Seen this climbing Shrub in Mumbai.
Date/Time: 27-10-2013 / 11:30AM
Location: Mumbai
Habitat: Cultivated
Kindly help me with the ID…


Pseuderanthemum species in efi so far.


I had seen similar flowers in Blue color in Sri Lanka.
Tried searching.
The closest I could find was Pseuderanthemum hildebrandtii.
This is just a suggested id.

Please add Ruspolia in your search, species like http://www.zimbabweflora.co.zw/speciesdata/species.php?species_id=154060 also look similar. But, as you say a climbing shrub, I do not know if Pseuderanthemum can be climber. On the other hand Ruspolia (syn. Pseuderanthemum, Eranthemum) can be climber or liana.


First, I missed the word “climbing” in my 1st reply mail.
2nd, Pseuderanthemum hilderbrandtii Lindau (syn. Eranthemum hilderbrandtii C.B. Clarke) is a shrub of 3 to 6 ft.
3rd, Ruspolia seticalyx (C.B. Clarke) Milne-Redh. is also a shrub or sub-shrub
One Ruspolia hypocrateriformis (Vahl) Milne-Redh. which or var. australis of which is a straggling shrub as per commercial web sites.

Please ID this small ornamental shrub with pinkish white flowers.
Photo was taken in Sri Lanka in Dec 2013.

Ruspolia sp?


Ruspolia saticalyx.


Pseuderanthemum species


To me it seems to be species of Pseuderanthemum.


Thanks for the thread and discussion, this is another new addition to my endless new list! Ruspolia and Pseuderanthemum are sometimes synonymous, and sometimes not as far my search result goes. So, there must be some KEY to genera level which i couldn’t find. Key to Eranthemum and Pseuderanthemum can be found in efloras.

Regards


If the sender PRD is from western India and this was found “wild” or natural , it makes sense since the links  from Surajit, esp the last one shows its widely distributed in eastern states of African continent… migration of seeds is likely…
if cultivated it would be interesting to find the history of such horticultural adventures… did it happen during the british rule ?  or
did independent India’s horticulturist, florists, (cant be florists  because it seems it has not entered any cut flower markets yet) or botanists brought it over? if botanists brought it over .. then why? whats s o special or was it a whim?
I just have questions

no answers
some answers could be if one finds it listed in old (hundred years old) floras of the western Indian states….>>>.


I just discovered it was not in India but Ceylon
that may change things

Ruspolia hypocrateriformis (Vahl) Milne-Redh.
I guess this is a cultivated sps.
