Herb for ID<\/a> : 3 posts by 2 authors. Attachments (2). <\/div>\n

Pic was taken in the month off June 2014 from Ghangariya, district Chamoli, Uttarkhand.<\/font><\/p>\n
\n<\/div>\n
There are two separate species in these picture. <\/p>\n
……………………….<\/font><\/font><\/div>\n
In the picture VPB0 2014 (with rosette of leaves and white flowers), it is Arcyosperma primulifolium<\/i> (Brassicaceae<\/i>). <\/div>\n
Thanks for sharing this beautiful and early flowering species. Both genus and species are not present in eFI.<\/p>\n
\n

<\/b><\/div>\n<\/div>\n

Thanks … for proper Id, as I was confused with Saxifragaceae<\/i> members. and sorry for couple two different species in one due to mistake. <\/p>\n

Fwd: Arcyosperma primulifolium<\/a> : 1 post by 1 author.<\/span><\/div>\n
<\/p>\n
I am currently working on naming, as best I can, the excellent photos (some are outstanding) taken\u00a0in Khumbu Himal by Marijn van den\u00a0Brink\u00a0(I have already been though, initially, another excellent set from Baltistan).\u00a0 So helpful for him to often have included several (at times many)<\/div>\n
images of most plants he photographs\u00a0incl. of Primula atrodentata<\/i> (by far the best set ever posted\u00a0on the internet). <\/div>\n
Some I can name quickly other will require a lot of attention incl. those not in flower.\u00a0 <\/div>\n
Never been to Nepal in the Spring, so a delight to get a glimpse into its wonderful mountain flora at this time of year, especially when quality images are viewed.\u00a0And the familiarity Marijn’s\u00a0images are bringing to me\u00a0help me understand better\u00a0a number of\u00a0species belonging to several genera I am\u00a0uncertain\u00a0about, found in the Indian Himalaya – so this is to the potential benefit of eFI.<\/div>\n
But the main purpose of this post is to draw attention to a little-known member of the Brassicaceae<\/i> <\/font>family (previously Cruciferae), not because it is any way rare but that fewer people get into the <\/font>mountains in the Spring months.<\/font><\/div>\n
I was able to identify the 3 images of this species from near Kothe @ 3700m<\/font> as Arcyosperma primulifolium<\/i> <\/font>see: <\/font>http:\/\/photos.v-d-brink.eu\/<\/font>Flora-and-Fauna\/Asia\/Nepal-<\/font>Khumbu-Himal\/i-kPgWDdB<\/font><\/a>.\u00a0 The altitude and <\/font>habitat plus flowering date fitted.\u00a0\u00a0 Plus this species has previously been recorded from Khumbu Himal<\/font>.\u00a0 Making <\/font>me have greater confidence in my identification.\u00a0 I have not come across this species in the NW Himalaya.<\/font><\/div>\n
I REPEAT THAT I APPROACH PLANT IDENTIFICATION LIKE DETECTIVE WORK, ALWAYS SEEKING “SUPPORTING <\/font>EVIDENCE” and encourage others to do likewise.<\/font><\/div>\n
Conventional wisdom in both the UK and India is that plant identification is generally EASY and that one can RELIABLY <\/font>identify a plant by quickly glancing at and MATCHING with\u00a0single, small, general images (which often do not show much detail) <\/font>in picture books and guides such as ‘Flowers of the Himalaya’.\u00a0\u00a0 Whilst this can work for DISTINCTIVE species, it OFTEN <\/font>leads to misidentifications. <\/font><\/div>\n
Sorry, the reality is that it is OFTEN more difficult than that.\u00a0 Frequently, such photos DO NOT reveal the essential characteristics <\/font>to ACCURATELY and CORRECTLY identify plants.<\/font><\/div>\n
There is also a FALSE expectation that one should ALWAYS be able to identify a plant from a photo.\u00a0 Sometimes it is\u00a0NOT possible.\u00a0<\/font>
<\/font><\/div>\n
The entry in eFI for this species has been correctly identified by Dr Rawat of a late-flowering example from Uttarakhand: https:\/\/groups.google.com\/<\/font>forum\/#!topic\/indiantreepix\/<\/font>UUNibp_lFSY<\/font><\/a>
<\/u><\/div>\n
Arcyosperma primulifolium<\/i>\u00a0is described (but there is no photo or even line drawing) in ‘Flowers of the Himalaya’ – they said Pakistan to Bhutan @ 2100-3600m on damp rocks. April to May flowering.<\/font><\/font><\/div>\n
There is a photo of this species in The Supplement to Flowers of the Himalaya (1997).<\/div>\n
Stewart knew the plant in N.Pakistan & Kashmir from 1800-3300m<\/font> but no records from Ladakh.\u00a0He included\u00a0a var. brevipedicellatum<\/i> based on a specimen he had collected in Poonch on wet rocks<\/font> @ 2700-3000m, published by Jafri.<\/font><\/div>\n
There are also no records for this species in the most up-to-date check-list for Ladakh nor would one expect <\/font>to find it growing there. <\/font>
<\/font><\/div>\n
I came across google images for this species (I always have a healthy scepticism for the identifications of images of plants on the internet, whether taken in the wild or in cultivation – some prove to be correct, others do not).<\/div>\n
These included two on the ‘Flowers of India site’:\u00a0https:\/\/www.flowersofindia.<\/font>net\/catalog\/slides\/Primrose-<\/font>Leaved%20Rock-Cress.html<\/font><\/a>
<\/u><\/div>\n
The second image photographed by the late Krishan Lal seems correct (and the location, the Chansil Pass in HP<\/font> tallies) but the first<\/font><\/div>\n
image has been misidentified.<\/font>\u00a0The location of Nubra Valley was highly suspicious to me and although a description has been provided this has been copied from a reference source (not ‘Flowers of the Himalaya’)\u00a0and not checked with the first image, with which it does not tally.\u00a0The two photos are clearly of markedly different plants, albeit belonging to the same family.<\/font>
<\/font><\/div>\n
It is important to stress that I have found ‘Flowers of the Himalaya’ often to not be used well.\u00a0 Too many will just attempt to match with the rather small images in this ‘guide’, flicking through the pages\u00a0 I must keep emphasising it is not a Flora with only a fraction of the total Himalayan flora described or illustrated. I find too few really check the written descriptions, which are brief summaries anyhow, so have their limitations and frequently the geographic and altitudinal range is not checked to see if it tallies. <\/div>\n
I use ‘Flowers of the Himalaya’ a great deal but it is only one of numerous sources which I refer to, printed and on-line BEFORE I propose an identification.\u00a0At best, a STARTING POINT only.\u00a0 I am not in the habit of making “wild guesses”.\u00a0 I ALWAYS have supporting evidence and any general statements I make can be SUBSTANTIATED…..\u00a0\u00a0 Though, as … rightly says, we are all FALLIBLE and can make mistakes from time-to-time.<\/div>\n
Yes, A.primulifolium<\/i> is recorded from Pakistan through to Bhutan and Nubra is within Jammu & Kashmir territory but it is not a species one would expect in the TransHimalaya. <\/div>\n
Another piece of evidence, is flowering date.\u00a0 The ‘Flowers of India’ site does not say when the first image was photographed in Nubra but<\/div>\n
I would not expect it to have been close to April or May, which also should have led to the identification being questioned.<\/div>\n
