This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa.
Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales.
This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.
The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 3 contains accounts of 47 families, including those formerly included in the Leguminosae (Mimosaceae, Caesalpiniaceae, Fabaceae) as well as the large and important Rosaceae. Also included are those families formerly covered by the name Saxifragaceae (Saxifragaceae in the strict sense, Penthoraceae, Grossulariaceae, Parnassiaceae, Hydrangeaceae and Escalloniaceae).
Readers who loved Lola at the Library, Lola Loves Stories, and Lola Reads to Leo are in for a backyard treat. After Lola reads a book of garden poems, she wants to plant some flowers. She gets books from the library and chooses her plants. Then Lola and her mommy buy the seeds, make the garden, and mark the rows. Now it's time to wait. . . .
Little Flowers and Fiery Towers is a collection of poems and poetic prose in honor of St. Therese of Lisieux and St. Joan of Arc.

Martin in his other books. Here you may observe in your own quiet space its landscapes, flowers, and fiery towers with the celestial guidance of St. Therese and St. Joan!"
