Suregada angustifolia

Suregada angustifolia – leaves look bit obovate

Keys from BSI Flora of India as given below are creating some doubt about it being Suregada lanceolata. Maybe Tapas ji can clarify further.

1a. Leaves obovate or oblanceolate, sharply acuminate at apex, up to 15 cm long; flowers small, few in fascicles; fruits smooth, deeply lobed, keeled on lobes, 7 – 10 mm in diam. 1. Suregada angustifolia
b. Leaves elliptic to oblong-elliptic, rounded or obtuse at apex, entire, up to 25 cm long; flowers rather large, many in cymes or clusters; fruits rough, obscurely lobed, 12 – 15 mm in diam. 2. Suregada multiflora

It may be noted that the genus Suregada Roxb. ex Rottler exhibits extra-ordinary phenological plasticity. Each species seems to be connected to some other species with endless intermediated. Hence, species delimitations in the genus are based on some tendencies exhibited by the taxa rather than sharp discontinuities or differences.

In India, we have three recognized species, as follows:

  1. Suregada bifaria(Roxb. ex Willd.) Baill., Hist. Pl. 5: 120. 1874; Ramana et al. in Phytotaxa 221: 183. 2015. – Gelonium bifarium Roxb. [Hort. Bengal. 73. 1814, nom. nud.] ex Willd., Sp. Pl., ed. 4, 4(2): 831. 1806.

Type (lectotype, designated by Ramana et al., 2015): India, Roxburgh s.n. (B-W18501-020!). Remaining original material: India, Roxburgh s.n. (B-W10501-010!).

Distribution: India (Andaman & Nicobar Islands), throughout Malesia to N Australia.

Usually recognizable by the bilocular fruits.

  1. Suregada lanceolata(Willd.) Kuntze, Revis. Gen. Pl. 2: 619. 1891. – Gelonium lanceolatum Willd., Sp. Pl., ed. 4, 4(2): 832. 1806; Roxb., Hort. Bengal. 73. 1814 & Fl. Ind. 3: 831. 1832.

Trees of Lalbagh, Bangalore – Suregada multiflora – False Lime Tree (Please Cnnfirm):

I have a post of this plant at efi thread.

I feel the leaves as well as fruit look different

Yes, …, i noticed too, specially i couldn’t find any persistent calyx in your pictures.
This could be some other Gelonium sp., please check (pages of F. B. I.) :-

I attach herewith photographs of Gelonium fascuculatum Roxb. of Flora Indica. Please note serrated apex of leaves. The same can be seen in my earlier post.
Now, please compare the following flickr images with my posts –

Thanks, … I will check it out. The name plate in Lalbagh used to be: Gelonium lanceolatum

Bush for ID Tiruvannamalei, Tamil Nadu NAW-OCT-17 : 3 posts by 2 authors. Attachments (4)
Kindly identify this bush photographed at the herbal garden, Tiruvannamalei, Tamil Nadu in September 2014.
Height of bush about 2 metres. Leaves about 8 to 10 cms. long. 

Kindly suggest if these pictures are of the male of same species or of a different species altogether. These were also photographed at the herbal park, Tiruvannamalei. Attachments (3).

These are female and male plants/ flowers of Suregada lanceolata.

http://www.theplantlist.org/tpl/record/kew-198576
the plant list claims Suregada augustifolia is a synomyn of Suregada lanceolata, which is the accepted name. maybe bsi wants to go with augustifolia for some reason.
