Plant for ID 16/09/2011 SMP1:
Another grass for ID

Sorry for inadequate information.

If suggested I can go again and try to catch for the required characters.
A 1 foot tall grass species with characteristic unique inflorescence.

---

Paspalidium flavidum, I think.

---

Stem, leaves, racemes on the rachis, & spikelet patterns of this grass draw near to Paspalidium flavidum (Retz.) A Camus [Panicum flavidum Retz.]
Family-Poaceae
Sometimes the grass habitat description, full plant photo adds more value.

The second photograph shows that it is Echinochloa colona (L.) Link

Echinochloa colona no doubt abt it

---

Both may be Echinochloa colonum.

Grass ID request – RK19 – 16-Oct-2012:
This grass is around 2 feet high and flowering in Karjat region. Hope the pictures are okay for identification.

---

This might be Echinochloa colona (L.) Link. ….. but please do wait for experts.

---

Yes it is. Many authors also spell it Echinochloa colonum, instead of colona, as an exception to the rules of ICBN (International Code of Botanical Nomenclature)

---

Actually this should be Echinochloa colona only. Related with the gender of the plant.
There is no exception for this plant except for the fact that basionym was Panicum colonum L. so may be some people think of maintaining the gender which is usually not the accepted way.

---

Yes, I also think so. This has been published in the following link. But I have not read the whole text.

Echinochloa colona versus” Echinochloa colonum” (Poaceae)

Author: Michael, Peter W.

Source: Taxon, Volume 58, Number 4, November 2009 , pp. 1366-1368(3)
Abstract: Confusion in current botanical literature about the correct spelling of the specific epithet of the important crop weed referred to as either Echinochloa colona or E. colonum is resolved in favour of E. colona. The use of “ colonus ” as an adjective is not found in classical Latin dictionaries published since the latter part of the 19th century but is found in dictionaries, listed here, published between the late 17th and early 19th centuries. Linnaeus and other early botanists were quite in order to adopt “ colonus ” as an adjective and decline it according to the gender of the generic name, as in Panicum colonum L. and Echinochloa colona (L.) Link.

Echinochloa colonum

Paspalidium geminatum (Forssk.) Stapf Fl. Trop. Afr. [Oliver et al.] 9(4): 583. 1920.

Basionym:
Panicum geminatum Forssk. Fl. Aegypt.-Arab. 18. 1775.
Setaria geminata (Forssk.) Veldkamp Blumea 39(1–2): 377 (1994).

Echinochloa colonum as per another thread.

Yes. Echinochloa colonum

Echinochloa colona. The specific epithet is often (mis)spelt as E. colonum.

Thank you … for the ID..

.

photographed on 26-10-2009. From where you have photographed this grass. do you hav any specimen ??

It was in Khalsa College Botanical garden, plot in which we had planted rice.

Echinochloa crus-galli as per another thread.

according to me this one is Echinochloa colona not Alopecurus

That is all right to call it Echinochloa colonum also as E.crus-galli is considered by many authors as E.colonum var. crus-galli and some authors also have used Echinochloa crus-galli ssp. colonum.
The correct spelling of the specific epithet is colonum and not colona as it is not related to gender but is a contraction of ‘colonorum’

SK 3881 27 October 2023 – Grass (Poaceae): 5 very high res. images.

Echinochloa colona

As per general rules of naming plants genus and species epithets should rhyme. So, ideally when Panicum colonum was transferred to new genus Echinochloa, the right naming should have been Echinochloa colona. However, certain authors have preferred to conserve the original specific epithet colonum. So, I have seen many authors use Echinochloa colona while many others use Echinochloa colonum.
