Fruits Type/ Shape/ Size Seeds- As in Pics

Location?


My guess is Luisia trichorrhiza Blume !


I see this to be same as previous post. But I cant confirm the species Fwd: [efloraofindia:345851] Luisia species for ID_2_20_03_2020


I want to help, but that can happen only if you can provide multiple pics from multiple angles with a closeup of flower.

I need to see a pic of labellum spread out to see the side lobes. This is for all Luisia.
You cant id a Luisia with this pic.

Here are some new images of the same species, that might help you.

Petals 3-7 mm broad – L. macrotis.
Epichile widening from its base at the dividing line with hypochile. …L. macrotis.
Epichile not widening at base, not broader than hypochile. …L. primulina.
I will say this is Luisia macrotis too.

Location- Assam, Alt 90m
Habitat- Wild 
Flower- as seen in pics
Inflorescence Type/ Size- as seen in the photos
Flowers Size: 1.3-1.4 cm
Fruits Type/ Shape/ Size Seeds- not seen

An un-cropped habit photo showing foliage etc may please be posted.


Luisia primulina C.S.P.Parish & Rchb.f. ??

This is my guess. Please cross verify!


This is the main problem with saying/guessing a name. The sender thinks of it as the id.

I had already responded to this pic, but I dont know why I dont see my comments here. I returned back to recheck but the poster is happy with the name primulina!!
Anyways, this is 100% not primulina. I have seen primulina, please look at the scale of the flower (can actually be done knowing the width of leaves. Primulina is much large flowered.
There is another species, Luisia macrotis.
It is advisable to post multiple pics from multiple angles for better ID. I cant even see the leaves.

Thank you so much for the effort you all always provide to resolve the identification of species. My thanks are always to all such persons who might provide some wild guess and saying, because I think he or she at least seen my post and tried his best to resolve it. In field condition, the measurement and other data are always with the collector, so we can simply resemble the guessed species with our findings. A great salute to all you working in this field.

I am uploading here some more images that are with me. The width of the leaf is 0.3-0.4 cm. Habitat is mixed-deciduous.

Looking at the length of petals I will say this is Luisia macrotis and this is known from Assam.
Primulina petal is almost same length as dorsal sepal.

Luisia brachystachys? : 10 posts by 4 authors. Attachments (1)

Please validate the ID
Location: Assam (90m asl)

Looks matching !


It is not easy to make this genus without proper view of plant and the estimate of size.

Of course a Luisia.


Pl. post better and detailed images for proper id.

All three Luisia I saw are same to me.

Thanks for sharing. But I cant make out the species. Please dont forget to mention the locations


It may also be Luisia macrotis as per detailed postings in other threads.
Isn’t it ?


Yes sir it is possible.

One best way would be to spread up labellum and share pics with scale of all.
Luisia is not easy and I think there are many wrong names.

Help to identify this Luisia sp.
Date/Time- 17/3/2020- 9 AM
Location- Place,  Assam, Alt 90m
Habitat-  Wild Type
Flower- as seen in pics (1.4-1.5 cm)
Inflorescence Type/ Size- as seen in the photos


The habit photo showing foliage inflorescence etc. is necessary  for proper ID.  


This too Luisia trichorrhiza Blume ??

Impossible to ID like this. Trichorrhiza means rhizome has hairs. Such pics may look good, but not enough to ID luisia.


Pl. Post Other and high resolution images.

I don’t see a proper side lobe of labellum and the dorsal sepal is much shorter than the petals, petals have wing on the back, I will stick to Luisia macrotis.

Trust me Luisia is not easy to identify even with this. Next time please take pics with a scale next to it.
