Malvaceae Fortnight- Post 53 :: Hibiscus hirtus? from Morni: NS August 38/38 : 3 posts by 3 authors. Attachments (7) Yes I think your posted plant seems to be Hibiscus micranthus as per images herein and as per keys in BSI Flora of India
There are many varieties as per http://efloraindia.nic.in/id=5689&type=4
Hibiscus hirtus only as per Keys in Malvaceae of Southern Peninsular India: A Taxonomic Monograph (Flowers white- Hibiscus micranthus, Flowers red- Hibiscus hirtus) Sorry. I think I got carried away by the colour of the flowers in the keys and did not check the calyx and other aspects. It is Hibiscus micranthus only.

I have observed Hibiscus hirtus placed in efi is Hibiscus micranthus (Ref. eflora karnataka; again the description given does not match; It is a rather rare plant; leaves trilobate; hence I am adding description with images captured in wild at Velugonda hills of Eastern ghats

Thanks, … I will shortly look into it. I think your posted plant seems to be Hibiscus micranthus as per images herein and as per keys in BSI Flora of India
There are many varieties as per http://efloraindia.nic.in/id=5689&type=4
the attached plant is Hibiscus micranthus, (H.micranthus produces white and pink flowers it is Syn of H.ovalifolius (Forsk.) Vahl,
Leaves simple less than 2cm in diam, in H.micranthus, In H.hirtus leaves partite or lobed(Please observe 2 specimens) epicalyx shorter than calyx, plants hard, stellate hairs short(not as soft as H.Hirtus); in white variety of H.micranthus the corolla is reflexed
in H.hirtus epicalyx simple, seeds cottony, plants bushy, soft hairy (It is not the colour of the flower that determines the species)
It is as per Gamble, Flora A.P By T.Pullaiah, based on these books and after cross check at BSI I have identified In H.micranthus flowers are solitary usually arise in leaf axils, Epicalyx shorter than calyx lobes Yes, this is also micranthus. Calyx and epicalyx are the key characters. Pl. go through all posts in efi site, things will be more clear. In your these images, I clearly see filiform epicalyx and calyx divided upto the middle as per keys in BSI Flora, making it micranthus.
Do you still have doubts of this being Hibiscus micranthus on account of filiform epicalyx and calyx divided upto the middle as per keys in BSI Flora of India ?
Yes, I firmly believe it is Hibiscus hirtus only; be cause we have observed the fresh specimen; some leaves are tri lobed; (H.micranthus never bear tri-lobed leaves) epicalyx are longer than calyx; the entire plant is softly pubescent, the leaf size is larger than 3cm, (As per Flora of A.P.by Pullaiah, FPM by Gamble)
Thanks a lot, …
Hope something useful comes out of these discussions.
Due to confusion in Regional Floras & BSI Flora of India, it is sure that there is a long standing confusion between the two.
Finally I think we have to rely on Malvaceae of Southern Peninsular India: A Taxonomic Monograph (I think published after BSI Flora of India).
From perusing this, you will agree with id of Hibiscus micranthus (which also has tri-lobed leaves and plant is pubescent and leaf size larger than 4 cm)
Based on this, colour of the flower only decides the species among these two, as per the keys.
I am waiting for your final views in the matter
It is Hibiscs hirtus only as per my opinion, It is up to you only May I request you pl. confirm this as Hibiscus micranthus or otherwise. Can not be sure since the key characters do not appear in close ups in images but leaves are not serrate dentate and flowers are turning to orange on fading. I am hence not familiar to this plant from eastern ghats. It does not look to be H micranthus or H hirtus either. You can see the calyx on enlarging the first image in some of the flowers. Yes, one can barely see but epicalyx is seen much longer than calyx while description says almost as long. What about other characters that do not match?
The key between two species is based on leaves.
Leaves long, narrow…hirtus
Leaves broad, short….micranthus
Other characters are overlapping.
Even if my guess is incorrect on this, the confidence level of images is poor.
Thanks, …, May I request you to pl. peruse the Monograph In a hurry I had taken the images, taking one branch for observation, it is also lost, but it is not H.micranthus, Thanks … This is going in circles. Can’t go beyond the keys given in flora and can’t challenge the monograph too.
shrub for Id 040409JM1 : 5 posts by 3 authors. Attachments (3) … Hibiscus hirtus, lesser mallow this the member of Malvaceae family namely Hibiscus ovalifolius. This is Hibiscus ovalifolius. It is shown in Flora of Indian Desert On going through FOS, p.184, I found Hibiscus hirtus to be a trailing herb, 30-50 cm high, while my pictures were from a shrub of around 1 meter high. Leaves are stated to be oblong, while it’s ovate in my case. Involucral bracts also appear quite small compared to pictures of ,.. at: http://www.flickr.com/photos/dinesh_valke/3070573874/ … may not be H.hirtus. it could well be H. ovalifolius as per …
For proper understanding and confirmation, it will be interesting to note the colour of the flower fading during the day from pink to white (as put in the above attachment).
Also, the flower shape and size is relatively different from H. hirtus as per illustration at eFlora ( http://www.efloras.org/object_page.aspx?object_id=60081&flora_id=5 )
… shows flower and leaves of H. purpurues (syn. Hibiscus calycinus, Hibiscus ovalifolius, Hibscus calyphyllus, Urena ovalifolia).
What I have at http://www.flickr.com/search/?w=91314344@N00&q=Hibiscus+hirtus&m=text are H. hirtus; they are erect, and standing normally upto a height of 1 m, to sometimes 1.5 m
I had never paid notice to “trailing herb, 30-50 cm high” described in Ingalhalikar ji’s FOS, but fits very well to what is illustrated in Kehimkar ji’s Common Indian Wild Flowers, pg. 40
About leaves, they are variable, and irregularly toothed.
Malvaceae Week-Bombyx micranthus (L.f.) Riedl.: An undershrub with serrate cordate leaves 2-3 cm, flowers solitary axillary, involucral bracts 6-8, corolla 1 cm, white when blooming in the morning, pink in the noon. Flowering in June. Capsules 6 mm, globose, seeds cottony.
hibiscus hirtus: tell you the truth, i was interestingly observing the grass in the picture, look like Ischemum indicum..
yes white flower, Hibiscus hirtus Hibiscus micranthus as per Keys in Malvaceae of Southern Peninsular India: A Taxonomic Monograph (Flowers white- Hibiscus micranthus, Flowers red- Hibiscus hirtus)
It is Hibiscus micranthus as per calyx also. many thanks for this information … posted plant is Hibiscus hirtus. Calyx appears to be cut only up to the middle (micranthus) and not up to the bottom (hirtus), between calyx lobes. Thanks …
Let us take it as micranthus based on calyx as stated in the monograph.
