Vuorela, I. & Lempiäinen, T. 1997: Palynology and palaeobotany of a cultural layer in the centre of Helsinki. — Ann. Bot. Fennici 34: 1–13.
A 45-cm thick cultural layer was analysed in the centre of the town of Helsinki. The microfossil data, comprising the results of pollen and charcoal particle analysis, were supplemented with plant macrofossil data. Together, these data reflect the local development from a closed forest to a rural community which, in the period AD 1640–1910, gradually grew into an urban settlement. The profile can be dated using old maps of Helsinki.
Kang, S. S. & Chung, M. G. 1997: Spatial genetic structure in populations of Chimaphila japonica and Pyrola japonica (Pyrolaceae). — Ann. Bot. Fennici 34: 15–20.
One hundred and forty and 100 individuals were mapped and sampled in a natural habitat (11 x 45 m) of Chimaphila japonica and Pyrola japonica, respectively, to analyze the spatial distribution of genotypes using spatial autocorrelation analysis of enzyme polymorphisms. Chimaphila japonica is a rhizomatous evergreen subshrub, whereas P. japonica is an evergreen herbaceous perennial. Populations of these species have discontinuous distributions and occur in conifer forests in northeastern Asia. For C. japonica, Moran’s I values were significant in 16 out of 40 (40%) cases, and for P. japonica, in 26 out of 50 (52%), indicating that a significant small-scale genetic substructuring within a population existed for both species. The mean correlograms of C. japonica and P. japonica indicate that the patch widths of both species were approximately 5–7 m and 9–10 m, respectively. A nonrandom distribution of genotypes may be a reflection of restricted gene flow, patchy establishment of genetically related individuals, and/or clonal reproduction. The pattern of the average Moran’s I values of C. japonica for each distance class was similar to that of P. japonica. The similar pattern of genetic substructuring found in both species reflects their similar life history and ecological traits (e.g., insect pollination, similar habitat and habit, seed dispersal mechanism, and low fecundity).

