A critical checklist of the Mesoamerican and South American species and hybrids of Blechnum is presented. For each entry the place of original publication, types, authors, and pertinent synonyms are included. Most of the synonyms are cited with their nomenclatural types. Information on geographical distribution and altitudinal range, ecology, as well as morphological and nomenclatural comments pertinent to the treated taxa are also included. Hybrids that have been cytologically and… 

A synopsis of the fern family Blechnaceae in Santa Catarina, Brazil: reviewing Sehnem’s 1968 flora

The fern family Blechnaceae in Santa Catarina, southern Brazil, is reviewed in order to update the work done by Sehnem in Flora Ilustrada Catarinense and to present descriptions and identification keys for the species.

Blechnum yungense (Pteridophyta, Blechnaceae), una Nueva Especie de Argentina y Bolivia

Resumen Una nueva especie Blechnum yungense Ramos Giacosa (Pteridophyta, Blechnaceae), la cual se distribuye en Argentina y Bolivia se describe e ilustra a partir de material de Jujuy, Argentina.

[Arborescent species of the genus Blechnum (Blechnaceae: Pteridophyta)].

The presence of B. tabulare in America is confirmed, and the taxonomy of the species is updated, since external and internal morphology indicated that other related, American and African species, such as B. spannagelii and B. madagascariense must be included under that name.

Estudios morfológicos y taxonómicos en Blechnum (Blechnaceae-Pteridophyta): B. tabulare y B. magellanicum

Habit of plants, type of rhizome, rhizomatic scales, mucilage glands, and type of ornamentation of the perispore are characters shared by the two species, while the other traits vary at the specific level, allowing them to be identified as two separate taxa.

Revisión de especies monomórficas y subdimórficas del género "Blechnum" ("Blechnaceae-Polypodiophyta")

Se actualiza la descripcion de los taxones, su nomenclatura, tipos, sinonimia, distribucion geografica y ecologia, se proponen dos combinaciones nuevas (B. australe subsp. hastatum y B. austrobrasilianum) y se da una clave para su determinacion.


Blechnum malacothrix , hasta el momento conocida solo de Peru y Bolivia, se registra por primera vez para el noroeste de Argentina. Con este hallazgo el numero de especies de la familia Blechnaceae

Morphology of the sporophyte and gametophyte of the swamp fern, Blechnum serrulatum (Blechnaceae, Pteridophyta)

A revised, comprehensive description of the sporophyte and gametophyte of the swamp fern, Blechnum serrulatum Rich.

Biometrics of the sporangia and spores of the Parablechnum cordatum complex (Blechnaceae, Polypodiopsida)

A biometric analysis of sporangia and spores, important taxonomic structures in the distinction of ferns, has been carried out and statistically supported taxonomic significance and are therefore useful for species separation.

Estudios epidérmicos en helechos y licófitas medicinales de la Provincia de Córdoba, Argentina

An epidermal analysis of vegetative and reproductive organs of 28 medicinal ferns from Cordoba Province (Argentina) has been carried out. The objectives were: a) to characterize in detail the

Biometry of stomata in Blechnum species (Blechnaceae) with some taxonomic and ecological implications for the ferns.

Stomatal length and width showed a very high correlation, suggesting an endogenous, genetic control, thus giving these traits a considerable diagnostic utility, and significant statistical relationships between altitude and stomatal index are found.

A cytological survey of the Pteridophyte flora of Jamaica found several genera have been cytologically examined for the first time and their phylogeny has been discussed in the light of these findings.

Morphological studies on some species of blechnum, doodia, woodwardia and stenochlaena. I. The gametophytes and the juvenile sporophytes

The mature prothallus is of the cordate type, reaching maturity in about 8 weeks from spore germination, but often continuing growth for long and sometimes elongating markedly with age, the same species often exhibiting a fair amount of plasticity in developmental history.

Chromosome counts for Mexican ferns

Chromosome numbers for 106 species in 36 genera of Mexican ferns are reported, and 47 are first reports for the species, suggesting taxa where additional sampling might aid in making taxonomic decisions.

Determination of tocopherols in vegetable oils

A rapid (ten minute) and selective method for measuring individual tocopherols found in vegetable oils has been developed using High Performance Liquid Chromatography (HPLC) with ultraviolet

Effects of Microwave Energy on the Tocopherols of Soybean Seeds

The effects of microwave heating on the tocopherols of soybeans were studied in relation to chemical changes in the lipids. The amounts of α-, β-, γ-, and δ-tocopherols in the soybeans before

Effects of Microwave Heating and Gamma Irradiation on Phytate and Phospholipid Contents of Soybean (Glycine max. L.)

The effect of microwave heating and gamma irradiation treatments on phosphorus compounds of soybean seeds were studied. Inorganic phosphorus was significantly (P < 0.05) increased while, phytate and

Reversion problems in edible fats.

Lipids in margarines and margarine-like foods

The lipid composition of margarines from stores in selected locations in the U.S. is reported. The lipids determined include the fatty acids, tocopherols and major plant sterols. Data are included

Stability of chlorophylls and carotenoids in sweet potato leaves during microwave cooking

Each cooking treatment was conducted at 2450 MHz with an output power of 700 W for 0, 2, 4, or 8 min in duplicate. The various chlorophylls and carotenoids were analyzed by high-performance liquid

Effects of thermal oxidation on the constitution of butterfat, butterfat fractions and certain vegetable oils

To evaluate the thermal oxidative behavior of butterfat in comparison to selected vegetable oils, samples of winter and summer butterfat, liquid and solid butterfat fractions, and selected vegetable
