New national and regional bryophyte records, 48

Andreaea rothii has been recorded for the first time in Croatia. It is a boreo-temperate suboceanic species (Hill et al., 2007) relatively rare in SE Europe, since it is known only from Romania (Ellis et al., 2014d), Slovenia and Serbia (Sabovljevic´ et al., 2008 ; Hodgetts, 2015). The species was found in the Papuk Mountains, situated in the mainly lowland area of NE Croatia. In this region Papuk is the largest and highest mountain range, with peaks between 800 and 900 m a.s.l. They are characterized by high geological diversity dominated by metamorphic rocks, such as different types of schists, as well as granites. The climate is temperate, moderately warm without an explicit dry period. About 60% of the almost totally forested area is covered by different communities of beech forests. The well-developed black patches of A. rothii cover an area ca 2 m× 0.5 m on a steep north-facing cliff on the edge of an acidothermophilic sessile oak (Quercus petraea agg.) forest. The specimens of A. rothii grew on the bare rock with the following bryophyte species: Cynodontium polycarpon (Hedw.) Schimp., Dicranella heteromalla (Hedw.) Schimp., Dicranum scoparium Hedw., Polytrichum piliferum Schreb. ex Hedw. and Rhabdoweisia (cf.) fugax (Hedw.) Bruch & Schimp. The population is very small with an extremely high risk of extinction, therefore we propose CR as Red List status for the taxon in Croatia. According to the last checklist of the moss flora of Croatia (Sabovljevic´, 2006), only Andreaea rupestris Hedw., collected from just one locality in 1927 (Horvat, 1932 and ZA), was reported for the genus. The locality is very interesting from the point of view of the vegetation of Croatia, because it is within 100 m of the second stand of Fagus sylvatica L.-Sphagnum quinquefarium (Braithw.) Warnst. forest (Alegro et al., 2015). The second occurrence of Dicranum spurium Hedw. (Ellis et al., 2014d) and Rhabdoweisia fugax (Papp et al., 2013) in Croatia are also found here. Another interesting moss is S. capillifolium (Ehrh.) Hedw., that forms small red patches within the thick carpets of S. quinquefarium under the open oulder scree forest in the neighbourhood.

Liverworts New to Ecuador with Description of Plagiochila priceana sp. nov. and Syzygiella burghardtii sp. nov.

Abstract Based on our ongoing studies of the bryophyte flora of Ecuador we report fifteen liverwort species new to the country: Cheilolejeunea ornata, Drepanolejeunea integribracteata, Frullania lindenbergii, Kymatocalyx rhizomatica, Lejeunea corynantha, Leptoscyphus cleefii, L. spectabilis, Plagiochila bicuspidata, P. cuatrecasii, P. priceana, Radula xalapensis, Symphyogyna trivittata, Syzygiella burghardtii, S. contigua and S. trigonifolia. Notes are provided on the distribution, habitat and taxonomic differentiation of the species. Plagiochila priceana and Syzygiella burghardtii are new to science and Plagiochila inouei is a new synonym of P. bicuspidata. Keys are presented to northern Andean species of Leptoscyphus and Syzygiella.

A second locality for the critically endangered Colura irrorata (Lejeuneaceae) in the Ecuadorian Andes

Colura irrorata (Spruce) Heinrichs, Y.Yu, A.Schäf.Verw. & Pócs (5Myriocolea irrorata Spruce) (Lejeuneaceae) (Figure 1) is a very rare rheophytic liverwort of Ecuador, being known from only one locality (Gradstein et al., 2004; Yandún Vela, 2007; León-Yánez, 2008). The species was originally described in the monospecific genus Myriocolea Spruce and was transferred to Colura on molecular grounds (Heinrichs et al., 2012). Colura irrorata occurs between 1200–1700 m on the Topo river, a tributary of the Pastaza river in the Ecuadorian Andes, where it is most abundant between 1400– 1600 m, forming large populations of hundreds of individuals. The species grows almost exclusively on the small woody subshrub Cuphea bombonasae Sprague (Lythraceae) very near to the torrential water currents, together with three other rare rheophytic species, Lejeunea topoensis Gradst. & E.Reiner and Myriocoleopsis gymnocolea (Spruce) E.Reiner & Gradst. from Ecuador and SE Brazil, and Sematophyllum steyermarkii Bartram from Ecuador and a few localities in Central America (Gradstein & Reiner-Drehwald, 2007; Gradstein et al., 2011). The occurrence of this unique rheophytic bryophyte community along the Topo river correlates with some unusual features of the river distinguishing it from most other rivers in Ecuador, viz. its granite watershed and its rather flat valley bottom with a very low gradient (Gradstein et al., 2004).

Essential Oil Constituents of Mosses Species from Ecuador

Abstract Breutelia tomentosa (Sw. ex Brid.) A. Jaeger, Leptodontium viticulosoides (P. Beauv.) Wijk & Margad., Macromitrium perreflexum Steere, Campylopus richardii Brid., Rhacocarpus purpurascens (Brid.) Paris., and Thuidium peruvianum Mitt. essential oils were obtained by hydrodistillation. Using gas chromatography/flame ionization detector (GC/FID) and Gas chromatography/Mass spectrometry (GC/MS), a total of ninety four constituents were identified, representing for 80.5 93.8 % of the chemical composition. The major components were epizonarene (8.7 %) and α-selinene (6.7 %) in the oil of B. tomentosa, β-selinene (13.5 %) and α-selinene (10.5 %) in the oil of L. viticulosoides, selina-3,11-dien-6-α-ol (19.7 %) and curcuphenol (10.6 %) in the oil of M. perreflexum, epi-α-muurulol (15.1 %) and α-cadinol (12.5 %) in the oil of C. richardii. α-cadinol (36.8 %) and α-santalene (8.4 %) in the oil of R. purpurascens, and phytol (21.7 %) and valerenol (10.1 %) in the oil of T. peruvianum.
