbarium collection amounts to about 350 numbers. The first set is deposited in the herbarium of the State University of Utrecht; duplicates were sent chiefly to the herbarium of the Royal Botanic Gardens, Edinburgh. Critical determination of the material yielded some results which may be interesting from a floristictaxonomic viewpoint and are therefore reported below. Beside herbarium material fruits and seeds were collected; the samples that germinated were investigated cytotaxonomically by the two junior authors. The results are also presented in the following. The first truly comprehensive account of the flora of the Maltese Islands is by Sommier & Caruana Gatto (1912-1915); it includes also the lower cryptogams. The older literature is also reviewed there. It is fairly complete and, for its time, taxonomically reasonably up to date. Then the Maltese botanist J. Borġ published his “Descriptive flora of the Maltese Islands” (1927), dealing only with vascular plants. This flora, on the other hand, was taxonomically antiquated even when it was published, reflecting the state of knowledge of plant taxonomy of some decades earlier, and therefore nomenclaturally also very much out of date. Since that time Malta has had very little attention in the botanical literature. Some notes or brief paragraphs are devoted to its flora in such general books as Adamović’s “Die pflanzengeographische Stellung und Gliederung Italiens” (1933) and Rikli’s “Das Pflanzenkleid der Mittelmeerlander” (2nd ed. 1943-48). In 1960 Lanfranco published his “Guide to the flora of Malta with 300 illustrations”. The plants included in it are a rather arbitrary selection from Borġ’s flora, whose nomenclature is also uncritically followed. A modern flora, with keys, is lacking.

Description: The present paper is the third regional revision of the Old World Lindsaeoid ferns. The second (the fourth in the entire series on the Old World Lindsaeoids) will be published as vol. II, 1 part 3 of Flora Malesiana; it is awaiting publication as the present paper goes to the press. Species fully described there and extending into the area covered by the present revision are not dealt with at length again, in order to avoid redundance. The present treatment deals with the species of Micronesia, Melanesia, and Polynesia, or, more precisely, the smaller Pacific Islands from the Palau Islands, the Marianas, and the Bismarck Archipelago in the West to Hawaii and the Marquesas in the East. The Volcano and Bonin Islands wil be treated with Japan, to which country they were recently returned; the Admiralty Islands are included in Flora Malesiana; New Zealand will be dealt with together with Australia; New Caledonia was the subject of a separate publication (Kramer 1967); no Lindsaeoid ferns have so far been found on the Tuamotus, Pitcairn, Easter Island, and other islands in the extreme East of Polynesia, nor on any atoll islands.
