Senna sulfurea

Perennial Shrub

.

… Cassia ¿ species ?:
A large shrub of Cassia planted along an avenue near Yeoor Hills, photos taken on 22 AUG 09.
My friend … has already commented in Flickr about this plant to be Cassia spectabilis.
Please validate ID.

… ID seems correct to me. Cassia glauca, now known as Senna surattensis, has glaucus pinnate leaves, 5-petalled flowers, and flat seedpods up to 20 cm long. The habit also looks right – it is more commonly seen as a shrub.

Not Cassia fistula atleast which has distinctive cylindrical long pods. This  one seems more probably C. surratensis, the only thing that looks different  to me is the thin long stalk of pod. The specimens in our garden don’t have  such long stalks. Leaves and flowers resemble.

yesterday i id it as Cassia glauca, but some how it is missing in the thread, what do you think about my this wild guess?

in the other thread of the same topic i came to know that new name of Cassia glauca is Senna surattensis, my confusion is now clear.

it is Cassia glauca Lamk., Encyclop. Meth. Bot. 1: 647, 1785; Baker in Hook.f., Fl. Brit. Ind. 2: 265, 1879; Cooke, Fl. Pres. Bombay 1: 453, 1958 (Repr.); Almeida, Fl. Mah. 2: 179, 1998.
Synonyms: Senna sulphurea (DC. ex Collard) Irwin and Barneby in Mem. New York Bot. Gard. 35(1): 78, 1982; Pradhan et al, Fl. SGNP 244, 2005. C. surattensis Burm. f. ssp. glauca (Lamk.) K. & S. Larsen, Fl. C.L.V. 18: 102, 1980; Singh et al, Fl. Mah. St. 1: 790, 1996. C. arborescens Vahl, Symb. Bot. 3: 56, 1794. C. sulphurea DC ex Collad. Hist. Nat. Med. Casses 84, 1816. Robinia javanica Burm. f. Fl. Ind. 163, 1768 (non C. javanica L., 1753). Senna arborescens Roxb. Fl. Ind. 2: 345, 1832. C. fastigiata Vahl. Symb. 3: 57, 1974.
Common names: Karud, Motha-tarved.
C. surattensis is a synonym of C. glauca.
the pod with a beak at the other end is one of a diagnosing character very important diagnosing character is ALL 10 STAMENS ARE FERTILE.
stalked glands present on the rachis at lowermost 2-3 pairs of leaflets
i hope this may clear the doubts abt ID.

‘Cassia glauca ‘ is called ‘Motha Tarvad’ ‘मोठा तरवड’ in Marathi.
So now, we have to say… ‘Senna surattensis’  is called ‘Motha Tarvad’ ‘मोठा तरवड’ in Marathi.

I know that most of the shrubby plants (and some of the trees) formerly in Cassia were shifted to Senna approximately 10-15 years ago. Some name changes involved simply swapping the genera names; others were not as direct as the example recently discussed. Most of the tree species in Senna have rather ill-smelling (when crushed) foliage; I believe all are yellow-flowered. Cassia may be pink, red, white, yellow. I’m not certain what other characteristics were used (perhaps DNA) to separate the two genera.
The GRIN listing is generally accepted as the standard for most genera here in the USA. Here is their listing for Senna: …………………..
And for Cassia: ………………………

These lists are not, however, complete, I believe. (I cannot locate, for example, Cassia angolensis, which I believe is considered valid.) Hopefully they will provide some use here.

i say that Cassia is preffered over Senna
please visit following link
http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?9339
it is the rules and articles of ICBN-International code of Botanical Nomenclature that decides the accepted names of a genus or a species or a family.
there are many articles of the code and the plant name which is validly published as on 1 may 1753 were considered valid and correct.
however there were many ammendements done the outsoming were mentioned as code.
the latest of which is Vienna 2005.
if a plant name or a genus is (not validly) published then that the later name of the same plant or the genus which is validly published (at an later date) is given priority over the previously not validly published name. thats why we have two or more names of same plants.

… thank you very much for the information. NPGS / GRIN and KEW are best suited for me !!!

… your wild guess was correct in one sense. Cassia glauca Lam. and C. surattensis Burm.f. are both synonyms of now correctly known Senna surattensis (Burm.f.) Irwin & Barneby. At the finer level true surattensis with larger (2-4 inches) leafets in 4-6 pairs, pods 6-8 inches long and known as Senna surattensis (Burm.f.) Irwin & Barneby subsp. surattensis, whereas C. glauca Lam. (C. glauca var. suffruticosa Koenig in Flora of British India) with 6-9 pair of smaller leaflets (1-2 inches) and smaller pods (3-4 inches. is Senna surattensis (Burm.f.) Irwin & Barneby subsp. sulphurea (DC. ex Collad) Randell.
And now an interesting one. C. glauca Lam. was published in 1789, whereas C. surattensis Burm.f. in 1768, and hence latter gets priority when two are treated as same species. At subspecies level, true surattensis is subsp. surattensis (no authority, as it is automatically created name if we treat C. glauca as distinct subspecies-it is autonym). and now you will ask why not to use subsp. glauca as name. Well Cassia glauca Lam, 1789 and C. sulphurea DC. ex Collad., 1816 are synonyms, and hence former is prefered, but when transferred to genus Senna (all 10 stamens perfect) Senna glauca Roxb., is already used for a different species, and sulphurea gets preference.

