Variation in Potentilla sect. Aureae (Rosaceae) in the Baltic states

The morphological variation of four Baltic representatives of the genus Potentilla section Aurea–P. neumanniana, P. arenaria, P. subarenaria and P. crantzii was studied with multivariate methods. Altogether 41 characters were used. The most important characters for the phenetical classification are those of the epidermis: characters of stellate and glandular hairs and numbers of cells. Macromorphological characters are less important, the most useful of these being the length of sepals and stipules and the number of teeth of the central leaflet. All four species are significantly distinct. Even P. subarenaria, a putative hybrid of P. arenaria and P. neumanniana, is clearly separated. At the same time, the species are morphologically quite variable, and it is possible to distinguish subclusters (morphotypes) within P. neumanniana, P. subarenaria and P. crantzii, which are also statistically distinct. The varieties described by Wolf (1908) under the name P. verna (P. neumanniana) do not agree well with the morphs in our material. However, it can be admitted that var. typica and var. neumanniana axe prevalent, var. pseudo-incis? and var. incis? occur occasionally; only var. longifoli? can be quite clearly delimited.     

Carex dapanshanica sp. nov. (C. sect. Mitratae,Cyperaceae) from Zhejiang,China

Micromorphological photographs of the achenes of C. dapanshanica and C. chungii under SEM (scanning electron microscope) are provided as well.

It is related to S. monbeigii (Cardot) Balakr., but primarily differs in the number of styles (S. cibagouensis = 5; S. monbeigii = 4) and the shape of stipules and leaves (S. cibagouensis: stipules caducous, small, with entire margin, leaflets in 9–11 pairs; S. monbeigii: stipules persistent, large, serrate, leaflets in 6–8 (–10) pairs).     

Angelica muliensis sp. nov. (Apiaceae) from Sichuan,southwest China

Angelica muliensis (Apiaceae), a new species from Sichuan Province, southwest China, is described and illustrated. The new species resembles A. biserrata, but differs in the shapes of the leaflets and sheaths, umbel number and size and especially mericarp features.

Carex sinosupina sp. nov. (sect. Lamprochlaenae,Cyperaceae) from Gansu,north central China

Carex sinosupina, a new species from Gansu, China is described and illustrated. This species is similar to C. aridula and C. ivanoviae, but differs by having broader leaves, 2.0–3.5 mm wide, perigynia 3–5‐veined abaxially and achenes concave at the middle of one lateral surface. Based on a field survey and SEM (scanning electron microscope) observation of the micromorphology of perigynia and achenes, the morphology and micromorphology of the new species, C. aridula and C. ivanoviae is compared.
