Ranunculaceae Week: Thalictrum reniforme (?)_RKC_04_020511: I had posted this plant long back on eFlora and it was identified as Thalictrum neurocarpum. Apologies for posting bad quality of photographs.
A/C to Tropicos, the accepted name is T. reniforme which is distributed in China, Bhutan and Nepal. I would be happy if the identity and its distribution in India is confirmed.
Name: Thalictrum reniforme Wall. (?)
Loc.: Churdhar Wildlife sanctuary, Himachal Pradesh (ca 1500m)
Date: August, 2010
Some earlier relevant feedback (from earlier thread: https://groups.google.com/group/indiantreepix/browse_thread/thread/eb5ffdab199fd7ab?hl=en):
Seems to be Thalictrum neurocarpum
Link from The Plant List:
After further critical look it appears that plant may either be T. chelidonii or T. reniforme, and needs to be rechecked again. Unfortunately there seems to be lot of contradiction between FBI and eFl of China, former reporting greenish white flowers in reniforme; according to FBI flowers are larger in T. chelidonii (25 mm diam.; only 8-12 mm in T. reniforme), but according to eFl of China sepals are 9-13 x 6-10 mm in T. reniforme and 5-8 x 2.5-4 mm in T. chelidonii. Again eFl China reports achene stipe as 0.6 mm long (achene 4 mm) in T. chelidonii and 1.5 mm (achene 6 mm) in reniforme. FBI reports stipe as long as achene in both. The illustration of eFl. of China, however, shows much smaller achene with stipe almost as long in T. reniform, and much larger achene and very short stipe in T. chelidonii
Also Fl. China reports 6-8 carpels in T. chelidonii and 15-20 in T. reniforme. FBI reports achenes numerous in T. chelidonii and only 6-8 in T. reniforme.
But the two consistent characters which need to be verified are plants, leaves, pedicels glabrous in T. chelidonii and glandular-pubescent in T. reniforme. Also there are axillary buds in T. chelidonii but absent in T. reniforme
T. chelidonii T.reniforme
1. Plants Glabrous Plants glandular pubescent
2. Cauline leaves with axillary buds Cauline leaves without axilary buds
3. Leaflets glabrous Leafletsglandular-pubescent beneath
4. Pedicel 4-10 mm long, glabrous Pedicel8-25 mm long, glandular pubescent
5. Sepals lilac or purple (FBI), pinkish (eFl China) Sepals greenish-white (FBI), reddish pink (eFl )
6. Flowers 25mm dia (FBI), sepals 5-8 x 2.5-4 mm (eFl) Flowers8-12 mm dia (FBI), 9-13 x 6-10 mm (eFl)
7. Carpels6-8, style shorter than ovary Carpels15-20, style slightly longer than ovary
8. Achenes numerous, stalk as long (FBI) Achenes 6-8 , stalk as long (FBI)
8. Achene 4mm with 0.6 mm long stipe Achene 6 mm long with 1.5 mm long stipe
T. chelidonii or T. reniforme ?
May I request you to pl. have a look.
Elevation 1500m. is correct ?
I don’t think this sp. to be T.reniforme nor T.chelidonii…
The plant here size looks quite smaller which should be much taller about 1meters in both species moreover sepal is not ovate in this sp. which should be otherwise at least 3-5mm wide in both these sp. whereas its quite narrow in this case moreover stamens are having quite long filaments in this sp….
I checked for all 13 spp. of Thalictrum mentioned in Flora of HP but still is not able to find any proper match…
Thalictrum sp from Paddar valley J&K: Kindly validate the ID
Can this plant be Thalictrum foliolosum
Location: Paddar valley J&K
Date: 2nd August 2011
Altitude: 3300 metes asl
I hope you will have to develop habit of taking close ups of flower and fruit, very imortant in this genus
Yes Sir, I will do the same in next seasons
You have such a wonderful collection but unfortunately you did’t have good camera.
I am pursuing my M.Phil in Environmental Sciences at Jammu University since March 2011. My study area is my native place in Greater Himalayan region of J&K called Paddar valley in between the valley of Pangi in H.P and Zanskar in Ladakh and Kishtwar High altitude National Park J&K. This area is rich in floral faunal diversity with no roads and electricity till date.
I have visited only 3 times in June, July and August 2011 for field study and photographed about 500 plant species but being a layman with no background of taxanomy and low quality camera the quality of photographs is not good. But I want to continue my Ph.D in the same field and I have decided to buy a good camera for the next visits. I am also unfortunate to have no expert in my deptt. in concerned field. But my passion for plant diversity forced me to choose the field. I am learning a lot from EFI especially … If possible I would also like to register in a good institution for my Ph.D. in order to have quality research. Many many thanks EFI for helping me a lot.
