Malvaceae week 0905- 9112011 UD 016  Hibiscus Yellow Weird unfurling WHY AND WHAT FOR ???

Dear All:

Familiy:            Malvaceae

Subfamiliy:           Malvoideae

Tribe:                       Hibisceae

Genus:                        Hibiscus                 

Species                           Hibiscus rosa chinensis, YELLOW

I am sending this in to ask  what is this weird set of petals in this otherwise "normal five petalled hibiscus I bought.. about 3-4 weeks into being on  my balcony this flower appeared...   only one of this weird kind ... have had five or six similar ones since then... all were like the normal first flower.... picture  is included of the first normal one...

Any ideas???  Any thing I can do to further examine this phenomenon?   Is it common?

etc etc... have many questions...

Thanks

Petaloid staminal tube can be a simply an anomaly

Tanay: nice to know the nomenclature... Petaloid staminal tube-- very apt...

Has such anomalies been been written about?  what could cause it?  or are these hybrids vulnerable to such anatomical changes... most of these hybrids of tropicals are coming from Thailand... do you think may they have inserted some mutable genes that only occasionally express themselves...

If you know of a book or paper please send me the ref... thanks


something similar happened to one of my euphorbia milli.... I'll upload the pic if I can find it...

Hi Ushadi Ji.

I am not completely aware of the perfect resason for the anomaly.

I dont think its due to an insertion of mutational gene by the horti-

culturalists, because they wont make so much efforts for a simple

garden plant. It may be due to simple chromosomal or physiological

abnormality. I am attaching a very olf paper from 1947 which deals

with similar kinds of abnormality in Hibiscus esculentus (lady's

finger). Hope you will enjoy reading it.
