Title: Help to identify Paris species from north east Sikkim
Post by: Johan Nilson on November 27, 2009, 11:46:00 PM

We came across different forms of Paris which I have hard work identifying! I have some guesses but is not sure at all! I would be very glad for help!

Pic 1-2 Paris polyphylla
pic 3 Paris sp( we saw this form with this angled steem on a couple times)
pic 4-6 Paris sp( I am guessing P. violacea) 
pic 7 same Paris sp (in seed)

Johan,

According to book on the genus Paris of Li Heng the following Paris species grow in Sikkim:
P. polyphylla var polyphylla, P. polyphylla var stenophylla, P. marmorata and P. thibetica.

Pics 1 and 2  are probably P. thibetica. This species has very long free connectives on the anthers which the Paris on the pics obviously have.

I don't know what pic 3 is but I would guess P. polyphylla var polyphylla (if the information of Li Heng is correct).

Pics 4 - 6 are probably what you think: P. marmorata (violacea). They also look a bit like P. pubescens (mairei), this species has hairs on the stems and on the backside of the leaves. Did you notice these characteristics on this species?

regards,

Robin

Hi Robin,

Thanks! This is helping me a lot. Very interesting that the first two pictures probably is P. tibetica.

And for pic 4-6 I came across P.violacea in 'The flora of Bhutan' and the description of a short habit 10-15 cm, variegated foliage with waverly leaf edges and underside of leaf violet. fits pretty good. (guessing that P.marmorata is the accurate name?)

I didn't see any hairs on stems or leaf undersides. But I will check my pictures once more. I have the seedlings from the seeds on pict 7, so will be able to tell in a year or two.

Do you know if its possible to get hold of Li Hengs book?

Johan,

You can also find Li Heng's book at 'nhbs bookstore' (http://www.nhbs.com/title.php?tefno=90017). Rather expensive.
I have to mention that most of the text is in Chinese.

Giles,
Did you order any of their ebooks? If so, how long did you have to wait, before you received it?

Robin,
Thanks! I just might order? A pretty good Christmas gift for myself!

Johan,
- a couple of days. Don't despair, if all else fails there is someone there who can understand English and sort things out.

Johan,
 
 I have see a few posts of your trip to Sikkim and was wondering if you came across any Polygonatum species? The Paris are beautiful.

 Do you own a copy of the Flora of Bhutan, the non-graminae monocots volume? I have tried to get a copy through a library loan, but they sent everything but that volume and I would like to see the treatment on Polygonatum. I am curious about P. brevistylum and P. nervulosum. Niether of these species are in cultivation and I do not have any herbarium specimens yet either.

 All the best,

Aaron,
Yes, we did see a lot of Polygonatums. I Posted some pictures earlier in one of all threads here, but will post again. I will be very glad for help with names!

I don't have my own copy of 'Flora of Bhutan', but I hope to get one soon ::) A friend has got a copy and I have a copy at work as well. If I have time I will try to get in to it tomorrow!

Ian,
Thanks. The seeds were sown in autumn 2007 and came up with their first leaves this spring.

Johan,

 From all the protologues of species lumped into verticillatum (kansuense, erythrocarpum, minutiflorum) I would call it kansuense, but kansuense was described from Gansu in northwest China, quite some distance from Sikkim.

 Not sure on the verticillatum thing. It looks at first glance like a pink cirrhifolium until you notice the leaf apices -- non-cirrhose.

 I'll keep looking for a better fit on them both.
