Arundo donax L. (?) from Hooghly: A Bengali book on some selected grasses informs two similar looking grasses in West Bengal are Arundo donax L. and Phragmites karka (Retz,) Steud., the leaves of the later measure 15-30 cm x 2.5 cm (http://www.fao.org/ag/AGP/AGPC/doc/Gbase/DATA/PF000309.HTM) or 80 x 2-3 cm (http://www.efloras.org/florataxon.aspx?flora_id=3&taxon_id=200025876) or 30-80 cm long and 12-40 nun (???) (http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=200025876).
I think my species is Arundo donax L.
Species : Arundo donax L. ?
Habit & Habitat : tall grass, avg. 5 feet tall, leaves 40 cm x 3.8 cm approx.; a few at far end are more than 8 feet and with broader leaves; beside railway track
Date : 28/7/12, 9.10 A.M.
Place : Balarambati (Hooghly) A portion of description from http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=200025876 is repeated (copy-pasted along with spelling error!) in http://www.iiim.herbarium/phragmites_karka.htm The grasses there had no inflorescence at that time (yesterday), wish to keep it on my watch list.. This is Arundo donax. The most distinguishing vegetative character is the amplexicaul leaves (the leaf base circling the stem). This feature is not found in Phragmites. I have read the “amplexicaul” feature of the Arundo donax leaves, though in Bengali, not the term itself, but the leaf base circling the entire internode area. But didn’t know that Phragmites lacks this feature. I have recorded “amplexicaul” feature of the Arundo donax leaves. I learn, from a Bengali booklet on grasses, the hollow stems of this grass are used to make flutes of snake-charmers and for children. I recorded these pictures in yesterday evening. Attaching inflorescence of the same grass, same community, recorded yesterday.
I forgot my mission and meanwhile either the place was cleared by the Railway or the grasses were collected, leaving a few individuals only. 3 or 4 of those individuals are more than 10 feet high.
grass Arundo again? from Hooghly 15/11/12 sk2: The primary concern is the grass, Though it looked like images available of Phragmites karka in the net, yet i think it has amplexicaul leaves. The last three pics of inflorescence (with purplish spikelets) is from another individual, half km away from the first one.
Species : CONFUSED
H & H : about 10 feet high, stem hollow, leaves avg. 60 cm x 5 cm, both sides glabrous
Date : 14/11/12, 12.01 p.m.
Place : Hooghly Yes, it is Arundo donax.
id confirmtion is it Sachharum spontaneum???? 2 : 1 post by 1 author. Attachments (1) Habitat- reserve forest
location- Chandigarh
March. 2016
m_DSCN0008 seems to be Arundo donax Seen this bamboo at many species in Mahabaleshwar, MH in March 2020.
Not sure whether it is wild or cultivated.
Requested to please ID.
Check with Phragmites karka … Phragmites karka ?? Not a bamboo. It is Arundo donax– the amplexicaul leaf base is the identifying feature
Variegated Bamboo For ID : Lalbagh,Bangalore : 07DEC14 : AK-24 : 5 posts by 4 authors. Attachments (4). The plant uploaded seems to be Pleioblastus simonii variegatus Thanks for the suggested id. Thanks … Your observation looks more closer. There are lots of variants of variegated bamboos commonly called variegated bamboos. Isn’t it Arundo donax var. versicolor, There are several species of variegated leaf grasses including bamboos. But the amplexicaul leaf base clearly indicates that it is Arundo donax as suggested by …. .
I share images of a grass I came across today (14.2.23), at a place near Dankuni, Hooghly.
It is around 10 ft., taller than Arundo donax, that I recorded quite a few years ago, and the leaves and culms are narrower in this species.
Please, identify the species.
I guess ID is correct ! Amplexicaul leaf base is a character of Arundo donax and not in Phragmites. Another way to differentiate is to check whether the hairs are on the lemmas (Arundo) or whether the hairs are on the rachis (Phragmites)
Thank you … for explaining the differences between the two species. Hope, someday I will find Phragmites karka! . References:
