Is this Corchorus fascicularis or tridens? family of the Okra.
I boiled the leaves at home and it goves a oily kind of liquid.
If it is what I think than I can eat the leaves when rhey are dry and make a sauce of it.
One person of the village around me siad: you can use it for washing the dishes.
Thank for an wanswer.
For other readers in English, let's just mention that Corchorus is jute.
I am fairly sure yours is C. tridens (called nzofé in Senegal, though I think that's a Bambara word).
To differentiate that from some other species of C., I refer you to this:
"The qualitative traits expressed by leaves among accessions are significant. The serration on the margin and the setae on the leaf base may be diagnostic features of Genus Corchorus in the family Tiliaceae. Accessions NHCO3 are deeply toothed serrated. This is a distinction for this accession among the others studied. Edmonds (1991) in keys to vegetative leaf structures of the species of Corchorus in Nigeria – Corchorus olitorius, Corchorus aestuans, Corchorus fasicularis and Corchorus tridens stated that;
Leaf margin serrated, leaves without basal setae...... Corchorus fascularis
Leaf margin serrated with two basal setae…… Corchorus olitorius
Leaf margin serrated with at least a set on one side or on some leaves…… Corchorus aestuans
Leaf margin serrated with two basal setae one on each side…. Corchorus tridens"
You will see from this photo that C. fascicularis has narrower leaves than yours
This plate shows the capsules from various species of C.
You will see that the capsules of C. tridens are much more slender than C. fascicularis.
Here are detailed descriptions of your two species:
"Annual, suberect, 50-60 cm tall herb. Stem woody, with scaly bark, glabrous. Leaves 3-costate, elliptic-oblong or lanceolate to narrowly ovate, 1.5-6 cm long, 0.5-2.0 cm broad, glabrous, serrate, basal serratures not prolonged into filiform appendages, obtuse; petiole 3-15 mm long, hirsute; stipules subulate-filiform, c. 5 mm long. Cyme a fascicle of 2-5 (-8) flowers, antiphyllous, very shortly pedunculate. Flowers yellow, 5-6 mm across; bracts minute. Sepals linear-oblong, c. 1.5-2.5 mm long, apiculate. Petals oblong-obovate, as long as sepals. Stamens as many as or twice the number of petals, filaments c. 1.5-2 mm long. Carpels 3; ovary oblong-ovate to linear, 3-loculed, hairy; style short, stigma capitate. Capsules 2-5(-8) in each fascicle, sessile, 1-1.5 cm long, with 1-2 mm long entire beak, somewhat triangular, pubescent, 3-loculed, locules without transverse septa. Seeds wedge shaped, c. 1.5 mm long, angular, black, obliquely truncate at both ends."
Note that its distribution does not include Senegal
"Branched annual herb, up to 60 cm tall, erect when young, older branches spreading. Young branches compressed and angular hairless or sparsely hairy. Leaves oblong to lanceolate, up to 11 cm, hairless or sparsely hairy on the veins; margins crenate-serrate with a long bristle on the 2 lowermost teeth. Flowers in 1-3 flowered leaf-opposed clusters; sepals linear, pointed, as long as the petals. Fruit a more or less erect, cylindric capsule, straight or slightly curved, up to 4 cm long, with a finely rough surface and 3 spreading apical horns."
Note that its distribution does include Senegal
Good description of C. tridens
That includes description of its use in foods (its mucilaginous nature is useful in thickening soups).
More description and photos
At the start of this reply, I wrote 'I am fairly sure'. I cannot be certain, from the research I have done, because there are other species. Of the two you suggested, I am sure it is not C. fascicularis, and C. tridens seems very likely, but I cannot rule out other species. For a full list of C. species, see http://eol.org/pages/61159/names.
I leave you to consider the other species (since you have access to the actual plant material, and at various times of year, you can look at characters such as the setae much more efficiently than I can).
Hallo Mike, I think it is the Tridens after reading the information you gave me and the link with more information. Next time I will study the plant better. Thanks very much.
Also this plant on the photo I think I have found the name but again I am not sure is this Martinia Annua?
It is really beautifull to see this piece of earth changing in the time of rain.
Since English is not my native language, (I am from Holland) sorry for my bad writing in English.
Mike did you study in Senegal?
Thanks in advance
First, we have a problem with names...
I can't find a proper Martinia annua.
Often, that is a mis-spelling for Martynia annua, which is itself a synonym for Proboscida louisianica.
That looks like your plant in general character, but yours has very different flowers, and the leaves are also wrong. Pictures:
- as Martynia - http://www.robsplants.com/plants/ProboLouis
- as Martinia - http://www.culturegrid.org.uk/search/2437513.html
The only Martinia in The Plant List is M. polymorpha
That is also not closely related to your plant, because its flowers are very different
There is a drawing of it (as synonym Kalimeris indica) here - http://frps.eflora.cn/frps/Kalimeris%20indica%20var.%20indica.
Second, I cannot ID it, sorry.
I don't have a flora of Senegal to refer to, either online or in printed form.
Please can you check your spelling of 'Martinia annua', and tell me where you found that name. Maybe you have a spelling mistake. And if you can correct that, maybe you and I can take this further.
Otherwise, I hope somebody else can help you.
No, I have not studied in Senegal. The closest I have been is Gabon.
However, I lived in The Netherlands for a few years (when I was working for BP).
So ik spreek een klein beetje Nederlandse! (zeer klein)
Hi there Mike voor jou ook gelukkig nieuwjaar, very good.
It is like you said written wrong Martynia is the right way of spelling. I found it on the Westafricanplants database
of Senckenberg. You know why I am not sure, the English name is cats claw and if you search cats claw than you find other pictures and they don't look like my flowers. Please take a look at the database.
It was a lot of work to see al the pictures if you don't have any idea of what it is, picture by picture about 7000
I have seen. But it helps me a lot.
Dank je wel.
I tried http://www.westafricanplants.senckenberg.de but I did not succeed (the closest I got was Pedalium murex).
I tried various other resources, such as a database of lepidoptera hostplants,
and online floras of nearby countries, such as http://www.liberianfaunaflora.org/FFI/Document.aspx?p=30&ix=25&pid=3021&prcid=4&ppid=3021,
and RBG Kew (http://www.kew.org/plants-fungi/species-browser/ - Senegal not listed)
...No luck, usually because of inadequate keys/search systems.
If you wait, you may get an answer on this forum from one of the staff at the NHM.
- books, such as the Flora of West Tropical Africa (http://www.nhbs.com/flora_of_west_tropical_africa_sefno_41150.html)
- university research projects/teams, such as the Department of Plant Biology at Dakar University (http://fst.ucad.sn/index.php?option=com_content&view=article&id=131&Itemid=295)
Please, if you find out, let us know!
