Re: Dracontium ID please

---

Dear Bernhard,

How long was the spathe? Was it longer than 20 cm? I believe your plant could be Dracontium prancei. It typically has that sort of narrow quite straight spathe, barely opening, with a translucent area at the base and stipitate spadix. It is probably the most easy and free flowering species I know. Dracontium gigas would have a much larger spathe more around 60-80 cm long.

With best regards,

David

Aroiders, esp Tom and Christopher,

after a while I come back to my request via the aroid-L; Steve was so kind to help to look after the reason why my messages bounced all the time; it had to do with my email-adress and provider; so we decided that I reregister with another email-address...

Tom, if you maybe find time to look again at my plant, I'd be very thankful.

Meanwhile, I think, too, that is is not gigas; the new leaf is again about 2 m high and I guess gigas should be taller let alone that I growit in Germany under suboptimal conditions.

Kind regards,

Bernhard.

Tom and Christopher,
(I send this message to Steve and the aroid-L as well, let alone I am sure that it will not show up in the mailing list)

thanks for your replies and your announcement Tom of id-ing the plant when you are back from Alaska.

The key (or one key) to Dracontium is displayed here:
http://www.aroid.org/genera/dracontium/drackey.php
and the revision is available at:
https://www.researchgate.net/publication/288271650_Revision_of_Dracontium_Araceae

But I am not good in taxonomy, let alone that I have a horticultural background (apprenticeship in Ornamentals and later specialized in plant tissue culture), so I leave it to the experts...

BTW, the plant died back after the bloom and has grown a new leaf meanwhile that ist about 2 m high right now and unfurling the leaf.
My conditions are not those of an Bot Garden; it grows in a "wintergarten" with night temperatures of >19 °C; so suboptimal for gigas.
However, I know that a gigas leaf will grow much higher in good conditions; but maybe the height of my plant speaks against gigas already.
Still very curious to learn what spec. I grow.

Kind regards,
Bernhard.

Christopher & Bernard:  I don’t think that your plant is D. gigas. It has a much larger spathe that is rounded at the apex. I will try to key out this plant but can’t do it today because I leave for Alaska tomorrow.

 

Chris: I will try to send you the pdf of the Dracontium revision on One Drive but what is your email?

Beautiful plant.

 

I used to have a key to Dracontium . . . but I cannot seem to find it. It has been more than 15 years since I grew them; too long. If I can find it, I will see what I can do.

 

Happy days,

Christopher

Aroiders,

I'm posting this for Bernhard Strolka, while we sort out why he can't
post to Aroid-L himself. I believe he can still see posts to the lists,
so he should see your replies, but if not I'll forward them to him.

Aroiders,

I have a plant obtained as D. gigas, but I am not sure if this is really
a gigas.

Could you kindly have a look at the pictures displayed here (close ups
of the flower attached; pic of the leaf in the first link):

I asked Steve Jackson since I saw a D. gigas at the Cairns Bot Garden in
2016 where I met Steve; however, Steve has the impression that my plant
is not a D. gigas, but something different.

The leaf is about 2,20 m high.

Any ideas what I grow?

Kind regards,
Bernhard.
