Some tribes use these jobs tears for adornment..necklaces in particular, they eat it and most fun is its brewed into a country / tribal liquor… which sounds like ZUUU …
and in a weekend course on biblical plants it was mentioned that in china and Japan and may be even India.. the grain (its after all of a grass family, if I remember it) the seeds are ground up and used as flour… rich in protein and some micro nutrients (dont ask me which ones, I dont remember) … Job’s tears are quite a group of grains… best use I like is the beads use and 🙂 the country liquor, ha ha…
MOST IMPORTANT IS ITS Ant-iangiogenesis effect and overall anti cancer activity was being studies as Kanglaite…PS
I just looked it up… it is still being studied in end stage Lung, liver , GI and Pancreatic cancers in USA, no results were yet available as of November this year…


We use to make beads necklace etc.,


good, so can you take some pictures of the jewelry made of job’s tears and add them here?


Relevant feedback from another thread:
…… Coix aquatica (Orissa photo), ….
It is clear that Chionachne koenigii is definitely different from Coix gigantea even when treated as Chionachne gigantea. As per priority rule, the genus Coix will prevail over Chionachne, even if someone wants to consider both under the same genus. But there are very distinct differences between the two genera. The new combination of Chionachne gigantea with all the others being treated as synonyms is published in the revision of Chionachne in Blumea. But definitely there is some mistake. I have not yet gone through the full paper of revision of Chionachne published in Blumea. Once I get a copy of this and go through, I will respond further.


Coix aquatica !!!! 

Hmmm !!! happy to learn !!! 
Once I get the water cleared here, I shall revise ID in facebook groups …will be quite a storm !! 


assamese eat it as cooked similar to rice
they are trying to promote its use

The involucre (bead like structure formed from metamorphosed leaf sheath) has an abrupt beak, which is more a character of Coix aquatica.

Coix exploded from Hooghly: Please do not laugh at me if i did make some silly mistake. I am not used to it. I found a Coix very near my home, yesterday, and tried to dissect it! 

Let me try to ID this species based on its spikelet only!
Well, large wings on glumes of male spikelet = C. gigantea, but are those wings large enough? I am not sure because i haven’t seen Coix lacryma-jobi yet!
Species : Coix gigantea?
H & H : grass in roadside water logged ditch, about 6 feet high above the water surface
Date : 25/10/12
Place : Hooghly

Attaching more photos of this grass, recorded on 25/10/12, at the same place and of the same population.


Good work. Only two possibilities are Coix gigantea and Coix aquatica. See whether the leaves are clothed with very dense glandular bristle like hairs on the upper surface and also see if the stems are succulent and have floating roots at the nodes.


What is a floating root? how does it different from other roots
any good english (for lay people kinda ) description? and line drawings?


Visited the grass at the same place today. Could not find any hair on leaf surface and leaf base. However, the place is so densely populated by wild herbs and climbers it was not possible to see through them whether there was any floating root. It was also not possible to enter into the ditch. It appears to me that the stem is not succulent, attaching a picture (pic DSCN6667) of a stem, cut midway.
I have uprooted one, might be a branch (pic DSCN6657). I give here the stats:-
1) no hair or glandular hair on leaf
2) looks like stem is not succulent
3) seems to be no floating roots
Height : 5.5 feet, nodes 10, rooting at lower 4 nodes, diameter less than 1 cm, stem slightly compressed
leaf : blade 67 cm x 4.7 cm + 14 cm sheath, upto node, covering the stem. upper surface (very) slightly rough, under surface glabrous
It looks like that this grass is same Coix gigantea, recorded at another place, and have been identified by you in another post – https://groups.google.com/d/topic/indiantreepix/DSlTblj9k0I/discussion. In such case i would like to add that this grass is very common here, growing on roadside, ditches, uncultivated lands, low land beside rail tracks and in wasteplace.


This grass is also Coix gigantea, identified by …, also in another post/thread – https://groups.google.com/d/topic/indiantreepix/DSlTblj9k0I/discussion.


is the white pith edible for any animal ?


This grass is very common in the places i visit everyday. I haven’t seen any cow or goat eating any part of this grass. The reason may lie in –
1) these days cows or goats are not kept free, for grazing
2) usually these grasses grow in ditches on roadside and rail-tracks and in waste-places where domesticated ruminants are unlikely to visit, i think
3) there may also be some physiological aspects that i do not know


Coix is supposed to be a good fodder grass. Kindly feed the leaves/stem to cattle to check its palatibility. 


I will try to find it out, i remember this difference with Chionachne.


Our helping hands confirm today that their cows eat this grass (leaves). They also tell me that they call this grass GARGORI in Bengali. Though Coix lacryma-jobi is known as GARGORI in Bengali, i think it is a general term used for similar looking grasses.

Thanks, …  I have one type in Surat and another from Siwan, Bihar. 

They were identified as Coix aquatica and Coix lacryma-jobi respectively. 
I too believed so, based on FOI and endorsement by many knowledgeable people, on Indian Flora. 
But now, I guess, I have to post them. 


Yes. that will be better.


The broad wings of glume of male spikelet, beaked involucre as seen from the longitudinal section of involucre and the habitat (water logged ditch, 6 feet high above water surface), suggests Coix aquatica. It would be nice to see the dissected involucre of other Coix species also. A photo of the whole plant would be useful for confirmation.


Thank you Sir, and many thanks to … for the ongoing discussion.


Now , I think I have the visual cues for Coix aquatica. Courtesy … and … thank you !!!

These posts I shall be going through many many times !!!

Coix probably Coix aquatica 


…, all your posts with same subject (Coix or Chionachne ??) have been clubbed in a single mail causing confusion.