The phloroglucinol composition of Dryopteris subimpressa Loyal from North India has been investigated for the first time. This diploid sexual species contains almost exclusively propionyl (P) homologues of flavaspidic acid (5), aspidin (6), desaspidin (8) and trisdesaspidin (21). The following homologues have been isolated in crystalline form for the first time: aspidin PP (6-PP); desaspidin PP (8-PP); desaspidin AP/PA (8-AP/PA) and trisdesaspidin PBP (21-PBP). These preparations contain only minor amounts of acetyl (A) and butyryl (B) homologues as found by mass spectrometry (MS) and reductive degradation.
Cañas, M. S., Orellana, L. & Pignata, M. L. 1997: Chemical response of the lichens Parmotrema austrosinense and P. conferendum transplanted to urban and non-polluted environments. — Ann. Bot. Fennici 34: 27–34.
Thalli of the lichens Parmotrema austrosinense (Zahlbr.) Hale and P. conferendum Hale were taken from a non-polluted area and transplanted within this area, and to a downtown site in Córdoba, Argentina. Pigments, malondialdehyde, hydroperoxy-conjugated dienes and sulphur were measured after various exposure periods. Changes in the quantified compound concentrations were observed throughout the exposure period in both species and in both sites. In the urban site, however, chlorophyll concentration was lower and, in P. conferendum, malondialdehyde concentration was significatively higher. These results can be attributed to the effect of atmospheric pollutants on the transplanted lichens.
Guitián, J., Navarro, L., Guitián, P. & Sánchez, J. M. 1997: Variation in floral morphology and reproductive success in Petrocoptis grandiflora (Caryophyllaceae). — Ann. Bot. Fennici 34: 35–40.
We examined variation in the floral morphology of Petrocoptis grandiflora Rothm. (Caryophyllaceae), a plant endemic to the northwest Iberian Peninsula. First, we investigated whether peduncle length, calyx length and petal-limb length influence reproductive success (as measured by seed production). Second, we investigated whether floral morphology varies with position in the inflorescence and/or among the six populations studied. Peduncle length and calyx length showed no significant relationship with seed production; however, petal-limb length was significantly and positively correlated with the number of seeds produced by the flower. All three morphometric characters, and the number of ovules per ovary, varied significantly with position in the inflorescence, but not among populations.
Tan, K., Perdetzoglou, D. K. & Roussis, V. 1997: Biebersteinia orphanidis (Geraniaceae) from southern Greece. — Ann. Bot. Fennici 34: 41–45.
Biebersteinia orphanidis Boiss. (Geraniaceae) is the only European representative of a chiefly Asiatic genus comprising 5 species. It was long presumed extinct in its locus classicus on Mt. Killini (N Peloponnisos, Greece) but was recently discovered on a neighbouring mountain, Saitas. Flowering and fruiting material was collected and some of the aerial parts used for a preliminary analysis of essential oils. It was found that the quantity of aliphatic hydrocarbons was rather high (25.74%) and also that oxygenated sesquiterpenes were absent.
Enroth, J. 1997: Taxonomic position of Leptocladium and new synonymy in Chinese Amblystegiaceae (Bryopsida). — Ann. Bot. Fennici 34: 47–49.
Leptocladium sinense Broth., the single species of its genus and known only from type material from Yunnan, South China, is redescribed and illustrated with line drawings. It is transferred from the Thuidiaceae (original placement) to the Amblystegiaceae and considered closely related to Platydictya Berk. Amblystegiella yunnanensis Broth. is synonymized with Amblystegium serpens (Hedw.) B. S. G. and Amblystegium sinensi-subtile C. Müll. with Platydictya subtilis (Hedw.) Crum.
Piippo, S., He, X.-L. & Koponen, T. 1997: Hepatics from northwestern Sichuan, China, with a checklist of Sichuan hepatics. — Ann. Bot. Fennici 34: 51–63.
A collection of bryophytes by a Finnish-Chinese expedition in northwestern Sichuan in September 1991 includes 50 species of liverworts. The major collecting areas were in Minshan Range in Songpan and Nanping Counties. A smaller collection comes from the valley of the River Suo-Mo North of Qiong-Lai Range in Ma-Er-Kang County and from Hongyuan County from the vicinity of Shua-Jin Temple. Chiloscyphus itoanus (H. Inoue) Engel & Schust. is reported for the first time for China, and Calypogeia cordistipula (Steph.) Steph. is synonymized with C. neesiana (Mass. & Car.) K. Müll. Twenty-six liverworts are for the first time reported for Sichuan. The checklist of Sichuan hepatics is given. A total of 139 species are known to occur there. The flora is remarkably diversified. The major elements of the flora are widely distributed circumpolar boreal taxa, which occur in the humid oroboreal zone in Sichuan. Boreal species of the lichen genera Cladonia Hill and Peltigera Wild. and the species of the moss families Cinclidiaceae, Mniaceae and Plagiomniaceae show a similar altitudinal distribution in the study area. Species of widely distributed temperate southeast Asiatic taxa occur with an intermixture of some endemic and tropical species. The list includes discussions on the nomenclature, taxonomy, and distribution.

Pycnolejeunea surinamensis Steph. is transferred to Cheilolejeunea (Spruce) Schiffn. as C. surinamensis (Steph.) He; Rectolejeunea maxonii Evans is transferred to Lejeunea Libert as L. maxonii (Evans) He, and Pycnolejeunea miradorensis Steph. is synonymized with Lejeunea maxonii; Pycnolejeunea flagellifera S. Arnell is synonymized with Rectolejeunea berteroana (Gott.) Evans; and the status of Lejeunea novoguineensis Schiffn. and the genus Rectolejeunea Evans are reviewed. Complete descriptions and illustrations are provided.

The symbols for the compounds in CRFJ's material of D. wallichiana from Mexico and Hawai'i have changed places. The correct phloroglucinol composition should be exactly the same as that of CRFJ-13004-5, 14710-11 from Jamaica or the following:Norflavaspidic acid-AB (4-AB) (+), flavaspidic acid-BB (5-BB) (+), flavaspidic acid-AB (5-AB) +++, filixic acid-BBB (19-BBB) (+), filixic acid-ABA (19-ABA) (+), trisflavaspidic acid-BBB (23-BBB) (+) and trisflavaspidic acid-ABB (23-ABB) ++.
