A New Species

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.

Campanula oreodoxa (Campanulaceae) is described and illustrated as a new sub-alpine species from North Khorassan province, Iran. The new species belongs to C. sect. Oreocodon based on dehiscence of the capsules with three middle pores at the base and absence of appendages between the calyx lobes. It is compared morphologically with the closely related species including C. hystricula and C. lourica. The micromorphological characters of seed coat and pollen grains of the new species are presented and compared with the chasmophytic allies in the area. Notes on distribution, habitat characterization, and the associated flora are provided. The new species is assessed as critically endangered (CR) and the conservation value of the habitats in the area is discussed.

Micromorphological Characters

New localities of <em>Hygrocybe salicis-herbaceae</em> were observed during the research on the fungi of the alpine zone in the Carpathians. This is the first record of this arctic-alpine fungus in the South-Eastern Carpathians. Macro- and micromorphological characters of the Carpathian collections are compared with the descriptions from other regions. A revision of literature data indicates that the sites in the Parâng Mts. reported here are the only known localities of the species from the entire Carpathian range.

In this study, morphological and anatomical data (including fruit micromorphological characters) of the genus Fuernrohria were studied and compared with the related genera Grammosciadium, Caropodium and Vinogradovia. The morphological description of Fuernrohria setifolia, which is the only known species in the genus, is expanded. Photos of inflorescences, infructescences and leaves of the species taken from the wild are provided. Leaf segment and mericarps are illustrated, and also the distribution area of the genus is mapped. Anatomical features of root, stem, leaf sheath, leaf segment and fruit are presented with photographs of cross sections for each of them. Vegetative anatomical characteristics of the species and micromorphological description of fruit are given and exhibited for the first time in the present study. The results show that two important diagnostic characters for Fuernrohria are determined for the first time as “shape and size of commissural vittae in mericarps” and “number of vascular bundles in leaf cross section”.

A New Species

Two species of Xanthagaricus discovered in Hubei Province of China are described based on the macro- and micromorphological features. Their identity is further supported by molecular analysis of the internal transcribed spacer (ITS) of the ribosomal RNA gene. The phylogeny obtained here showed that one of the Chinese species is nested in an exclusive clade which in combination with its striking morphological features, infers that it represents a new species, named X. ianthinus, while the other species is placed as a member in the X. epipastus clade. Descriptions are accompanied with illustrations of macro- and micromorphological characters and a discussion of related taxa is presented.

Diagnostic Importance

As micromorphological knowledge was not available for Coix aquatica Roxb., the foliar epidermal studies were carried out for Coix lacryma-jobi L. and Coix aquatica Roxb. with the aim of determining the patterns of variation in their epidermal characteristics and assessing their value in species identification. Comparative foliar analysis was carried out by using light microscopy, after following routine scraping method. The characters of diagnostic importance in the identification of C. aquatica are the sparsely distributed prickle hairs with long pointed apex in the abaxial epidermis and dumbbell shaped silica cells in both the epidermises. The diagnostic characters for C. lacryma-jobi are the cross shaped silica cells and dumbbell shaped on the abaxial and adaxial epidermis respectively. The observed differences in certain micromorphological characters helps in identification of presently studied two species of Coix.
