KEY - I

1. Leaves 1-pinnate = L. alata Edgew.
2. Leaves 1-2-3 pinnate (bipinnate, occasionally tripinnate at base - Flora of Zambia)  = L. guineensis G. Don
3. Leaves 2-4 pinnate = L. rubra Bl. Ex Spreng
4. Leaves 2-3 pinnate, leaves setaceously hairy above, below with setaceous hairs on the nerves = L. setuligera Clarke

KEY - II

1. leaflets sessile, rachis winged = L. alata
2. leaflets petiolulate, rachis not winged = L. guineensis

KEY - III

1. sinuses of staminodial tube shallow (deep in Madagascar and Mauritius) = L. guineensis
2. sinuses of staminodial tube deep, corolla tube + staminodial lobes upto 3 mm, staminodial tube less than 2 mm = L. rubra

Thank you.

Is this a KEY to L. rubra and L. guineensis ??? -

• inside of petal RED = rubra (https://www.nparks.gov.sg/florafaunaweb/flora/2/1/2192)
• inside of petal whitish = guineensis (https://www.nparks.gov.sg/florafaunaweb/flora/4/3/4371)

GBIF doesn't support that. 

Thank you.

I think, the upload by Siva ji from Sri Lanka herbal garden https://groups.google.com/g/indiantreepix/c/wh-XdbJ_2Qk/m/kRgaaKcyvQMJ

is Leea alata Edgew, (even though Sri Lanka is not in the given distribution list) because -

• as far as I can see it is 1-pinnate leaf with sessile leaflets, elliptic-oblong to elliptic-lanceolate leaflets
• most importantly oblong stipule

for comparing -

1. KEW herbarium - http://apps.kew.org/herbcat/detailsQuery.do?barcode=K000736383
2. GBIF herb. (also sourced from KEW) - https://www.gbif.org/occurrence/912569415

Thank you.

Saroj ji's upload from Kalimpong - https://groups.google.com/g/indiantreepix/c/Qu7AqOcoHuk/m/iT4YyczCAQAJ is either L. rubra Bl. Ex Spreng or L. guineensis G. Don.

Unfortunately, the paper I am following doesn't provide description of both species. And I have no clear idea how to differentiate them without 'KEY-III" and stipule picture. Yet, I agree with the established id, as L. guineensis G. Don, because -

1. inside of petal is creamy-yellow
2. long acuminate tips of the leaflets and nerves
3. apparently longer staminodial tube

Thank you.

Attached here is an account of Leea guineensis, from "Botany of Bihar and Orissa / H. H. Haines".

Ritesh ji also provided KEY to L. rubra and L. guineensis, in my thread -

Difference between these two species lies in the stipule characters. Here is a key from Fl. Malesiana (Ser. I Vol 7):

1. Stipule a narrower wing, somewhat persistent, scar long and thin.......Leea rubra

1. Stipule obovate, caducous, leaving a broad scar..............................Leea guineensis

The paper, I am following, however provides 2 types of  stipules in L. rubra and 4 types of stipules in L. guineensis. Of-course these variations in stipules cover the entire global population of the two spp.

Thank you.

Best regards,

Surajit Koley

[surajit koley]

My first regret is that I couldn't keep Ritesh ji's word, requesting to photograph the stipule of the species in my thread - https://groups.google.com/g/indiantreepix/c/dUGQK7Tsd_k/m/C_BAQsLTRLMJ 

My second regret is that I deleted all original photographs, recorded after mid-2014,, from my computer, without taking backup.

However, I think the Leea in BSI might be L. rubra, because -

• flowers are not exactly like some other posts, here inside of the petals are red - 
• less exserted (?) staminodial tube
• oblong (?) stipule (somewhat similar stipule can also happen in L. guineensis 

[surajit koley]

This is the concluding part of my study.

I think Saroj ji's Leea from Singapore is Leea rubra Bl.ex Spreng. Its petals are red inside as in Singapore Govt. Agency site - https://www.nparks.gov.sg/florafaunaweb/flora/2/1/2192

As for all red coloured cultivated / ornamental Leaa, I would go for Leea guineensis G. Don, for they all feature petals creamy-white inside. And leaves are quite different - wavy, shiny, cuneate at base .... as in Singapore Govt. Agency site - https://www.nparks.gov.sg/florafaunaweb/flora/4/3/4371.  All other sites might have mixed up L. rubra and L. guineensis.

It is expected that flowers of L. guineensis would be "creamish yellow" when open, because the "paper", while describing Leea setuligera Clarke, notes. "very similar to L. guineensis in general appearance, and possibly frequently overlooked and confused with that species. ......"

Great work, Surajit ji

Thanks, Sir ji, it was more of my learning process than to establish any identification of relevant threads!

And, imagine, just now what I have found out !!! - 

A few words extracted from an account of Leea sambucina Willd., in the "FLORA OF TROPICAL AFRICA, Vol-I, 1868".

"A suberrect woody shrub about 8 ft high, .......... Corolla oblong, 1/8 in. deep, glabrous, bright red on the outside, yellow within or entirely orange. ......."

In the "paper", I am following, it was referred to as L. sambucina auct. non.Wild.. ...... Baker in Fl. Tr. Afr. I (1868) ...", under L. guineensis G. Don.!

Thank you.

I don't have money to replace my keypad right now

Specially, key 'B', 'N' and 'Y' refuse to feel my touch!!!

An in-depth study.  A great contribution .  

Best wishes in your efforts .

Thanks a lot, Sir ji, it was my exercise book to understand red flowered Leea.

I am very happy that you read it thoroughly.
