Malvaceae week 09 05 2011 UD 003  Gossypium herbaceum ‘nigrum’ NYBG 08

 

Since about 1999 we had been seeing this BLACK…actually a deep violet leafed cotton with very pretty  deep pink Hibiscus like flower … in several botanical gardens and some garden clubs … but I got my chance to do some digital photo taking in 2008 at NYBG… at the height of the summer of 2008 .. the flowers were just beginning to open when I ventured in…   no pods had developed yet…  but I can tell you they are usually about two inches and look like any regular cotton pods  and burst open in October ( or there abouts)  to reveal perfectly white regular cotton puffs….

 

Family:     Malvaceae

Genus:        Gossypium

Species:         G. herbaceum

                        Our cultivar is ‘nigrum”

Binomial name       Gossypium herbaceum “nigrum”

                                  Some write it as Gossypium herbaceum  niger

 

 

This so far is a rare garden plant, people often wait for long time to swap seeds, and garden clubs are a good source in USA … some members may have some to swap…

I am just happy to look at my pictures… this plant was about  24 to 28 inches tall,  its spread about 3 feet, leaves were 6-7 inches long and 6 inches wide,   fig 2 shows that its markedly hirsuit… and perhaps even  has some glands??

Any experts on botany of cotton here?

Can you please tell us what these round dots are? 

The flowers open in morning , are 4.5 to 5 inches in diameter.,  and close at nite…   pods develop slowly, bursting open in the fall… ( see above) .

 

Enjoy.

 

Thank you

Usha di..

Since it is a a cultivar the name also has to be within single quotes. Also I think Nigra (with capital N) is preferred cultivar name and as such correct name should be Gossypium herbaceum 'Nigra' or Gossypium herbaceum cv. Nigra

    Had this been a published scientific variety (unfortunately none has been published) the name would have been Gossypium herbaceum var. nigrum (with small n and in italics).

Sir ji:

You are right, I had searched, found none... and so I thought I just
did not
know where to look... may be I still dont... but its good to know it
has
not been published...

I will definitely correct the subject line that's in my hands and my
notes... other things can not be changed I guess...
Thanks
