  Spermatophyte   (Site not responding. Last check: 2007-11-05)
The spermatophytes (Also called seed plants or Phanerogam) comprise those plants that reproduces by means of seeds not spores.
Spermatophyte have a reproductive cycle which develops pollen that results in seeds containing the embryo of a new plant.
Spermatophytes are included in the embryophytes or land plants, which also includes various groups that reproduce by spores, such as mosses, liverworts, hornworts, and ferns.

As there has been no justification for their actions, and as both Dr. Werner Greuter had copies of my complete database providing justifications as to why each name was considered correct, there was no reason for anyone to claim ignorance insofar as not having access to the basic information.
As I understand it, although the disagreement is still not fully resolved, the Spermatophyte Committee is considering the proposals at the present time.
Therefore, I ask that the members of the Spermatophyte Committee be keenly aware that there may be reasons other than those given by me for a specific rejection.

Most spermatophyte family treatments were contributed by J. Francis Macbride in Volume 13, with a series of parts and numbers.
The exceptions to this in the Spermatophytes are the families Orchidaceae in Volumes 30 and 33 and the Asteraceae, published by tribe in the New Series.
The index for Spermatophytes was adapted from that by Douglas C. Daly, [Brittonia 32(4): 1980, pp.

Among the spermatophyte plants, what are the advantages and disadvantages of sexual and asexual reproduction?
On separate paper, sketch the basic alternation of generations sexual life cycle practiced by the spermatophyte plants.
Show appropriate stages in both the gametophyte and sporophyte generations; chromosomal conditions of included stages; where meiotic cell division occurs in the cycle; where mitotic divisions occur in the cycle; and identify both sporophyte and gametophyte parental stages.

 Introduction to the Seed Plants   (Site not responding. Last check: 2007-11-05)
The spermatophytes, which means "seed plants", are some of the most important organisms on Earth.
Life on land as we know it is shaped largely by the activities of seed plants.
The other major group of seed-plants are the flowering plants, including plants whose flowers are showy, but also many plants with reduced flowers, such as the oaks, grasses, and palms.

 The Nature Conservancy in China - Northern Gaoligong Mountain Range
Because of its abundant precipitation, appropriate microclimate, and huge elevation span, the Northern Gaoligong Mountain Range project area has been identified as an unusual miniature museum of biodiversity.
It is roughly estimated that some 3,500 species of plant, including spermatophyte, fern and macro-fungi occur in the resort of intact old-growth forest.
Specifically, the Gongshan project area is home to about 55 endangered or rare seed plants and a total of 318 plant species found nowhere else on Earth.

Excerpted from a description by Roger Smith, "MSB is a collaborative international effort initiated by the Royal Botanic Gardens, Kew.
It seeks to collect and conserve seeds of 10% of the world's spermatophyte flora by the year 2010.
The necessary seed research will also be conducted to ensure the overwhelming majority of the banked species will survive for at least 200 years and can be germinated at will.

With the help of various bioinformatic tools (e.g.
Vicogenta: Katari, 2002; P-Gnome: Sarkar et al., 2002), I plan to use common seed plant sequences in concatenation to generate phylogenetic hypotheses that, together, may provide new and useful insights into Spermatophyte phylogeny.
Phylogenomics approaches are also being attempted as a way to infer orthology and protein domain evolution.
