Costaceae - Wikipedia, the free encyclopedia Costaceae is a family of perennial herbs of the order Zingiberales. It is similar to the family Zigiberaceae, but differs in that the labellum of the flower is comprised of five staminodes instead of three, and the Costaceae contains no aromatic oils. The flowers are generally solitary or aggregated in inflorescences. www.wikipedia.org /wiki/Costaceae   (142 words)

NYBG.org: Chelsea Specht Profile The goal of my research is to examine the processes and patterns involved in the evolution and diversification of land plants, especially the monocotyledonous lineage. Further studies are focused on the floral development of the four composite floral morphologies found in Costaceae: melittophilous, ornithophilous, Cadalvena, and Tapeinochilos.

[No title]   (Site not responding. Last check: 2007-10-29) Costaceae presently consists of about 95 species which until recently were placed in four genera: Costus, Tapeinochilos, Dimerocostus, and Monocostus. Recent systematic and developmental studies have led to a novel understanding of evolution within the family and have resulted in the description of three new genera (Chamaecostus, Cheilocostus and Paracostus) to accommodate the phylogenetic diversity of the Costaceae.

Specht, Chelsea D.* and Dennis Wm. Stevenson.   (Site not responding. Last check: 2007-10-29) A recent phylogenetic study using molecular data for a representative taxonomic sampling of Costaceae has shown that revision of the taxonomy is necessary in order for the taxonomic groups to reflect phylogenetic results. In addition, it was shown that characters typically used to define "natural groups" within Costaceae are actually homoplasious, and their historical use to define taxonomic groups has resulted in the recognition of various polyphyletic genera and subgenera. The addition of a morphological dataset and an analysis of character evolution has revealed that while many of these composite characters are homoplasious, the individual characters that comprise them yield synapomorphies for monophyletic lineages. www.botany2002.org /section12/abstracts/16.shtml   (173 words)

Zingiberales Cannaceae + Marantaceae + Zingiberaceae + Costaceae: raphides 0; petiole with one series of air canals; guard cells with inner and outer ledges unequal; petiole short, poorly differentiated; C connate, both A whorls with two staminodes, adaxial A of inner whorl fertile; micropylar collar well developed, cells of exotesta longitudinally elongated; chalazosperm +, endosperm slight. Costaceae can be recognised even vegetatively: they have ligulate leaves with a closed sheath that are arranged in a single spiral up the stem. Their inflorescences are dense, spicate-capitate, and have large bracts, and their monosymmetric flowers have a large labellum and single stamen, the style running between the two halves of the large anther. www.mobot.org /MOBOT/Research/APweb/orders/zingiberalesweb.htm   (2438 words)

Specht, Chelsea D.* and Dennis W. Stevenson.   (Site not responding. Last check: 2007-10-29) The phylogenetic relationships of Costaceae, a tropical monocotyledonous family sister to the gingers (Zingiberaceae), were investigated with a combination of two chloroplast loci (trnLF and trnK) and one nuclear locus (ITS1 - 5.8s - ITS2). The resulting parsimony analysis of selected taxa which demonstrate the range of floral morphological variation in the family shows that the Caldavena-type floral morphology is ancestral to the group and that both Tapeinochilus species and a Monocostus + Dimerocostus clade represent recent divergences. This represents the first detailed investigation into intra-generic and intra-specific evolutionary relationships within the family Costaceae and presents some novel evolutionary trends with respect to floral morphology and biogeography. www.botany2001.org /section12/abstracts/148.shtml   (180 words)

A phylogeny for the genera in the family Costaceae is proposed based on a cladistic analysis using morphological and molecular data. The genus Tapeinochilos is placed in a basal position, the genera Costus, Dimerocostus and Monocostus group together in a clade with the terminal clade formed by Dimerocostus and Monocostus. www.nmnh.si.edu /rtp/students/1995/jaramillo.htm   (399 words)

www.TopTropicals.com - rare plants for home and garden Costus are easily distinguished from other commonly cultivated gingers because the leaves spiral around the main stem like a circular stairway. Sometimes Costus are still listed with other gingers in family Zingiberaceae, but generally they are accepted classified in a separate plant family, Costaceae, along with Dimerocostus, Monocostus and Tapeinochilos.

! Rainforest Ginger ! Tropical Rainforest, North Queensland Australia Both families (as well as the closely related families Cannaceae and Marantaceae) have flowers that are characterized by one main functional stamen, while the other four stamens have usually been modified into 'staminodes' which often act as attracting petals. While the latter family tends to have shorter, fatter spirally arranged leaves with a closed sheath on the main stem, the former has the classic long and large banana-like, aromatic and distichously arranged leaves, such as found in the true ginger (Larsen et al 1999). While the zingibers have their centre of diversity in Asia and Australia, the Costaceae are found mainly in Africa and South America (Larsen 1999). rainforest-australia.com /Rainforest_Ginger.htm   (369 words)

We explore this and other theoretical predictions of neutral theory and test them using a recently published phylogeny of family Costaceae in combination with extensive range data for the family, gathered from herbarium specimens and collections databases. Using empirical data from Costaceae, we examine the relationships between lineage age and range size, measure species richness in individual clades as a function of clade age, and compare these observations. abstracts.co.allenpress.com /pweb/esa2003/document?ID=26148   (279 words)
