Looks like it's going to have good color in the petals!

 

[SlipperKing]

Double flowered? Impressive. Not commonly seen in collections and even less blooming!

Will love to see it fully pen. Looking good.

ditto

I'll post a pic once it's fully open.

Lovely. How big is plant?

 

[bulolo]

It's about a 6 to 7 inch leaf span. The flower has been open about a week. I wonder if the pouch will inflate more?

 

[DrLeslieEe]

That’s quite an inflated lip already. I think it’s at its max. We awarded a jackii albescent form this past weekend with a more ovate (or narrower) lip with the same leaf span as first bloom seedling.

Is there any hard rule to separate P. jackii from P. malipoense?

Is there any hard rule to separate P. jackii from P. malipoense?

yes, talk to a splitter (not a lumper)

 

[BrucherT]

I think of malipoense as rounder-petaled and with less dark veins in the petals. Also, isn’t the fragrance distinctive? I don’t grow it, just stared at a lot of them.

Is there any hard rule to separate P. jackii from P. malipoense?

They are clearly different from each other.
-malipoense have very dark green thick leaves (2 to 3 times thicker than jackii), very rough leaf texture (if you run your hand on it, it feels like sand paper, raised veins, trapezoid staminode with dark purple at staminode tip. The flower's pouch has a translucent thin quality that one can see through it all of the spots on the pouch's inside face.
-jackii have thin leaves and lighter green , smooth leaf texture , no raised veins, staminode more square with very light streaks. The pouch is more opaque .
You certainly can tell the difference even without flower

here are the two photos of jackii leaves, make sure you click for translation to english,
the caption under the 1st photo said "Leaf surface of Paph. Jackii"
the caption under the 2nd photo said "The base of the back of the leaves of the Paph. Jackii lacks the purple-red spots unique to the Paph. Malipoense"

Thank you Hien and BrucherT! Always wondered about that.
