Fruits & Vegetables Week: Rumex dentatus,:
Rumex dentatus, a weed of cultivation and growing in waste places is often used as vegetable, a rich source of Calcium, beta carotene, vitamin A and vitamin C.

Local Names
Hindi: Ambavah, amrule
Delhi: Lal bibi, jungli palak

It becomes a nuisance when it comes along with wheat. You might be aware that this is troublesome weed in wheat harvesting areas of our region. I actually didn’t know about it being used as a vegetable.

Since there has been a lot of discussion in another thread about the use of Alstonia scholaris wood for making slates for school children (hence the name scholaris), those who must have used wooden slates (Takhti) must be knowing that there are two ways of doing this:

1. First ways is to smear the surface of slate with a suspension of white clay, allow it to dry and then write with normal ink using wooden pen (kalam)…… black on white.
2. Second way includes moving slate over a flame of oil lamp in such a way that it gets covered with soot. The next step is to rub the fresh leaves of Rumex so that the soot sticks firmly on the slate, and then rub back of
inkpot on the slate to give it a shine (ghota). This black slate is then written on using the suspension of white clay………white on black

I used a real slate. I wish i had made my own slate the way you have described. My grandfather told us about Dhulpati. The used to spread dust over a plate and write in that. The wooden pen (kalam) you are writing about, is a wooden pen? My father used to use Boru, which is made from Bamboo.  But kalam ist different is it?  I don’t have a boru here with me and can’t post a foto of it. But i have the squeak sound of it in my ears.

The kalam I am talking about is usually made of cane (Arundo donax in Kashmir; Saccharum spp. in warm climate), oblique cut at one end with split tip like we have in ink pen.

As what I remember we had  both Boru and Tak in childhood. According to my memory Boru is made up of a reed grass/ bamboo whis is hollow, thin. It used to one internode ( as per present scientific knowlege) long. It had the slanting tip which had to be dipped in ink (Royal ink/ Camlin ink, if you remember) and then to be writen on the paper. The tip used to get warn off and we used to sharpen it. Tak was a solid rod of wood, on the tip of which use to be fitted a mtalic Nib, which was dipped in ink and written on paper. For this we used to carry ink bottles to shool and many a times spill it on uniforms, those days we never had Surf Exell. As per my undersanding Kalam is a urdu word which is used for pen like object with which we write. I donot knw seperate wors for Boru and Tak in Urdu or Hindi. As for slate we also used to have real slates which we use to shine(Ghota with the coal. Every sunday was that programme. On this we use to write with pencil of some cabonate.

I feels good to to peep into the past childhood. Yes you reminded me, from the hollow kalam (made from a cane which could be Arundo, Acorus, Saccharum, Bamboo, etc.) we migrated into early pens consisting of a solid wooden rod with a narrow tip into which we would fit a special metallic nib having nib at one end and ring at the other which would fit into the rarrow end of wooden rod. I don’t remember any special name for that (like your TaK) but have used them in plenty on paper, before we started using regular plastic pens.

Yes, you are right …  This is a very common and noxious weed of our wheat crops

I think yes. Nice photographs …

A reply from … at Rumex (Polygonaceae) page with comparative images:
For R. dentatus I’ve attached the description I have (and the related R. pulcher) which is that it is an annual with 0 or few twiggy branches, the species having a “stiff” look. The last five R. dentatus photos on the page seem to depart from that description. The 1st pic of all those presented for R. dentatus does give a much more fitting presentation of those qualities to my mind. Beyond my reading I’ve no special experience of the species so others may know better.

I have gone through the images at our species page at Rumex dentatus L.

It appears in line with other observations at the page.
Fruits also match with others.
It is possible that there are many plants of the same species giving an impression that it is a single plant with spreading branches from the base.

This another tall herbaceous Rumex species was found growing in Gulmarg meadow in Kashmir alt. 2500 m. The plant has valves which are entire but have 2-3 pairs of straight teeth towards base. The two species I can think are R. punjabensis and R. maritimus. Kindly help in exact identity.

All the photographs you have displayed are Rumex dentatus and it varietes which have been recently raised as sub species.

It’s very difficult to identify with such incomplete pictures.

Please follow the guidelines for proper follow up of your posts..
The picture posted here looks closer to Rumex than any Lamiaceae..

I hope Rumex dentatus
