| This paper is a preliminary account of investigations on species of Campylopus, mainly from the high Andes of Colombia and from adjacent regions. The studies are based on herbarium specimens, field studies and cultural experiments. The genus Campylopus was founded by Bridel (1819) on the basis of a curved seta only and included, therefore, species of Grimmia and other genera. Later he modified his earlier circumscription (Bridel 1826) so that the genus then contained (except for one uncertain species) only species of Campylopus as known today. A subdivision of the genus was made by Limpricht (1886) based on the structure of the costa as seen in cross section: Pseudocampylopus Costa without stereids, ventral layer of large cells, other cells containing... |

| During my studies of the Surinam specimens belonging to this genus my attention was drawn to the often wrong interpretation of several old species. To avoid future misidentifications it seems useful to give a short review of the American species that are known up till now. It is emphasized, however, that this paper does not have the pretension to be a monograph of the American species. For the greater part my study of the species was confined to the type material and the variability therefore is not known. However, this contribution may serve as a base for a future monograph of this interesting group. Attention is drawn to the fact that only older leaves of the plants should be studied, because the leaf apex of the younger leaves is in all species acute... |

| The variability of Papillaria nigrescens has already been emphasized by STEERE (1934) and BARTRAM (1949). Even in the type specimen (S-PA) I found form and areolation of the leaves to be variable (fig. 1). This type material, moreover, proved to be provided with some filiform microphyllous branchlets, which is all the more noteworthy as the presence of microphyllous branchlets has sometimes been regarded as a diagnostic character of P. appressa. I examined a specimen sent to me on loan by the Munich Herbarium; it has been labelled in an old handwriting: “Hypn. appressum Hrsch. Minas Geraes” and in pencil was added: “Neckera appressa CM v. Muell. II, 136”; some distance apart from this was written: “An C. Müller”. I suppose that this must be the type... |

| Eén van de grote giften van A. A. Pulle, Lanjouw’s voorganger als Hoogleraar in de Bijzondere Plantkunde en de Plantengeographie te Utrecht, was zijn goede keus van medewerkers. Hij kon die keus maken dank zij een andere gift, die van leermeester. Pulle’s stimulerende activiteit als hoogleraar luidde de wedergeboorte in van de Nederlandse plantensystematiek door een stroom van leerlingen waarvan er velen ook nu nog een belangrijke rol spelen in de botanische wereld. Vele van Pulle’s leerlingen uit de eerste tijd moesten Utrecht verlaten omdat er in de twintiger jaren nu eenmaal nog geen sprake was van een redelijk gesalariëerde wetenschappelijke staf. Eén leerling echter werd zo gefascineerd door de vele mogelijkheden die het Utrechtse instituut bood, dat... |

| The Netherlands Antilles comprise the islands Aruba, Curaçao and Bonaire of the Leeward Group, and St. Eustatius, Saba and the southern part of St. Martin (St. Maarten) of the Windward Group. The northern part of St. Martin belongs to the French territory (Departement de la Guadeloupe). Botanical investigations were started already in the 18th century, but it was not before 1909 that an enumeration of the vascular plants of part of the Netherlands Antilles appeared in print (Boldingh, 1909; the other part appeared in 1914). In 1913 Boldingh published a Flora of the Netherlands Antilles (in Dutch). Brother M. Arnoldo published a Flora of Curaçao, Aruba and Bonaire (in Dutch, 1954; second edition 1964). An elaborate study of the vegetation of the islands was... |

| A survey of the literature in which species of Musci are reported for Colombia, amplified by unpublished identifications of recent collections, indicates a known flora of 750 species. About 600 published names are treated as synonyms. An annotated list of the collectors is also provided, as well as notes on critical localities and itineraries, especially those of Purdie, Lindig and Wallis. Moss collections of Moritz, Wagner and Osculati are not from Colombia. Two new combinations are proposed: Campylopus pittieri Williams var. congestum (Thér.) comb. nov. and C. pittieri var. latilimbatum (Thér.) comb. nov. |