I think we should follow GRIN for species which are listed (many Indian species are not) and Kew World checklist species (for families which have been ccompleted). For rest we can always develop a concensus.

---

Code has no provisions for guiding us whether all species should be placed  in Cassia, or those with all ten fertile stamens under Senna. Code also has no control over whether taxonomic synonyms like C. glauca and C. surattensis should be treated as synonyms or distinct species, or else else distinct  subspecies within same species. Code here helps us how to choose names.
We would be better placed to follow GRIN, Kew World checklist, and our  consensus, when database is updated.

Concluding this posted plant to be Senna sulfurea (Collad.) H.S.Irwin & Barneby … discussed at efi thread

Agreed …

Fabaceae-Caesalpinioideae (Caesalpiniaceae) Week: Plant for ID 10/12/2011 SMP ?Senna sulfurea:
Senna sulfurea
A small tree about 5 meters. Leaflets mostly 5 pairs.
Planted on road leading to ARAI on Vetal Tekdi.Pune.
Considering the earlier discussions I find this close to … plant IDed by … as Senna sulfurea rather than S. surattensis. Please validate.

Fabaceae-Caesalpinioideae (Caesalpiniaceae) :: Senna surattensis in Thane:
Senna surattensis (Burm.f.) H.S.Irwin & Barneby

EN-nuh — Latin form of Arabic word for a thorny bush
sur-rat-EN-sis — of or from Surat (Gujarat, India) 

Your analysis prompted me to go through the Senna PDF (Flora of China) http://flora.huh.harvard.edu/china/PDF/PDF10/Senna.pdf … the plant in my upload is quite close to Senna sulfurea (Collad.) H.S.Irwin & Barneby (syn. Cassia glauca Lam.)
Seeking clarification regarding these two points:
1) the stipules in my plant … can they be considered as linear ?
2) the clavate glands on rachis between each of lowest 3 pairs of leaflets … in description, put as 2 … can it be considered as possible variation ?
Have re-attached the relevant image files for ready reference.
If the considerations are positive, then my plant must be Senna sulfurea (Collad.) H.S.Irwin & Barneby … though aware that Cassia glauca Lam. is treated differently by the top organizations.
Your thoughts.

Yes … both your plant, and uploaded by me today, and others as Senna surattensis should all belong to Senna sulfurea. Occurrence of gland in third pair is no issue as both Revised Handbook of Ceylone and Flora of Pakistan mention glands between lower 2-4 pairs of leaflets. I got slightly confused with smaller size of leaflets in your cropped image but those in your original upload match mine.
We should now wait for some one uploading leaves with 6-9 pairs of leaflets, smaller leaflets shorter than 3.5 cm, shorter leaf (less than 15 cm long) and shorter pod (7-10 cm long) the true Senna surattensis.

Cassia For ID : Bangalore : 100814 : AK-4 : 9 posts by 5 authors. Attachments (3).
Cassia seen at a garden in Bangalore.
Species id please.

Senna surattensis (Burm.f.) H.S.Irwin & Barneby syn. enna glauca. Cassia glauca. Common name Golden Senna, Bush Senna, Glaucous Cassia

I also believe that the plant is Senna pendula

Thanks for the id of my Cassia. Is Senna glauca and Senna pendula the same?

As understood now Senna surattensis and S. glauca (now known as S. sulphurea) are two distinct species. As per Flora of China (I consider one of the most reliable):
Senna surattensis (N. L. Burman) H. S. Irwin & Barneby: Leaflets 6-9 pairs; leaves 10-15 cm; stipe of legume 5-7 mm.

Kindly identify this Senna sp (Fabaceae) 

Habit: Shrub 

Habitat: Wild, wasteland by railway line 

Sighting: Tumkur, Karnataka, about 800 msl 

Date: 21-07-2014

Comparative images of Senna species in efi 

Any close up of leaves to show the presence or absence of glands?

…, No closer images of leaves.Will try to revisit the plant and try to get some close ups.

Perhaps it is Senna siamea

Please check for Senna surattensis.

I think matches with images at Senna sulfurea (Collad.) H.S.Irwin & Barneby
