Saraca asoca (Roxb.) Willd.

synonym ... Saraca indica "sensu Bedd., non L."

Saraca indica L. 

is an accepted species and not synonymous with former .Saraca asoca sensu auct.

is misapplied as synonym . 

I am not familiar with this tree and leaf looks different from what I have seen on facebook in name of Saraca asoca . 

Thailand (and SE Asia) is native for S. indica L. as well as S. declinata and S. dives . Peninsular India is native for S. asoca.

Thank you.

Does not appear to be Saraca asoca (Roxb.) Willd. as per details and images herein, as suggested by Rakesh ji.

Pl. check Saraca indica per Flora Malesiana (Flowering collections of Saraca indica can be recognized by the rather higher number of stamens (usually 6-8) and the bracteoles which are erecto-patent to spreading, not clasping the pedicel, and caducous or persistent during anthesis.) with differences as per illustration at Link. I can not check the differences as pointed out in the illustration.

Descriptions are given below:

Saraca indica 

Tree to 24 m tall and 34 cm in diam. Leaves (l-)2-4(-7)-jugate, subsessile to shortly petioled; petiole and rachis (0.5-)7-25(-35) cm long. Inflorescences up to 10(-22) cm wide, slightly pubescent or subglabrous, main branches up to c. 14 cm long, 1.5-5 mm diam.; bracts elliptic or ovate-oblong, 3-8 by 1.5-4.5 mm, caducous or persistent, puberulous and/or minutely ciliate on the margin; bracteoles caducous or persistent during anthesis, erecto-patent to spreading, broadly elliptic or ovate, 3-8 by 1.5-5 mm, glabrous or minutely ciliate on the margin; pedicels (4-) 12-20(-35) mm, the length between bracteoles and flower 7-10(-14) mm. Flowers orange yellow, to deep orange or purple, or red, articulated near the base, glabrous. Stamens (5 or) 6-8(-10); filaments 10-35 mm, often puberulous at the basal parts; anthers ellipsoid or oblong, c. 1 mm long; staminodes absent. Seeds ovoid-oblong, sometimes reniform, 4-5 by 2-2.5 cm, and 0.6-1.2 cm thick.

Asia-Tropical:, Jawa (Jawa ‒ present); Laos (Laos ‒ present); Malaya (Peninsular Malaysia ‒ present); Sumatera (Sumatera ‒ present); Thailand (Thailand ‒ present) S Vietnam: present

Thailand, Laos, S Vietnam; Malesia: Sumatra, Malay Peninsula, Java

Commonly cultivated as an ornamental

Saraca asoca

Tree up to 10 m tall and 10 cm in diam., sometimes shrub or medium-sized shrub, 4.5 m tall. Leaves (l-)4-6-jugate, subsessile to shortly petioled; (petiole and) rachis (0.5-)7-15(-30) cm long. Inflorescences 1.5-12(-20) cm wide, glabrous, main branches up to c. 6 cm long, 1.5-2 mm diam.; bracts broadly ovate, ovate or obovate, 1-6 by 1 — 3.5( — 5) mm, caducous or persistent, puberulous and/or minutely ciliate on the margin; bracteoles persistent during anthesis, erect, embracing the pedicel, never spreading more than 45° from the pedicel, ovate, elliptic, or obovate, 2-7 by 1.5-4 mm, sparsely puberulous, subglabrous or glabrous except minutely ciliate on the margin; pedicels 8-18 mm, the length between bracteoles and flower (4-)7-10 mm. Flowers obscurely or not articulated near the base, subglabrous or glabrous, orange yellow, when older deep orange or orange red, fragrant during the night. Stamens (5 — )6 — 8( — 10); filaments (10-) 17-25 mm, glabrous; anthers ellipsoid or oblong, 1.5-2 mm long; staminodes 0-2. Seeds oblong-ellipsoid, sometimes slightly reniform, 2-3 by 1.25-2 cm, and 0.6-1 cm thick.

Asia-Tropical:, Bangladesh (Bangladesh ‒ present); India ‒ present; Jawa (Jawa ‒ present); Malaya (Peninsular Malaysia ‒ present); Sri Lanka (Sri Lanka ‒ present); Sumatera (Sumatera ‒ present) Papua New Guinea: present west of the Irrawaddy R.: present

India, Sri Lanka, Bangladesh and Burma (west of the Irrawaddy R.). Introduced and cultivated in Malesia, specimens seen from Sumatra, Malay Peninsula, Java, Papua New Guinea.

The species is frequently planted near shrines, occasionally in gardens and villages as an ornamental. Its bark, leaves and flowers said to have medicinal properties .

Saraca declinata is mentioned in Flora Malesiana, but possibly not cultivated.

I can observe filaments are puberulous as mentioned in Saraca indica (glabrous in Saraca asoca). So possibly it can be Saraca indica

You may be right Mr. Garg. I did not take the image but being a very old tree

the diameter of the trunk seems to be more than 34cm.

Thank you.

[Gurcharan Singh]

Bracteoles are very necessary for final conclusion. Stamen number although mentioned as important is not applicable based on description S. indica Stamens (5 or) 6-8(-10); filaments 10-35 mm; S. asoka Stamens (5 — )6 — 8( — 10); filaments (10-) 17-25 mm.

[J.M. Garg]

I can observe filaments are puberulous as mentioned in Saraca indica (glabrous in Saraca asoca).

Confusion seems to be prevalent in GBIF also as also in other sources on net.

It is very difficult to check bracteoles position in the specimens. Otherwise also these fall off very early.
