In his paper on the genus Scolops (Kansas University Science Bulletin, Volume XVIII, page 417, 1928), Breakey comes to the conclusion that Scolops cockerelli Fowler is a synonym of Ball's Scolops robustus. On pages 427-428 he records the comparison of specimens of a number of closely related species with the type specimen of Fowler's species by Mr. W. E. China of the British Museum.

ABSTRACT Taxonomic and floristic studies in the state of Rio de Janeiro allowed the rediscovery of Miconia gigantea, an endemic species to the Atlantic Forest, until recently known only from the type specimen, collected over 100 years by A.F.M. Glaziou. We present an amended and detailed description of M. gigantea, providing characteristics of the flowers, fruits and seeds, in addition to illustrations, comments about taxonomic affinities with closely related species, the presently known distribution together with new occurrence records, and the conservation status.

The Brazilian porcupine was one of several species described and illustrated by the 17 th -century naturalist Georg Marcgrave, whose text was among the primary references upon which Linnaeus based his Hystrix prehensilis. As currently understood, Coendou prehensilis is a wide-ranging polytypic taxon that has never been revised and may represent a complex of closely related species. Given that no name-bearing type specimen of C. prehensilis is believed to be extant, and in order to avoid ambiguous application of this name, we designate a specimen collected at the type locality in Pernambuco, northeastern Brazil, as the neotype for Hystrix prehensilis Linnaeus. The geographic distribution of mitochondrial DNA haplotypes suggests that specimens from west-central Brazil previously identified as “Coendou prehensilis” belong to a different species, but only a comprehensive taxonomic revision of the genus will shed light on species limits and the geographic ranges of C. prehensilis and other congeneric forms.

Reference is made to Krøyer's description of the hermit crab, Pagurus pubescens, and to Stimpson's later description of P. krøyeri. Comparison of specimens of krøyeri with the type specimen of pubescens showed them to be identical. The American species thought by Stimpson to be pubescens and, therefore, left without a name, is now given a name, P. arcuatus. Both species are compared with P. trigonocheirus, and a new diagnostic character, the shape of the anterior division of the third sternite, is used.

The plant that was first called “Odontoglossum wyattianum” by Gurney Wilson was exhibited at a meeting of the Royal Horticultural Society on January 3, 1928. No official description was ever published and no type specimen was ever designated, or has surfaced, hence making this distinct species a taxonomic ‘ghost’. The taxonomic validation of Odontoglossum wyattianum is made here through the designation of a holotype, together with a diagnosis, a brief taxonomic history and comparison with similar and closely related species.

In my revision of the North American Eucosminae (Bull. 123. U. S. Nat. Museum, p. 172, 1923) I applied the generic name Exentera Grote to a small group of closely related species including improbana Walker (=cressoniana Clemens) and spoliana Clemens. I did this upon the assumption that, in the main, Fernald and others had correctly identified the Grote species. Although I had gone over the Fernald collection at Amherst, Mass., I did not see the Grote types, and assumed they were in the British Museum and so stated in the revision (p. 174).

Finger millet is a superior staple food for human beings. Microsatellite or Simple Sequence Repeat (SSR) marker is a powerful tool for genetic mapping, diversity analysis and plant breeding. In finger millet, microsatellites show a higher level of polymorphism than other molecular marker systems. The identification and development of microsatellite markers are extremely expensive and time-consuming. Only less than 50% of SSR markers have been developed from microsatellite sequences for finger millet. Therefore, it is important to transfer SSR markers developed for related species/genus to finger millet. Cross-genome transferability is the easiest and cheapest method to develop SSR markers. Many comparative mapping studies using microsatellite markers clearly revealed the presence of synteny within the genomes of closely related species/ genus. Sufficient homology exists among several crop plant genomes in the sequences flanking the SSR loci. Thus, the SSR markers are beneficial to amplify the target regions in the finger millet genome. Many SSR markers were used for the analysis of cross-genome amplification in various plants such as Setaria italica, Pennisetum glaucum, Oryza sativa, Triticum aestivum, Zea mays and Hordeum vulgare. However, there is very little information available about cross-genome amplification of these markers in finger millet. The only limited report is available for the utilization of cross-genome amplified microsatellite markers in genetic analysis, gene mapping and other applications in finger millet. This review highlights the importance and implication of microsatellite markers such as genomic SSR (gSSR) and Expressed Sequence Tag (EST)-SSR in cross-genome analysis in finger millet. Nowadays, crop improvement has been one of the major priority areas of research in agriculture. The genome assisted breeding and genetic engineering plays a very crucial role in enhancing crop productivity. The rapid advance in molecular marker technology is helpful for crop improvement. Therefore, this review will be very helpful to the researchers for understanding the importance and implication of SSR markers in closely related species.
