We used to call this "dry birth", forgive the graffic description...I saw it
on other anthuriums that I used to grow at MoBot years ago and know the
condition you've described is common among anthurium growers. High constant
humidity, especially at the crown of the plant (with good air circulation)
helps keep the cataphylls moist and the newest leaf soft and succulent for
its emergence into the cruel cold world of the greenhouse.
AnthuraSelecties in the Netherlands are wonderful growers of anthurium (also
Eucagenera in Ecuador) so maybe check out their web sites or email them for
On the other hand, if the "spot" is a result of a fungal problem, send a
leaf sample to your state agriculture agency and they can test it. Keep us

Subject: [aroid-l] Cultivation of Anthurium Warocqueanum ?
I have been working with the growing of the Anthurium warocqueanum and A.
veitchii for a while - and have had reasonably good luck establishing an
acceptable greenhouse environment here in the Houston area (so far). I have
a number of plants to work with (thanks to many of you) and have had good
new growth after the acclimation period. But I do have a persistent anomaly
that I am hoping that some of you experienced growers might be able to help
me with. The warocq's develop nice new sizable leaves pretty consistently -
but frequently as the new leaf "unfurls" - or "opens" there is a significant
weakness in small areas of leaf tissue between the veins - and this weakness
develops into a translucent spot that soon develops into a complete
perforation - sometimes quite small 2 to 4 mm in diameter - and of course
the result is a permanent "blemish" -- and on a few occasions the fault in
the new growth is near the main rib and after "opening', the new leaf has a
And now my question is what causes this problem - which has been pretty
consistent over the past few months ?? Might it be a nutrition deficiency -
a watering problem - a greenhouse environment problem like humidity or
temperature range/variation or what ??
The problem is only associated with the warocq.'s - the veitchii's new
growth (in the same environment) has been excellent with numerous nice large
perfect leaves - very rewarding !!
I understand that diagnosis via e-mail is very difficult - especially with
so many variables - but I was thinking that some of you may have had similar
experiences -- and if so your help and advise will be greatly appreciated !!
This experience has been most frustrating - since success has been so close
but yet so far !
Many thanks, Harold Beck
