Arisaema 2016

[Gabriela]

A. taiwanense has a purple spathae and the spadix appendage is also different, very blunt.

Coincidentally the nystery Arisaema was found in a pot of A. taiwanense but was decidedly different including the corm itself.  We thought it might be consanguineum from a friend and from what Gabriela say that seems to be the logical identification.


thanks all,

Although they bloom at very different times is it possible that it could be a hybrid?

I think it is a simple case of a mix-up when planting the corms as it is now resembling other consanguineums from a friend.

Yesterday I decided it was time to identify two unlabelled very late Arisaemas.  Both identical in leaf, first no problem as first leaflet sticking straight up in the air so Arisaema consanguineum.  Second identical in leaf but in flower a twofor. Hiow does  A. 'Amorous Embrace' sound?

Picked up an "Arisaema speciosum" yesterday in the Annapolis Valley.  It was the only one showing any signs of growth in the nursery.  With the warmth here it started to unfurl overnight and looks to me like yet another consanguiseum with one solitary leaflet straight up in the air and many more to unfurl ruling out speciosum.  There's hope it has a dark flower from what little we can see.  I presume consang. is the only one that does the erect solitary leaf?

What a malformation in the double Arisaema John! I don't know if it will repeat next year; I had a trifoliate ciliatum which didn't.

And, no to the last question, ciliatum at least, also does the 'solitary leaf signal'. You'll see when it opens which one, seems to be a good purple colour.

Thanks Gabriela.  The doubling of the A. flower was likely a one time event and I would be very surprised if it repeats.  There must be something in the air around here as this Rhododendron dichroanthum ssp. apodectum I pollinated earlier this month was a double as well.

Last week I stopped by to check a place with a population of large &  A. triphyllum  specimens (leaflets more +/- 25  cm long); also good stems colour - first image.
I stumbled upon one plant with two lateral leaflets lobed – reminding of the A. triphyllum ssp. quinatum /A. quinatum).
Anyone else has seen/grows similar forms of A. triphyllum (with lobed leaflets)?

[Afloden]

I've seen forms of triphyllum with lobed leaflets, but they have never persisted in cultivation with the lobes. Quinatum is a very different plant that flowers nearly a full month after triphyllum from the same latitude and the spadix is tapered and curved.

[Gabriela]

Thanks Aaron, I know is not A. quinatum –  I've seen herbarium specimens on the Atlas of Florida Plants (if someone else is interested  there are also plant pictures) - http://florida.plantatlas.usf.edu/specimendetails.aspx?PlantID=670

I find it exciting to see variations in the wild – they keep open the possibility Surely some won’t come true from seeds but it doesn’t matter. After my posting, I found a herbarium specimen of A. triphyllum var. pusillum with the same lobed leaf – on the Virtual Herbarium of Chicago region. I have to check it in the spring when flowering.

I’m very grateful for the digitized herbarium projects available on-line today.

Yes it had a single erect leaflet upon unfurling but now I wonder if this could be a concinnum?


Atacama-like conditions here, less than 1.5" of rain since May and has been warm since the last week of June.

Can I have Mojave-like for Ontario then John?
The mouth margins are not recurved enough to be consanguineum, so you may be right! Congrats.
