Chung, M. Y. & Chung, M. G. 1999: Notes on spatial genetic structure in populations of Cymbidium goeringii (Orchidaceae). — Ann. Bot. Fennici 36: 161–164.
The fine-scale population genetic structure of Cymbidium goeringii Rchb. f. (Orchidaceae), a small herbaceous perennial, was analyzed using spatial autocorrelation statistics in a severely disturbed population (60 x 100 m area). All visible individuals (72) were sampled and their locations were mapped. Individual plants were genotyped for 14 allozyme loci, and Moran's spatial autocorrelation statistics were calculated for 19 alleles. The pattern of spatial genetic structuring is very weak in the population, though over 500 out of 598 individuals have been removed during the past two years by collectors. However, the average values show essentially no spatial autocorrelation, but there is some autocorrelation for some alleles. This indicates that mass collectings by human beings have not affected the genetic structure (thinning-like effect). The mean correlogram of the population suggest that total gene flow may be considerable. As pollen movement by bumblebees is leptokuretic, it is highly likely that large numbers of very small seeds travel through the population by wind.
García, M. A. 1999: Cuscuta subgenus Cuscuta (Convolvulaceae) in Ethiopia, with the description of a new species. — Ann. Bot. Fennici 36: 165–170.
As a result of a worldwide taxonomic revision of Cuscuta L. subgenus Cuscuta, C. castroviejoi M.A. García is described as a new species endemic to Ethiopia. The taxonomic status of some little known African species of the subgenus that appear in Ethiopia is discussed. Two previously recognized species of the subgenus, C. approximata Bab. and C. pedicellata Ledeb., are excluded for the country while C. pretoriana Yunck. and C. somaliensis Yunck. are recorded for the first time. A key to the species of the subgenus in Ethiopia is provided.
Marhold, K. & Ancev, M. E. 1999: Cardamine penzesii, a rediscovered taxon of the C. pratensis group (Cruciferae). — Ann. Bot. Fennici 36: 171–180.
Cardamine penzesii Ançev & Marhold nom. nov. (= C. tuberosa Pénzes & Vida nom. illeg., non DC.), previously known only from the type locality, was discovered at four other localities in the southern part of the Bulgarian Black Sea coast. In addition, it is shown that distribution data for C. pratensis L. var. dentata (Schult.) Wimm. & Grab. from Bulgaria and those for C. uliginosa M. Bieb. from the European Turkey are based entirely on the misidentification of C. penzesii. Three specimens of C. penzesii from the Asian Turkey represent the first records for the C. pratensis group for this area. The unique character of C. pen zesii seems to be the presence of globular tubers on the rhizomes. This taxon is also characterised by the white petals and by the appressed hairs on the rachis of leaves arising from adventitive buds and sometimes also on the rachis of leaves of young rosette leaves.
Marttila, O., Jantunen, J. & Saarinen, K. 1999: The status of semi-natural grasslands in the province of South Karelia, SE Finland. — Ann. Bot. Fennici 36: 181–186.
The semi-natural grasslands were inventoried in the province of South Karelia (Finland) in 1992, 1993 and 1996. Altogether 89 different sites were found, covering a total area of 97 hectares. The sites were classified into five different biotopes, which comprised a total of 115 grasslands. Three-quarters of all sites (68, 76%), covering an area of 65 hectares (67% of total), were assessed as being in danger of losing their value because of either poor management or lack of management. The results indicate that the area of semi-natural grasslands in the province is now about 250 times smaller (0.4%) than at the beginning of the 20th century. The status of these environments in South Karelia is alarming.

In two papers, of which this is the second, the authors present a macro- and microscopic study of 45 Myxomycetes collected on the Peninsula of Baja California, Mexico. This part treats 21 taxa, in alphabetical oder, from Hemitrichia clavata (Pers.) Rostaf. to Trichia varia (J. F. Gmelin) Pers. SEM photographs of spores and capillitial threads are provided. The following taxa are new to Mexico: Hemitrichia minor G. Lister, Licea biforis Morgan, L. variabilis Schrad., Physarum contextum (Pers.) Pers., P. viride var. aurantium (Pers.) Lister and P. viride var. incanum Lister. We propose the synonymy of Mucilago crustacea F. H. Wigg. var. crustacea and M. crustacea var. solida Sturgis. We also propose the following two new combination: Mucilago dictyospora (R. E. Fr.) Lizárraga, G. Moreno & Illana. Hemitrichia serpula (Scop.) Lister var. parviverrucospora Lizárraga, Illana & G. Moreno is described as new to science.
Sonck, C. E. 1999: New Taraxacum species from Greece. V. — Ann. Bot. Fennici 36: 211–217.
The paper describes six new species of Taraxacum L. from Greece: T. kalambakae Sonck, T. rigidifolium Sonck, T. sublimiforme Sonck, T. trigonense Sonck, T. zagorae Sonck (of sect. Vulgaria or Ruderalia), and T. microcranum Sonck (of sect. Erythrosperma). The species are illustrated in black and white photographs.
Zhu, R.-L. & So, M. L. 1999: Additions of Lejeuneaceae taxa to the hepatic flora of Yunnan, China. — Ann. Bot. Fennici 36: 219–229.
The present study reports 31 species new to Yunnan, including ten new to China: Acrolejeunea recurvata Gradst., Cheilolejeunea ventricosa (Schiffn.) X.-L. He, C. vittata (G. Hoffm.) R. M. Schust. & Kachroo, Cololejeunea serrulata Steph., C. yakusimensis (S. Hatt.) Mizut., Lejeunea alata Gottsche, L. infestans (Steph.) Mizut., L. neelgherriana Gottsche, L. obscura Mitt., and L. stevensiana (Steph.) Mizut. Male plants and perianths of L. subacuta Mitt. are reported and illustrated for the first time. Lejeunea cocoes Mitt. and Lejeunea tuberculosa Steph. are newly reported for Papua New Guinea and Indonesia, respectively.
