Taxonomy of someDiploschistes spp. (lichenized ascomycetes,Thelotremataceae) containing gyrophoric acid

Three species which contain both gyrophoric and lecanoric acids and possess perithecioid ascomata are recognized in the genusDiploschistes. D. badius andD. gyrophoricus are described as new, whileD. subcupreus is reduced to synonymy withD. sticticus. Two species occur in the southern hemisphere, whileD. badius is found in N. America.     

Reproductive biology of the genusDamasonium (Alismataceae)

The reproductive biology of the genusDamasonium was studied in cultivation and in nature. A correlation was shown between flowering time and latitude. All species are self-compatible but the N. American member of the genus (D. californicum) is strongly protandrous and probably experiences high levels of outcrossing in nature. In the European taxa the stamens and the stigmas mature simultaneously but the levels of inbreeding appear to be greater in the southern species (D. bourgeai, D. polyspermum) than in the northern (tetraploid) speciesD. alisma. The Australian memberD. minus resembles the southern European species in being strongly autogamous and bud-pollination was shown to occur. Floral morphology, stigma exertion, pollen/ovule (P/O) ratio and seed weight each show a strong correlation with the degree of autogamy. Vegetative reproduction occurs only inD. californicum andD. alisma through the production of corm-buds. This study suggests that autogamy inDamasonium is accompanied by a shift in resource allocation from male (pollen) toward female (seed) function. However, further studies are required to assess the quality of seeds and their survivorship in nature.     

Revision ofDoniophyton (Compositae, Barnadesioideae)

This revision describes, illustrates and documents morphological variation inDoniophyton (Compositae, Barnadesioideae), restricted to Argentina and Chile. Two species are recognized,D. anomalum andD. weddellii (sp. nova), possessing distinct morphological and chromosomal features, elevational tolerances, and nearly allopatric distributions.Doniophyton weddellii occurs primarily in central to northern Andean Chile and Argentina from 1900–4000 m a. s. l.;D. anomalum is found principally in centralwestern Argentina and south into Patagonia at 0–1800 m a. s. l. Close relationship exists withChuquiraga of subfam.Barnadesioideae. It is hypothesized thatDoniophyton evolved out ofChuquiraga in the high central Andes between Chile and Argentina. It is suggested thatD. weddellii differentiated first, correlating with an aneuploid chromosomal decrease from n = 27 (inChuquiraga) to n = 25. Further evolution and chromosomal decrease to n = 24 resulted inD. anomalum, with accompanying migration into southern Andes and Patagonia. Nomenclatural changes result from examination of protologues and type specimens:Doniophyton anomalum replaces the commonly used nameD. patagonicum, and a new species,D. weddellii, is described for the taxon masquerading under the routinely used superfluous nameD. andicola. This paper is dedicated with admiration and respect to emer.

Sequence analyses of the ITS regions and the matK gene for determining phylogenetic relationships of Diospyros kaki (persimmon) with other wild Diospyros (Ebenaceae) species

To elucidate the relationships among Diospyros kaki and species closely related in previous studies, the nuclear ribosomal internal transcribed spacer (ITS) DNA sequence and the chloroplast matK gene were sequenced and compared with those of nine Diospyros species from Thailand, four species from temperate regions, and one species of southern Africa, D. lycioides. Maximum parsimony, maximum likelihood, and neighbor joining analyses of the matK and ITS data sets revealed that D. kaki is closely related to two diploid species, D. oleifera and D. glandulosa. D. kaki, D. glandulosa, and D. oleifera were placed differently in the trees obtained from ITS and matK data sets, suggesting that hybridization and/or introgression may have occurred during the development of these species. D. kaki was not found to be closely related to D. ehretioides, a diploid species from Thailand. These results differed from a prior analysis of this genus performed with chloroplast DNA (cpDNA) restriction site mutations in 3.2- and 2.1-kb amplified sequences. The results supported Ng’s hypothesis that D. glandulosa and D. kaki may share a common ancestor. D. oleifera was also closely associated with D. kaki.
