Climber For ID : California : 18NOV14 : AK-38 : 10 posts by 5 authors. Attachments (5)

Climber seen in San Francisco on 1st Oct,14.

Looks like a Ivy Creeper.


cissus sp


Any Parthenocissus species – a suggestion.
(Parthenocissus tricuspidata variant ?)


i still think its boston ivy


Hedera helix.


Thanks for the id. Initially, I had thought of Ivy too, but had never seen it flowering.
That’s the reason I wasn’t sure. 


Yes Hedera helix, very commonly grown as cover plant in California


Thank for validation. I should have guessed it myself.
  

This is a tree from Manali.

Looks like Hedera helix, a climber. 


Hedera nepalensis


This should be a climber on a tree.


We also found the same or similar woody climber in Dhanaulti, Uttarakhand, at altitudes of about 2500 m. Since we found it growing absolutely wild, I presume it to be the native species Hedera nepalensis. We found the leaves to be leathery, which agree with H. nepalensis. I was trying to find something to distinguish it from Hedera helix which is an alien invasive species, and could have become naturalized here.
In pictures of Hedera helix, like the following:
http://calphotos.berkeley.edu/cgi/img_query?enlarge=0000+0000+0909+1829
the leaves don’t appear to be leathery. The description at PIERS does not mention that the leaves are leathery, so I guess they are not
http://www.hear.org/pier/species/hedera_helix.htm
Thus I conclude my species to be Hedera nepalensis. Please validate.

About … plant, I feel it should be Hedera nepalensis, although from the pictures I don’t know how to rule out H. helix.

Hedera nepalensis- juvenile leaves

Hedera helix juvenile leaves

/wp-content/uploads/2020/10/Hedera-helix-juvenile-USA.jpg


The Himalayan Ivy H. nepalensis is different from European Ivy H. helix in first presence of scaly pubescence (and not stellate), fruit golden yellow (not black).

Also the juvenile leaves of H.helix are broader and regularly 5 lobed, whereas in H. nepalensis the juvenile leaves are narrower and with two to five small lobes on each side, also the leaves are greyish between the lateral veins..
Attaching the leaves of both species. H. helix grows just outside my door here.


Thanks for the information on the difference between the two species. Unfortunately our present situation is not helped by it, as … and us, both have photographed only unlobed leaves, no fruits and the nature of pubescence can’t be distinguished from our pics.

I think the following photographs of flowering shoots should help. The leaves in flowering shoots in H. helix are almost as broad as long, and flowers are greenish yellow. In H. nepalensis the leaves are much longer than broad (as seen in your and Prashant ji’s both sets) and flowers golden yellow (clearly seen in …plant).

Another climber taken at Srinagar on the 12th of Sept,11 at the hotel premises.
Again Ivy Creeper?


Yes this is Ivy Creeper with variegated leaf !!


Hedera helix may be.


I fear it may not be H. nepalensis. It may be Hedera helix.


Actually the identification in this genus is based on juvenile leaves and flowers. Mature leaves look alike, and they may be variegated in cultivars of H. helix.
