1) Definition of terms:
    A. a picture showing adventitious roots, glands, curled leaves,
       flower parts, etc

    B. discuss the typical terms used to describe ping habits,
       and what they mean (i.e. emarginate, rolled, lanceolate?)

2) Discussion of species organized by leaf/growth type:

    A. Tropical homophyllous (simplest case)
	i) characteristics 
	    I) flowers twice a year
	    II) continuous growth
	ii)
	    I) examples
		a) European: P. lusitanica
		b) Mexican: P. agnata
		c) Southern US: PP. lutea, planifolia, primuliflora
	    II) cultivation (media, dormancy, light, water, temps)
 		a) Peat/perlite for North American,
		b) vermic/perlite for Mexican.
		c) Bring examples of the fine & coarse vermiculite, plus
		   maybe a small cup of decent peat.

    B. Tropical heterophyllous (next simplest, adds another leaf types)
	i) characteristics
	    I) flowers twice a year
	    II) two different leaf types in summer/winter
	ii)
	    I) examples
		a) calciphilious: gypsicola, heterophylla
		b) calciphobic: P. colimensis, cyclosecta, ehlersia,
		   esseriana, moranensis, rotundiflora, zecheri
		c) Discuss that there is some argument about whether
		   soil pH matters, or if the reports are even accurate?
	    II) cultivation (media, dormancy, light, water, temps)
		a) calciphilous likes high pH (limestone, gypsum, etc)
		b) calciphobic like acid media

    C. Temperate homophyllous (introduces hybernacs)
	i) characteristics
	    I) flowers once a year 
	    II) forms hybernacula
	ii)
	    I) examples
		a) P. alpina, grandiflora, macrocera, vulgaris
	    II) cultivation (media, dormancy, light, water, temps)

    D. Temperate heterophyllous (most complex, hybernacs, two leaf types)
	i) characteristics
	    I) flowers once a year 
	    II) forms hybernacula
	    III) two different leaf types
	ii)
	    I) examples
		a) P. longifolia, vallisnerifolia.
	    II) cultivation (media, dormancy, light, water, temps)

    E. Common hybrids in cultivation
	i) P. x Sethos, x `George Sergeant', ehlersia x gypsicola

3) Propagation:

    A. leaf cuttings demo (10 min.)
    B. seed
    C. quick tissue culture overview (2 min.)

4) Miscellaneous cultural

    A. fertilization
	i) miracid spritz
	ii) Jurg Steiger recommends dilute egg white spray twice a year

    B. Pests
	i) fungus gnats
	ii) aphids
	iii) slugs
	iv) root rot


--------------------------

Perhaps 3) and 4) should go before the "blow by blow"?

I'm thinking that section 2) will be continously illustrated by slides.

We would only talk about species that we have photos of.

It would also be nice to have photos of your "under the tank" growing
setup just to have a slide of a typical growth setup.  We could also
photo my greenhouse bench, and floor setup, plus your work setup for
variety. 

Do you know a book that has a good illustration for 1) A,B. that we
could redraw or make into a slide?

	We have to think how we're going to present the slides.
	We probably want to present them all at once, after the
	discussion, co-incident with explaining what they are
	examples of.  I.e. first we briefly go over the types,
	which I'd imagine people will think is somewhat dry
	so we should proceed quickly.  Issue the handouts at
	this point.  Then do the slides, discussing what they
	show in relationship to the earlier discussion.  Then
	turn the lights on and do part 3 & 4 above to finish up.
