Arisaema ident help

[Slug Killer]

Hi, hope someone can help with identifying the following two Arisaema. They were given to me by a friend who moved away recently who got them mixed up with lots of others he had. The first (two photo's) has grown very tall compared to the second. Any ideas?

I would guess Arisaema costatum for the first, and A lobatum for the last.  Could you post more pictures of the leaves later?

As soon as they are fully open I'll post some more pics then. Thanks for your help.

Next time, please could you possibly reduce the size of your pix to less than 800 pixels wide by 600 pixels height, so we don't have to scroll down.  It makes it easier to see the whole picture on one screen.  Thanks!
I look forward to seeing more pictures.

I've been told now that this could be Arisaema engleri.

[Diane Clement]

Dave, these same pictures have been posted on Arisaema-L identification pages (perhaps you sent them in?)  To complete the story here, Guy Gusman has identified them as A engleri and A lobatum.

Hi Diane, yes it was me who sent the pictures to Arisaema L, I found the site afterwards. Someone from Holland (Arno) contacted me and has been very helpful regarding ident. As you can see in the photo, there are several engleri in one pot. One has decided to go off sideways instead of up and is now skimming the ground and about a foot and a half long. Do you think this is because they are too close together or is there another explanation. Thanks in advance for any help.

Maybe the sideways one was planted sideways, not necessarily deliberately, but perhaps moved when the compost was being put on top?

[Slug Killer]

Hi, no that's not the case as they all originally start off coming up straight and then go sideways when in growth. I'll put a photo on later when I can remember my password for photobucket!

This photo was taken a week ago. It's now gone further and turned upside down. Seems to be searching for something

[Lesley Cox]

Mine do that when the seed heads are developing, just a matter of weight taking them down, on a weakening stem, but they don't do it while still in full flower. Maybe you should give lots of love and kisses. It seems to be suffering from an inferiority complex. What would it do if planted out in the garden instead of potted?

Is it still firm at the base of the pseudostem. It looks as if it is having a collapse.  Have the leaves developed as much on this as on the others.

Root aphids can do a lot of damage around the top of the tuber(actual stem).

Usually the fruiting issue only starts as the spathe withers.

[Slug Killer]

Hi all, it did not collapse but went that way from the start. The base is firm and no sign of any problems there but the leaves have not opened and don't look like they will. I only grow in pots for the first year, mainly getting correct identification before putting in the garden. There is another doing the same thing.
