Molecular Breeding of Forage Crops: Proceedings of the 2nd International Symposium, Molecular Breeding of Forage Crops, Lorne and Hamilton, Victoria, ... 19-24, 2000 (Developments in Plant Breeding)

Forage plant breeding has entered the genome era. This timely book reviews the latest advances in the development and application of molecular technologies which supplement conventional breeding efforts for our major forage crops. It describes the plethora of new technologies and tools now available for high-throughput gene discovery, genome-wide gene expression analysis, production of transgenic plants, genome analysis and marker-assisted selection as applied to forage plants. Detailed accounts are presented of current and future opportunities for innovative applications of these molecular tools and technologies in the identification, functional characterisation, and use of valuable genes in forage production systems and beyond. This book represents a valuable resource for plant breeders, geneticists, and molecular biologists, and will be of particular relevance to advanced undergraduates, postgraduates, and researchers with an interest in forage legumes and grasses.

Sedum adolphi 'Golden Glow' - Calandstr, Leiden, NL 1 Aug 2010 01 Leo

Sedum adolphi 'Golden Glow' - Calandstr, Leiden, NL 1 Aug 2010 01 Leo

I've been wondering if the Sedum nussbaumerianum ('copper') I bought was not mis-I.D.ed and actually S. adolphi* ('golden')... Turns out it's both; these two names are synonyms!

If they are synonyms, S. adolphi is the older name, from 1912, so it takes precedence; Sedum nussbaumerianum was described in 1923.

Both plants were described in different German botanical gardens from plants grown from seeds collected in 1907 in (Veracruz) Mexico, by the great German plant explorer of Mexico; Karl Albert Purpus (1851–1941). Thus, in Europe (Germany) plants labelled as both S. adolphi and S. nussbaumerianum had been growing since the 1920's. By 1938 plants known under both species names were cultivated in Ithaca, New York; and had been obtained via the horticultural trade. The first record of S. nussbaumerianum in Spain is in 'Catalogus Seminum in Hortus Botanico Universitatis Valentinae anno 1953 Collectorum'.

The original description of S. adolphi only reported that the species was grown from seed collected by Purpus in Mexico; lacking a precise collection locale; it seems that this taxon became shrouded in mystery as time went by. Neither species was ever found in the wild again, and Purpus's collection locale reported for S. nussbaumerianum by Bitter in 1923 was never found.

According to Clausen [1959, 1975], in the horticultural trade in the USA in the 1950's S. adolphi & S. nussbaumerianum were often confused; both were often sold as S. adolphi, despite being what he considered S. nussbaumerianum. Also according to Clausen, cultivated plants of S. nussbaumerianum were all so similar he thought they might all belong to a single clone. According to San Marcos Growers, all such plants cultivated in California were known by the name S. adolphi (which they mistakenly believe is an incorrect synonym) since at least 1944, however, certain intergeneric hybrids with S. nussbaumerianum were recorded as being made by Californian nurseries in the late 1940's, so it seems that at least some people in California were growing plants labelled as S. nussbaumerianum since that time.
According to Robert Clausen in 'Sedum of the Trans-Mexican Volcanic Belt: an Exposition of Taxonomic Methods' in 1959 in the USA, S. adolphi was considered the species with larger, longer, thicker, broader, redder leaves prominently dorsally carinate (keeled), unknown from the wild, whereas the green, smaller S. nussbaumerianum was only known from Purpus's lost collection locale and was never seen in the wild by anyone except the deceased Purpus. Besides leaf size and shape, Clausen also thought inflorescence characteristics (the pattern in which flowers open on the inflorescence, shape of inflorescence, petal width) were key features diagnostic in separating the two species; although his characters here have been described as 'vague' by Chazaro-Basanez et al. [2010]. As pointed out by Bischofberger [2010] the description Clausen gives is significantly different than the original plant described by Hamet in the 'Notizblatt des Koniglichen botanischen Gartens und Museums zu Berlin' of 1912; this publication also contains an illustration -which shows that the leaves are not really carinate dorsally, but rounded, so it seems very likely that Clausen never read it. It would seem that all subsequent authors (Evans [1983], Stephenson [1991, 1994, 2002 (ed.2)], 't Hart & Bleij [2003]) used Clausen's leaf descriptions as a basis for describing S. adolphi. According to the Sedum Society the original form of S. adolphi as described by Hamet has now disappeared from collections.
In 1975 'Sedum of North America North of the Mexican Plateau' by Clausen was published. In this book Clausen seems to say much the same he said in 1959 regarding the two species; this is of note, because all the primary research done for this had been preformed in the late 1930's, almost 40 years earlier!
In 1978 S. nussbaumerianum was rediscovered in the wild in two different sites near those of Purpus in central Veracruz by Charles H. Uhl of Cornell University in Ithaca, New York and Felipe Otero (collection number: Uhl2497), although this rediscovery itself also seems to have been a confused affair. Uhl made no herbarium sheets or observational records, and seems not to have published anything about this, but he did take some cuttings back home with him to New York; The New York Botanical Garden received plants from him in 1983 (accession number: 135/83), and Huntington Botanic Garden received his plants around this time as well (HBG40419). In 1986 Huntington Botanic Garden sold Uhl's plants in their International Succulent Introductions program (ISI1682), described as the first S. nussbaumerianum re-introduction into horticulture. Nonetheless, it is clear that in Mexico itself none of the then current Mexi

Inside of the crown. This shade loving species produce flowers even inside the crown.

Yabu-Tubaki, ??, Japanese camellia, Camellia japonica, As this is understory species, widely distribute under warm temperate evergreen forest, typically of evergreen oaks, this tree looks beautiful rather under the cloudy sky,

In order to endure the winter low temperature leaves have thick glossy layer which shines beautifully under dim forest bed of evergreen big trees.

As this is so much typical and common in warm temperate zone in Japan, in German plant sociology, this zone is named "Yabu-tsubaki class", assigning this species as index species.

As ornamental flower tree, this species is one of the most important mother species of cultivated camellia. Yabu-tsubaki means, literary "bush camellia", which shows this species habitat well and also as gene, it shows 'wild camellia".

Seed oil is very good for cosmetic use with excellent quality. It is interesting that in the west, olive is commonly utilized, and olive has similar ecotype of leaves, evergreen with thick gloss layer. The difference is the layer is for enduring draught, on the other hand that of camellia is against cold weather.

As camellia oil has not industrialized, so oil price is very much expensive, then it rarely used for foods. I once tasted "tempura", fried with camellia oil. It tasted very good.

It is hard for me to stop once I begin to talk on this wonderful tree, so, I determine to stop here. Thanks for reading if there is such wonderful guest! (^_^)

Aquarium Plants

Translated from the popular 1999 revised German edition, this text describes the temperature, water, fertilizer, and light needs of more than 300 aquarium plants. Artificial lighting - lamp types, color temperatures, and mounting - is discussed in detail and the author provides advice on choosing the right plants for an aquarium. Ecological factors, flower biology and morphology, and reproduction methods receive detailed coverage. The book contains 525 color photographs with nearly all plants depicted with fully developed submerged foliage. Many of the photographs of rare plants were published for the first time in the German edition. Botanists as well as professional and amateur aquarium keepers will find this book indispensable.
