Bednarek-Ochyra, H. & Ochyra, R. 2000: Racomitrium norrisii sp. nova (Grimmiaceae, Bryopsida), endemic of western North America. — Ann. Bot. Fennici 37: 235–241.
Racomitrium norrisii Bedn.-Ochyra & Ochyra (Grimmiaceae, Bryopsida) is described as a new species of subgen. Cataracta Vilh. and sect. Stenotrichum (Chev.) Bedn.-Ochyra, and its diagnostic features are illustrated. It is closely related to the European R. hespericum Sérgio, Muñoz & Ochyra from the Iberian Peninsula from which it differs in its leaves with bistratose marginal border of (1–)2–10(–13) rows of cells extending from the base to the apex; unistratose laminae in the upper part; shorter, 9–12-celled axillary hairs; and lacking or inconspicous papillae over the cell walls. Racomitrium norrisii is a hydrophytic moss endemic to western North America where it occurs in California and Idaho.
Chung, M. G. & Park, C.-W. 2000: Notes on spatial genetic structure in a hybrid population between Aconitum japonicum subsp. napiforme and A. jaluense (Ranunculaceae). — Ann. Bot. Fennici 37: 243–247.
The fine-scale genetic structure in a hybrid population (35 x 55-m area) between the herbaceous perennials Aconitum japonicum Thunb. ex Murray subsp. napiforme (Lév. & Vaniot) and A. jaluense Komarov (Ranunculaceae) was analyzed using spatial autocorrelation statistics. Although individuals of the population have protandrous flowers, the population is highly structured. Individual genotypes exhibited significant spatial autocorrelation on a scale of 4 m due to the limited seed and pollen dispersal, which is consistent with a neighborhood size of about 25. Such neighborhood sizes are about one-fourth of the entire population.
Álvarez Fernández, I. & Nieto Feliner, G. 2000: A new species of Doronicum (Asteraceae, Senecioneae) from central China. — Ann. Bot. Fennici 37: 249–253.
The name Doronicum thibetanum Cavill. has been inadvertently applied in herbarium labels to designate a species distributed in central China (provinces of Gansu and Sichuan). However, the study of the type specimen reveals that it is actually a species of Aster. The central Asian species of Doronicum has no available name and is thus here described as D. cavillieri Álv. Fern. & Nieto Fel. This new species has as its closest relatives five central Asian species: D. altaicum Pall., D. briquetii Cavill., D. falconeri C.B. Clarke, D. kamaonense (DC.) Álv. Fern. and D. stenoglossum Maxim. Their morphological affinities and phylogenetic relationships are commented upon and an identification key is provided.
Kotiranta, H. & Saarenoksa, R. 2000: Three new species of Hyphodontia (Corticiaceae). — Ann. Bot. Fennici 37: 255–278.
Three new species of Hyphodontia J. Erikss., H. borealis Kotir. & Saarenoksa, H. erastii Saarenoksa & Kotir. and H. tuberculata Kotir. & Saarenoksa are described. The first one is characterised by small, white aculei, thin-walled hyphae, narrow, sting-like cystidia and wide apical hyphae of aculei. Hyphodontia tuberculata is yellowish, tuberculate, has fairly thin-walled hyphae, bears long, thin-walled hyphoid cystidia and gloeocystidia. Hyphodontia erastii is closely related to H. sambuci (Pers.) J. Erikss., but has mostly smaller capitate cystidia and subcylindrical spores. Species resembling the new species are described and illustrated, and a key to the species treated is given.

Two new species of the genus Pseudoliparis Finet (Orchidaceae) from New Guinea are described and illustrated: P. gregorii Marg. & Szlach. and P. cruciatis Marg. & Szlach. Two new combinations within this genus are proposed: P. balabacensis (Ames) Marg. & Szlach. and P. latipetala (J. J. Sm.) Marg. & Szlach.

Murguía, M. & Villaseñor, J. L. 2000: Estimating the quality of the records used in quantitative biogeography with presence–absence matrices. — Ann. Bot. Fennici 37: 289–296.
We propose two new methods to estimate the error associated with data in presence–absence matrices commonly used in quantitative biogeographic analyses. The first is based on the estimated richness as compared with the known richness; the second is based on presence–absence frequencies addition in the data matrix. We propose an approach to integrate both criteria by using an index that determines the quality of the records as specified in the data matrix for each geographic region. It is assumed that the errors more commonly associated with the scoring of the biodiversity are those related to the absence of records in the subregions. On the other hand, it is also assumed that those mistakes caused by the scoring of elements in areas where they are not found are minimal. We propose to relate the quality of the records to the level of resolution or precision of the biogeographical analysis, assuming that the lower resolution of the analysis, the better the quality of the records. When a presence–absence data matrix is reordered, considering larger subregions and respectively a lower number of them, the possibility of errors due to lack of records of elements diminishes. This situation can be viewed as a particular case of the so-called modifiable areal unit problem (MAUP) of the geographic information systems.
