Cyanotis obtusa : now accepted taxon


Cyanotis arachnoidea 'Tampicana' → Cyanotis obtusa (Tampicana)
What was formerly known as Cyanotis arachnoidea 'Tampicama'

Today, May 22 that I happened to check POWO, the Cyanotis obtusa is now an accepted taxon and not a synonym of Cyanotis arachnoidea anymore. So it has been transferred back to its formerly accepted taxon and it's not identified as Cyanotis arachnoidea anymore.



Therefore what was formerly known as Cyanotis arachnoidea 'Tampicana' now becomes → Cyanotis obtusa.


Here is a screenshot taken in 2017, of what was falsely labelled as Setcreasea [Tradescantia] pallida Tampicana, from Glasshouse Works. What can only be retained from that name is " Tampicana " as a common name.

However, there's another Cyanotis obtusa with narrower stems and smaller leaves. That one I have seen it labelled as Cyanotis arachnoidea var. obtusa. But that taxon is not listed as an infraspecific on the POWO website anymore.

I think more botanical work and communication between POWO and botanists needs to be done.




These were the cuttings that I was selling as Cyanotis arachnoidea (left) and Cyanotis arachnoidea 'Tampicana' (now Cyanotis obtusa).




The Cyanotis arachnoidea in my position identified by the Indian botanist and expert on Commelinaceae Mayur Nandikar.
