Jack in the Pulpit, Wallich’s Cobra Lily;   
In the griffithii/ propinquum alliance the spathe blade often remains intact for quite a while after pollination but in costatum it withers after pollination. The infructescence of costatum is much more dense with entirely green and rounder berries. Example of a costatum fruit for comparison can be found here: http://www.keepingitgreennursery.com/blogs/news/4232812-a-flowers-ugly-step-sister-seeds

Berries of the griffithii/ propinquum alliance often have longitudinal veins present that are either whitish (as on this plant) or black and the berries are mostly upward facing & more separated from each other than in costatum (there is more space in between them).

Cobra Lily from Uttarakhand : 4 posts by 4 authors. Attachments (1)

Last night I m back from trek to Madhya-Maheshwar-Kalpanath-Rudranath (3 out of Punch Kedar) in Uttarakhand.
While trekking from Dumak to Panar at 2000+ m altitude clicked this one !


Excellent photograph …  This is Arisaema propinquum.

Attaching 2 Figs of Arisaema sp,
Collected from Narkanda, in Himachal Pradesh at an altitude c.a, 7500 ft., June 20th 2007.
1. can it be A. erubescens ?
2. Is it A. costatum ?


… the 1st picture is of a Arisaema tortuosum. but the 2nd one is not so clear to id but it appears like Arisaema costatum.


First is indeed Arisaema tortuosum (erubescens has a radiatisect, umbrella type leaf where all the leaflets seem to originate from a central point) and the second is Arisaema propinquum.



Striped Cobra Lily (Arisaema costatum)

Place: Valley of Flowers

Date : 14.08.2012


In view of recent replies by Dr. Pascal in another thread, it must be something different.


Given that it comes from the Valley of Flowers it most likely is a form of propinquum but the picture is not clear. Also the growing infructescence makes the spathe tube wider than it probably is. In the griffithii/ propinquum alliance the spathe blade often remains intact for quite a while after pollination but in costatum it withers after pollination. The infructescence of costatum is much more dense with entirely green and rounder berries. Example of a costatum fruit for comparison can be found here: http://www.keepingitgreennursery.com/blogs/news/4232812-a-flowers-ugly-step-sister-seeds

Arisaema utile Hook. f. ex Schott, Prodr. 30. 1860.
Perennial herb with single basal leaf , leaflets 3,  each up to 20 cm long, rhomic-ovate, sub-acuminate; petiole up to 30 cm long; Spathe brown-purple with white ribs, curved and broadened at tip with up to 2.5 cm long tail; Tail of spadix very long, brownish, filiform, hanging down.
Photographed from below Chopta forest in Uttarakhand.  


A correction in the ID. This could be Arisaema propinquum Schott, a species closely related to Arisaema utile Hook.f. ex Schott 


Yes … Even I have received message from … confirming it to be A. propinquum.

Thanks to both …


Although there is still more fieldwork needed, this type is indeed currently considered Arisaema propinquum as … suggests correctly. The holotypes and plants growing at the holotype locality of Arisaema utile suggest it is a bigger plant with broader leaflets,  not to be mistaken with plants in the horticultural trade under that name which are brown-purple forms of Arisaema griffithii that grow in N Sikkim (Yumthang Valley). 


Thanks a lot … for detailed explanation. This one thing I also had noted that plants of A. utile are supposed to be more gigantic with darker spathes than my plants.

This one was shot from way to Valley of Flowers, Uttrakhand..
Please validate/correct the id.. Arisaema propinquum 


Now I think yes

Very good photographs.


 

This Arisaema sp was photographed in Sunderdhunga Valley of Uttarakhand, though it is common elsewhere in Uttarakhand in temperate zones.
The inflorescence part mimics the snake-hood thus plant is popularly mentioned as Snake Lily or Cobra Lily. Scary enough to an unaware visitor!


Nice photograph..perfect mimicry..


Hats off to … Realy mind blowing mimicry Sure; looks a cobra ready to strike. Congratulations and thanks for sharing. 


Can this be Arisaema propinquum ??


Yes Sir. Looks it is Arisaema propinquum 


I think yes, really good click


Thank you Sir, Thanks … I am taking it as A.proponquum.


Most probably it is Arisaema daihense an Himalayan species. However I request that another photograph showing the arrangement of leaves and their shape may also be displayed for correct identity.


Arisaema dahaiense I think with is a very distinct species with very broad wings, and recorded from Myanmar and China http://davesgarden.com/guides/pf/showimage/18158/#b

Arisaema propinquum? ABSEP2016/01 : 6 posts by 3 authors. 5+1 images.
I dug this out from my earlier walk to Triund. I am confused if this is A. propinquum or A. graffithii. Please advise.
Arisaema propinquum?
Mcleodganj-Triund Trek 2300m and above 30 May 2016 
This one is from 31st July walk;


I think Arisaema propinquum Schott for the first set.
2nd one looks different.


The first picture of the narrow, small inflorescence is what is considered propinquum. The problem is that griffithii and propinquum are not well defined species and seem to be part of a cluster of variants. Apart from the “classic” propinquum and griffithii there are numerous intermediate forms that can’t be classified well and should be considered part of a variational range between propinquum on one end, and griffithii on the other extreme. Classic griffithii has a short peduncle yet there are several forms, particularly at the edges of Yumthang valley that have peduncles well above the leaves. Appendix length (the “thread”) is also variable as is the color. I have studied this group on several fieldtrips to W Bengal, Sikkim and Nepal and failed to find stable characters to use for species delimitations, all characters vary.

Some species groups in Arisaema are in an evolutionary flux and the normal practice of well defined species in other plant genera doesn’t always apply to Arisaema so the best way to deal with it is the use the “griffithii-group” designation for the other pictures you show. We are used to be able to apply a specific name to a specific plant but that is not always possible in Arisaema. That doesn’t mean we need new names, it does mean we need new concepts of dealing with variable species groups. So I can fully understand your confusion.


Many thanks … for explaining this. I will mark them as advised.

Which Arisaema is this ?


True Arisaema propinquum, the Sandakphu area is the region the type was collected.
