Hakone´s Index for assessment of paphiopedilum alba Form (copyright)


1/- the base of the leaf axil : without red pigmentation = 10%
2/- Flower stem : without red pigmentation = 15%
3/- Hair on the flower stem : without red pigmentation = 15%
4/- Staminodes : without red pigmentation = 15%
5/- Labellum : without red pigmentation = 15%
6/- dorsal sepal : without red pigmentation = 10%
7/- Petal : without red pigmentation = 10%
8/- lateral sepal : without red pigmentation = 10%

add up = 100 % = plants with albinism genes


My definition for Alba forms: a plant whose flowers can be green, yellow or white , or a combination all three , but devoid of any red pigmentation.

 

[Hakone]

1/- the base of the leaf axil :no red pigmentation



2/- Flower stem: no red pigmentation


3/- Hair on the flower stem: no red pigmentation

 

[Hakone]

No red pigmentation


4/- Staminodes
5/- Labellum
6/- dorsal sepal
7/- Petal
8/- lateral sepal

 

[Hakone]

Example:

Paphiopedilum delenatii


1/- the base of the leaf axil : without red pigmentation = 10%



2/- Flower stem : without red pigmentation = 15%
3/- Hair on the flower stem : without red pigmentation = 15%

4/- Staminodes : without red pigmentation = 15%


5/- Labellum : without red pigmentation = 15%
6/- dorsal sepal : without red pigmentation = 10%
7/- Petal : without red pigmentation = 10%


8/- lateral sepal : without red pigmentation = 10%


add up :

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 10% + 15% + 15% + 15% + 15% + 10% + 10% + 10% = 100%

Thanks, I find this very informative.

 

[dodidoki]

It should be done a more sophisticated index than yours- wthat is otherwise correct-, because your index allow yellow pigment in flower, but aureum fma. is not real albino and there are a few species in wich case all two forms exist. (eg. helenae, bullenianum).

 

[Ozpaph]

good check list.
to summarize - all parts of the plant and flower must lack red pigmentation (anthocyanin).

 

[tim]

an arguably more interesting is what to call plants that are not 100% albinistic...what if the hairs on the stem are red - brown and everything else is albinistic...what would you call that? If the hairs are albinistic and there is some color on the base of the leaves would you call it the same thing as if it had brown hairs on the stem and no leaf pigmentation? There is an interesting and neofinetia-like chart or something to be made here...

 

[Hakone]

I have no experience with Neofinetia. I cultivate no Neofinetia. If the sum is not 100%, I call normal, no alba.

 

[tim]

So for example that nearly-albino exul that was recently posted, you would call normal? It is most definitely not normal...and definitely not truly alba...

 

[Hakone]

I would say normal . There is no exception.

 

[reivilos]

I don't really follow the purpose of the index.
Why not just have a look at the flower and see for ourselves?

As a side note, how much % do you grant to white foliage ?
I saw a paph. with 100% white foliage lately.

 

[Hakone]

white foliage have no significance.
e.g.purpuratum, sukhakulii, fowliei, callosum did not blossom white.

with the index can predict , whether the plant alba is.

Do you have alba forms of paphiopedilum ? Do you know what paphiopedilum alba form ?

 

[Hakone]

A Division paphiopedilum alba form costs about 2000 - 10000 USD. Do you really believe the dealer when you buy the plant from him, sometimes you hit him only once during the exhibition.

 

[reivilos]

I only buy from trustworthy dealers,
that saves further hassle.

Most alba forms are readily available
anyway (including the ones you
mentions) for much less than 2k$.
However, I won't risk a tigrinum or hangianum alba because:
1- it'll most probably be fake
2- I'll probably kill it - if it's authentic
3- (subjective) I won't spend that much
on a plant.

I think rare specimen should be
propagated first, by skillful growers -
which I'm not.

I'm looking for:

- purpuratum album
- Callosum album
- helenae album
- tranlienianum album
Do you have an offer ?

If the plant is not flowering, how can you recognize that the plant is possible an alba form .

I think your score system is correct, obviously if a plant (not flower) has no red pigment ( but regulary should have), this specimen suspect to be an alba form.

But there are few exeptions, so it is not sure. Eg. I bought I depigmented concolor from Mr. Popow, never bloomed yet so he sold it as concolor "green leaves", maybe will turn to alba.
