FloraBase (http://www.calm.wa.gov.au/science/florabase.html), maintained by the Western Australian Herbarium, includes brief descriptions, specimen lists and maps of all 12,500 vascular plant species occuring in this state. This represents ca half of the continent's flora and covers ca one third of its area. For each species an information page can be retrieved on-line comprising its scientific and common names, an indication of its status (native, alien, priority if threatened), a description, a map and (if available) a composite colour photograph showing habitat, habit, floral and fruit characteristics. Form-based query tools enable one to retrieve information or identify species on the basis of nomenclatural, geographic and/or morphological fields. There are also facilities for users to suggest corrections (eg redeterminations) to the various databases which underlie FloraBase. Over the coming months FloraBase will be extended to include highly detailed descriptions of genera and families. Over the horizon, the descriptive data will be expanded by use of a much larger character set. Another Australian botanical information system that may be worth your attention is The National Herbarium of New South Wales' PlantNet site (http://plantnet.rbgsyd.gov.au/). The HISCOM site (http://www.rbgsyd.gov.au/HISCOM/default.htm) provides a springboard for those embarking on a virtual foray in search of the Australian flora.

Flowers, unlike flat leaves and linear stems, are essentially 3D structures. This means that one can rarelly see all the significant features on a single flat image. Also equal but differently orientated organs (like petals) will appear unequal. Also there is possible confusion beetwen an individual flower and an inflorescence (gathering of small flowers, like the clover). The color is often not a discriminating character, since it can vary within a single species. <br>A typical flower is composed, from bottom to top, of 5 rings (or verticillas) of pieces attached on a vertical axis: <ul> <li> bracts</li> <li> sepals</li> <li> petals</li> <li> etamins (male part)</li> <li> carpels (female part)</li> </ul> Any of those 5 verticillas can be missing, or be joined within a verticilla or with the next one. The number of pieces in a verticilla can be beetwin 1 and several tens, 5 being a frequent number. <p>Leaves also have discriminating characters, and are (generally) 2D. These characters are: <br>- shape <br>- veins (better seen on the underside) <br>- differents types of hairs, better distinguished by touch or by lenses <br>- sometimes color <p>So you see, plant images are a challenge for a 2D general purpose image system. <h3> Bibliography on plant morphology</h3> If you want to read more, or just see images, here are some good books I use on general botany: <p>In french: <ul> <li> Précis de botanique - 2. végétaux supérieurs; Gaussen, Leroy, Ozenda, éditions Masson</li> <li> La botanique redécouverte; Aline Reynal, éditions Belin 1995</li> <li> Les plantes à fleurs - Guide morphologique illustré; Adrian D. Bell, éditions Masson</li> </ul> In english: <ul> <li> Plant form - An illustrated Guide to flowering plant morphology; Adrian D. Bell, at Oxford Un. Press</li> </ul> <h3> Image generation</h3> <h4> L-Systems</h4> There is a classic book on L-Systems applied to modelize plant growth 2 years ago (Prusinkiewicz, P. and Lindenmayer, A.,1990, The Algorithmic Beauty of Plants, Springer Verlag), and there is a French Institute called Cirad which does this sort of things for plants (they are on WWW but I haven't seen pictures). Here are some links,  having a wealth of information and links to other sites: <br> <a href="http://www.ctpm.uq.edu.au/virtualplants/ipiwww.html">http://www.ctpm.uq.edu.au/virtualplants/ipiwww.html</a> <br><a href="http://www.cpsc.ucalgary.ca/projects/bmv/software.html">http://www.cpsc.ucalgary.ca/projects/bmv/software.html</a> <p><a NAME="image_chain"></a>Of course L-Systems is a link in the chain we envision: <ul> <li> 2 or 3 pictures from different angles --></li> <li> 3D representation (with Bezier mappings or whatever) --></li> <li> pattern recognition --> L-Systems --></li> <li> static or growth simulation images</li> </ul> Sure this is a too big picture for now! <p>So we can enter L-Systems models in the database. I see the following advantages to this representation: <ul> <li> L-Systems capture truly biological features, like branching angles,</li> <li> species in the same genus or family will share a lot of growth patterns,</li> <li> this is a way to generate very accurate images with very little information.</li> </ul> I want to know more on this subject, especially are there many downloadable plants available, with a rigourous taxonomic identity ? <p>What is not clear now to me (this is not an urgent issue) is: <br>Will we develop, or is there, a XML vocabulary for L-Systems, or will a L-System definition remain "just" a character string. <br>The avantage of a XML vocabulary would be to have a unified syntax, from which a non-graphical processor could extract information of taxonomic relevance. From a XML representation, it is easy to generate a standart L-System definition, using a XSLT stylesheet. <h3> 3D recognition</h3> Here is a <a href="http://cermics.enpc.fr/~keriven/home.html">home page</a> about stereoscopic and other algorithms for extracting 3D information out of 2D images. We currently try to learn more about stereoscopic systems, especially for shapes having edges and folds. <p>I'm currently evaluating free downloads, notably Geometra. The demo I saw in their site is a house, having sharp edges; the user must click on  2 or more points in the 2D pictures, before 3D information is computed. <p>The next stage in our project would be to generate from the 3D facets a compact, non proprietary, preferably XML, clean <a href="3Dgeometry.htm">definition for complex 3D geometry</a> in the form of reunions and intersections of volumes defined by equations: <p>f(x,y,z)>=0 <p>and (e.g. NURBS and Beziers patches) surfaces defined by 3 functions R2 ---> R3 <p>(u,v) ---> (X(u,v),Y(u,v),Z(u,v)) <p>But this "next stage" is probably still a research subject. But this should not prevent us from gathering pictures from different angles, and generate 3D information out of it. </body> </html> --------------F0DEFDB499A8369AE40C44BD Content-Type: text/html; charset=us-ascii; name="ApplicationSpec.htm" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="ApplicationSpec.htm" <!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <meta name="Author" content="jmv"> <meta name="GENERATOR" content="Mozilla/4.5 [fr]C-CCK-MCD {FREE} (Win95; I) [Netscape]"> <title>Specimen identification specification</title> </head> <body> <center> <h2> Specimen identification</h2></center> This is a beginning of specification for an application, that could be a browser extension, realizing a Specimen identification.

On the other hand, the classical identification keys of Floras are tree-structured, and take in account only a kew characters. <p>There will be an input field for a character with three ways of entering organ, property, and value: <ul> <li> automatic completion in an input field</li> <li> point and click on an image of a schematic plant with all organs present (with a possibility to supress organs that are not present)</li> <li> pull-down menu</li> </ul> <p><br>This is possible because the relevant meta-data has been downloaded from server: list of organs, properties, and values (see <a href="XMLprotocol.htm">XML protocol</a>). <p>At any stage the following items are recomputed and proposed to the user: <ul> <li> the number of species corresponding to the list of characters entered</li> <li> the most discriminating questions</li> <li> the list of possible families or genus, possibly presented as a tree view</li> </ul> When the identification is advanced enough, the system will display an identikit picture (portrait-robot) of the plant or flower or leaf, that will be recomputed at each step. </body> </html> --------------F0DEFDB499A8369AE40C44BD--
